Best Wheel size for my ride?

hishiad · 07-14-2012, 09:47 PM

Just wanted to get some opinions. Right now it's got 15's on it (factory/stock wheel). I'd like to get a bigger wheel, but I don't want to have to modify the vehicle any to fit the wheel and I don't want to require new parts for the larger wheel... So I guess basically what is the largest wheel size I can get away with while staying stock?

1985 Chevrolet Caprice

Bolt Pattern (in): 5x5.00
Bolt Pattern (mm): 5x127
Offset Range (mm): -10 to 10
Front Center Bore (mm): 78.3
Rear Center Bore (mm): 78.3
Stud_Size: 12x1.5

First off, bolt spacing is 5x4.75, not 5x5, they didn't switch to that pattern till 91. As long as your overall tire diameter, and wheel backspacing doesn't change, your options are whatever you want. You will easily be able to fit 18x8's with no issues, probably even 20's.

Most of them are wrong I've noticed, but yeah, 77-90 are 5x4.75, 91-96 5x5. Other than that, they are the same.

This should work. By the way your car looks sick, and the comment about the fat chicks is priceless, LOL!

I believe the 80s 9C1 got the 5on5 pattern too, might be the source of some "bad info" in some places.
