The price of racing.

most of our local dirt track racers seem to run Hoosiers tires which for some reason were damn near impossible to het last year. A local, very good racer had to pick n choose the races he entered last year and did great but could have done so much better. We even have a local speed shop that takes 18 wheel trucks to the races with Hoosiers and they couldn’t get them. I know guys struggled to get slicks last year too.
Rubber trees have been dying due to a fungus... Producers have pulled the trees and waiting for the new plantings to produce in 3-4 years.

Nylon is scarce as are other supplies.
