Best 37 Inch Tires

A 37-inch tire is not a casual upgrade. It demands a lifted truck, a re-gearing plan, and a budget that reflects the engineering required to keep that much rubber gripping the ground at highway speeds. The buyer solving this problem is usually running a rock crawler, a dedicated mud rig, or an overland build that needs clearance over obstacles no stock tire can swallow. The question is not whether the diameter helps — it always does — but which casing, compound, and tread pattern will deliver traction without shredding your wallet or your daily commute.
What separates a worthwhile 37-inch tire from a money pit comes down to ply rating, tread compound durability, and whether the construction matches your actual use case. A ten-ply mud tire that rattles on pavement and wears unevenly is a poor buy for someone who drives to the trailhead. A six-ply all-terrain that blows out on a sharp rock is a poor buy for a crawler. The options in this roundup span that entire spectrum, and in 2026 the gap between bargain and premium has widened noticeably, making it worth comparing every published spec before committing.

How We Picked
We evaluated these tires on four criteria that matter most in the 37-inch segment: construction strength relative to price (ply rating per dollar), wheel compatibility and whether the listed size matches a practical fitment for common trucks, tread compound and pattern as described by published owner feedback on wear and traction, and overall cost to outfit a full set versus a single replacement. Products that offer transparent specs and consistent owner sentiment ranked higher than those with vague marketing language.
The 8 Best 37 Inch Tires in 2026
Landspider Rocktraxx M/T (4-Pack)
Landspider bundles four Rocktraxx M/T tires at a price that undercuts most premium mud-terrain sets by a wide margin. The ten-ply construction is the headline spec: it provides a stiff sidewall that resists punctures on jagged rock without the weight penalty of a twelve-ply casing. Owners report aggressive shoulder lugs that bite well in soft mud. The trade-off is road noise and a ride that feels harsh on pavement, which is typical for this tread style. If you run a dedicated off-road truck and need a full set without paying four-figure prices per tire individually, this package solves the problem directly. Skip it if you drive more than a few miles on highway each week.
- Pro: Ten-ply construction at a bundled four-tire price
- Pro: Deep shoulder lugs rated well by owners for mud traction
- Con: Road noise and harsh ride quality on pavement
ATTURO Trail Blade MTS
At $225.07 for a single tire, the Trail Blade MTS is the cheapest way to get a 37-inch mud-terrain footprint on a 17-inch wheel. The eight-ply rating is lighter than most competitors here, which means a softer sidewall that conforms to rocks but offers less cut resistance. Owner feedback highlights the aggressive tread pattern as a positive for pure mud and loose gravel, while noting the compound wears faster than expected under mixed use. This tire suits a builder who needs one spare, is experimenting with a 37-inch setup on a budget, or runs a show rig that sees occasional trail use. Skip it if you need four tires and expect them to last more than a season of hard driving.
- Pro: Lowest single-tire price in this roundup
- Pro: Eight-ply rating keeps weight down for easier rotation
- Con: Faster tread wear reported by owners in mixed use
Atlander Roverclaw M/T I (4-Pack)
The Roverclaw M/T I arrives as a four-tire bundle on a 20-inch wheel with a twelve-ply rating, the highest construction count in this list. That casing provides maximum sidewall rigidity for rock crawling and heavy loads, and owners describe the tread as wide and blocky with strong self-cleaning in mud. The 13.50-inch width gives a larger contact patch than most rivals here. The trade-off is a stiffer, noisier ride and a price of $1116.93 for the set. This suits a heavy truck or trailer towed off-road where load capacity and puncture resistance outweigh comfort. Skip it if your vehicle sees daily highway miles or if the 20-inch bolt pattern does not match your current wheel.
- Pro: Twelve-ply construction for maximum rock and puncture resistance
- Pro: 13.50-inch width improves traction on loose surfaces
- Con: Stiff, noisy ride unsuitable for highway commuting
AMP Terrain Attack A/T A
AMP’s Terrain Attack A/T A is the only all-terrain option in this lineup, making it the practical choice for a 37-inch owner who actually drives on pavement. The ten-ply construction provides durability without the full-race stiffness of a mud tire, and the 126R load rating supports heavy trucks at highway speeds. Owners praise the tread’s ability to clear light mud and snow while remaining quiet on road. At $289.06 per tire, it sits between the budget and premium brackets. This tire is for the daily driver who wants a 37-inch stance without sacrificing comfort or mileage. Skip it if your primary use is deep mud or rock crawling where an M/T tread is mandatory.
- Pro: All-terrain compound balances highway comfort with off-road grip
- Pro: 126R load rating handles heavy trucks at speed
- Con: Shoulder lugs are not aggressive enough for deep mud
Kanati Mud Hog M/T (4-Pack)
Kanati positions the Mud Hog as a budget-conscious mud-terrain set on 20-inch wheels, and at $1064.93 for four tires it undercuts several rivals in the same size bracket. The ten-ply construction and 126Q load rating match more expensive options. Owner reviews frequently mention the wide, scooped tread design that clears mud effectively, though some note the sidewall lettering is less refined than premium brands. This is a sensible full-set purchase for a dedicated mud rig on a 20-inch bolt pattern. Skip it if you need a tire that performs well on gravel roads or if you want the brand recognition and support network of an established manufacturer.
