Ford F-150 Lifted Tire Guide: 33s, 35s, 37s, and Beyond

A leveling kit and a set of 33s is the most popular mod on the Ford F-150, and it is also the one where the most money gets wasted on tires that rub, ride rough, or wear out in 15,000 miles because the owner guessed instead of measured. This guide covers what actually fits on a lifted F-150 (2015 and newer) at every lift height, how the driving experience changes as you step up from 33" to 35" to 37", and which Atturo tires are available in every flotation size. If you are looking for OE replacement tires on a stock F-150, see the companion guide: Best Tires for the Ford F-150: A Fitment Guide by Driving Style.

Pick Your Diameter in 30 Seconds

33-inch (leveling kit, bolt-on clean): The entry point for lifted F-150s. Fits with a 2" to 2.5" leveling kit on most wheel and offset combinations, trim stays stock. Aggressive enough to change the look, practical enough to stay daily-drivable. Atturo offers 33s in M/T, X/T, ATS, and MTS across 17", 18", 20", and 22" rims. MSRP from $311.

35-inch (leveling kit + trimming, or 3"+ lift): The sweet spot for F-150 builds that want real presence while keeping the stock suspension. Fits with a 2.5" level and minor trimming on most setups, or clean with a 3" to 4" suspension lift. Available in the widest range of Atturo models (M/T, X/T, ATS, MTS) across 17" through 26" rims. MSRP from $344.

37-inch (4"+ suspension lift, trimming required): Serious off-road territory. Requires a proper suspension lift (4" minimum), aftermarket upper control arms, and trimming. Changes the truck's character entirely: slower acceleration, wider turning radius, more road noise. Worth it if you use it. Atturo covers 37s in MTS, X/T, M/T, ATS, and BOSS. MSRP from $404.

38- and 40-inch (5"+ to 6"+ lift, full build): Trail Blade BOSS territory. Three sizes: 38x14.50R20LT ($526.60), 40x13.50R17LT ($559.40), and 40x14.50R20LT ($587). If you are reading this bullet point, you already know what you are doing.

What Fits: Lift Height, Tire Diameter, and the Truth About Rubbing

The most common question in every F-150 forum is: "What is the biggest tire I can fit?" The honest answer depends on three things: your lift height, your wheel offset, and how much trimming you are willing to do. The community has been running these combinations for over a decade, and the patterns are well established.

Stock 4x4, factory height: The F-150 comes from the factory with roughly 2" to 2.5" of rake (front lower than rear). On stock wheels with stock offset (+44mm on most trims), you can fit up to a 33" tire in narrower widths (285mm/11.2") and everything clears. Going wider (12.50") on stock wheels at stock height pushes clearance limits at full steering lock.

2" to 2.5" leveling kit: This is the most popular starting point. A leveling kit raises the front to match the rear, opening up clearance for larger tires. With stock or mild aftermarket wheels (+18mm to +44mm offset), 33x12.50 fits clean on most setups. 35x12.50 is possible but typically requires minor trimming of the front crash bars and inner fender liner. The wider the wheel and the more negative the offset, the more trimming you need. A 33x11.50" on stock-offset wheels is the conservative safe bet that fits every leveled F-150 straight out of the box.

3" to 4" suspension lift: A proper suspension lift (a full kit, beyond spacers) gives you the room for 35" tires with all trim intact in most configurations. 37s become possible with trimming and aftermarket upper control arms. This is where the build starts requiring supporting modifications: upgraded UCAs, potentially regeared differentials, and a front-end alignment after install.

6"+ lift: Full suspension lifts of 6 inches or more open the door to 37", 38", and 40" tires. At this level, the truck is a purpose-built off-road platform. Load capacity, driveline angles, and brake proportioning all need attention. The Trail Blade BOSS was designed for exactly this kind of build.

One rule applies at every level: wider tires need more clearance than taller tires. A 35x12.50 (12.5" wide) is harder to fit than a 295/70R18 (11.6" wide) even though both are roughly 34" tall. If you are on the edge of clearance, going narrower is the safer move. And always verify fitment on your specific truck, because factory tolerances, crash bar positions, and UCA geometry vary by year and trim.

33-Inch Tires: The Entry Point

Thirty-three-inch tires are where most lifted F-150 builds start, and for good reason. On a leveled truck with 17" to 20" wheels, 33s fill the wheel wells while keeping the truck's proportions in check. The ride stays close to stock (maybe 1 to 2 mpg loss), the speedometer stays within a reasonable margin, and you gain real ground clearance and off-road capability over the factory 31" to 32" rubber.

The driving experience difference between rim sizes at 33" comes down to sidewall. A 33x12.50R17 has 8" of rubber between the rim and the ground (that is a lot of flex and cushion). A 33x12.50R20 has 6.5". A 33x12.50R22 drops to about 5.5". More sidewall means more comfort on rough roads and more flex for off-road traction. Less sidewall means sharper steering response and a more aggressive street look. Both work. It depends on whether the truck works harder on the trail or on the highway.

