Traction issues on 245 PSS

alexmtl_135i · 06-21-2013, 08:33 AM

So I've had my PSS for a couple of months now, and well I have to say I'm not super impressed. Maybe I was expecting too much?

The tires have a lot of lateral grip and a lot of grip in general when warmed up. The thing is most of my dayly driving is short and tires are cold, and I find myself spinning more than I would like. My only other mod is a JB4 on map 1.

Anyone had a similar issue? Also, I know BMW has increased tire pressure a lot during my last visit, so I need to bring them back to a more acceptable level, which will help traction. At what PSI do you inflate your non-run flat tires?

I run 36psi as well, with a stage 1 tune. 1st and 2nd are tough to get grip from a rolling pedal to the metal start. Though the turns rolling on the throttle they grip as well as I was expecting for a flashed 135i. I have 225 front and 255 rear PSS.

That's what I run as well myself and yeah the lateral grip on these tires even when cold is stellar

Ok thanks, I'll try 36 psi then. I love the power but I want to feel more acceleration and less spinning
