opinion, I need New RIMS !

[noshun]

the 195/205/215 is the width of the tire in mm the 45/50/55 is the sidewall height (each side of the rim) as a percentage of the width e.g 205/50 the sidewall each side of the tire would be 102.5mm and 205mm in total. I never understood mixing inches and metric on those though and that's the worldwide system! You can work out the rolling circum of each wheel and tire combination and then the difference it will make on the speedo. It wont be as high as 5mp though. But if you plan to mkae a sleeper aren't 17's a little showy? I'm not going over 16" for performance reasons. Probably Enkei or OZ. BTW MSR aren't actually that bad a company for wheels and those have been around for about 4 years now!
