Understanding 35-Inch Tire Sizes
Before we dive into the equivalents, let us understand what a 35 inch tire actually is. The number 35 refers to the overall tire diameter in inches. This measurement goes from one edge of the tire to the other, passing through the center of the wheel.
Tire sizes are written in two main systems. The first is the standard or imperial system, which looks like 35×12.50R17. The second is the metric system, which looks like 315/70R17. Both systems describe the same tire in different ways.
Here is a quick breakdown of what each number means in the standard system:
- 35 = overall tire diameter in inches
- 12.50 = tire width in inches
- R = radial construction (the most common type today)
- 17 = wheel rim diameter in inches
In the metric system, the first number (315) is the tire width in millimeters. The second number (70) is the aspect ratio, which is the sidewall height as a percentage of the width. The R means radial, and the last number (17) is the rim diameter.
Why the Number 35 Matters
The 35 inch size has become a popular choice for off road enthusiasts and truck owners. It offers a great balance between ground clearance, traction, and daily drivability. Many people choose 35 inch off road tires because they can handle rocks, mud, and rough terrain better than smaller sizes.
But here is the thing. Not every tire labeled as 35 inches measures exactly 35 inches. Tire manufacturers sometimes size tires a little differently. This is why it is important to check the actual tire rolling diameter before you buy. A tire that is listed as 35 inches might actually measure 34.5 or 35.3 inches in real life.
Common Equivalent Tire Sizes for 35s
Now let us get to the heart of the question. What is the equivalent to 35 in tires? Several sizes are considered equivalent, and they fall into two main categories: standard sizes and metric sizes.
Standard Equivalent Sizes
The standard sizes use the imperial measurement system. Here are the most common ones:
- 35×12.50R17 – This is one of the most popular 35 inch tire sizes. It fits a 17 inch wheel and is about 12.5 inches wide.
- 35×12.50R18 – Same diameter, but fits an 18 inch wheel. Very common on newer trucks and SUVs.
- 35×12.50R20 – Fits a 20 inch wheel. This size is popular on modern full size trucks.
- 35×13.50R15 – A wider tire that fits a 15 inch wheel. Often used on older trucks and Jeeps.
Metric Equivalent Sizes
Metric sizes are used widely around the world and on many factory stock vehicles. Here are the metric equivalents to 35 inch tires:
- 315/70R17 – The most common metric equivalent. It measures very close to 35 inches in diameter.
- 315/70R18 – Same width and aspect ratio, but fits an 18 inch rim.
- 315/70R20 – Fits a 20 inch wheel. Very popular for modern trucks.
- 325/65R20 – A slightly different aspect ratio but still close to 35 inches.
- 285/75R16 – This one measures closer to 33 inches, so it is not a true 35 inch equivalent. Always double check the diameter.

As you can see from the table, there are many ways to get a 35 inch tire on your vehicle. The key is matching the right size to your wheel diameter and your vehicle’s clearance.
How to Find Your Tire Size Equivalent
Finding the right equivalent for your 35 inch tire is not hard, but it does require a few simple steps. Here is how to do it.
- Check your current tire size. Look at the sidewall of your existing tire. You will see a string of numbers like 315/70R17 or 35×12.50R17.
- Measure the overall diameter. Use a tape measure from the ground to the top of the tire. This gives you the real diameter, not just the listed size.
- Use a tire size calculator. Many websites offer free tools where you enter your current size and get a list of equivalent sizes.
- Consider your wheel width. A tire that is 12.5 inches wide needs a rim that is between 8 and 10 inches wide. Putting a wide tire on a narrow rim can cause handling problems.
- Check your vehicle clearance. Make sure your lift kit and fender clearance can handle the new tire size.
Quick Tip: Always Verify the Actual Diameter
Do not trust the listed size alone. Two tires both labeled as 35 inches can differ by half an inch or more. Always measure or use a trusted tire size chart to confirm the actual diameter before you buy.
Why Tire Size Equivalency Matters for Your Vehicle
You might be thinking, why does it matter what size equivalent I choose? The answer is that tire size affects more than just how your truck looks. It impacts how your vehicle drives, handles, and performs.
