I have a 2004 CC Coupe with OEM Michelin Pilot Sport tires that have 7000 miles on them. Last week my left rear tire was damaged. When the dealer and I inspected my other tires, we saw that the other rear tire was nearly worn out and the front tires were badly worn on the inside edges. I plan to replace the tires with Michelin PS2 tires. The dealer also recommended an alignment at a cost of $440. Please comment on the following questions:

1. Is the inside edge wear on the front tires common? Dealer indicated that the factory alignment is set up for aggressive driving and this contributes to more wear under normal driving conditions.
2. What is a typical cost for the alignment? Is it worth doing?
3. What is type of mileage are you getting on a new set of tires?
4. Do the front or rear tires wear out fastest?
5. Tire recommendations?

Thanks in advance for any comments.

1). Yes, it's common. Alignment set for slight "toe-in" to enhance handling. If it were set to neutral, you might find that the car wanders or drifts left to right without any steering wheel input from you. Are your inside fronts worn down so much that the tires are bald or even showing the tirecord? If you still have tread there (although less deep than the rest of the tire) you may be OK for awhile longer. Go to the auto parts store and buy a depth guage and measure. Check out Tirerack's guide here:

2). Cost varies, don't know what to expect in your location? Was the inside wear equal on the front left and front right? If so, might not be out of line, but perhaps the toe-in was too much. $440 sounds reasonable.

3). Don't know, my car is new.

4). Fronts wear out faster if your driving style and/or location cause you to brake alot (do you live in the hills and go downhill alot? If so, the front tires and front brake pads bear most of the weight in braking and therefore, more friction to stop the car). Rears wear out faster if you don't, but have a heavy foot and peel-out or accelerate alot.

5). I've had good luck with Michelin PS2s on one of my Porsches. I have Perelli P-Zero Rossos as the OEM tire on my Maserati Coupe CC and I like the tire, no major issues have arisen so far.

Also, why do you need a dealer to tell you that your good rear tire is nearly worn out???? Don't you ever look at your tires? Worn inside fronts is less obvious, but the rears, when viewed from behind the car, are plain as daylight. Is the rubber worn down all the way to the wear-bars? Did you ever notice your car being less stable in the rain? 

Good luck.

5. Tire recommendations?

1. Yes, a bit of inner wear is common. toe-in, or negative camber, allows the car to handle a bit better.
2. $440 for an alignment is pretty steep, a Hunter machine is considered the state of the art, and most places charge $100-$150 for a 4 wheel align.
3. depends on how you drive
4. rears typically wear out faster, the car is a rear wheel drive.
5. again, depends on how you drive. look for tire ratings. every tire has a wear rating, the lower the #, the lower the life expecetancy, however, the soft the tire=stickier/better handling.

you have to ask yourself, is $440 worth the cost of getting a few thousand extra miles out of your tires whic cost $900 for the set?

I was surprised to see the tires so worn after only 7000 miles. This is the first performance car that I have owned. The dealer tells me that this is actually fairly typical for this car. My previous car, an Audi A6 had tires that lasted 20-25,000 miles.

Both of my front tires have worn evenly on the the inside front edges. There was another Coupe in the shop getting new tires that had similar mileage and similar wear on the front tires. I am still debating the value of an alignment, except that the Tech suggested that he could flatten the stance of the front tires to reduce the inside wear. I am concerned about effect on the handling of the car.

Flip?

Excuse if this an ignorant question; isn't it possible to flip the two tires around (left-to-right and right-to-left), so that you can wear the edge on the other side before having to replace them?​

the tires are directional, so flipping would not be possible. I guess you could dismount the tires, but just swapping them in theory would not work.

getting 20-25k on a pair of tires is not really resonable. the A6 from what i recall, does not have Low Profile tires. Low profile tires tend to have softer compounds, as they are designed to be race tires for the street. ...I have gotten 12-15k out of the tires on my Mercedes, which was pretty good.

tire life and a high performance vehicle, don't really go hand in hand in my opinion....

I seem to get 10-12k miles on a set of tires. I am using Pirelli P-zero Rosso's since that is what came on the car. This is with a track day every six months or so. Seems reasonable to me.
On my very first set, I also had the extreme wear on the inside of the front tires. I was shocked to accidently see them worn down to the cords while the outside treads weren't quite to the wear bars. I had it realigned and while I still get the effect to some extent, it is acceptable now. I just keep an eye on it.

