Good info, Ray!

Should I expect to see a substanial increase in tread life on my rear tires with that set up? If not, I would be more inclined to put 16" x 6.5" wheels on the rear so the tires can be rotated.

Reducing rear toe will help. I don't think I'd go all the way to zero, though. Specified range is 4mm - 8mm total. Don't think I'd go below ~3mm. Reduced rear toe-in => more tail-happy handling. AP1 is tail-happy enough already.

FYI, Fuzion ZRi's have a much lower treadwear rating than the Advan's you've been running, 320 vs. 500.

That said, I personally wouldn't run a treadwear rating as high as 500. Wear like iron => grip like iron.

Do you need all-season tires (i.e., drive on snow)? Summer tires will offer much better grip, wet or dry (generally lower treadwear rating, though).

I'd expect around 20000+.

I'd try

FRONT
Camber: -.3 degrees
Caster: 6 degrees
Toe: 0.0 inches

REAR

Camber: -1.3 degrees
Toe: 0.15 degrees or 1/8 inches

I live in Dallas, so as of late the only weather I've had to worry about is rain. I may get the occasional ice or snow in the winter...but when that happens all the roads get shut down so I don't have to worry about driving anyway.

Although the AVID's "feel like iron" I have grown to love them. 500 treadwear is damn good, which is why I'm upset that I'm constantly changing rear tires, hence the reason I'm here asking questions to begin with =P

I actually like the ZRi's. I bought some for a (ex) girlfriend once for her prelude. They did very well until her wheels got stolen.

Also, the AVID's cost $100 each at Discount. Whenever I get them pro rated I get two new rears installed mounted balanced out the door with warranties for $100 every few months. I just don't like going up there and waiting and constantly complaining that their tires suck when in reality it's the fact that I can't rotate them.

Ray is on top of the game today!

Thanks again for all the helpfull information!

For one I don't see how not being able to rotate tire has anything to do with tire wear.

Say you were able to rotate tires and assume that front tires last 36000 miles and rears last 12000.

If you rotate the tires at 6000 miles, the now front tires have 18000 miles left on them and now rear tires have 10000 miles left.

Which means you still have to get a new set of rear tires after 16000 miles.


And if you are going through 500 wear rated tires every 12000 miles then there is something not right, because that's how long my 200 wear rated tires last.

Next time you go in for an alignment ask them if you can sit in the driver's seat. And also check how much your alignment has changed since the last one. Lastly try to find a more reputable alignment shop.

I'm running 225/50/16's currently in the rear. I read the sticky on this forum and it said the correct rear tire size is 245/45/16.
I knowingly did this because the AVID's have a warranty in the 225 and not in the 245.

Could this be the cause of my problem? The 225's are what came on the car stock, however I read something about the contact pathes being different in non oem tires.

ZDan

With a wider contact patch, you'd think the 245's should last longer. Whether or not that turns out to be true or not is something else. It's possible that a wider tire will generate more lateral "thrust" for a given rear toe-setting and wear quicker.

IMO, 225/50 is the more "correct" size for the stock 16x7.5" rear wheels.

Frankly, I wouldn't lose sleep over 225/50 vs. 245/45 either way. I've run both at the track, no biggie.
