What do the 3 numbers mean on tire size?
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. It’s the height of the sidewall measured from wheel rim to top of the tread, expressed as a percentage of tire width. In other words, it’s sidewall height divided by tire width.
What does the 265 70r17 mean?
This number indicates that your tire has a width of 265 millimeters. 70. This number means that your tire has an aspect ratio of 70%. In other words, your tire’s sidewall height (from the edge of the rim to the tire’s tread) is 70% of the width. In this case, the sidewall height works out to be 185 millimeters.
Can I use 60 instead of 65 tires?
Physically, yes they will fit. It is recommended to stay within 3% of the original tire size on the car though. The size you have is 3.09% smaller, so not recommended. You could go with 205/60-15 though if you can get a better deal on that size.
What does 225/45 mean on a tire?
The number “225” stands for the width of the tire in millimeters – so in this case the tire is 22.5 cm wide. The “45” that follows is the aspect ratio – the height of the tire sidewall as a percentage of its width.
Can I use 235 tires instead of 225?
Yesthat size will work 100% perfectly, as it is the exact same diameter as the 225/75-16. 235/70-16 is actually a shorter tire.
Can you put different width tires on same rim?
To keep the suspension and speedometer functioning correctly, both the stock diameter and width of the wheels and tires needs to be maintained. As a general rule of thumb, it’s safe to fit a tire up to 20 millimeters wider than stock on the original rim.

From a safety point of view, both types have their good sides: On a dry road, wider tires will offer more grip than narrow ones, but the risk of aquaplaning will be higher with wide tires. – In the winter, narrow tires are better under extreme conditions as they provide higher surface pressure against the road.
Does changing tire size affect transmission?
Changing tire size doesn’t affect your transmission, but it does change your final drive ratio. The effect is the same as if you had changed your transmission. Larger tires will lower your final drive ratio. (as if all your gears were “higher”) Your car will go further with each revolution of the tire.
