[QUOTE="LCP, post: 236696, member: 2424"] Err guys, 20, 25, 28, 30, 35 are not in bars, that's psi... If bars that's plenty of exploded tyres as 1 bar is around 14 psi... BMW recommends higher rear pressure than front, presumably to induce a bit more understeer, which is a safer compromise... To reduce understeer you can make the front pressure same as rear... I run 260kPa all round... 225/45/17 all round on my E36. As for FWD cars, there's already default understeer to begin with, so, the front pressure is higher to neutralise the handling a bit... of course this assumes stock standard suspension. [/QUOTE]
