MSM - What tyre pressure do you keep your tyres at? Since the e46 manual does not show for 18's i have been trying a few different setups but i get a slight vibration between 120km and 140km. I had the wheels balanced and they are not buckled or anything.
Strangely enough I'm getting a slight vibration at around 80 and 120 only and nothing between that. Also fine up to 160 so far. At 80, the vibration is also when braking, so it MIGHT be my discs, but I don't think so.
I was running 2.3 all round. I just changed to 2.4 front and 2.8 rear this morning on the way to work. Will observe in the next few days and let you know.
What pressures are you running and what did you experience the worse/least vibration with.
On my previous (OEM) set of 17s, I had a slight vibration, but increased the pressures a bit and it went away. Will still need to experiment with the 18s.
