I meant 225 60 15's,sorry, and my quads are KYB's, flippng doesn't matter cause the whole side that would be more narrow is covered. And, for diablo, i use KYB's all around, I'm happy with them, but i'm pretty sure no matter what shocks and struts you have with those springs you'll have a bumpy ride, don't bother me though.

in tire sizes, like 88 said, 275 = width (in millimeters) and 40 is the hight of the sidewall...but it is a percent of the width. So his tires are 275 mm wide, and the side wall of the tire is 40% of that, or 110 mm (11 cm). then if ya wanna go all out, you can calculate overall diameter by multiplying side wall hieght by 2, then convert to inches (I think 2.14 cm =1inch) then add 17 (or whatever the rom size is)so ... 275x.4=110 or 11 cm. 11x2=22 cm. 22/2.14= 10.3 inches + 17=27.3 inches. Or...ya could just look in a tire catalog.
