http://speedville.us7.list-manage.com/tr...mp;e=7cdf837b04TIRE RACK just released this latest comparison... granted, none of these tires are 200 TW. I have the BFG G-Force Sport Comp-2 in size 255-50-16 (340 TW)... mounted on 16x8 mini-lite rims (bought rims/tires mounted from PHJ426 last year), which I drive to/from hi-speed road course lapping events... they perform very well on road course lapping events, highway and street ("street" never counts because you just can't drive fast on the street... IMO). These tires ranked #1 by Tire Rack in their most recent test.. (So, I'm further pleased with them!)
Size 275-40-17s seem to already be limited in 200 TW tires on the market... not as many offerings as, say, 275-35-18 and up, etc.
For any pylon/autocross event (parking lot, etc), you want at least a 200 TW tire or softer, but beware, because many such 200 TW tires have minimal tread depth as compared to full tread common tires...
Look at club/class rules and if there's any sponsorship/contingencies involved... usually that's what dictates who runs what tires at most of the events.... especially the major events on national levels of competition. Some clubs already have discounted sponsorships with local tire dealers.. again, check your clubs to see what's up.
For pylon events, you want a tire which has shallow tread depth.. not full tread street depth.. as the blocks will squirm and chunk.... very common if the tread is deep! Another option is to take your favorite full-tread depth tire and have it "shaved" to a shallow depth.. that's what everyone used to do many years ago (back in the 80s-70s)... in fact, you can order tires that way from the Tire Rack for a fee (~$25 per tire to be shaved)... i know that my BFG Comp-2 tires would perform even better if they had less tread depth... but then, I'm driving them to/from road race tracks... figure they'll last me the next 2-3 years or so until I change to something else.. at that time, probably a 200 TW tire and maybe different size rims, such as 18x10 with ~275-35-18 tire.
The Mickey Thompson tires have a 300 TW rating... they're probably an excellent tire for street/hwy/road course having common full tread depth... but they wouldn't be very good on a pylon course unless the tread depth is reduced.
Alex, with your car, I would suggest you seek hi-speed road course events to enjoy your power more to the limits; the pylon events are, too often, too tight for big cars, but they can still be managed and be fun.... I know you have some experience.
Good luck.
