My fiancee, Sharlene Mac Eachern also lost a spare while prerunning Thursday afternoon. I brought this up at the drivers meeting and have had no response. The wheel is an Ultra Wheel with a used BFG 10x33-15. The rims are very hard to come by and that is the only one of two spares I have for Sharlene to run the Parker 425. She went right back out for it and someone had already picked it up.
