Wheels/tires

Ive read so many threads my eyes are sore. Can I run a 275/50/15 on an 8 inch rim on an 86 Bird ? 15x8. 5.5 bs ?

Id run 275/50's if it were me. I had 275/60's. They fit good on 10 holes but rubbed a bit on steep driveways and hard angles. The 275/50 are almost the same width but shorter and would probably fit good.

235/60 is about the max that will fit up front due to the strut.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

Thanks. So 275/50 on an 8 inch. Cool. I was figuring just getting a 7 inch rim up front or should I go to a 6 ?

If go 8" all the way around if you are buying rims. 275's were a bit bulky on the ten holes. Pretty sure the 10 holes are 7" wide.

If you ever decide to go back to stockish tires, you'll at least be able to rotate them after if needed.

I'm running 235/40/18 up front and 275/40/18 in the rears..they seem to be ok.  the previous owner had 235/50/18s up front and they definitely rubbed on my '87 TC.

275/50r15s keep the Speedo accurate as they are the same height.
