I work in a tire shop that sells only BFG and Michelin products. The G-Force Sport is definately more of a summer tire. While it says "all season" on the sidewall, I've heard nothing but bad feedback from everyone I've sold them to regarding wet and cold weather driving. I live in Seattle where it rains for pretty much 6 months out of the year, so I try not to sell that tire to anyone using it year round. As a summer only tire, it's great for road and moderate track use. Too many heavy heat cycles though and the compound will break down and you will lose traction (watch out for tiny cracks in the tread). Next time you replace your tires look into the G-Force Super Sport A/S, it's pretty much the T/A KDW NT with a better tread life and lots of sipes for water evacuation.
