Difference Between 35 And 37 Tires : [ 2022 Comparison ]

Difference Between 35 And 37 Tires : [ 2022 Comparison ]

As you go shopping for new tires, you may notice some tire sizes are more significant than others. The differences between 35-inch and 37-inch tires can be confusing, so you are not alone if you are unsure which size you need.

Tire size should be one of your first considerations when buying a car, truck, minivan, or SUV. Knowing this will help you choose the right size, significantly improving your car’s fuel economy.

Main Difference Between 35-inch and 37-inch tires

35-inch tires are typically used for daily driving, having a better fuel economy. They are also more comfortable on the road and have better ride quality.

37-inch tires, on the other hand, are typically used for off-road capabilities. They have higher ground clearance, and bigger tires make your car look better.

35-inch vs. 36-inch Compared

SUV tires are commonly available in two sizes: 35-inches and 36-inches. Despite having different names, both tire sizes are the same width (11.3 inches).

The Difference comes from the diameter of the wheel. 35-inch tires have wheels that are approximately 22.5 inches in diameter. 36-inch tires have wheels that are about 24 inches in diameter.

The width of the tires or rims on your vehicle is not the deciding factor for which tire size to choose; you need to look at the wheel diameter. The wheel diameter will likely be on the manufacturer sticker on your SUV’s door frame.

1. Appearance

37″ tires are high-performance tires and are made for high-power cars, but at the same time, a person who loves to drive aggressively or wants to have a grip on the off-road can buy 37″ tires.

These tires are usually combined with low-profile rims and are installed in the car’s rear. 35- inch tires are for softer and simpler use on your vehicle; they are most detonated with a relaxed view on the road.

2. Ground Clearance

It affects whether you can go off-road or not. Ground clearance is measured in inches, and it describes how tall the bottom of the vehicle is above the ground.

This is a crucial measurement for off-roading. For example, higher ground clearance is needed for driving on rocky, muddy, or uneven roads.

If there is not enough clearance, the bottom of the vehicle could get damaged. The higher the ground clearance, the more influential the engine and the larger the wheels.

For off-roading, higher ground clearance is needed; 37-inch tires will give you a higher ground clearance compared to 35-inch tires.

3. Terrain vs. Off-Road

In plain English, off-road tires are made to provide traction in difficult driving conditions such as mud, while terrain tires are made to provide a comfortable on-road ride.

Off-road tires are a compromise. They perform well in mud but tend to be noisy and don’t ride as well on the highway.

Terrain tires have a small off-road footprint but are designed for a smooth ride. They’re quiet, but their lack of off-road traction will leave you stuck in deep mud.

The bigger the tire, the better it will handle off-road challenges.

4. Daily Usage

While there is no set rule for why 37-inch tires are used over 35-inch, there are a few theories. The first is that 35-inch tires are typically used on more powerful vehicles with better traction.

A 37-inch tire provides more traction while sacrificing the speed of the car.

Another theory is that 35-inch tires are typically used on larger vehicles because they provide a smoother, more precise ride.

Bigger tires will not offer the advantages they bare when used daily, unlike the standard SUV 35-inch tires, which are more applicable for daily use around smooth terrains.

5. Suspension

A suspension lift is generally considered a part of the suspension system. A suspension lift is a modification to the suspension of a motor vehicle.

This can be done for several reasons, to improve the ground clearance of a car for off-road driving and to raise the car for aesthetic reasons. A suspension lift will generally increase the vehicle by 2-6 inches.

A suspension lift can be done in conjunction with a lift kit.

37-inch tires will generally need a suspension lift to be accommodated by standard cars. On the other hand, the 35-inch tire can be added without the worry of having your tire scrub the body or the fends.

6. Fuel Economy

This is a significant difference between 35-inch and 37-inch tires on a car. A 35-inch tire on a vehicle has a rolling resistance of about 22% less than a 37-inch tire on the exact vehicle.

The result is a better mpg rating and better fuel economy. A 35-inch tire has a lower rotational mass and will provide better acceleration and braking capabilities.

The Difference between a 37-inch tire and a 35-inch tire on the same vehicle would be one mpg.

7. Cost

The cost of 35-inch and 37-inch tires is a significant difference in car tires. A 35-inch tire costs $40 less per tire than a 37-inch tire.

This is because the 35-inch tires are less technologically advanced than the 37-inch tires. The 35-inches tires are also not as big as the 37-inch tires.

The larger the tire, the more expensive it is to buy, maintain and keep up. Although you won’t have to replace it as often, a change in the size of the tires may change the way you drive.

8. Towing Capacity

Towing capacity is the Key Difference between 35-inch and 37-inch tires. It is the deciding factor between buying a 35-inch or a 37-inch tire, especially if you think of towing your vehicle.

Towing capacity was the most important reason for me choosing the 37-inch tires. 35-inch tires are rated for 2,000 pounds, and 37-inch tires are rated for 2,700 pounds.


What do I Need to Run 37-inch tires?

37″ tires are legal for some classes of vehicles. The physics and tire construction laws would make it impossible to run 37-inch tires on stock rims with stock suspension and remain street legal.

Approximately 5 inches more tread depth is needed for the tires to be legal to run 37-inch tires.

35-inch tires on a 2-inch lift?

Yes, you technically can fit 35″ tires on a 2″ lift. They are only supposed to fit on 35″ rims, so you need to make sure those rims are on.

The problem is that the 35″ tires will hit the fender flares, and you’ll look like an idiot. Aftermarket 2″ lift kits allow you to use 35″ tires on your Jeep, but the suspension will be about an inch and a half higher than stock.

PSI for my 35-inch tires

The short answer would be around 50-55 PSI for a 35-inch tire. The tires on your car are your primary link to the road, and you should take care of what you put on your vehicle.

When a tire is inflated at 50-degree temperature, the tire walls are firm, thus enabling the tire to support weight better. At 80-degree temperature, the tire walls are softer; therefore, the tire walls will sink into the ground, and the tire will give in.

37-inch Tires on a Stock Jeep Wrangler

Despite being the most popular tire size, the 37-inch-tall tire size is not very common. Most of us don’t know much about tires, wondering; can you run 37s on a stock Jeep Wrangler?

The answer to that question is a definitive “yes,” but that answer doesn’t give the critical stuff contained within. However, you’ll need to upgrade your axles and springs.

Without getting too technical, the extra 1/4-inch width on the 37-inch tire equates to 5 inches more contact patch, so a 37-inch tire will grip the road better in lower-grip situations but won’t necessarily give you more cornering grip in higher-grip conditions.


The differences between the two tires are that the 37-inch tires are slightly wider, and the tires are somewhat heavier. 37-inch tires provide more tires on the road.

Compared to the 35-inch wheel, the 37-inch tire is 0.4 inches wider. In that manner, a 37-inch tire travels on the road with 2.8 inches more tire.

That works as an advantage as a 37-inch tire has 88% more tires on the road.
