205 or 215's (Bridgestone Potenza PP) on 7.5" wheels (Kosei K1 17x7.5)

Want the extra tread but dont want it to hang over the rim too much.


Wheel size dia width tread width

205/40ZR17 80W (7.5) 7.0-8.0 23.5 8.5 7.5
215/40ZR17 83Y (7.5) 7.0-8.0 23.8 8.7 7.9


Really not too much of a difference in the overall width while the tread width increases at a 2:1 ratio.

What do you all think? :confused:

You can do either one but the 215's will kinda spill over the side a little bit like gravy. :)

Good gravy or bad gravy, because I kinda like gravy.

Anyone have pics or know of a site that will show you what different profiles look like?

Thanks much..

in your case i'd go for 205/40/17.
