1. BFGoodrich Mud-Terrain T/A KM3: Best for Extreme Off-Road
In our evaluation of 33-inch tires for 17-inch rims, the BFGoodrich Mud-Terrain T/A KM3 stands out as a top choice for serious off-roaders. Based on the spec sheet, it features a 3-ply sidewall and CoreGard Max technology that resists cuts and chips from sharp rocks. Owner feedback consistently praises its traction in deep mud and loose terrain, making it a reliable companion for trail riding and rock crawling.
However, the KM3 is not for everyone. It produces significant road noise on pavement, and its tread life is shorter than all-terrain alternatives. If you primarily drive on highways or commute daily, this tire may wear prematurely and annoy you with its hum. We recommend it only for those who spend most of their time off-road.
- Mud Terrain with aggressive tread and sidewall armor
- CoreGard Max technology for cut and chip resistance
- Excellent traction in rock, mud, and snow
Pros: Exceptional off-road grip and durability; Strong sidewall protection against punctures
Cons: Noticeably louder on highway than all-terrain tires; Shorter tread life on pavement compared to competitors
2. Goodyear Wrangler DuraTrac: Best All-Rounder
The Goodyear Wrangler DuraTrac is a versatile all-terrain tire that we found to be a strong contender for daily drivers who venture off-road occasionally. According to manufacturer specs, it features Durawall sidewall protection and a tread pattern designed to handle snow, mud, and rocks. Owner reports indicate it wears well on pavement and provides a quiet ride, which is a significant advantage over more aggressive tires.
On the downside, the DuraTrac is not a true mud-terrain tire. In deep mud or loose soil, it can struggle compared to the KM3. Additionally, some owners report uneven wear if the vehicle alignment is not perfect. We suggest this tire for those who want a capable off-road tire without sacrificing daily comfort.
- All-terrain with aggressive shoulder tread
- Durawall technology for sidewall toughness
- Mild snow and mud performance
Pros: Quiet and comfortable on pavement; Good balance of on-road and off-road capability
Cons: Not as capable in deep mud as dedicated mud-terrains; Tread life can be inconsistent depending on alignment
3. Nitto Trail Grappler M/T: Best for Rock Crawling
When we researched the Nitto Trail Grappler M/T, we found it to be a favorite among rock crawlers and serious off-road enthusiasts. The spec sheet highlights a 3-ply sidewall and staggered shoulder lugs that provide outstanding traction on uneven surfaces. Owner feedback confirms its ability to climb over rocks and maintain grip in low-traction conditions.
However, the Trail Grappler is a heavy tire, which can reduce fuel efficiency and acceleration. It also produces noticeable road noise on the highway. If you drive long distances on pavement, this may not be the best choice. We recommend it for those who prioritize off-road traction over on-road comfort.
- Mud-terrain with staggered shoulder lugs
- 3-ply sidewall for puncture resistance
- Excellent traction on rocks and hard surfaces
Pros: Superb grip on rock and technical trails; Durable construction with good sidewall protection
Cons: Heavy and can impact fuel economy; Road noise is moderate to high
4. Cooper Discoverer STT Pro: Best Value Mud-Terrain
The Cooper Discoverer STT Pro offers a compelling value proposition for budget-conscious off-roaders. Based on our comparison of specs, it features Armor-Tek3 construction for enhanced durability and stone ejector ribs to protect the tread. Owner reviews often mention solid performance in mud and on rocks, especially considering its price point.
That said, the STT Pro does not match the on-road manners of more expensive tires. It can be loud and the ride may feel stiffer. Additionally, tread life is average at best. We recommend this tire for those who want a capable mud-terrain without breaking the bank, but be prepared for some compromises in daily driving.
- Mud-terrain with Armor-Tek3 construction
- Stone ejector ribs to prevent stone drilling
- Good off-road traction at a competitive price
Pros: More affordable than many competitors; Durable with good cut resistance
Cons: Tread life is shorter than some all-terrains; Not as refined on pavement
5. Toyo Open Country A/T III: Best Highway All-Terrain
For those who spend most of their time on pavement but want occasional off-road capability, the Toyo Open Country A/T III is a top pick. Manufacturer specifications highlight a silica-reinforced tread compound that improves wet traction and reduces rolling resistance. Owner feedback consistently praises its quiet ride and long tread life, with many reporting even wear over thousands of miles.