Atturo in 33-inch:

Trail Blade ATS is the all-terrain option with 3PMS certification (2024+ production), 50,000-mile warranty, and the Quartermaster Knives sidewall. Available in 33x12.50R17 ($311.50), 33x12.50R18 ($345.50), 33x12.50R20 ($343.30), and 33x12.50R22 ($388.60). The ATS holds a 4.8 average rating across 55+ reviews on SimpleTire and strong owner feedback on Walmart for quiet highway manners with aggressive looks.

Trail Blade X/T bridges all-terrain and mud-terrain with a 45,000-mile warranty. Available in 33x12.50R18 ($348.80), 33x12.50R20 ($356.50). The X/T holds a 4.6 average across 390+ reviews on SimpleTire. Owners on F150Forum.com and other truck forums consistently praise its balance of off-road capability and on-road composure for a hybrid tire.

Trail Blade M/T is the pure mud-terrain with deep tread voids and 3-ply sidewall. Available in 33x12.50R17 ($321), 33x12.50R18 ($329.60), 33x12.50R20 ($339.50), 33x12.50R22 ($347.60). The M/T holds a 4.3 average across 195+ reviews on SimpleTire.

Trail Blade MTS adds wider tread (13.50" width) and 10- to 12-ply construction depending on size for heavier loads. Available in 33x12.50R18 ($346.80) and 33x13.50 widths across 20" ($384.30), 22" ($388.40), and 24" ($388). The MTS holds a 4.5 average across 19 reviews on SimpleTire.

"We have bought two sets of these tires for two different vehicles. Both trucks and they have been great. First set over a year old and we live in the Midwest so they have been through every season and have been great in all weather conditions."

35-Inch Tires: The Sweet Spot

If 33s are the entry point, 35s are where a lifted F-150 starts looking like it was born for the trail. The visual difference is immediate: the truck sits taller, the wheel wells fill out completely, and the stance goes from "leveled" to "lifted" in a way that turns heads in a parking lot. The performance difference is equally real: more ground clearance, more sidewall protection for off-road, and a contact patch that handles loose terrain with genuine confidence.

The trade-off is also real. Expect 2 to 4 mpg loss compared to stock tires (depending on driving habits and tire weight), a noticeable difference in acceleration (the engine has to spin more mass on every rotation), and more road noise (especially with mud-terrain tread patterns). A re-gear to 4.56 ratios helps recover the lost acceleration on trucks with 3.31 or 3.55 factory gears, but that is an additional investment.

At 35", Atturo offers the widest model selection of any diameter. Every Trail Blade model except the BOSS is available in 35-inch sizes, across 17" through 26" rims.

Atturo in 35-inch:

Trail Blade ATS starts at R18 in 35-inch (available in R18/R20/R22/R24/R26). In 35x12.50R18: $365.70, 35x12.50R20: $383, 35x12.50R22: $401.10, 35x12.50R24: $439.80, 35x12.50R26: $536.50. The widest rim range in this diameter.

37-Inch Tires: Serious Off-Road Territory

At 37 inches, the F-150 crosses the line from "truck with big tires" to "purpose-built off-road machine." This is Raptor territory (the Raptor comes from the factory on 37x12.50R17LT), and running 37s on a regular F-150 means the truck needs to be built to support them. A 4-inch minimum suspension lift. Aftermarket upper control arms. Trimming. Potentially regeared differentials. The speedometer needs recalibration (a 37" tire is roughly 15% larger in circumference than the factory 32", so the speedo shows 85 when actual speed is 100). The turning radius grows. The ride gets firmer.

All of that is the cost of entry. The reward is a truck that can go places only 37s can reach: deeper mud, higher obstacles, steeper approaches. If the truck's job is trail running, rock crawling, or weekend expeditions on unimproved roads, 37s deliver capability that skill alone simply will never match on smaller rubber.

Atturo in 37-inch:

Trail Blade BOSS is purpose-built for this segment. Available in 37x12.50R17 ($438, or $473 in RWL) and 37x13.50R18 ($490.30, or $528.90 in RWL). The BOSS features oversized tread blocks, split center block flows for water and debris evacuation, and a knife-blade sidewall design that extends tread into the sidewall for protection during air-down conditions. The BOSS holds a 4.7 average across 18 reviews on SimpleTire.

Trail Blade MTS is available in 37x12.50R17 ($404.40) and extends into the 13.50" width with 37x13.50R24 ($515.80) and 37x13.50R26 ($602.40) for large-wheel builds. Trail Blade X/T covers 37x12.50R17 ($404.40). Trail Blade ATS offers 37x12.50R20 ($409.50) and 37x13.50R18 ($409.30, or $423.70 in RWL). Trail Blade M/T covers 37x13.50R18 ($432.50, or $435.50 in RWL), 37x13.50R20 ($462.20), and 37x13.50R22 ($473.90).

At 37", the choice between 12.50" and 13.50" width matters more than at smaller diameters. The 13.50" width adds roughly an inch of contact patch, which improves flotation in sand and mud. It also adds weight (typically 5 to 8 pounds per tire) and needs a wider wheel (10" to 11" recommended). For trail use and mud, 13.50" is the better tool. For a daily-driven lifted F-150 that sees occasional off-road, 12.50" keeps the weight and width more manageable.

