Q45tech always posts that grip is a function of friction coefficients, not necessarily tread width or design.
205 is width in MM40 denotes 40% of 205mm17 is rim diameter
205 x 40% = 82mm sidewall heightx 2 = 164mm + 17"(431.8mm) = 595.8mmconvert from metric to standard (595.8mm / 25.4) = 23.46" tire OD
235 x 45% = 105.75mm sidewall heightx 2 = 211.5mm + 17"(431.8mm) = 643.3mmconvert from metric to standard (643.3mm / 25.4) = 25.33" tire OD
Thanks for the good info. Yes, my 205 rims/tires are form an acura integra

that I bought for my 240. I ran across a pair of 235 for really cheap and was just wondering if that would work at all.
So I'm guessing I'd have to buy rims that are made specifically for that kind of width.
Thanks a bunch. So, anyone want some 235 tires?
