forester200 Posted April 19, 2013 Share Posted April 19, 2013 Hi Guys , I'm sure this has been covered many times but couldn't find a definate answer ....I have just got myself some gs300 sport 18's for my TT with new goodyear eagle f1's on and I obviously don't really want to shread the tyres up with wrong pressures , so does anybody know roughly what these should be set at for road use? ...at the mo i have them at 32..... the rears are 275/35/18 fronts 245/40/18 and this info came from the lexus owners club but obviously they are now on my supra so different weight etc cheers Quote Link to comment Share on other sites More sharing options...

Dnk Posted April 21, 2013 Share Posted April 21, 2013 (edited) 33 cold should be fine I'd get a suspension geo done unless its been done recently, doesn't take the toe or camber to be out much before you start trashing your tyres. The camber and toe is adjustable on both front and rear incase you didn't know Edited April 21, 2013 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...

Nemesis Posted April 21, 2013 Share Posted April 21, 2013 Running the same size wheels and tyres at 34 cold all round. Working fine this weekend. Quote Link to comment Share on other sites More sharing options...
Dnk Posted April 21, 2013 Share Posted April 21, 2013 (edited) Page SA-2 of the suspension & axle WSM gives the O/E tyre pressures for both 16" & 17" rims which are both the same, going to 18" makes no difference 33 front & rear, set when cold For some reason i can't post the SA WSM PDF but you might find it on the homepage if you click on repair manuals Edited April 21, 2013 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
