Tyre Pressures

NavG · 07-16-2012, 02:38 PM

Hey, basically curious what tyre pressures you guys would recommend for my current setup.

I'm running Bridgestone Potenza's all round on OEM 19" MV4's, 255/30R19 91Y on the rear and 225/35R19 88Y on the front.

BMW suggest for front and back, 2.4 bar and 2.9 bar respectively. Curious whether you guys adhere to their values or would you advise something a little different for me?

Pretty sure on the door sill it says 2.5 and 2.7 - that's what I run and when BMW recently replaced a rear alloy that's what they had put the pressure to - this was on a 335i though so not sure what bearing that has

Tyre pressures vary dependent on engine size and body shape, so stick with what's on your door sill.

I run mine at exactly what's listed on the plate, and find it pretty spot on - even tyre wear and a comfortable ride. Start with 2.4/2.9 and see how you get on, you can always fiddle with them if you feel you need to.
