Tyre life

Can anyone suggest appropriate rear tyre life on a 933. I run 18" Michelins and with merely spirited road use get 4000 / 4500 miles out of the rears. Wear is pretty even, a little more towards the inner that the outer as you would expect from the negative camber it runs as standard. Wear is marginally harsher on the nearside. Geometry has been checked and is good.
I do about 5k to 8k miles / year. Is there a better choice than Michelin for durability?
Thanks. Tony
 
I'm getting more than that from my Michelins. Over 10,000, so you must be enjoying yourself more than me! Includes small amounts of track use, but also a fair bit of motorway, where it's tough to have fun. C4 probably also spreads the wear to the front - replaced my rears a little early last time because the fronts won't quite go far enough to match double the rear use and I was moving up to a new N number.
 
You should be getting more than 4 to 4.5k out of them, I’d think. I had PZero Rossos (until I found them hard to get) and got 8 to 10k wear out of them, with mixed driving style. You shouldn’t have any more wear on one side to the other either. I also run them at 4psi lower than the recommended 44psi(!) for the rears, as at 44psi they can wear much quicker in the centre of the tyre. Have Continental Contact N2 on the back now (as I couldn’t get the PZeros at the time) - when the PZeros are finished (soon) on the fronts, I will match up with Contis there too[;)].
 
Get a second Geo check at another garage, preferably a indy, with normal and race set up experience and inform them of your wear rate. Some of the most sophisticated equipment in the wrong hands is a total waste of time and money. Ive had soft Pirelli Corsas, with pretty extreme geo, and done a handful of trips to the Nurburgring in a season, with 80 or so sub 9 min laps,including 400 motorway miles each way plus a few outings at home and got way more than 5k out of them!!

Many thanks guys, you have confirmed my suspicion that all is not where (or wear maybe!) it should be in terms of geo. I will go get it sorted. Cheers
 
My Michelins have done 14k both front and rear on the 993tt with a good depth of tread still on them, I do mainly long journeys in it.
