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 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.
What does 121 118R mean on tires?
90S, 95T, 121/118R, etc. These digits after the tire size, 90S in this example, are the “load index” and “speed rating”. That just means that the maximum pressure on one tire is higher than the other. However, this again is only at maximum pressure which is more than you would usually use.
What does the 65 mean on a tire?
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.
Are 60 or 70 tires wider?
Generally speaking, a 215-60 series tire is wider and has a shorter sidewall then a 215-70 series tire would be and a 215-75 series tire would be taller and narrower then either the 70 series or the 60 series.
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 I put 2 different size tires on my car?
Long story short: Yes, it is a problem to have two tires of different sizes on the front (or back) of your car. Having two different–sized tires on the same axle is generally not a good thing. Sometimes, people choose to put larger tires on the rear axle of their vehicle for handling reasons, cosmetic reasons, etc.
Can I use 215 tires instead of 205?
Nope. The nominal diameter of the 215’s is 1.7% greater than that of the 205’s. The sidewall height is a percentage of the width of the tire, so a 55 series is taller with a wider tire.
What’s the difference between 265 and 285 tires?
The larger 285/70R17 tire in the photo above stands over an inch taller and is nearly an inch wider than the 265/70R17 size. The width of the tread is also a half-inch wider. Many late-model domestic trucks accept this difference in size.
How much wider is a 275 tire than a 265?

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.
Should I get H or T rated tires?
Tires with higher speed ratings generally have better steering response and cornering grip than lower-speed rated tires, in addition to being capable of higher speeds. So if your car originally came with H–rated tires, that’s what you should replace them with. Sticking with H–rated tires comes at a cost.
Is Load Index 121 a 10-ply tire?
Therefore load range simply tells how tough the tire is and the allowable PSI. For example, an “E” load range indicates that a tire is equivalent to a 10–ply construction tire. In realitly, this tire is not built with 10 plies, but rather one or two plies of equivalent strength.
What does 10 PR mean on a tire?
“Q” refers to the tire’s speed rating. In this case, the tire is rated at 99 mph for continuous use. The higher the letter, the faster the tire is rated to travel. 10 PR refers to the ply rating of the tire. A 10-ply rated tire is the same as a Load Range E tire.