I commented on a similar thread some time back and also provided all the alignment settings - sorry, I cant find my notes by you may find them in a search in this site.
I had exactly the same problem on my old '03 4200. I got the wheels properly set up and it made a huge difference - I probably doubled the life in the front tyres!
Try to find out where the dealer gets the alignments done and go direct - my dealer even suggested this to me and gave me the contact details of the specialist.
Dont go to any old tyre shop though as the set up involves changing shims which only a speciallist would have.
I would suggest you get it done. When I changed my car for a new one, I insiste the dealer check the alignment as part of the deal.

The previous owner of my QP got approximately 10k out the back pair of OEM Pirelli P-zero Rossos and replaced them with the same. The original front tires are still fine at 12k.

Thanks for the comments guys. After reading your comments and also searching this forum here are my conclusions:

1. Average tire life is about 8000-12000 miles (depends on driving style)
2. Most folks recommend these 3 tires:
Michelin Pilot Sport II (PS2) (some prefer XL, Extra Load version)
Pirelli P-Zero Rosso
Goodyear Eagle F1
3. Factory Alignment is set for aggressive driving (high speed cornering) with some toe-in and negative camber. This setting can cause excessive wear on the inside edge of the front tires, if most of your miles are moderate driving.

I love this Forum...

Up until now, I thought my front tires were wearing exceptionally well at 9,000 miles.. That is until I checked the inside wear. Nothing too crazy, just a little more worn than the outside. According to this helpful forum, seems normal.

The rears seem fine. My style is not aggressive at all. I am shooting for 12,000 miles on the fronts. I have the OEM Mich. I like to hit a turn or two at speed so I don't think I want to change the alignment and with the price of tires it does not seem that big of a deal.

When exactly should you replace the fronts with their inner wear? Right now they are NOT bald. Should I wait? There is tread all over the rest of the tire.

Thanks.. CM

Dont assume that once your camber etc has been set up, it will remain like that for ever. Bumps, potholes etc will, over time, knock the wheels out of alignment again. If you are going to keep the car for a while, it is probably best to get the set up checked every couple of years.

tire input

Regarding brands.

After getting a blow-out (and not in the mood to wait 2 days for a matching tire), I had the shop put 4 new of what they had available on, Toyo TR1's. They claimed the same rubber/process/facility as the Goodyear GSD3 F1's. I didn't see how that was possible, but the guy had Toyo on the phone and was getting this direct from him. I had no other options so I figured how bad could it be. Pure BS, I've had the GSD3's on previous cars and these Toyo's are crap. They squeel constantly at low speed turns with no throttle input and are causing the car to understeer with any type speed in the corners (no grip at all!), wher ethe PS2's handled it with no problem. I've not been a fan of the Pilot Sports in the past but the PS2's were on the car when I got it and was somewhat impressed. Toyo's are coming off ASAP, just trying to decide if I go back with the GSD3's or try the BFGoodrich my friend keeps raving about. Anyone have any feedback on the BFG KDW2?

I put a set of the BFG KDW2s on my 05 QP about 2000 miles ago. I like them very much, best tires I've had to date and look great too.

I have them on the Spyder. They came dealer installed (Glauser MB in Denver). Wouldn't have been my first choice but I've been pleasantly surprised - ride a bit rough til they warm up but then loads of grip and so far seem to be wearing well.

Tire Options

This was a timely thread. I just purchased an 04 Coupe CC and after 4 days of owning it, the rear drivers side blew out (13k miles on it). I took a look at the tires at delivery, but not at the inside edge. Like the initial poster of this thread, I was not aware of the increased wear on the inside.

My car will be my dailly driver. Is there a harder compound tire that can be used to give longer tire life?

Thank you.

Just spoke with the dealer on this issue with my car.

At 11,000 miles. Some inside wear on fronts but generally good tread depth.
Neutralizing the front camber would even wear and provide benign driving (less tramlining etc.) but I am happy with the handling so will pay for it in tire wear.

On the rear, I'm probably within 1-2 thousand miles (or track day) of a new set. Down to 3-4mm or so. Dealer says they like to replace them at 3mm but I know there's some more smoke in those tires I need to let out. :)

Not really sure what to put on. I love the PZero Rossos on my wife's cars, and on my prior cars.

I'm not really keen on replacing the fronts. They have at least 5,000 or more in them.

Default plan is probably replace original PS on rears only with PS.
