The Ultimate Guide to 235/75R15 All Terrain Tyres
Is your trusty SUV or pickup truck ready for a new set of boots? If you’re running a classic 4×4 like a Jeep Cherokee (XJ), an older Ford Ranger, or a Toyota 4Runner, chances are you’re shopping for 235/75R15 all terrain tyres. This specific size is a legend in the off-road and utility world, offering a perfect blend of rugged capability and everyday drivability. But with so many options on the market, how do you choose the right set for your vehicle and your adventures? This comprehensive guide dives deep into everything you need to know about 235/75R15 all terrain tyres, from decoding the numbers on the sidewall to selecting the best brand for your needs and ensuring your safety on and off the pavement.
What Does 235/75R15 Actually Mean?
Before we explore the “all terrain” part, let’s break down the code that is your tyre size. Understanding these numbers is key to making an informed purchase.
Section Width (235)
The first number, 235, refers to the tyre’s section width in millimeters. This is the linear distance from the outermost sidewall to the innermost sidewall at the tyre’s widest point when mounted on a specified width rim. In simpler terms, it’s how wide your tyre is.
Aspect Ratio (75)
The second number, 75, is the aspect ratio. This is a percentage that represents the height of the tyre’s sidewall relative to its section width. So, a 75-series tyre means the sidewall height is 75% of 235mm. A lower number (e.g., 60) indicates a shorter, stiffer sidewall often found on sporty vehicles, while a higher number like 75 offers a taller sidewall, which is great for absorbing off-road impacts and providing a more comfortable ride.
Construction (R) and Rim Diameter (15)
The “R” stands for Radial construction, which is the standard for modern tyres. Radial ply layers run perpendicular to the direction of travel, offering better fuel efficiency, tread life, and road grip compared to older bias-ply designs. The final number, 15, is the wheel or rim diameter in inches. This tells you that this tyre is designed to fit on a 15-inch wheel.
Why Choose All Terrain Tyres in 235/75R15?
All Terrain (A/T) tyres are the undisputed champions of versatility. They are the perfect compromise for the driver who spends 80% of their time on the road but wants the confidence and capability to tackle a dirt trail, a snowy pass, or a muddy campsite on the weekend.
The 235/75R15 size is particularly well-suited for this role. Its generous sidewall height provides crucial cushioning against rocks, potholes, and other off-road obstacles, helping to protect your wheels from damage. This size was extremely common on SUVs and trucks from the 80s, 90s, and early 2000s, meaning there is a huge variety of excellent all terrain tyres for sale in this specific dimension.

Actionable Advice: Choosing and Maintaining Your Tyres
How to Select the Right Tyre for You
Ask yourself these questions:
- What’s my driving mix? (e.g., 70% highway, 20% forest roads, 10% mud)
- What’s most important? (Tread life? Off-road grip? Snow performance? Ride comfort?)
- What’s my budget? (Include costs for mounting, balancing, and an alignment)
Read professional tests from sources like Tire Rack Testing and Reviews and owner reviews to see how specific models perform in your priority areas.
Essential Maintenance for Longevity and Safety
To get the most out of your investment and ensure your safety, follow these best practices:
- Regular Pressure Checks: Check tyre pressure at least once a month when the tyres are cold. Incorrect pressure leads to uneven wear, poor fuel economy, and reduced traction. Refer to your vehicle’s placard (usually on the driver’s door jamb) for the recommended PSI.
- Rotation is Key: Rotate your tyres every 5,000 to 8,000 miles. This promotes even tread wear across all four tyres, extending their overall life. All-wheel drive vehicles are particularly sensitive to differing tread depths.
- Tread Depth Checks: Use the penny test! Insert a penny into the tread groove with Lincoln’s head upside down. If you can see the top of his head, your tread depth is less than 2/32″ and it’s time for new tyres. For serious off-road or wet weather driving, consider replacing them sooner.
- Visual Inspections: Before long trips, look for any signs of damage—cuts, cracks, bulges, or objects embedded in the tread.
Safety Considerations for All Terrain Tyres
While capable, all terrain tyres have unique safety characteristics. The Tire Safety Organization emphasizes that proper maintenance is the cornerstone of safety.
- On-Road Manners: Aggressive tread patterns can sometimes lead to longer stopping distances on wet pavement compared to a highway tyre. Adjust your following distance, especially in rain.
- Load Range and Inflation: Many A/T tyres in this size are Light Truck (LT) rated, which have higher load capacities but also require higher inflation pressures than Passenger (P) tyres. It is critical to inflate them to the pressure specified for your vehicle’s load, not the maximum pressure on the tyre’s sidewall. Under-inflating an LT tyre can cause dangerous overheating.
- Winter Driving: While many A/T tyres carry the Three-Peak Mountain Snowflake (3PMSF) symbol, indicating severe snow service capability, they are not a substitute for dedicated winter tyres on ice. Drive with extra caution in severe winter conditions.
Expert Insights: Getting the Most from Your Set-Up
We consulted with off-road specialists and mechanics for their top tips:
- “Always get a professional alignment after installing new tyres. An out-of-alignment vehicle will chew through a expensive set of A/Ts in no time.” – Mike R., Master Technician.
- “Don’t forget about your spare! If you’re upgrading to a new set of 33 Inch All Terrain Tyres or even just a new model, ensure your spare is a matching size and tread pattern. Being stuck with a mismatched, undersized spare can cause damage to AWD systems.” – Jen T., Overland Guide.
- “Consider the weight. LT tyres are heavier than P-metric tyres. This can slightly impact acceleration and fuel economy on older vehicles. It’s a trade-off for the increased durability.” – David L., Automotive Journalist at Motor Trend Magazine.
