I have 3/32's remaining on my rear tires and 5/32's on the front's of the original Goodyears. (Less than 11,000 miles) Should I replace the rears now or can I get another summer out of them? I would like to put Michelins or Bridgestones on but really don't want to buy all four if the fronts are still good. Thanks.

Hit a puddle at 55mph and I think you will get you answer.

You will love the Michelin's.

3/32s is marginal at best, and that would be on dry surfaces only......as stated in above post, I would not recommend driving on your tires in rain, you may find it far more 'exciting' than you'd like.

Michelin PS2s came on my 427 convertible and I am very happy with them in all aspects of wet, dry traction, noise, ride comfort, and tire wear, only thing I don't like is that they tend to pick up a lot of sand and small rocks because they are so sticky when warm. Also should point out that the PS2s, like all ultra performance summer only tires, loose significant traction below 40 degrees and should not be driven below 20 degrees.

I hear that once tread gets half worn the tire's performance is significantly hindered.

Now we are talking about stopping and lateral grip etc. at performance levels in dry.

Rian is a no brainer, the more groove depth the better. In a dry climate one could argue that running down a little more on the depth would be possible if just Sunday driving.

If going to non runflat from rf I would get 4 new.

Otherwise staying rf's replace the fronts now and wait on the rears. I would put the new on front and wear the rears out.

Being a Corvette going 4 new is what I would do.

I just replaced my fronts only but I'm not sure I'd do it again. I never had any performance issues but for some reason it just felt unnatural to have mixed tires and brands.

Michelin Pilot SS tires will last a lot longer than the original Goodyears, so you might as well get new all the way around assuming you can afford the outlay. The other Michelins will last longer too. I don't know why the Goodyears wear out so fast because Michelin, and other brands, seem to perform better and last longer.

Thanks for the info. I am a bit apprehensive about switching to non run flats without a spare.

I replaced my GY F1 Supercar RF's at 4/32" at 11K miles because they got very dangerous to drive in any rain, and I was scared of getting caught in rain while on a road trip, so before we left on that 3 week trip, I replaced all 4 tires with a non runflat, got a compressor, a plug kit, a can of slime plus a pair of side cutter pliers in case I needed to remove a nail or screw. I have OnStar as well just in case.
I could not believe the significant decrease in road noise, much better traction in the rain, even when they got down to 3/32", and they lasted twice the mileage of the GY RF's.
3 years later, I replaced those Firestone Indy 500's with another set.
We do a 3-5K mile road trip every year, with many mini trips during the season, and I've never worried about having non runflats on my car.
The odds of getting a blowout, or slicing a sidewall out of a tire is pretty rare. I did pick up a screw on one road trip, was warned by the TMPS, I pumped up the pressure at the next pit stop, and actually plugged it later that afternoon in the hotel parking lot. During our trips, we drive only during daylight hours.

BTW, we stopped overnight in Rochester last summer during our 2 week road trip, on route to Akron OH, Bowling Green KY, and Nashville TN.

Any tire you get, including RF's will be way better than any Goodyear tire in all categories IMO.

Change out those worn out tires before you regret it.

I didn't think you can use slime in the tires with the tpms.

4SUMERZ

It's supposed to ruin the TMPS, but I'd only use the stuff in an emergency, ie: if the air compressor failed. I've put 60K + miles on the car, 50K with the Non Runflats, and have only picked up 1 screw in all those miles, and it caused a very minute leak where the screw was imbedded in the thread.
I never expect to ever have to use the Slime.

Thanks. I think I will go with the Michelin Pilot SS and get a pump, etc.

Is there any difference in tread depth between the GS and base with the Good Year tires?
