235 vs 245 Tire Width: Difference Between 235 And 245 Tires

While some people may think that all tires are the same, there is a vast difference between them. The numbers on the sidewall actually mean something, and those numbers help you find the right tires for your vehicle so it can perform better and be safer.

The biggest difference between the 235 and 245 tires will be the 10-millimeter width. The wider 245 will have more stability and better handling than the 235 tires. However, the 235 tires will get better gas mileage which is always a good thing.

To learn more about these two tire models, just continue to read our article. It delves into the topic so you get the best information possible. This information should help you make a better purchase decision.

Difference Between 235 And 245 Tires


As you know, there is about a 3/8 of an inch difference between these two tires. The 245 is a little wider and taller than the 235 and may require a minimum of an 8-inch rim. The 235’s minimum rim width is 7.5 inches.

This little difference means that the 245 is going to be heavier than the 235 but it will also provide you with more stability, control, and traction. More rubber on the road equals better traction.

This extra width also means that the 245 tire has more rolling resistance. That equates to a lower mpg than what the 235 will get. But in some cases, and despite the extra fuel efficiency, the 235 is not the best tire for every car, truck, or SUV model.

235 vs 245 Tire Width


As you can see by the chart and the numbers, the 245 tire is slightly wider than the 235 tire. This does make a difference in different aspects of driving. The wider tire will always be heavier and it will always have more rolling resistance.

But the benefits that come with the wider tire may offset those negatives. With better stability and handling, you can navigate slippery roads better and safer. That should give you a little peace of mind.

235 vs 245 Winter Tires

One of the advantages of using 245 winter tires over their 235 competitors is that you have a stronger tire on your rims. This is handy when your car slides a little and hits a curb. You may not see any damage done to your wheels or tires if you have 245 tires on your vehicle.

Plus, you should have better traction on those snowy and wet roads. Of course, you will pay more for the 245 tires but that is because there is more rubber involved in its construction.

You should still have better performance results with the larger tire than with the smaller one. It all depends on what you want out of your tires. There are a lot of good points for the 235 that make them worth considering.

235 vs 245 Tire Noise


The wider tire will make more noise than the thinner tire. That means that the 245 tire will be noisier than the 235 tire. But with the way they build the passenger compartments in modern vehicles, will noise really be a major factor?

The narrower tire will have less air hitting it. The smaller tire surface will always be quieter than the wider surface. This is going to be up to you and what you prefer. You may not hear much difference between the two tires and may not notice tire noise when you drive.

Can I Replace 235 Tires With 245?

As long as the 245 tire can fit the rim of the 235 tire, then there should not be any problem. The differences between these two tire models are slight making them interchangeable for the most part.

The fuel efficiency, while greater in the 235, is not that much different. You may lose about 1/2 to 1 mpg when you upgrade to a 245 tire but that is not set in stone. When you want a stronger tire, then upgrade to the 245.

235/55R19 vs 245/45R19


When you get a tire with a larger aspect ratio, then you are going to get a bigger tire. In this case, the 235 is taller than the 245 by 1 1/2 inches- 27.68 to 29.18 (the latter figure is for the 235).

The width will not change as the 245 will always be wider than the 235 no matter its aspect ratio. Then the circumference and sidewall height will be larger in the 235 tire.

The biggest problem you will have if you switch the 245s for the 235s, in this case, is that your speedometer reading maybe 3 miles faster than your actual speed. That is great for radar traps but maybe not for highway driving.

Some Final Words

When it comes to tires, you want the best for your vehicle. Depending on your vehicle and purpose sometimes the 235 tire is best and sometimes the 245 is best. If you do a lot of off-road driving, then you will want the 245 tire.

But if you are mostly on paved roads, then the 235 is better. Also, the tire you select will depend on the amount of weight you are hauling or towing. The 245 is stronger and handles more weight.
