Good Year Run Flats

[Deane M.]

A 2010 GS convertible. Replaced the fronts at around 9000 miles. Rears were suspect at the time but ok. Now, 8500 miles later, replacing the fronts again and now the rears. So 6 tires in 18,000 miles. Clearly an alignment issue on the fronts. (not according to GM) Tire wear seems excessive. Anyone having this problem? (not my car, belongs to a friend who is a NCRS member) also, any comments on Nitto tires.
Thanks.

Excellent.
Thanks Vinnie!

I am going to have to stretch to remember all this but. 2008 Z06 replaced OEM tires and wheels at 1K miles (preserving the OEM wheels and tires. Yes I plead guilty to originality disease.). Replaced with Goodyear Super car tires -- OEM run flats in OEM size. 12K miles later had to replace the rears (replaced with the same OEM Goodyears) -- worn on the inside edge to the cord. Aligned the car to take some of the rear negative camber out and less rear toe. Full disclosure: I suspect more than a small amount of the rear tire wear was due to overloading the car on the Road Tour to/from California in 2009. My daughter will be packing lighter for this year's Road Tour or she will stay home.

Replaced the fronts when they had about 20K on them -- again OEM Goodyears. At 32K miles on the car (another 15K on the rear and now 8K more on the fronts) I switched to Michelin ZP tires. Big improvement in ride and NOISE. I like the Michelins a whole lot and would recommend them highly.

If I had it to do aver again I would get the car aligned as soon as I got home from Bowling Green. GM's settings are too "track" oriented. If you do some or a lot of tracking they are great, but if you want a GT car realign it. I have had some discussions with them about offering variable wheel alignment (customer selected) from the factory, but I get the feeling that is more nuisance than they want to do -- even at an extra charge. I might bring it up again in a day or two at Bowling Green, but I don’t think it will go anywhere.

Re: Good Year Run Flats

Terry, you could explain the fundamentals of weight distribution to your daughter, then immediatley duck!. Thanks for the feedback. Clearly an alignment has to be done. But these run flats have a very short life span. 18,000 miles and six tires later, yikes.
Thanks again to you and Vinnie.

Re: Good Year Run Flats

You guys are really getting great mileage on your tires, on my ZR1, they just keep getting burned off . Vinnie, hope that engine you built is still running, mine is running like a champ.

Re: Good Year Run Flats

Sounds like you must drive harder than I. My 2006 coupe has 17,500 miles and the tires still look great. Two long road trips, New Hampshire to Charlotte and New Hampshire to Novi. Plus the Bowling Green to New Hampshire drive after the Museum delivery.

I do suggest you have your wheels aligned.

Sorry Deane, I may have explained that progression improperly. It even confuses me, and I should have gone and looked at the car's log before I tried to do this. I put the Michelins on at about 32K on the odo, but there were two sets of Goodyear rears & fronts (at different mileages) on during that time -- the first 1K was on the factory tires. So three sets in 31K. Most of the Corvette Forum C6 people are reporting 12 to 15K on their tires for street use. Any track time reduces the tire mileage considerably. Both brands of tires I have used are sticky as all get out. They pick up little stones like crazy and sling them all over. That stickiness makes them corner like on rails (try over 1G corners ), but at the cost of frequent replacement. The original tread depth is not very much (have to look up the specs to see what it is) and I suspect that is part of the speed rating, but of course that reduces the life span as well.

I got 12K out of the OEM Goodyears on my 2007 Z06. Right front wore a little more than others. Replaced them with Michelins. They were quieter and I recently sold the car with 18K (6K on the tires) and the tires looked new. No uneven wear.

Re: Good Year Run Flats

I spoke with the Corvette mechanic at the local dealership today. I do not know if this is true but this is what he said.

All new Corvettes are setup and wheels aligned for racing. Meaning, lots of cornering. The result is excessive tire wear. He said to have the car aligned for normal street driving and this will significantly extent tire life.

Can anyone comment on this?

My 2008 has 14 K miles. The fronts are nearing the end due to uneven wear on the outside so the factory alignment was not right. The rears are still good (8/32") and are wearing evenly. I'd like to hold off on replacing the rears. Can I mix the run flats on the rear with Michelin's or Nittos on the front. ????

true because if you set the front camber as close to "0" as possible the tires will not wear out on the in side edge. my new 97 wore the tires on the inside edge and in "corvette news" they had a article about using "0" camber by a corvette engineer

Re: Good Year Run Flats

Terry,
Do you have the Michelin PS2 ZP model (which is a run flat) or the AS plus ZP. ???? The PS2's are more expensive than the AS plus but a quite a bit less than the Goodyear run flats.