38-Inch and 40-Inch Tires: Trail Blade BOSS Only

Three sizes. One model. The Trail Blade BOSS in 38x14.50R20LT ($526.60), 40x13.50R17LT ($559.40), and 40x14.50R20LT ($587). The 38" sits between 37s and 40s and is a smart pick for builds with a 5-inch lift that want maximum rubber with a touch less commitment than a full 40. The 40s are the largest tires Atturo makes, designed for full-build off-road trucks with 6"+ suspension lifts. If your F-150 is built to this level, the BOSS delivers the deepest tread voids, the most aggressive shoulder design, and the highest load capacity in the Atturo lineup.

How Rim Size Changes the Driving Experience

At every tire diameter (33, 35, 37), you choose a rim size. That choice changes the driving experience more than most people expect. The tire's overall height stays the same. What changes is the ratio of rubber to metal, and that ratio affects everything from comfort to cornering.

More sidewall (smaller rim, e.g. 17"): softer ride over bumps and washboard, more flex for off-road traction (the tire conforms to rocks and ruts), better protection against rim damage on trails, and a more traditional truck look. The trade-off: slightly less precise steering on pavement, and the tire can feel "squirmy" at highway speeds if you push it.

Less sidewall (larger rim, e.g. 20" or 22"): sharper steering response, more aggressive street appearance, and a firmer ride that some drivers prefer for highway towing. The trade-off: the rim is more exposed to trail damage (one bad rock and you are buying a new wheel), less flex for off-road traction, and a harsher ride on rough surfaces.

For a daily-driven lifted F-150 that sees occasional trails, 17" or 18" rims with maximum sidewall is the practical choice. For a truck that lives on pavement and wants the lifted look purely for street presence, 20" or 22" rims deliver exactly that. This is a driving-style decision, and every option works.

Frequently Asked Questions

What is the biggest tire I can fit on my F-150 with a leveling kit?
With a 2" to 2.5" leveling kit on stock wheels (+44mm offset), 33x12.50 fits most F-150 configurations (2015+) and the trim stays stock. 35x12.50 is possible with minor trimming of the front crash bars and inner fender liner. The wider the wheel and the more negative the offset, the more clearance issues you encounter. A 33x11.50" on stock-offset wheels is the conservative safe bet. f150forum.com and f150gen14.com have extensive fitment galleries with specific year/trim/wheel combinations.

Do I need to regear my F-150 for 35s?
It depends on your factory gear ratio. F-150s with 3.31 gears will feel sluggish on 35s (especially the 2.7L EcoBoost). Trucks with 3.55 gears handle 35s adequately for most drivers. A regear to 4.56 ratios restores the factory feel on 35s and is strongly recommended for 37s. The 5.0L V8 and 3.5L EcoBoost handle 35s on 3.55 gears better than the 2.7L, but all engines benefit from regearing at 37".

What is the difference between 12.50" and 13.50" width?
The 13.50" width adds roughly one inch of contact patch compared to 12.50". This improves flotation in sand and mud, increases traction on loose surfaces, and gives the tire a more aggressive stance. It also adds 5 to 8 pounds per tire, needs a wider wheel (10" to 11" minimum), and increases road noise. For trail use and mud, 13.50" is the better tool. For daily driving with occasional off-road, 12.50" is more practical.

Which Atturo tire is best for a lifted F-150?
It depends on your primary use. Trail Blade ATS for the best balance of on-road comfort and off-road grip (all-terrain, 3PMS certified, 50K warranty). Trail Blade X/T for a more aggressive hybrid that bridges all-terrain and mud-terrain (45K warranty). Trail Blade M/T for dedicated mud and trail use. Trail Blade MTS for maximum load capacity and puncture resistance (10- to 12-ply depending on size). Trail Blade BOSS for extreme off-road and the largest available sizes (37" to 40"). atturo.com/sizing

Do Atturo tires come with a warranty in flotation sizes?
Yes. Trail Blade ATS: 50,000-mile warranty. Trail Blade X/T: 45,000-mile warranty. Trail Blade M/T and MTS: 3-year limited manufacturer warranty (time-based coverage, the industry standard for mud-terrain tires). Trail Blade BOSS: 3-year limited manufacturer warranty. All warranties require proof of purchase and proper maintenance (rotation, alignment, inflation). atturo.com/warranty

Are Raised White Letter (RWL) tires different from standard? 
RWL variants have the same tread pattern, compound, and construction as the standard black sidewall version. The only difference is the white lettering on the sidewall, which is a cosmetic choice. RWL variants carry a modest price premium ($15 to $40 per tire depending on size). Available in select Trail Blade M/T, X/T, ATS, and BOSS sizes.

Where can I buy Atturo tires in flotation sizes?
Atturo flotation sizes are available through SimpleTire, Discount Tire, Walmart, Tire Agent, and authorized Atturo dealers. Use the Atturo sizing tool to see every model available in your specific size.
