To add to Tony's input. Each tread block has edges, each edge will heat instead of the heat being spread across the entire tread. As the tread blocks heat they will separate from the tire in our application.

What about a pattern more like what jl222 mentioned. Large blocks, not unlike a drag radial or street bike tire? From reading up on dirt car tires and grooving, alot if it has to do with helping to shed heat. Or do you think that a tire without tread is just better for traction on the salt?
The street tires I've seen just have a few grooves curving out to edge of tire with fairly wide spacing [not many of them] and I was surprised that is all they need in case of wet conditions. If I were to groove a tire for salt or dirt I would use at least double the grooves.
I also think a lot of heat buildup in LSR tires is from spinning ''skinny'' tires. Never have taken tire temps but have never noticed our
''wide'' tires being hot. Taking tire temps will be a new chore for one of our crew and I will post the results.
A certain competition coupe blew a ''skinny'' tire at close to 300 mph after spinning them to failure.
I said your spinning the tires going that fast, and he said everybody spins there tires.
We sold our Goodyear 10'' tires after 15 years and did not notice any change in the wear holes,now I wish I had measured them
