20' rim size
 

what size 20' rim could i fit on my stock 1969 camaro rearend

I think you will have trouble fitting a 20' rim on any car.

20x8 on a 4" offset should work just fine.

Call Dave at intro wheels. He has done a lot of first gens without any mods.

note: I was being a smart ass there since he asked 20' and not 20"

Yep, what he said. Dave has owned a couple nice 69s that sat right with 20s
His # is 877 424 8991 in Montclair, CA

Datsbad has had 2 '69s with 20s on the back. Both used a 255/35-20 tire. One had grey centered TTIIs that were 20x8 with 5" of backspace the other had 20x8.5s with 5.25" backspace. Both cars were lowered at least 3" and had Baer rear discs with no rubbing issues. There is a member here Sandros with a '69 that is running 20x9.5 Ralley Wheels with I believe at least a 265 or maybe even a 285/30 rear tire. I don't know if they rub. I think on a very low car at the least they would be very tight and maybe some minor rubbing over curb cuts. You may want to PM him. Good luck.
