ok guys.. calder drag day is coming.. and im tempted to do a 'pre-engine rebuild quatermile pass' for comparison..

been looking on ebay for some sizeable tyres to fit under the rear of my ute..

im running 195/50/15 tyres on it atm which i know is probably nearly as wide as i can go as it is.. but i dont really wanna fry my good tyres too much so im looking for a pair to slap on for racing fun..

and if im gonna have a spare pair they might aswell be as big as i can get..

so to those who have tried whats the biggest i can get under there without sacraficing paint from my guards?

i know wheel offset is a factor so whats the ideal wheel or offset to use to fit the widest tyres?

thanks in advance
