Hoosier has come out with a newer version of their A70 13 Street TD for Spridgets and such; called the TDS. Anyone out there with track experience with this tire? How is this tire different?

The TD(S) has a stiffer sidewall. I do not know whether that is faster or not, and I'm not sure if you can even get the regular TD anymore.

Hoosier TDS

PhilsTS.com claims to still 'ave the "old" ones: http://philstireservice.com/pages/tires/tires_hoosier_6.htm

The bigger question now, might be what do the small bore 13" cars use for rain tires now , the selction seems to be drying up quickly. I know alot of folks at vintage racing pack up and head out at the first drop of rain, but I kinda like driving in the rain, and others do as well, but rain tires for vintage cars are becoming harder and harder to come by.

A good All-Weather street tire is pretty hard to beat in the rain. You don't even need wide wheels. A narrow tread with lots of air works best.

I believe Hoosier Dirt Stockers are still made in 205/60-13. You will run circles around anyone on street tires!

The Hoosier TD*S tire is slightly faster than the older compound. They also seem to last through more heat cycles than the Goodyear Blue Streaks and cost 20% less. They are great for practice or qualifying but in an actual race in a big bore car, they will start overheating after 4 laps and by lap 6 they are 3 seconds slower.

So what would you think is the optimum race tire for a big-block Corvette Alan?

The older Hoosier TD's are still available aren't they? Most guys are looking for something that can be used at least for several events.

As usual, I called up Bob Woodman and ordered my Blue Streaks for the Atlanta historics last year. The tire salesman told me about the "new" T.D's that were "just as good" as the Goodyears and $20./a tire less. I drank the Kool-aid and ordered a set.
First two laps were great. Sticky, predictable, could throw the car any where and recover easily. Then started getting rear wheel hop under braking and having to brake way early. Had to take a more conservative line because the "new" T.D's were acting exactly like the old T.D's. Was off a couple of seconds a lap that race.
At the end of the race I had my old G.Y's re-mounted and lap times picked back up.
