My BFG's are all 70 or over and it's about the same for those I race with. I tried soaking a while back and could only get them down to 60 and didn't notice any difference. Once I started buffing off the tires with a sander to smooth out the feathering, I started doing better. When I won my first race last year, my right front was at 72 and right rear was 74. I think the hardness will be a key to getting some life out of them. Still the sidewalls are pretty flimsy, but dirt tires have always seemed like tubes with tread on them anyhow. I realize that whatever they went to would have to be a little better than BFG's or they would have to ban the BFG's to keep the folks that stock piled them from having an advantage. Just wondering, how hard are the Federals?
If you look at my earlier posts, I've been pretty much against this move based on my previous experience racing on Hoosiers and AR's, but I'm now pretty optimistic. The tires I used to run on the stock car were 40 to 45 hardness if I remember right (mostly Hoosier RC1's).
