Default Tire additive for tyres that have lost grip?

Hi There

Ive some Sorex rubber that have seeming gone hard & lost all grip
They arnt very worn at all, but have lost that tackyness & are almosr unusable from lack of grip compared to new tyres.

What compond can I use to get some use out of them, just for practice ??
-local rules dont allow tyre componds at race meets

What causes this lack of grip given they arnt very worn ??
overcooking on the warmers ?? tyres getting too hot on ashfelt ??
Cheers

I'll give it a try, thanks.

Ive tried simple green : coated the tyre with it & put tyres in bags still wet.
Does seem to make them tacky, dont think it helped much though. Perhaps the tacky coating came off after the 1st lap ??

Try lining the inside of your tires with duct-tape aswell

Do they allow traction additive at all or just on race days? If its none-at-all you might get away with Jack the Gripper as it smells like dirt and nobody will ever see it. I don't condone cheating so be sure you and your locals are okay with whatever you do. There isn't anything quite like not having needed to cheat to win.

If the surface looks worn but a little hard, perhaps you are experiencing the same problem as I did. What happened to my sorex tires was that my car was understeering really bad, so the front tires got warm and picked up all the rubber pebbles on the track and created a thin film of old rubber on the tire surface.

What I did was to get some simple green and used a scrubbing pad (scotch brite) and removed this layer. After scrubbing, the tire looked like new again and performed flawlessly.

I also coat the tire in WD40 or synthetic engine oil overnight to make the rubber nice and soft.
