What Does 235/75R15 Mean?

Every number and letter in a tire size tells you something important. Here is exactly what 235/75R15 means before you buy.

235 is the tire width in millimeters, equal to 9.3 inches across the tread face. 75 is the aspect ratio, the sidewall height is 75% of the tread width, giving this tire a tall, capable sidewall at 6.9 inches. R stands for radial construction, the modern industry standard for strength and ride quality. 15 is the wheel rim diameter in inches.

That taller sidewall is one reason this size is so popular for towing and light off-road use. It absorbs impact well and carries solid load ratings across the board.

235/75R15 Tire Types Available at New American Tires Hub

The right tire depends on how and where you drive. Choosing the wrong category costs you money and performance. Here is what each type delivers and who it is built for.

1 - All Terrain 235/75R15 Tires

All terrain tires are the most versatile option in this size. They handle paved roads, gravel, dirt, and wet surfaces without needing a seasonal swap. Most carry an all-season rating, making them a strong year-round choice for truck and SUV owners across the country.

Look for tread depths between 12/32 and 15/32 for strong off-road bite without sacrificing too much highway comfort. Well-known options in this size include the BFGoodrich All-Terrain T/A KO2 and the General Grabber A/TX, both verified for 235/75R15 fitment.

All terrain tires offer dual-purpose traction, longer tread life than mud terrain tires, and noticeably quieter highway performance. If you spend most of your time on roads but want the confidence to go further, this is your category.

2 - Mud Terrain 235/75R15 Tires

Mud terrain tires are purpose-built for serious off-road use. Large, aggressive tread blocks with wide voids between them dig into mud, loose soil, and rocky terrain — then self-clean on the move so grip stays consistent.

Most 235/75R15 mud terrain options carry a C or D load range rating, making them well-suited for lifted trucks and Jeeps that leave the pavement regularly. Expect more road noise at highway speeds, that is a natural tradeoff for the grip these tires deliver off-road.

Many options in this category feature outlined white lettering (OWL) sidewalls and reinforced construction for added durability under hard use.

3 - Trailer 235/75R15 Tires

Trailer tires are not interchangeable with drive or steer tires. They are engineered to handle sustained vertical load and resist heat buildup during long highway pulls. Installing a passenger or light truck tire on a trailer axle is a serious safety risk.

235/75R15 trailer tires carry the ST (Special Trailer) designation as required by the U.S. Department of Transportation. Load range C and D options support between 1,760 and 2,205 pounds per tire. Before purchasing, match your trailer's GVWR against the combined load capacity of all mounted tires.

New American Tires Hub carries both bias-ply and radial ST options in this size. Radial ST tires run cooler and last longer on sustained highway routes, making them the better choice for most towing applications. Never exceed 65 mph with standard ST trailer tires.

4 - White Wall and White Letter 235/75R15 Tires

White wall tires are back in demand and for good reason. Classic car restorers and muscle truck builders rely on them for an authentic period look that modern tires cannot match. The 235/75R15 size directly replaces original bias-ply size, including 800-15, 820-15, and L78-15 on vintage Cadillacs, Lincolns, and other full-size American vehicles from the 1950s through the 1970s.

White wall options are available in 2.75-inch and 3.125-inch widths for an accurate factory appearance. White letter (OWL) tires suit newer trucks and SUVs wanting a bold sidewall style. The outlined lettering resists cracking and browning with proper tire dressing applied regularly.

New American Tires Hub includes detailed fitment notes per vehicle on white wall and white letter listings, something you will not find at most online tire retailers.

Vehicles That Use 235/75R15 Tires

This size fits a long list of American trucks, SUVs, and classic vehicles.

Common fitments include:

Ford F-150, Chevrolet S-10 Blazer, GMC Jimmy, Jeep Cherokee XJ, Dodge Ram 1500 (select trims), Ford Explorer, Chevrolet C/K 1500, and AM General Hummer.

For classic car applications, the 235/75R15 radial closely matches the original factory bias-ply dimensions used on full-size Cadillac and Lincoln models from 1961 through the early 1970s. It is one of the most dependable crossover sizes for restorers who want a radial tire with period-correct proportions.

Always verify your fitment using the door jamb placard on your specific vehicle. That placard shows the manufacturer-recommended load index and speed rating for your trim and year. Your owner's manual will confirm it as well.

How to Choose the Right 235/75R15 Tire

Buying the right tire takes four straightforward steps. Follow them in order and you will not second-guess your purchase.

Step 1 — Identify your primary use. Daily driving, towing, off-road, or show vehicle use each point to a different tire category. Mud terrain tires are not the right call if most of your miles are on the highway.

