Patch from the inside, if its on the safety zones of tire. No good if on the side wall or 1st two rows of threads from the sidewall.

 

i've had a repair job that's held but for nearly 2 years and i don't notice lost of pressure in the tire more than the others, it was a plug repair near the center of the tire between the treads, but I drive it like a regular car, don't know how the plug would hold up if tracked or raced or if driven really aggressively on the streets.

 

What's the realistic risk of autocrossing a car with a tire that has been patched? A flat tire, which is easy to change. BFD. It's not like you're driving 130mph and risking a blow-out at speed. You go faster on the interstate than you will at autocross.

 

Plug and patch from the inside. Plus inner liner sealer on the....err....inner liner.

 

The plug has a pretty good chance of being ripped out. You have to open up the hole pretty wide with a rasp to install the plug. Rapid air loss could mean a beat up wheel or something worse.

Or get it plugged and patched for $0-$10. Whichever.

 

I've used rope plug on a Hoosier autocross tire. Worked fine. I did the patch less than 5 minutes before a run. Ran on the plugged tire for several events after that with no issue.

^ Agreed.

 

it's always the people who never autocross who always worry about damaging their car at an autocross.

i had a tire pop on my bike at 90mph. (2 wheels, lol). i didn't even crap into my leathers.
