Can I use full tread Toyo's for DE and novice schools? I'm looking to keep my costs down, so I'm trying to avoid buying a set of drys and a set of wets. I want to get away with 6 tires this year. Since Dave questioned the ability of full treads holding up at Lime Rock, I'll add that I'll mostly be at Lime Rock with these tires with a couple of trips to Watkins Glen. The only race I'll see this year is after the Glen school in October.
