    I have a 78 Camaro that I have fitted C5 corvette brakes (13”) and rear disc brakes I now need 17” rims to get it home, I have found American racing Rodder wheels 17 x 7” & 17 x 8” rears, wheels are 0 offset. What I am hoping to do is run a a tall tyre as I am running 3.9 diff gears on a TH350 auto so will be reving hard while cruising. I also looking for that old school look with a tall tyre. What I want to know
    is zero offset the best thing and what is the biggest tyre I can get under the front guards considering I am running 17x 7” wide rims also what is the tallest and widest tyre I can get on a 8” rim
    Thanks

    Just make sure the center/spoke rim design clears your calipers, this is regardless of offset. Most brake companies have a scaled diagram that can be printed and cut out, or send the pdf file to the rim company to make sure they fit. nothing worse than buying rims only to find out they hit the calipers and need to run spacers that overstress the studs (not good) and push the wheel out and bugger up your fitment.

    My 17" American Racing wheels did not fit the C5 template I cut out. Too little caliper to barrel clearance as there was a "step" in the barrel of the wheel. That is how I ended up with C4HD brakes on mine.

    On a Z28 Stock wheels are 15x7 with 4.5” backspace. 225/70/15 is 27.4” tall.

    If you work backwards to find a 17” tire that is close to the same diameter a 235/55/17 tire is 27.2” which gets you close to stock diameter.

    Those should fit your 17x7 and 17x8” rims fine and if you stay with sto ck backspacing you should be good. However, NO GUARANTEES! Everyone’s car is different. If the front end is lowered that tire may be too tall.....

    I currently run 235/60/15 which is 26.1” on a lowered car with plenty of clearance.

    255/50-17 is approx. 27" and fits on a 4.5" backspace rim on a Firebird. It is a tight fit on the front. Not sure if it would fit the front of a Camaro

    That tall and wide likely won't fit up front of its lowered at all
