Tyre Pressure For 18s And Geometry

[Gareth Rose]

Hi guys,

Want to check my tyre pressures on my car but don't know what they should be as the sticker on the door only does 16s and 17s. Ive got the 18 styling kit wheels with PZero Rossos and do mainly motorway driving. What are the recomened pressures?

Also, I wouldn't mind getting my geometry checked,and wouldn't mind visting the 'Dr' but Im down in south wales and can't afford to go all the way up to him, and also havn't got the time. Are there any recommended places in south wales that do it? Im noticing sligthtly more wear on the inners of my fronts than the outers.

Cheers guys

Tyre pressures for the IS are 35psi regardless of size :D

If you know of a geometry place in Wales if you PM Tony im sure he will send you the correct settings for the IS which you can pass on to whoever does your geo.

i had all my tyres changed on my 300 today and the fitter filled the tyres with 40psi in all. is this too much air for the tyres?

the rims are the 18" lexus ones. got pirelli pzero rosso's fitted...very impressed, excellent grip in wet & dry, they corner well too.

..ill take it to local petrol station and change pressure accordingly.
