Wheels and tires question ???
i have an 87 with 255/50/16 tires on 16x8.5 rims front and back
i would like to go to 275/40/17 on 17x9.5 rims front and back
wanting to use 91-92 sawblades---
1. what will happen to speedometer accuracy?

1. Nothing
2. Yes, offset is different.
3. Less sidewall, less flex, probably won't notice it much unless roads are real crappy.
4. Wil improve depending on tire selection.

Your speedo wont be thrown off enough for you to worry about anything.
If you get wheels from 91-92, you will need spacer plates because the offset is different, wont look right at all without them. I recommend you get the spacer from VetteBrakes, its high quality.
Harsher ride, i doubt it.
Handling, probably nothing you can notice aside from the tire brand itself.

Re: Wheels and tires question ??? (chas stark)
Thinking about the AFS wheels that are made in the correct offset for your 87 is a good idea. To run OEM 17' wheel's you will need a set of adapters (not spacers) and they can run upwards of $200.
You should have no problems with the other concerns. The tires themselves will have some effect on ride quality, interior noise and handling. You can get a whole lot of opinions here on the various tires available for Vettes :yesnod: :cheers:
