Question: Correct tire sizes??

[vettebob]

Hi,

My 1987 Vette has 255x50R16 tires on the back, and 245x50R16 on the front. Is that correct or should it have the same size on all four corners?? I need to buy tires, should I go with the 255's x 4?

Thanks,

255/50/16 all round from factory

there were some that had 8.5 in front and 9.5 rear.

I prefer to have all 4 the same size so they can be rotated.

Hmmm... ok, I guess I better measure my rims then.

Thanks guys,

Only '84 Z51 cars got that combo
Base '84 -'88 cars got 8.5" wide all round ;
'85 -'87 Z51 /52 cars got 9.5"

But they all had the same size tire from the factory regardless of what rim width was fitted

First C4 tire size change came with the 275/40/17 fitted to the '88 Z51/52 option cars

Rim width is cast on back of wheel

Well that's interesting. Mine is a 1987 Z-51, but it has 245's on the front and 255's on the back. I'll dive under it and check the rim sizes tomorrow. Hopefully the rims are all 9.5" and I can run 4 255 size tires.

Thanks a bunch for the feedback!
