Height will be identical with 225/45/17 and 215/45/17.
The "215" is the width of a tire, also known as the "section width.
The "45"is known as the Aspect Ratio. It is calculated by dividing the section height by the section width and multiplying by 100.
The "17" stands for the diameter of the wheel in inches.

Huh? 225/45-17s are nearly half an inch taller than 215/45-17. The aspect ratio (45 in this case) is the height of the sidewall as a percetage of the width. If you keep the aspect ratio constant, but vary the tread width, you change the height of the tire.

Yeah man, 225/45 will have a larger profile tire. You said your self when talking about the Aspect Ratio. 215 might look better from the side, but from behind the 225 would look better IMO

Correction
215/45/17
Sidewall : 3.82
Radius : 12.32

225/45/17
Sidewall : 3.98in
Radius : 12.48in.

225/45/17 is
0.16 inch higher.

With 215/45/17
Speedometer reading with new tires is .64% too slow.

With 225/45/17
Speedometer reading with new tires is 1.93% too slow.

So does that mean that the 215/45/17 will be closer to the original speedo readings more than the 225/45/17 ??

Sorry for sounding like suck a dummy n00b.

BTW, today I ordered the Rota Attacks in bronze 17xx7.5 +45mm with 215/45/17 Bridgestone Potenza Pole Position s-03 tires.

We're talking tire height, not sidewall height. 215/45-17 is 24.61" and 225/45-17 is 24.97", a difference of 0.36". A 225/45-17 tire is 3.145% too slow and a 215 is 1.656% too slow, compared to a 195/60-15. They're both taller than stock, which is 24.21".

So do you get a "SMOOTHER" ride with the 225/45/17's???

If it rides like a caddy...get it then. Nothing like having a slammed Si, and the comfort.

Is it going to affect cornering though since it has more TOTAL rubber?
