B: TIRE WIDTH The three-digit number following the letter is the tire’s width (from side to side, looking at the tire head on) in millimeters. This may also be referred to as the section width. C: ASPECT RATIO The forward slash separates the tire width number from the two-digit aspect ratio.

What does the 265 70R17 mean?

An arrow points to the numbers 265/70R17 115T on the inner part of the tire sidewall. 265 is the width, 70 is the aspect ratio, R stands for radial, 17 is the wheel diameter and 115T is the load index and speed symbol. ©2021 Nitto Tire U.S.A. Inc.

Can I use 235 tires instead of 225?

Because they have less life, the tires of the vehicle need to be regularly maintained and replaced. When we practically consider these two tires, both are durable enough to handle their respective types of vehicles. In some cases, both 225 and 235 tires are compatible with the same car.

Which tire is wider 245 or 265?

Is a 70 or 75 tire wider?

The sidewall of a 70-series tire will be 70% of the width, a 75 series will be 75% of the width. If you want the same HEIGHT in a 70 series, then you need to go wider in the width — about 219.

Which tire is wider 50 or 60?

For example, a 60-series tire features a sidewall that is 60% as tall as the tire’s section width. A 50-series tire will feature a shorter sidewall, at 50% of section width.

Which tire is wider a 40 or 45?

So on a set of tires that are 215mm wide, a /40 profile tire would have an 86mm tall sidewall, and a /45 profile tire would have a 96.75mm sidewall. So that’s about a quarter inch of difference between the two, which as stated isn’t going to be very visible.

The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P215/65 R15 tire, the 65 means that the height is equal to 65% of the tire’s width. The bigger the aspect ratio, the bigger the tire’s sidewall will be.

What is the 45 in tire size?

45 (Aspect Ratio): The tire’s sidewall is 45% of the tire’s width, which means the sidewall is about 114 millimeters or just over 4 inches. R (Construction Type): Radial tire, the most common type of tire produced today. 18 (Wheel Size/Rim Diameter): Going from edge to edge, the tire’s diameter is 18 inches across.
