wow that's really strange. i run about 35 pounds on my dunlop sport 9000s 225-40-18s in the front and about 37 pounds in the rear 275-35-18s, and the wear is even and only slight after 18 k miles. i think i'll get about 25 k miles more before they're dead bald.

We had a lot of snow over the last few weeks, and they are summer tires could this be the cause? Or are higher speed rating prone 2 a quicker wear rate? Also the fronts are N rated, and the rears are not, hardly any wear on the fronts,

What 18" tires would you recommend?

Had very good results with (Falken 452 tires ) they are good tires for all around uses either wet or dry noise is minimal & very good road handling, plus they won't brake you piggy bank. Had them on my 944 -16" wheels got the same now on my 968-17" wheels so they won't be any problem on your 18" mine are ZR rated both front & rear.And thank for the spelling it will get you lot more answers.

Dont let PZeros fool you! Maybe your situation is different but the center block tread is very shallow and looks bald after a short while. As long as you have lots of tread measured from the channels you should be OK.

Sorry? I think I get way ur saying. But there's little wear 2 out sides, fronts look same as new, evenly flat. The rears look like they been over inflated. R get some pics up soon.

Thanks 4 everyone input

more importantly, how is your alignment? toe wears tires more than camber. camber just wears it unevenly.
