When it comes to your vehicle’s tires, making the right choice is crucial for optimal performance, safety, and efficiency. One common question that arises among vehicle owners is:
Can I Replace 235 Tires with 245? Yes, you can switch out your 235 tires for 245 tires. But there are a few things to think about: Upgrading from 235 to 245 tires will result in a 0.5 mph change in speed. 235 tires have a little lower weight carrying ability than 245 tires, so upgrading to larger tires will boost this capacity. The 245 tire is 0.3 inches wider than the 235 tire. In comparison to the 235 tire, this could cause the tire to protrude slightly over the rim.
It’s crucial to remember that, for safety purposes, if only two tires need to be replaced, they should go on the back axle. Additionally, it is advised to speak with a qualified mechanic or tire expert if you are unclear about whether you should change your tires or what size to use.

Understanding Tire Sizes: The Basics
What Do the Numbers Mean?
Tire sizes consist of a series of numbers, such as 235/65R18. The first number, in this case, 235, represents the tire’s width in millimeters. The second number, 65, indicates the aspect ratio or the tire’s height as a percentage of its width. The “R” stands for radial construction, and the final number, 18, indicates the diameter of the wheel in inches.
The Impact of Tire Size Differences
Changing tire sizes, such as replacing 235 tires with 245, can have various effects on your vehicle. A wider tire, like a 245, may provide better traction due to the increased contact area with the road.
