The rears are down to the wear bars but they have an uneven wear pattern. The outside of the tires have plenty of tread but the centers are worn. Is that from over inflation?

Either that or you enjoy acting like John Force on a regular basis...

JsL · 04-30-2015, 10:01 PM

I think thats under inflation causing that wear pattern.

Over inflation. Go down 2-3 psi.

No over inflation causes center to be over full and wear faster under makes the edges stick up higher and wear faster.

I will give another vote for over inflation. What pressure do you run?

I run the recommended 35 psi. I've only put 3K miles on the car since I bought it. I suspect the previous owner was running more.

pbonsalb · 05-01-2015, 06:45 AM

This is how my last set of rears looked when I was done. I was slightly over inflated also. I think I could have gotten another 10k out of them.

Now that's living on the edge.

Psi?

fhaze3 · 05-01-2015, 08:51 AM

you are a tad under inflated @ 33 lbs/ft. Up it to 5040 lbs/ft and you will be right around 35 psi.

33 pound-force/square foot = 0.229167 psi

33 seems on the low side so lets blame it on the other guy. Mine with ZCP sizes work pretty good around 36 rear.

What tire is that you have?

1MOREMOD · 05-01-2015, 11:22 PM

You would need to be pretty high to cause center wear. 33 won't do that.

SteveInfante · 05-02-2015, 02:02 AM

Maybe your camber is off a little in the rear. The inward tilt would make the inside of the tire wear a little faster then the outside.

35 psi is what BMW recommends. Tires are Continental Conti Contact 3.

White 13 · 05-02-2015, 06:02 PM

I probably would start with the recommended 33 on the next set and watch them for awhile. Factory recommends 36 rear on mine with the 265 tires and 10 inch wheels and works out pretty good for wear with the original equipped Continentals; maybe a little center wear if I remember right.

Unless it rains where you live, there's plenty of meat on those tires.
