jevansio Posted February 19, 2009 Share Posted February 19, 2009 I was looking into what size tyres I need for some 18" rims today, and was working out the stock rolling radius compared to what I have on at the minute. I run 295/30/19's on the back (purely because it's the only R888 size available), and when I worked out I got the rolling radius was 3.75% bigger than stock. What sort of effect does this have on acceleration when pulling speeds of say 180mph? Quote Link to comment Share on other sites More sharing options...
JamieP Posted February 19, 2009 Share Posted February 19, 2009 Id say our cars have similar power and mine pulls them speeds no problem with the same size tyre. It did pretty well at Suprapod aswell so id say it wont be detrimental to acceleration either. Quote Link to comment Share on other sites More sharing options...

Cheers bud, I figured I'd try & get closer when I pick my 18" tyres, 275/35/18 seems to be the best I can find, hoping the 18's will improve my launch Quote Link to comment Share on other sites More sharing options...

I was tossing up between the 275/35 & 285/30, I figured I'd go with the extra side wall, let me know what you think of them, I still have to bolt 4 wheels together before I can think about getting tyres Quote Link to comment Share on other sites More sharing options...
