I get 10K minimum on 285 30x18 SO2s--and can stretch it to 12K as we have had drought conditions in GA the last 2 years This includes 4-6 track days per year.

4K=heavy foot at stop lights.

Chris,
Nope, no heavy foot on stop lights either... <img src="graemlins/cussing.gif" border="0" alt="[grrrrrrr]" />

Still suspect we have a softer tire mixture over here in Europe... <img src="confused.gif" border="0">

OK RS,
Just thinking, what kind of pavement is it over there? Could it be more abbrasive than what we have here in States? <img src="confused.gif" border="0">

993RS

KC993,
Actually, have not noticed any difference. Do not think it could be that much more abrasive...

[quote]Ray,
I have no alignment problems. Car has been set up by a team that sets up Porsches for the Porsche Cup races in Germany. Also the rears are evenly worn out.<hr></blockquote>

I intend to agree with Maurice; you likely have it set up for max. handling (considering the crew you had work on it), which means alignment is not ideal for max. wear. Bring the Porsche alignment specs (incl. Euro M030 ride height) into the shop and ask them how close you are to that (and stand back when they start laughing).

If you've got a California "low rider", you might be outside the nominal suspension settings that will keep the tires at a good alignment position during transient driving (car moving up and down, steering the wheels and having them keep good alignment- think it's called "kinematic toe").

Years ago, on old 911s (pre 964), lowered cars needed to have the steering racks raised to keep proper steering toe during driving and turning. Might be similar in rear of 993 with that fancy rear suspension.

Ray,
I know I have pretty aggressive settings, that is why I am down from 6,000 miles to 4,000 miles. That is OK with me. But I do not understand the original 6,000 mile figure before the mods. <img src="graemlins/c.gif" border="0" alt="[ouch]" />
Even 6,000 seems much to low compared to the mileage the other members are getting.

KC993

RS,
I think all the S0-2's are made in Japen, you can verify this from the tire itself also you should find the lot number that the tire is from, means date it was produced.
The S0-2 is rated 140 treadwear whereas the S0-2 P.P. is rated 180. The newest S0-3 P.P. is rated 220. Maybe you should try a set of S0-3 next time.

220 means softer higher wear rate I think, so the SO-3s wear quicker not slower.

The "N" rated tires like the SO-2 wears less than the standard SO-2 PP.

Rocket.

P.S I'm editing this post because the above is incorrect, ooops. That said the SO-3s I had wore out alot quicker than the SO-2's. Work that one out.

KC993

NO, 220 means HARDER LONGER wear. 100 is the 'standard', most of the DOT track tire has wear rating of 80 and/or below that, Hoosier has a rating of ZERO. The normal All-Season passenger car tires would have 300 and up wear number.
Interesting isn't it. <img src="graemlins/jumper.gif" border="0" alt="[jumper]" />

Oh quit it Anir, you know you are just looking for an excuse to mount your new Pirelli POC's on your car. You can fool your wife but you have to do better than that here. <img src="graemlins/burnout.gif" border="0" alt="[burnout]" />

Thanks for the response everyone.
However, I still am baffled. I got only max. 6,000 miles on my original stock 993 (normal 993 suspension settings, unlowered).
When I had my old 911SC, I had Ruf 17" wheels, and 245 Bridgestone wheels in the rear. I would get maximum 7,000 miles on my rears (OK, aggressive settings, sport suspension). It is the 6,000 mile figure which I can not explain.

But at least I found an online tire provider from Germany which sells the tires and less than 50% of what the Porsche dealer asks.

Hi all,
Someone mentioned about road tarmacs being more abrasive and I must say I think that may account for difference in wears. Seems logical.

Having said that, I have SO3 PP on my C2 Cab 996 and I have done 10k so far. Wear is about 60% rear and 20% fronts. My driving style is hard cornering 90% of the time. That is the only reason I actually drive the car, for the cornering at obscene speeds!

Cannot comment on SO2 tread wear but surely, understandably, more abrasive tarmac must cause more wear.

Any tire/tarmac experts amongst us?

Rick

I have the opposite problem - I can't get my tires to wear out quickly enough! After nearly 9k miles on my Mich Pilot Sports (they were on the car from the PO), I still have a lot of treat left.
I need to wear out these tires quicker so that I can tell my wife that I now HAVE TO move to 18" tires on a new set of rims!
...Now, where did I leave those Fikse & Forgeline brochures...
Rick.

Hmmm... Swiss roads are tire eaters? Well, why not? Everything else here is darn expensive...

KC993

OK, one more and I will quit.
RS, the wheels that you have on your car are one of the HEAVIEST for Porsche. Now, I am no expert on tire wear, tarmac or others... I can only speculate and try to do a reasonable guess. The 'unspun weight' could also play into the tire wear I GUESS. I am just as baffled as you are.
