Scuffing Tires

[race760]

What is the proper way to scuff a new set of Maxxis HT3's?

Thanks

Bolt them on the Kart and put a good 10 to 12 lap run on them when the track has good grip in it.
Should of added a few days to a week ahead of the race you need them for, most tracks allow guy's to go out at the end of the night.
