Default Molded Inserts

I'm buying some pro compound radial tires for my touring car. I'm doing mostly un-prepped parking lot runs, but very high speed.

Would I be better with a molded insert, and if so.. hard or soft?

Thanks in advance

I'm not sure inserts would matter all that much on speed runs. The tire is expanding away from the rim via the centrifugal response. So, unless you're doing some turns I don't think they'd do much. Intuition says you might as well put the hard inserts in.

Thanks.. I'm not doing like pure drag strip speed runs, I'd like to be able to turn.

I'm really looking for the best traction, without being too much, if that's possible.

Basically the tires I have a re super old and crappy... yeah not the best thing for a very high speed run. Needless to say it got away from me and yeah it was ugly.

Would there be value in soft molded inserts in the rear and harder up front? Would that add a noticeable level of stability? I otherwise feel pretty confident with my setup, but it's in need of new rubber for sure.

All I know is the softer the foam insert the more traction you get.

You might want to fuse foam tyres instead of rubbers.

I have seen rubbers blow out on high speed runs.
