Found CHEAP source for F1's!
 

I worked a Car and Driver shoot-out yesterday at Michigan International Speedway. What a BLAST! A (highly modified) Sonoma did a low 10 second ¼, but its automatic transmission fried on the road course. But I digress…

MIS was in the process of installing crash barriers made out of tires 4 stacks deep around the inside of the track. I started looking at the tires they were bolting together. Almost all were new Goodyears. Some were clearly defective, but most looked good to me. Along the backstretch I started seeing a few of our tires (295/45/18 F1’s). Then further down there were stacks and stacks of them! Every one had ½” holes drilled through the sidewalls and tread ready to accept bolts with large washers. DOH! How big a hole can you patch?…

You might have a hard time getting them balanced, depending on where the holes are:D

those are defects from the factory,the holes are drilled in the sidewall so know one can use them we do the same thing at our factory in buffalo

If you try to patch a hole in the side wall, you may want to get a roll cage for racing.....

hehehehe