Step 2 — Check your load rating requirement. Your door jamb placard shows the minimum load index your vehicle requires. Never go below it. If you tow regularly, move up one load range above the factory spec for added safety margin.

Step 3 — Match the speed rating. Most 235/75R15 passenger and light truck tires carry an S (112 mph) or T (118 mph) speed rating. Trailer tires carry separate ratings and should never be driven above 65 mph under standard conditions.

Step 4 — Set a realistic budget. Tires in this size range from budget-friendly touring options around $90 to premium all-terrain tires near $180. Mid-range tires from established brands typically deliver the strongest value per mile for everyday drivers.

Knowing how 235/75R15 compares to nearby sizes helps you make a confident upgrade or substitution decision.

Size	Diameter	Width	Notes
225/75R15	28.3 in	8.9 in	Narrower, 14.6 more revolutions per mile
235/75R15	28.9 in	9.3 in	Factory size for many trucks and SUVs

265/75R15	30.6 in	10.4 in	Popular off-road upgrade, 1.7 inches taller

Replacement tires should stay within 3% of your original size's overall diameter. Going beyond that range affects your speedometer accuracy, ABS calibration, and fuel economy. The 245/75R15 falls within the 3% window for most vehicles running factory 235/75R15 fitment, making it a common and safe upgrade.

How to Maintain Your 235/75R15 Tires

Proper maintenance extends tread life and protects your investment across every mile.

1- Rotate every 5,000 to 7,500 miles. Consistent rotation prevents uneven wear on drive axles and helps all four tires wear at the same rate. Balance tires at every rotation for smoother high-speed performance and reduced vibration.

2- Inflate to the PSI on your door jamb placard — not the maximum PSI molded into the tire sidewall. Those are two different numbers. Over-inflation causes center tread wear. Under-inflation causes edge wear and dangerous heat buildup at highway speeds.

3- Inspect tread depth monthly. Use the penny test as a baseline: if Lincoln's head is fully visible, you are below 2/32 and the tire must be replaced immediately. Most safety experts recommend replacing at 4/32 for adequate wet traction. Do not wait for the wear bars.

5- Replace all tires after six years regardless of remaining tread depth. Rubber oxidizes and loses flexibility over time, and age-related cracking is a blowout risk even on low-mileage tires. Check the DOT date code on the sidewall to confirm manufacture date.

Frequently Asked Questions About 235/75R15 Tires

What vehicles use 235/75R15 tires?

Common fitments include the Ford F-150, Chevrolet S-10 Blazer, GMC Jimmy, Jeep Cherokee XJ, Dodge Ram 1500 (select trims), Ford Explorer, and Chevrolet C/K 1500. Classic full-size Cadillac and Lincoln models from the 1950s through early 1970s also use this size as a direct replacement for original bias-ply fitments. Always confirm using your door jamb placard before purchasing.

What are the dimensions of a 235/75R15 tire in inches?

A 235/75R15 tire measures 28.9 inches in overall diameter and 9.3 inches in section width. The sidewall stands 6.9 inches tall. It fits a 15-inch rim and completes 699 revolutions per mile.

What is the difference between 235/75R15 all terrain and mud terrain tires?

All terrain tires balance on-road comfort with off-road grip and work year-round on pavement, gravel, and dirt. Mud terrain tires carry larger and more aggressive tread blocks built specifically for mud, loose rock, and technical off-road surfaces. Mud terrain tires produce more road noise and wear faster under regular highway use — they are purpose-built tools, not daily drivers.

Can I use 235/75R15 tires on a trailer?

Yes, but only with ST (Special Trailer) rated tires. Passenger and LT tires should never be installed on a trailer axle. ST tires are engineered to handle sustained vertical loads and resist heat buildup during long towing runs. As required by the U.S. Department of Transportation, standard 235/75R15 ST trailer tires carry a 65 mph maximum speed rating.

What classic car bias-ply sizes does 235/75R15 replace?

The 235/75R15 radial replaces bias-ply sizes 800-15, 820-15, and L78-15. It fits classic Cadillacs, Lincolns, and full-size American cars from 1961 through the early 1970s. White wall options are available in 2.75-inch and 3.125-inch widths for an authentic factory appearance.

How long do 235/75R15 tires last?

Tread life ranges from 30,000 to over 80,000 miles depending on tire category, driving habits, and maintenance. All-season touring tires with high UTQG treadwear ratings typically last longest. Regardless of remaining tread, all tires should be replaced after six years. Rubber compounds degrade with age even on low-mileage sets.

Is 235/75R15 the same as 235/75-15?

Yes. Both notations describe the identical tire. The R in 235/75R15 confirms radial construction. Older catalogs and some aftermarket guides drop the R, but the fitment and dimensions are exactly the same either way.
