Post tire deals? and how many miles should they last?

Anyone knows about a good deal on tires?
I did get about 6k miles on my rear tires and they are with almost no thread left on it. I am currently using 255/40ZR-17's in the back, which is an expensive proposition if I go for the Continental ContiSport Contacts again. The front has about 70% left.

How many miles should I get on my tires? I would assume more then 6k miles. I drive fairly fast but don't really do anything crazy to hurt my tires (no burnouts or any of that stuff).

The answer to your question is "Depends". Alignment, tire manufacturer, tire rating, driving style, road conditions, tire pressure, average load carried, towing, etc. all contribute to tire wear.

So far, I've put about 10k miles on my Pirelli P7000 Super Sport All-Season tires. They look like they may last another 5k miles or so. YMMV.

With a treadwear rating of 300. the BFG ZR-4 all season tires that the PO installed for me managed to last about 30k. I was getting close to the wear bars when I decided to replace. Compare that with one of my SoCal928 neighbors, who showed up at a recent event with absolutely no tread showing at all!

Skins were replaced with some C4 new takeoffs, Michelin Pilots. With a rating of 150 or so, they appear to be a 15-20k tire maybe, based on the first ~4k of measured treadwear.

As Ed says, your mileage will definitely vary. Tires and gas mileage seem to be close-coupled to the pedals, steering wheel, and the odometer. Big movements in any of those components maens less tire life remaining.

I should mention that the new tires (now 18 mos on the car) are a lot more tire than the BFG's ever dreamed of being. Even slightly crippled by the fronts in 205 profile, they still stick well enough to drive big circles around the old ones.

Next set (in another three to four years as the miles are going now) will be whatever the then-current version of the Pilot Sport tires look like. They get a slightly better treadwear rating, and good stick is maintained. I'll also go up to a 225 or maybe a 235 front on the 7.5" rim, with 265 or maybe 275 in the rear on the 9" rims. Outside clearance at the fender will be the limitation.

I'm interested to see what mileage others get in their 928's. My suspicion is that the readings will be all over the spectrum, based on the fun quotient that folks extract from the car.

Go with the Kuhmo Ecsta Supra 712's. I'm running them on my Supercharged Mercedes and they work great and last well past any other high performance tire I've used. I'd say they are by far the best deal on the market!

Tread wear numbers are only meaningful when comparing tires made by the same manufacturer. A 300 BFG is not necessarily going to last twice as long as a Michelin 150. For that matter, a Pirelli 300 and a BFG 300 will not last the same either. However, one can reasonably expect a BFG 300 to last about twice as long as a BFG 150. YMMV.

As for the best deals on tires, I buy mine at COSTCO. I run Bridgestone Potenza 730s and when I was pricing them I found the following prices (approx). The all included the out the door price with road warranty and rotations, COSTCO also included wheel balancing.

Bell tire 175.00
Discount tire 165.00
Tire rack 129.00 (That was at the door, still needed mounting)
COSTSO 124.00

I have around 10k miles on them and they are getting ready for replacement. I Autocrossed on them all summer and ran 10 events. After each event I had them rebalanced and rotated for free. I can't touch that deal anywhere else.

I typically buy two sets of tires every year so I have gather a lot of experiences with different tires. I just bought a set of Yokohama ES100, replacing the AVS Sport, for my Mercedes and they are Great. They are at least equal to the Dunlop 9000 and far better than Kumho 712. The ride is great and it sticks to the road. The only drawback is the sidewall feels a little soft compares to the AVS Sport and the S-03, but for everyday use this became a benefit. And they are priced right.

Most warehouse stores/clubs don't carry the tire sizes I need - namely "Z" rated (or better) All-Season 225/45-17 and 255/40-17. The folks at Intersport will match the Tirerack prices and mount and balance them for a reasonable amount. I don't pay for shipping, but I do pay the tax. YMMV.

Maybe I wasn't clear enough in my first response: the projection of remaining life on the Pilots is based on a tread depth measurement after ~4k miles. I guess that the fact that the UTQG ratings are proportional is a fringe benefit.

Carrying this to another level, your owner's toolkit should probably have an inexpensive tread depth gauge. While handy for planning the tire budget, the bigger value is comparing depth across a single tire. This is the early diagnosis for alignment and tire pressure problems, and highlights them before they become so severe that you have to replace the tires prematurely.

Simple &lt;$5 tool potentially saves $hundreds. Keep it with the tire pressure gauge so you don't forget to use them.

What COSTCO did you go to? The one near me had an attendant that gave me a dumbfounded look when I mentioned the 928's tire sizes for my 16" and 17" rims.

16" = 225/50/16 all around
17" = 225/45/17 front, 255/40/17 rear

I got 13,500 miles on my last set of Z-rated Bridgestone RE-730s, and that was with a poor alignment. My tire sizes are probably the same as yours, 255/40-17 in back, 225/45-17 up front. I liked them so much I bought another set, and I think they'll last longer with a proper alignment. I paid about $700 out the door each time.

I usually go directly to the special-order list at the local Costco store, and plan on a wait of four or five days for stuff they order in. Sometimes they have some Yoko or more likely Bridgestones in stock, but it depends on the area where the store is located. Ritzier locations carry more of the performance tires in stock. None has ever had a problem ordering the ones I want though.

Dave,
I went to the one located in Livonia, Haggerty rd just south of 8 Mile. I think I had to wait a few days as well, but a set 16" Bridgstone 730s for $500. I thought it was worth it.

Thanks for the great response. I think I will buy them at the tire rack and get them mounted for $9 a piece at Costco. I asked in Costco, but they don't carry Kumho, Sumitomo or Yokohama's. I tink I'll go with Tommy's suggestion and buy the Yokohama ES100's.

Here are the prices at the tire rack:

Can I get 265/40-17 instead of the 255's?

012345678 255/40WR17 Kumho ECSTA Supra 712 . In Stock $100.00 $200.00


--------------------------------------------------------------------------------


012345678 225/45WR17 Kumho ECSTA Supra 712 . In Stock $93.00 $186.00


--------------------------------------------------------------------------------


012345678 255/40WR17 Sumitomo HTR Z II . In Stock $113.00 $226.00


--------------------------------------------------------------------------------


012345678 225/45WR17 Sumitomo HTR Z II . In Stock $99.00 $198.00


--------------------------------------------------------------------------------


012345678 255/40WR17 Yokohama AVS ES100 . In Stock $109.00 $218.00

I checked Tire Rack and found Pirelli P7000 Super Sports that are Z rated All-Season. The 225/45-17s are $126 each and the 255/40-17s are $153 each. As I said in a previous post, Intersport (in northern VA) matches the Tire Rack prices, and mounts and balances the set for a reasonable charge. I paid about $30 to install the set two years ago. YMMV.
