16" to 17" differences

[JeffP1167]

I need to run my 90 vette tires before flat spots set in. The downside is the car isn't registered so I am curious and nobody has been able to answer this but will these 90 vette rims fit on my 97 camaro.

I tried one of those tire calculators at least I think I used it right and came up with very minimal differences between 245/50/16 & 275/40/17 .. I think this to be important due to my car having 4l60e and as you all know tire sizes might affect shifting but I am more worried about ABS issues.

I've looked for offset info for the camaro rims to find out if they are the same as the vette rims but struck out there.

Using this calculator this is what I came up with. Does this seem right? or are these online calculators very accurate?

I found a thread where a member says all 16x8 4 gen f-body rims are 55mm offset.

 

[JeffP1167]

Okay so the 88-96 base vettes used a 56mm offset for all 4 rims ... So they should fit my 97 camaro.

I think I've seen "sawblades" on a late F-body and your 90 wheels are the same dimensions. Don't worry about ABS, that system doesn't care what wheels are on the car.

stock size on my 99 Z28 was 245/50/16, i had 275/40/17 and 315/35/17 for years, never a problem.

So your abs didn't care and did you have a auto? You probably had the same rims those star looking ones right?

 

[MYBAD79]

yes, the 5spoke ZR1style. ABS was fine, speedo and auto tranny as well.

A couple of years ago Corvette Fever magazine, now labeled as Vette magazine, did a pretty comprehensive article about tires for C3 Corvettes. From what I remember, you have a much greater selection of modern tires if you have 17 inch wheels. With 16 inch wheels, there was only a few tires that were rated as performance tires. For 17 inch wheels, there was a much
greater selection. I bought 17 inch wheels for my 68.
