I ordered an aftermarket set of wheels by size 17x8 which is an inch wider than stock 17x7. I still was going for 215/45/17 tire size which is the OEM tire size but 225/45/17 size is still an option for me.

Tire sales person told me that both size are perfectly fine for 17x8 and Looks & performance are very similar. Anyone can think of advantage/disadvantage of me sticking with 215/45 other than it is cheaper?

A 225/45-17 will be slightly taller. Your speedo will be slightly off but not by so much that you should worry about it. Plus they will fill the wheelwell better. If you have lowered the car, check to see if they rub. Lastly, they will probably weight about 2 pounds more each.

So which one would you suggest? Sounds like I'll do fine with 215.. I was going to go 225 if they worth the money but.. and No, I did not lower my car. With my ground kit, my car is already pretty low.

l would go with 225.Wider tire means better grip but one centimeter isn't that much of a difference.
225 would also look better IMHO.lt's up to you.

not to bring an old thread back from the dead but, 225/45/17 is not taller its wider

225 = width
45 = height
17 = rim size

ready to get pwned? lol

Stock is 215/45/17 so the height of stock rubber is 215*0.45 = 96.75mm
other is 225/45/17 so the height of them is 225*0.45= 101.25mm

So they ARE taller but not by much.

Thanks Spitzer.

To 96tib:
That's why I said "slightly taller". The sidewall is 4.5mm taller which makes the overall tire height 9mm taller.

215/45-17 = 24.6" tall and 77.3" in circumference
225/45-17 = 25.0" tall and 78.5" in circumference

That is an error of 1.4%. The speedo will read 60-mph but you will actually be traveling 60.9-mph. That doesn't seem like much, and it isn't, but it's a good rule of thumb to have speedometer error under 1%.

on a tire that is 215/45/17 the second number (45) is the aspect ratio so the sidewall is 45% as tall as the tire is wide so 45% of 215 is 96.75mm thats how tall the sidewall is all around. so on a tire that is 225/45/17 then the sidewalls would be 45% of 225 or 101.25mm tall all the way around. the same thing applies to wider tires

from a looks point of view, seeing how the rims are 8 inchers wide i would go with the 225 for 2 reasons

1 since the 225 will be wider the wheel itself will look more flush or even recesed within the tire then the 215 so IMO it looks better
2 since the 225 will be wider the wheel itself will be better protected from curbrash since the tire is more likely to scape the curb before the rims does

l didn't know that,l mean l've never been thinking about it.lf 215,225,235 are all 45 high 235 is considerably higher than 215.

As for you troyboy162 l would go with 225/40R18 l have the exact size rims.But there isn't realy much meat for potholes.If you go higher,like 45 your speedo will lie to much.