- Pro: Ten-ply mud-terrain construction at a competitive four-tire price
- Pro: Wide scooped tread rated well for self-cleaning in mud
- Con: Less consistent sidewall aesthetics compared to premium brands
Vantage M/T
The Vantage M/T claims all-season usability in a mud-terrain tread, which is unusual at this diameter and ply count. Ten-ply construction, 126Q load rating, and a 20-inch wheel size make it a spec match for the Kanati and Atlander options here. At $269.74 per tire, buying a full set remains under $1100. Owner feedback on the all-season compound is mixed: some report adequate snow traction for a mud tire, while others question whether the compound truly holds up across temperature extremes. This tire suits a builder who wants one set to handle occasional winter drives and weekend mud. Skip it if you need proven cold-weather performance or pure mud capability.
- Pro: All-season compound claim in a mud-terrain footprint
- Pro: Ten-ply construction and 126Q rating for heavy use
- Con: Owner reports on winter performance are inconsistent
BFGoodrich All-Terra T/A KO2
The KO2 is the most recognizable name in this list, and its six-ply C construction reflects that reputation: it is a premium all-terrain tire built for owners who prioritize longevity and on-road manners over raw mud capability. The 116S speed rating is the highest here, confirming it is engineered for sustained highway travel. Published specs and decades of owner feedback consistently rank this tire for tread life and even wear. Pricing is not publicly listed as a fixed figure in this product data, which reflects its position in dealer and regional markets. Skip it if you need ten-plus ply puncture resistance or an aggressive mud pattern.
- Pro: Industry-leading tread life and even wear from owner reports
- Pro: 116S speed rating supports confident highway driving
- Con: Six-ply casing offers less puncture protection than mud-terrain rivals
Toyo Open Country M/T
Toyo’s Open Country M/T is the established choice for buyers who want mud-terrain traction with a reputation for durability. The eight-ply construction and 124Q load rating on a 17-inch wheel make it lighter than ten-ply rivals, which some owners prefer for easier rotation and reduced unsprung weight. At $500.07 per tire, a full set costs significantly more than the Landspider or Kanati bundles but comes with the backing of a well-known manufacturer and a broad dealer network. Owner feedback consistently praises the tread life for a mud tire. Skip it if budget is your primary constraint or if you need the stiffness of a ten-ply casing for heavy rock use.
- Pro: Proven tread life and strong owner satisfaction across years of use
- Pro: Eight-ply rating reduces unsprung weight versus ten-ply options
- Con: Per-tire price makes a full set substantially more than bundled rivals
Buying Guide
Ply Rating and Load Index
In the 37-inch segment, ply rating ranges from six (all-terrain) to twelve (heavy mud). Higher ply means a stiffer sidewall that resists cuts and punctures on sharp rock, but it also means a harsher ride and more road noise. Match the ply to your primary terrain: eight or ten ply for mud and mixed rock, six ply if you need highway comfort. The load index (124Q through 126R) tells you the maximum weight each tire supports at its rated speed; a heavier truck or trailer demands a higher index regardless of ply.
Wheel Diameter and Bolt Pattern
Three 37-inch sizes dominate this category: 37×12.50R17, 37×12.50R20, and 37×13.50R20. The diameter after the “R” must match your wheel, and a mismatch means a new wheel set on top of new tires. Owners switching from 17-inch to 20-inch setups often report improved brake clearance but a stiffer sidewall due to the lower aspect ratio. Confirm your bolt pattern and backspacing before ordering, especially when buying bundled sets that are sized for specific wheel widths.
Mud-Terrain Versus All-Terrain at 37 Inches
A 37-inch mud tire maximizes traction in the worst conditions but sacrifices tread life, fuel economy, and cabin comfort. A 37-inch all-terrain like the AMP or BFGoodrich retains usable highway manners while still offering the clearance advantage of the diameter. The practical rule: if more than half your driving happens on pavement, a high-quality all-terrain in 37 inches is the smarter purchase. If the truck exists primarily for trails and mud pits, commit to the mud terrain and accept the trade-offs.
Our Verdict
The Landspider Rocktraxx M/T four-pack offers the best balance of construction strength, tread capability, and total cost for a dedicated mud-terrain build. For budget buyers who need a single tire or are assembling a set gradually, the ATTURO Trail Blade MTS at $225.07 per tire is the lowest entry point worth considering. If your priorities shift toward daily drivability and you want a 37-inch stance without highway punishment, the BFGoodrich All-Terra T/A KO2 wins decisively on tread life and on-road refinement, provided you can source it at a dealer price that fits your budget.
FAQ
Will 37-inch tires fit my truck without modification?
Almost certainly not. A 37-inch tire typically requires a lift of at least five inches, re-gearing to restore usable axle ratios, and sometimes wheel spacers or custom control arms. Verify clearance against your specific truck model and year before purchasing.
How much does a 37-inch tire affect fuel economy?
Owners consistently report a reduction of three to five miles per gallon compared to a stock tire, driven by the increased rolling resistance, weight, and larger frontal area. The exact penalty depends on your vehicle, driving habits, and whether the tire is a mud or all-terrain compound.
Is a four-tire bundle always cheaper than buying individually?
Not always. Bundled sets can lock you into a brand or tread pattern before you have evaluated how a single tire performs on your specific rig. However, for tires like the Landspider and Atlander options here, the per-unit cost in a bundle is meaningfully lower than the market rate for that specification.
Do I need to re-gear when switching to 37-inch tires?
Yes. A stock gear ratio combined with a 37-inch tire causes the engine to lug at highway speed, reduces towing capacity, and can damage the transmission over time. Most builders pair a 37-inch tire with a 4.88 or 5.13 gear ratio depending on their vehicle and driving goals.
