My Stingray non-Z51 front tires are wearing out and but the rear tires are not wearing out as fast. Have the OEM summer tires but plan to switch to the Michelin all season runflats. Are there any issues with putting the all seasons on the front and leaving the rears unchanged, until the rears wear out more and then say in a couple of years change the rears to the all seasons?

I just did that exact thing a few weeks ago, service advisor at the dealer never mentioned it would be an issue, I have not noticed any issues with the handling or performance, except to say the dreaded front wheel hop when making tight turns is gone, that is a big plus for me.

When I did that recently the shop owner told me it was OK as long as the two fronts were the same type and the two rears were the same type.

Summer and AS tires behave a little different in different situations. Generally, may not be an issue for you. My OCD brain would make me crazy if I did that though...

I have the same setup. No issues. Then again I don't track it, so any difference in grip is moot. It is interesting how much better the front all-seasons stick when it's below 65F.

No issues from a safety standpoint or anything, worse than could happen is that the tires are different enough in sidewall rigidity etc that the car might feel a bit odd, esp. in corners.

OK if you just drive it normally. If you are the person that pushes it ti the limit, then you mat want to rethink this.

Definitely not. No problem.

Thanks all, I’m just a normal driver so I’ll be transitioning to the all seasons fronts first then replace the rears a year or two later. Looking forward to no more wheel hop haha.

I did that "monkey business" of different tire manufacturers front and rear back in the day when I was young and stupid with bad resultants... Don't do experiments with your Corvette tires!

Doing that causes you to be something of a test pilot.
You might get understeer on dry pavement and oversteer on wet. Or the reverse.
Is there a way to get some used-but-still ok tires so all 4 are similar?

If you drive safe you will be fine. I always replace the 4 tires at the same time. No under/over steer issues when wet or spirited driving.

It is fine as long as the tires in the rear handle better or the same as the tires in the front. If they don't handle as well as the front tires the car will will have increased oversteer when the driver makes quick maneuvers.

Yes the rears are the OEM summer tires with plenty of tread and wearing evenly so they should perform better than the new all seasons.

However the front tires are wearing out on the inside. I’ve read this may be an alignment issue and read somewhere there is a “street alignment” for non-track drivers. Is this true and when I replace the fronts should I ask for that type of alignment (and would Discount Tire know about that type of alignment)?

Gearhead Jim

Tires (front or rear) that are wearing on the inside edge typically have either too much toe-out, or too much negative camber.
Either way, an alignment by someone who knows what he is doing, and cares; is what you need.
Toe should either be 0, or a very small amount of toe-IN.
Camber should either be 0, or a small amount of negative camber. Negative camber will improve cornering but wear the inner edges a little faster.

The 4 Corvettes we have purchased new over the years, have all had at least one of the alignment parameters that was outside of even the mile-wide GM tolerances.
The original alignment is done at the end of the production line, so not much opportunity for the suspension to "settle" after assembly.

The C7 has adjustable caster for the front and rear wheels, adjustable caster in the rear is very unusual. Some dealers don't even know that it's adjustable, fewer still have the proper tools and someone who knows how to us them. The good news is that at least our C7 was set properly when checked at ~20k miles, and hasn't changed since then.
