BMW 3-Series (E90 E92) Forum - View Single Post - Non-runflat Tire Pressures--What are you running?

Mr. ///M3 RD · 09-15-2010, 07:22 AM

I am running RFT 225/35/19 Front and 255/30/19 rear

My rear tires have worn inside due to the 2 1/2 degree chamber on my car during a extended road trip. I am told wear is normal on my Z4 due to retractable roof in trunk and some luggage.

Both the tire shop and BMW recommends I run the rear tire 10% above specified air pressure (as listed in door well). I am doing this.

Also, I notice that I loose a few PSI every week, so every Monday morning I check and adjust my air pressure. I keep a good air compressor (with gauge mounted on the compressor in my garage).
