Found SAE 5/16 30R9 for $4.00 per foot at autozone. I was going to spend $100 at Atlanta Parts for the "kit" but now am wondering if all of these have to be R9
They have 30R7 and most seem to be the size of 5/16.
Am I off base here?
I do not care about colors....
Are the other off sizes hard to get? Are they not all near the 5/16 size?
What is everyone using?
