What Do The Numbers Mean On Tires Sizes

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 does the 265 70R17 mean?

How to read your tire size long description. 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.

Can you use 235 tires instead of 225?

Can 225 fit 235 tires? Yes, they can. 225 tires are 10 mm narrower and 15 mm lower in height than the 235 tires. Besides, 235 tires are wider than 225, and so we recommend checking the owner’s manual.

What does 50r mean on tires?

50 is the two-figure aspect ratio. This percentage compares the tire’s section height with the tire’s section width. For example, this aspect ratio of 50 means that the tire’s section height is 50% of the tire’s section width. R indicates the construction used within the tires casing. R stands for radial construction.

What is the difference between a 60 and 65 series tire?

The 65% aspect ratio (as in 235/65/17), compared to 60%, adds almost 12 mm (1/2″) to the radius of the tire (0.65-0.60)*(235mm)=11.75mm.

Should I change all 4 tires?

It’s always best to replace all 4 tires at the same time. This is because all 4 tires spin independently of one another, and different tread depths and/or styles can cause them to spin at different speeds. That could potentially damage the drive train, and possibly affect an indirect TPMS system if the vehicle has one.

Do wider tires handle better?

2. Improved Cornering. The same aspect of having a wider contact area with the road with the above, wider tires offer better cornering and road handling. It is also because wider tires have a better thread and stiffer sidewalls that they have less vehicle roll in corners.

What does P245 mean on a tire?

For example a LT265/75R16 would be around 31.6 inches tall and 10 inches wide. “LT” means Light Truck and “P” means Passenger tire. The bigger number (on the left) is the Section Width.

What does 70 mean on a tire?

If a tire has an aspect ratio of 70, it means the tire’s height is 70% of its width. Lower aspect ratio tires, such as a 60 series, generally offer vehicle handling performance advantages over higher aspect ratio tires, such as a 75 series, but a typical trade off can be ride harshness. Construction.
