2.2 inch wheels+tyres for an optima buggy (12mm hex)
 

Looking for some used 2.2 inch 12mm hex wheels and/or whees+tyres for an old Optima coming out of retirement....

The car's running very strong, but I'd like to build up a starter set of modern-sized wheels to get it on the track to races with controlled tyres...

Any help's appreciated - thanks!
