Question Treadwear V. Actual Mileage on Tires?

I am looking for some rear tires for a '99 996 that will last for a decent amount of time. The car is not driven very hard so a tire like the S02's is a little much for both cost and performance needs. currently the car has the Kuhmo Ecsta SPT's and those wore out within 5000 miles, really disappointing tire. I am running the Yoko AVS ES100's on my 944 and have been very pleased with them so those might be an option. Don't know how they would be as a rear tire on a 996 though. I did a couple of searches on the forum and couldn't find to much info on reasonably priced/decent treadwear tires. I was going back and forth between the AVS ES100's and the BF Gforce Sports as options. If you guys have any recommendations they would be greatly appreciated.

Thanks for the help.

If you are not tracking the car, the standard camber settings from the factory will wear your back tires out in about 10,000 -12,000 miles. If you are not tracking, then dial out the camber to about 2/3 rd the factory setting and you will get substantially more mileage.

In most cases, a longer wear tire will cost you traction. I find Bridgestone to be the best for aggressive street driving. If you run the standard 18 inch wheels, the RE 750's are great.

+1 on the Bridgestone RE750s - I put them on my 996 in March and am very pleased with them so far.

I appreciate the input on the Bridgestones. The treadware seems to be very even over the rear tires, would this still indicate a need for adjusting the alignment?

It is highly unlikely that your rear tires are evenly worn out in 5000 miles on street driving. Look again at the inside half of the tires. If they are in fact worn out evenly in 5000 miles, your camber is not within specs and you may have other alignment problems.

+2 on RE750s. On my other car, they lasted 25k of hard street driving and a few AX.

If you are wearing your tires uniformly but too fast, check the toe settings.
My 996 had huge rear toe settings (2x factory!) and i got thru a set of rears in under 5000 miles. Almost perfectly uniform wear.
I put Bridgestone RE050A PP's on and these wore very well and had great grip too. They were at great prices on TireRack at the time (last Sept)

I wish BS made the RE050A PPs in 315s.

Currently running PS2s and on the rear, I have about 8K miles on them I believe... I'd say 65% tread left.

Continental Sport Contact 2 N2 are possibly the tipe to get more mileage up.

Rear tire wear on the 911 is caused mostly by the toe-in and camber. Cheap tires will wear out almost aas fast as better ones since you are essentially scrubbing the tire along the road as you drive. Rear cambere and toe-in are needed to ensure stability when braking and cornering hard.

Treadwear ratings cannot be compared from one brand to another as they selected by the manufacturer as opposed to a standards body. Within a band a tire with a 400 rating will last longer than one with a 140 rating.

Now if it was me, I would recognize that I am driving a very high performance car and use top quality tires. I would be especially concerned about water evacuation and wet grip. Cheaper tires often use rubber which gives up adhesion in the wet for longer wear. One minor fender bender will cost a lot more than tires and I won't talk about an accident!

Put it another way. You can afford a 911. Do you buy your suits at Walmart?

Best,
