The Indy and Sportsman Pro series are designed for the street but like any performance tire, will not have as long a mileage life as a general radial tire. Both tires are bias ply, not radials so they'll be noisy on the highway.

They don't make a "Sportsman" tire small enough as a replacement for a street car. The smallest Sportsman tire is 29" tall and 12.5" wide. Cars only use a tire that's 26" tall. The Sportsman Pro series offers a better tire size selection.
The Indy and Indy SS series is "old" tire design and sizes. These are used mostly on pre 70's restoration projects.
Your best choice for a performance street tire in the Mickey Thompson line is the Sportsman Pro series.
I used to have BFGoodrich Comp TA tires on my truck. I now use Kelly Charger tires. I have a set of Sportsman Pros mounted on a set of Center Lines when I decide to take the truck to the track.
