Building a special coffee table...suggestions

[DonRotolo]

You can purchase circles of tempered glass in various diameters. I recently bought a 4' diameter one at Pier 1 Imports for just over $100 - a three foot diameter version is somewhat less costly, and sounds like the right size for your tire. Tempered glass is very tough, hard to break, but turns into little cubes if you manage to shatter it - safe

To mount it, I'd suggest dabs of a strong adhesive (like silicone sealer) or something stronger mounted to a few metal studs, which mount through the tire.

Take a photo when it's done!

How about getting one of those round patio furniture tables with the expanded metal type top? I've seen them in various colors (black, white, green) and in various diameters (usually 3' and 4'). Cut the top off and bolt it to the tire. You could probably find one used for pretty cheap and paint it some really cool color you like and even paint the car number of you favorite driver on it or something. Red against the black tire might look kinda cool.
