Grand National Wheels and Tires
*These wheels and tires are no longer on my GN, but I am leaving this link up to help those that want an idea of what 17" wheels look like on a Buick.
The old wheels and tires on my Grand National were American Racing Torque Thrust II's.  They were originally purchased for my 1988 Monte Carlo SS, but I thought Id see how they looked on the GN.  As you can see from the pictures below, they looked pretty damn good!  If you are wondering the specs, here they are:

17"x8"
4" Backspace
5 on 4.75 Bolt Pattern
245/45R17 Kelly Charger HP Radial Tires

My Grand National had NO suspension modifications.  Rubbing on bumps and full-lock turns was minimal, and ride quality wasnt bad with the proper body braces.
