Mounting tires inside out, outside in?
Due to lack of camber, not sue if this can be done to even out the wear.
The GY Supercar tires and many others are marked clearly on the side walls ‘this side in’ or ‘this side out’. Just want to know what’s the reason, and consequence (especially on very high speed) if they are mounted inside out.
I’m sure it is not a rotation thing because the left and right tires are rotating in different direction anyway. Does it have anything to do with the structure of the sidewall, like the outside is built stiffer to handle corners? Or, is it because of the tread pattern, I notice the inside and outside pattern are not the same.

Incidentally, you can set up a C6 to handle really well on the street without wearing out tires unevenly.

It's the asymmetric tread. These things are designed to handle with the rain-tirey part toward the inside and the big blocks on the outside, where they come in to play in hard corners. Regardless, it's better to have a worn inner edge than a worn outer edge at 10/10ths.

Because of lack of camber, I have the outside worn more than the inside, not from street use tho.
Any concern for high speed usage if I do swap them?

If you've worn the outsides of your tires your toe is probably off. I'd get the car aligned and leave the tires alone until it's time to replace them.

I'd be concerned, assuming you could even find a shop willing to do it. Not that I've ever tried, or would be willing to try.

I’ve found this information on the Eagle F1 Asymmetric on the Goodyear web site. On the Asymmetric model, the side walls are built differently. The inboard sidewall has a layer of aramid to maintain even tread pressure on the road to enhance grip while cornering, and of course it works in conjunction with the outer tread zone (big block). Mounting them inside out would just defeat the Active CornerGrip technology, shouldn’t do that. I don’t think it’s so much of a safety issue, just less cornering capability.

I couldn’t find anything about the structure of the Supercar sidewalls, I guess both in/outboard are built the same.

I would also tell you that it is only going to be with those tires.
Having a number of different sets on my cars, the GoodYears always wore 'funny'. No changes to alignment, but a change to tire would not only increase life of the tire, but also how the tire wore.
There is such a thing as building camber into the tire itself, but I don't know if these do or not. I would say there is something going on with how the tire is built because of the way they wear.
I would have thought the alignment would match the tires.

Which brand and model works best for you?