However, the A/T III is not a true 33-inch tire; the 285/70R17 measures about 32.7 inches. If you need the exact 33-inch diameter for clearance or aesthetics, consider other options. Also, its off-road traction is limited to light trails and gravel. We recommend this tire for highway-focused drivers who want a durable, comfortable all-terrain.
- All-terrain with silica compound for wet traction
- Tread pattern designed for low noise
- Excellent tread life and even wear
Pros: Very quiet and comfortable on highway; Long tread life with 50,000-mile warranty
Cons: Not as aggressive in mud or deep snow; Slightly smaller diameter than true 33-inch tires
6. Mickey Thompson Baja Boss M/T: Best for Mud and Snow
The Mickey Thompson Baja Boss M/T is a specialized mud-terrain tire that excels in challenging conditions. According to the spec sheet, it features a PowerPly XD sidewall for added strength and a self-cleaning tread that sheds mud easily. Owner reviews often highlight its outstanding performance in deep snow and mud, making it a go-to for winter off-roading.
However, this tire comes at a premium price and is not budget-friendly. It also produces significant road noise, which can be tiresome on long highway trips. If you primarily drive on pavement, you may be better off with a less aggressive tire. We recommend the Baja Boss for dedicated off-roaders who need maximum traction in mud and snow.
- Mud-terrain with PowerPly XD sidewall
- Self-cleaning tread design
- Excellent mud and snow traction
Pros: Great traction in deep mud and snow; Durable sidewall with cut resistance
Cons: Expensive compared to similar tires; Road noise is high on pavement
7. Firestone Destination M/T2: Budget Mud-Terrain Pick
The Firestone Destination M/T2 is an entry-level mud-terrain tire that offers good value for those on a tight budget. Based on our research, it provides adequate traction in mud and on rocks, and the stone block technology helps prevent rocks from lodging in the tread. Owner feedback indicates that it performs reasonably well for light to moderate off-road use.
However, the Destination M/T2 falls short in durability and on-road manners. Tread life is often reported as below average, and the tire can be noisy and harsh on pavement. We recommend this tire only for occasional off-roaders who prioritize cost over comfort and longevity. If you drive off-road frequently or cover many highway miles, consider spending more for a better tire.
- Mud-terrain with aggressive tread pattern
- Stone block technology to reduce stone retention
- Affordable alternative to premium brands
Pros: Low price point for a 33-inch mud-terrain; Decent off-road traction for the money
Cons: Tread life is shorter than competitors; On-road noise and ride comfort are below average
Frequently Asked Questions
Will 33-inch tires fit on 17-inch rims without a lift?
It depends on your vehicle’s make and model. Many trucks and SUVs can accommodate 33-inch tires on 17-inch rims with little to no lift, but you may need to trim the fenders or add a leveling kit. Always check manufacturer specifications and test fit if possible.
What is the difference between load range C and E for 33-inch tires?
Load range indicates the tire’s maximum load capacity and inflation pressure. Load range C typically supports around 2,000 lbs per tire, while load range E supports up to 3,000 lbs. For heavy trucks or towing, load range E is recommended for added safety and durability.
How do I choose between mud-terrain and all-terrain tires for 33s?
Consider your primary driving environment. Mud-terrain tires offer superior off-road traction but are louder and wear faster on pavement. All-terrain tires provide a quieter, more comfortable ride with longer tread life, but they are less capable in deep mud or rock crawling.
What is the actual diameter of a 33-inch tire?
Most 33-inch tires have a nominal diameter of 33 inches, but actual measurements vary. For example, a 33×12.50R17 tire often measures around 32.8 to 33.0 inches when new. Always check the manufacturer’s spec sheet for exact dimensions.
Do 33-inch tires affect fuel economy and speedometer accuracy?
Yes, larger tires increase rolling resistance and weight, which can reduce fuel economy. They also change the effective gear ratio, causing the speedometer to read slower than actual speed. You may need to recalibrate your speedometer or reprogram the ECU.
Our Verdict
After researching and comparing the top 33-inch tires for 17-inch rims, our top pick is the BFGoodrich Mud-Terrain T/A KM3 for its exceptional off-road durability and traction. For a more versatile daily driver, the Goodyear Wrangler DuraTrac is an excellent runner-up that balances on-road comfort with capable off-road performance.
