I have a set of 2005 corvette tires they are goodyear gs-2 emt (run flat). The front tires 245/40ZR18 have between 7-8 32nds of tread.
Each front tire has been professionally patch from the inside (not a plug). The rear tires 285/35ZR19 have Between 8-9 32nds of tread and no patches.

A set of these tires go for over $1,100 on Tire Rack i am looking for $500.

Any questions pm me.

 

ttt no one knows anyone with a vett

 

they've been patched, they are no longer run-flat or speed rated...

 

The patch only lowers the speed rating by one level. So, if you want we can just say that because the two front have patches you can call the a w speed rating (168 mph). not a y rating (186 mph)

The patch has nothing to do with the tires ability to be run with no air. the constuction of the side wall is how that is done.
