Tire mileage survey (Actually: Why am I getting such low mileage...)

Jim,
I wouldn't take everything you read on the 'net to the bank. I've owned five different 911's and have consistently been able to get between 10k and 15k on the rear tires without any uneven wear. There really is nothing wrong with the 993's rear frame other than the fact that it is very sensitive to proper alignment.

Another (perhaps the most important) factor is how smooth the driver is. You can take the same car, doing the same course at the same speeds and a smooth driver will get far better tire mileage than an abrupt driver. I have ridden with Viken and he is not abrupt and, consistent with that, he gets good tire mileage.

Don't get me wrong. I readily accept my rear tire wear, but I just started getting curious when other 911 drivers spoke of getting 15-20,000 miles... I have been driving 911s for over twenty years, and never did get much mileage out of my tires. On my old 911SC (lowered, sport suspension), I would get about 6,000 miles. The cars are always aligned perfectly, the tire wear is always very even.

At what tread depth do you (993RS) and others consider it is time to replace tyres? UK legal minimum is 1.6mm, though I reckon most folk who drive in all weathers replace when tread gets to around 2-3mm. Curious to know when folks reckon it is time to change.

JohnM,
Same situation here. By law, 1.6 mm is the minimum, but when driving in the rain, if you are down to 3-4mm, the car gets pretty squirreley. If the weather remains dry, I change them as late as possible. If I have the misfortune to hit a long rainy streak and I am down to about 3-4 mm, then I change them...

You seem like a switched on type of guy.
What road surfaces are they running in Switz. Here we have alot of "chipseal" makes for loud open road driving and quick tyre wear.
Im also concious from living and driving in other countries that concreate vs tarseal can make differences as can temp.
Im wondering if this is as significant factor as I believe it to be or wether its best for everyone to quit this thread while were ahead!!

LOL!
There's your reason right there. 4mm is ~5/32. You're throwing away tires that have half of their tread left. <img src="graemlins/roflmao.gif" border="0" alt="[hiha]" />
