How many miles are you guys getting from your tires?

[Bill in MN]

I have Yoko AVES's with about 4k on them. Noticing a bit more tire noise yesterday I looked at the rears and find they are down to the wear markers. I know they're a softer tire and planned on 15 to 20k out of them but this is ridiculous.

Wear is pretty even save for a bit more on the insides due to it having a bit more camber from being lowered. I had my tire guy check it out and he felt the wear pattern was nothing out of the ordinary. It's even across the entire tread.

I don't do burnouts so the wear can't be attributed to anything more than the added power/torque from stock. The fronts exibit virtually no wear whatsoever.

Who's running what and what kind of longevity are you seeing?

Install traction control and your tires will last longer.

I went through two sets of ES100s, 20k+ miles on each with a couple autocrosses and 2-3 DEs. Stock-motored 535is. I had about 5k miles on a set of Toyo T1-Rs and they were looking fine except the outer 1" of tread was gone on all four after two track events (I really enjoyed sliding that M5 around). But they are still serviceable and, to my knowledge, are still on that car. I have about 30k on my snow tires; they still have plenty of tread but the wheels they are on are bent. At least one of them is.

Even if you are not spinning your tires all the time or doing burn-outs, the additional power will wear the tires quicker. Every time you feel than wonderful force pushing you back in your seat, you are using rubber to do it.

Shortened rear tire life is an additional cost to FI your car just like increased fuel consumption.

My BFG G Force Sports are holding up very well. I was expecting to watch them wear out like the last meats that were on there, but they've gone 2k and they're holding up great. I'd have to measure them to tell you how much they've worn, its certainly not apparent.

Considering the way I drive it, thats pretty good. When rolling on in second gear leaves a trail, its pretty rough on tires.

I'm not too worried about munching tires but less than 5k is a bit excessive.

My tire guy tells me that 1/8" of toe in with a soft compound tire and goodly amounts of power will easily cause the tires to wear at a rate 10 times normal. Doing the math I'd say he's right. Given this, it's time for a 4 wheel alaignment.

Traction control ain't gonna help this one

I've got some super cheap kumho ecsta tires that have lasted a long time. I had them for a while before putting the turbo on and have not replaced them yet. This is driving the piss out of the car on the street, couple track days, couple autox runs, some brief drifting, you get the idea. I've been surprised. They are crappy tires, but they last forever.

Your tire guy has it backwards, it's toe out that eats the inside of your tires. Also it doesn't take a gobs of power.

BTW: Unless you're planning on having your alignment shop install the OE offset trailing arm bushings, aftermarket eccentric bushings, or modifying the rear subframe, don't waste your money on a 4 wheel alignment. There's nothing to adjust in the rear of an E28. Unless you've installed camber plates and modified the rear suspension the only adjustment on an E28 is front toe.

The tire guy didn't have it backwards, I probably did. As you can tell, I'm no expert in this area.

I've got eccentric bushings so it ought to be correctable.

Lots of neg camber will eat the inside of tires. Dinan Stg IV runs 2deg neg. with no weight in the car. This will make tire wear go 2x faster than normal, as the insides, especially the fronts wear in no time even under normal driving.

Russ,

Do you have the alignement specs for the Dinan Stage IV setup. I wouldn't be surprised if they are running very little toein, possibly even a little toe out to improve turn in.

Rich

[russc]

I don't know the toe in spec. Id have to look tonight. I know the neg camber front and rear is -2deg with no weight load for Stg IV.
