Can I do anything with these tires?

[SKR]

I had a 2014 Camaro that I put wheels and tires on. I sold the car this spring but the guy wanted it with the stock wheels and tires, so I still have the aftermarkets in my garage. I've been trying (not very hard) to sell them but so far I haven't got any interest.

Eventually I'm going to lower my 81, probably with Porterbuilt parts or something similar. The height should be fine, but the width might be a problem, especially up front. The fronts are 285/35ZR20 and rears are 305/35ZR20. Is there any way that these will fit, without any more work than PB dropmembers would require? The wheels and tires don't take up much space in the garage, but the tires won't last forever. If I can make something work with them I'll hang onto them, but if not I'll have to dump them.

It would be nice to use the wheels too, but that would take either a lot of work to get the offset and bolt pattern to fit, or send them back to the manufacturer to get them rebuilt. Sending them back might be best anyway, since I'm not sure the 10 spoke wheels would look very good on the truck.