Speedometer Accuracy
When you change your tire size, your speedometer can become inaccurate. If you put on a tire with a larger diameter than stock, your speedometer will read slower than your actual speed. This can lead to speeding tickets or, worse, unsafe driving situations. Most 35 inch tires are close enough to stock sizes that the error is within an acceptable range, but it is still worth checking.
Gear Ratio and Drivetrain Stress
Larger tires are heavier and have more rolling resistance. This means your engine has to work harder to turn them. If your vehicle has a gear ratio that is not suited for 35 inch tires, you may notice poor fuel economy, overheating, or strain on your drivetrain. Many off road enthusiasts regear their differentials when they go up to 35 inch tires.
Wheel Offset and Clearance
The wheel offset determines how far the wheel sits in or out from the fender. A proper offset is essential when running 35 inch tires. Too much offset can cause the tire to rub on the fender or suspension components. Always check your vehicle’s specifications before choosing a wheel and tire combo.
Popular 35-Inch Tire Models You Should Know
Not all 35 inch tires are created equal. Different brands and models are designed for different types of driving. Here are some of the most popular 35 inch tire models on the market right now.
Best for Off Road Performance
If you hit the trails hard, you need a tire that can handle rocks, mud, and loose terrain. The BFGoodrich KO2 in 35×12.50R17 is a top pick among off road enthusiasts. It offers excellent puncture resistance and grip in rough conditions. Another great option is the Mickey Thompson Baja MTZ, which is known for its aggressive tread pattern and strong sidewalls.
Best for All Terrain Use
If you want a tire that works both on and off the road, consider all terrain tires in 35 inch size. The Goodyear Wrangler DuraTrac is a popular choice. It provides a quiet ride on pavement while still offering solid off road traction. The General Tire Grabber A/TX is another excellent option that balances highway comfort with trail capability.
Best for Mud Terrain
For serious mud bogging, nothing beats a dedicated mud terrain tire. The BFGoodrich KM3 in 35×12.50R17 is one of the best mud tires available. It self-cleans its tread blocks and provides outstanding grip in deep mud. The Falken Wildpeak M/T is another strong contender that offers great value.
Common Mistakes When Choosing 35-Inch Tires
Making the wrong choice when buying 35 inch tires can cost you money and cause headaches. Here are some common mistakes to avoid.
Ignoring the Wheel Width
One of the biggest mistakes people make is choosing a tire without considering the wheel width. A 35×12.50 tire needs a rim that is the right width. Too narrow or too wide, and the tire will not seat properly or will wear unevenly.
Forgetting About the Lift Kit
35 inch tires are big. They require serious lift kit clearance to fit properly. Many people buy the tires first and then realize they need a lift. Always plan your build in advance. Check your suspension travel and fender clearance before ordering.
Not Checking the Load Rating
Not all 35 inch tires are rated for the same weight. If you have a heavy truck or carry lots of cargo, you need a tire with a high load rating. Look for LT (Light Truck) rated tires for the best durability and safety.
Skipping Speedometer Recalibration
After installing 35 inch tires, your speedometer may read a few miles per hour off. This is not just an inconvenience. It can also affect your cruise control and your vehicle’s computer systems. Many people choose to get their speedometer recalibrated after a tire change.
Choosing the Wrong Tread Pattern
Not all tread patterns are right for every situation. A mud terrain tire will be noisy on the highway. An all terrain tire might not grip well in deep mud. Think about where and how you will drive most often, and choose your tread pattern accordingly.
Expert Insights: Getting the Most Out of Your 35-Inch Tires
After years of working with truck and SUV builds, here are a few tips that can help you get the best results from your 35 inch tires.
First, always invest in a quality tire pressure monitoring system. Larger tires can lose pressure slowly, and low pressure leads to poor fuel economy and uneven wear. A TPMS helps you catch problems early.
Second, rotate your tires regularly. 35 inch tires are expensive, and you want them to wear evenly so they last as long as possible. A rotation every 5,000 to 6,000 miles is a good rule of thumb.
Third, consider your speedometer calibration before you hit the road. A simple calibration device or a trip to your dealer can keep your speed readings accurate. This is especially important if you use cruise control frequently or drive in areas with strict speed limits.
Finally, do not overlook the importance of proper torque specs on your lug nuts. Larger tires put more stress on your wheels. Make sure every lug nut is tightened to the manufacturer’s recommended torque every time you change a tire or rotate.
