emergency tire split repair on STP--it worked
 

Thought I would share a tire patch job that actually worked for me on the STP.
At mile 170 (of 203) my sons rear tire split 2 inches down the center gapping open exposing and blowing the tube. I didn't realize that how low his tread was, and usually this is a catastrophic non repair. I did not want to spend $100 for a cheap $30 tire at the rest stop--so I attempted this repair

I used 4 large tube patch and heavly glued them on the inside of the tire to cover the spit letting the glue dry. Then removed a Kevlar liner used for flat prevention (Mr tuffy) from a different tire and glued about a 10 inch patch over the tube patches gluing both surfaces and letting them dry. A new tube inserted and put this tire on my front wheel pumping it only to 25-30 psi. The patch held even though the split opened up enough to see the patch and the expansion just cleared the brake pads. I really didn't think it would go 30 plus miles, but it did--and when I got home it survived up to a pressure to 70psi in my garage.

I think the most important thing was to put this on the front where there is 35-40% of the weight, and thank goodness for Mr tuffy. I don't think the tube patch boot job would have been enough.
