Can I do anything with these tires?
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.

Re: Can I do anything with these tires?
I thought I read that PB dropmembers can fit a 10" wide wheel in the front and 11" wide in the back, but now I can't find that. Maybe I was thinking of Roadster Shop. Their site says a max 295 in the front and 345 in the rear.

Re: Can I do anything with these tires?
Far as bolt pattern to fit, would adapters work? That'll space em out a couple inches more and might help?

Re: Can I do anything with these tires?
A spacer would work, and would be required as a minimum anyway. They're pretty shallow and I think on a truck you'd want a deep lip. I think if they were a 5 spoke I'd try a little harder, but even then I don't think they would look very good.
Edit: I posted a picture, but I took it out because I don't want this to look like a for sale ad disguised as a request for advice. I don't think I can post for sale ads, and that's not what I meant this to be. So I'll just leave it focused on whether or not the tires will fit, on wheels that are meant for the truck.

Re: Can I do anything with these tires?
Easiest way is to measure.

Re: Can I do anything with these tires?
I don't have any of the parts though, so there's nothing to measure. They might fit now at stock height, but I'm not going to keep it that way.
I should just call Porterbuilt I guess and see what I can get away with.

Re: Can I do anything with these tires?
I am running a 20x10 with 305/30 tires on all 4 corners. Just use spacers to clear. Wheels have +50 backspacing, with 1.25" spacer up front, and 1.5" rear. i could even cut down to 1" in the front. You will need them as an adapter anyways.

Re: Can I do anything with these tires?
Right on, that gives me some hope for the tires. I might be in tough shape as far as the wheels go. My wheels are 20x10 +23mm and 20x11 +43mm. That wouldn't be the end of the world though, because like I say, they probably wouldn't suit the truck.
Eventually I'd rather go 20/22 or 22/24, so this is just a temporary solution, and whatever loss I'm trying to avoid now, I might have to take when it comes time to sell the 20" wheels. So maybe I'm no further ahead. It's just a thought that popped into my head.

Re: Can I do anything with these tires?
The front biggest issue isnt the offset. Its the spindle nut that sticks out of our hub. modern vehicles have unit bearings.. so i needed the spacer to clear that more than anything. you would need an adapter though. The rear would still need about 1.5" adapter.

Re: Can I do anything with these tires?
Right on, thanks. It'll be a while before I can do anything but I'm going to keep your build thread handy.
