Tyre Pressures???

Kam187 · 02-26-2014, 11:05 AM

I've just purchased a 335i M Sport Saloon.

The car is sitting on standard suspension but has 19" BBS CH Wheels with spacers running the following tyre sizes which are not standard so BMW data is pointless.

Tyres: Michelin Pilot Super Sports

Front: 235/35/ZR19 91Y

Rears: 275/30/ZR19 96Y

I need some guidance on tyre pressures for road use and track use.

Check the door jamb for the pressure recommendations.

i have been told by pros that no matter the size of tire the recommended psi on door jam still applies. on my e38 which came with 16" but run 20" i used the recommended psi maybe 1-2 above.

The car would have come out of the factory on run flats. Would those pressures be the same for my setup?

You can use the same tire pressures. I would just put them to the OE pressures that are recommended by BMW, and adjust according to your driving preferences.

The bimmerzone spare tire kit is 135/80R17: http://www.bimmerzone.com/BMW_Perfor...T-E90-KIT.html

Their website says tire pressure should be 60psi - http://www.bimmerzone.com/category/T...pare_Tire.html
