Re: OK - Tire questions..
Yeah, I don't know what the curbing situation is in Nelson ledges, but at Heartland Park if you get a wheel over the curbing on the inside it's as good as cut. It ends your sprint race right there.
The videos seem to indicate a near total lack of curbing at Nelson. Many of them often indicate that if you get two off, you'll very soon find yourself four-off.
Maybe we should all be installing mudders on our rides...
