This number is the Aspect Ratio of the tire and represents the percentage of sidewall in respect to the width of the tire. For example, on a 175/70R14, the treadwidth is 175mm and the sidewall would be 70% of that or 122.5mm. The R simply means Radial and the 14 tells you the rim size (14").
The lower the Aspect Ratio, the closer to the rim is the tread. When turning, there is less sidewall to bend which yields a quicker, more responsive tire. That's why most performance tires have a lower aspect ratio. In higher speed rating tires, you will find the sidewalls are reinforced which gives even better performance.
That smaller sidewall does have it's drawbacks though... you will feel more of the road imperfections as you have less material insulating you from them. Pot holes cause problems as the tire has less room to move before hitting the rim etc.
Good luck!

Are you talking about the designation after the tire width?
Example: 175/80R versus 185/70R
First the "R" just means a Radial tire (type of construction).
The number is the percentage of the width that the sidewall is high.
175*0.80 = 140 That means your tire is 175 mm wide and the tread will be 140 mm from the wheel rim.

like a 185-70-14 and a 185 -80-14 the 185 is the with of the tire 70 is 70% of the with is the hight of the tire from the rim to tread 14 is the rim size so on the 80 the hight of the tire is a little bigger about a 1/4 inch i hope this helps you

This number is the width of the tire. Stick with whatever is suggested. If you get something too wide, you'll have problems. Besides, only one size should fit on your wheels.

Sidewall height. The lower the number, the smaller the tires sidewall. Smaller is better.
