I'm sick of eating tires every 5K miles on the inside. The tire looks brand new and I get the cords on the inside. I know these cars run a aggressive alignment, so has anyone changed to a straight up tire in the rear? Any issues?

 

If the car has an aggressive alignment it is because you ask for one or the shop gives it one either on purpose or because it doesn't know to align the car.

With a proper standard alignment rear tire life should be 3 times that 5K miles and I've managed 4 times.

Get the car to a qualified shop for a proper standard alignment. Be sure to get a before and after printout.

 

You and 95+ % of the people on here do not get how the suspension on these cars works. Flattening out your camber to Zero would cause some really gross handling traits and the tire wear would not be what you expected.

All the different angles of all the components work in conjunction to do specific things at specific times.

A very good handling alignment in the back and one that is very friendly on tires is this. 1.9mm negative camber per side, 1.75mm to 2mm combined toe in. Getting the toe spot on from side to side is a very crucial thing. If you want proof I can show you pictures of the tires that are coming off my car tomorrow. The insides just went bald and the out sides have about 1/32" tread left on them. You could not ask for any better wear in my opinion.

I only get about 4000 miles out of the rear tires I run but I use a Yokohama AD08 which is a fairly sticky tire that is not know for its great longevity.

 

to average 6k miles per set of rears is normal. if you *drive* the car, not much is going to change that. i have never ever heard of anyone getting anywhere NEAR 15k on a set of rear tires. except macters' anecdotal report just now. that is difficult to fathom. i align approx every 9 months, gt2 spec.

 

I run zero. car is way harder to drive. Most guys will run zero to qualify then go back to a more driver friendly setup. I run zero to get max tire contact when squatted. As engine guy said it is very important to get your side to side number dead on, this will take some time and be prepared to pay for that, plus you may need adjustable toe arms to achieve this. Surely if you are lowered.

 

If the alignment is factory I can't imagine how the car is driven to wear out the tires in 6K miles. Even in the case of a "bad" alignment the tires on my Turbo lasted 8K miles.

In one case of a good alignment they lasted nearly 23K miles and had enough tread left (3mm) that the right rear tire with nail in it was replaced free of charge under road hazard warranty/coverage I had on the tires.

Regardless of how one drives, he should ensure the alignment is correct. That's about all he can do unless he wants to change his driving style to one that is easier on the tires.

'course one can I guess run any alignment one wants as long as he can find a shop that will do it for him and the car's adjustment ranges permit it but he must be prepared for possibly abnormally short tire life and possibly a quirky handling car.

 

your success with tire wear is inspirational, but i won't get my hopes up. i have been through many sets of tires and am fairly diligent about keeping all adjustments to my car, adjusted. most particularly alignment.

i have never gotten more than 6k out of a set of rear tires. i think our driving styles may be vastly different. that might tend to simply explain, the disparity between our experiences vis a vis tire wear.

 

Yes, it must be driving style.

I know the Turbo can break the rear tires loose at will at almost any time in 1st gear so I tend to be easy on the throttle taking off and going around corners.

I learned years ago the best traction control system was my right foot and my control over it.

I'm very aware every time the tires spin that's money down the drain. Since I drive a lot of miles per year if I can get 20K miles or more out of a set of rear tires that means I only have to replace tires every year or so. If I only managed 6K per set I'd be broke buying tires 3 times a year...

 

breaking traction at will..agreed. don't ya love it!? so i burn through tires and try to repair my spoiler myself. while you save on tires and have a dealership repair your inoperable spoiler. proving only there's no "one right way" to do this stuff, and that either way, we all have to pay to play

 

The type of compound may be the difference as well I run Nitto invos and hankooks

 

i've never tried nitto's but was leaning toward trying advans 08's and ended up staying w ps'2s again this summer. i think the hankooks are softer compound than either oem pirelli or the michelin. i prefer the harder compound tire, not that longevity seems to be affected much either way.

 

The Yoko's 08's are stickier then any of the tires you mentioned, I think they are super tires for even wet weather.

 

Yawn, can someone get this man the keys to his Toyota Prius.

 

thanks. was going to try them.. i'm sure i've exhausted the remaining CONUS supply of old ps2's that could be had 600 a pair rear!.. now that my next set of rears will be 1100 and change.. i'll look at options again. i think the advans are next. not too concerned about rain/inclement weather out here. we're down to about 3 days of rain per annum

 

I can see how this would get old if you drive a lot. Since I put less than 5k mi on it a year, no issue for me.

That said, my tires wear pretty evenly. Maybe your tire pressure is off?
