I have talked about 7 differences and similarities between 295/70R18 and 35×12.5R18 tires to help you select the right one for you.

1. Fitment

The diameter of the 295 70R18 tire is 34.26 inches, while the 35×12.5R18’s diameter is 35 inches.

There are only 2% differences in diameter.

The recommended diameter difference when replacing one tire with another is 3%.

Therefore, the 295/70R18 is replaceable with a 35×12.5R18 tire without any modifications.

2. Fuel Economy

Generally, wider tires increase fuel consumption compared to less-thick tires.

The tire width of the 295/70R18 tire is 11.6 inches.

On the other hand, the 35×12.5R18 tire width is 12.52 inches, 7.8% wider than 295 tires.

Therefore, a vehicle with 35 tires consumes slightly more fuel than a vehicle with 295 tires.

It is a cons side of a 35×12.5R18 tire.

If fuel economy is a concern, then the 295/70R18 is better because it provides approximately 1 mpg better fuel efficiency.

3. Ground Clearance

Ground clearance is an important factor for tires, especially for off-roading.

The 295/70R18 tire height is 34.26 inches, and the 35×12.5R18 tire height is 35 inches.

The 35 tire is 0.74 inches taller than the 295 tire.

This is not a significant difference, but it impacts off-road driving.

That’s why the 35×12.5R18 is known as an off-road tire, while the 295/70R18 is known as a light off-road tire.

4. Load Capacity

The maximum load capacity of a 295/70R18 tire is 4,080 pounds.

On the other hand, the 35×12.5R18 tire’s maximum load capacity is 3415 pounds.

The difference does not matter for SUVs, but for pickup trucks, this is a significant difference that matters a lot.

5. Comfort

Tire size or dimension also matters for a comfortable driving experience.

A thicker sidewall tire provides a more comfortable ride compared to a thinner sidewall tire.

The 35×12.5R18 tire’s sidewall height is 8.5 inches, and the 295/70R18 tire’s is 8.1 inches.

The 35×12.5R18 tire is around 4.9% thicker than the 295 70R18.

Therefore, driving a vehicle equipped with 35x 12.5R18 tires is slightly more comfortable than driving a vehicle with 295 70R18 tires.

6. Handling and Stability

Tires with stiffer sidewalls provide better responsiveness and handling capability.

As the 295/70R18 tires are slightly stiffer compared to 35×12.5R18 tires, drivers get slightly better response and stability with 295 tires.

However, the difference is very small and not noticeable in general.

7. Noise and Vibration

A tire’s sidewall height impacts the noise and vibration transmission into the vehicle cabin.

A taller sidewall can absorb more vibration and road-resistant noises.

The 35×12.5R18 tire’s sidewall height is 4.9% taller than the 295/70R18 tire.

The difference is low, so the noise and vibration between the two tires are negligible.


What is a 295 tire equivalent to?

If we want to replace a stock tire with a new one, the new tire’s diameter difference should be within 3% of the stock tire.
