Racing soft tires

[Duvorynn]

Hi to all!

Today I've raced with VW 1200 '66 and notice that the car isn't turning with RS tires like it did. Tried SS tires and they were pretty similar like RS so wtf...I've changed setups and change different settings but still car wouldn't turn like it did before.
I've inspected a lot of stuff a notice that ALL racing tires on VW 1200 abd VW Type-2 have grooves...how can that be?
Changed vehicles from different manufacturers and those DON'T have grooves on racing tyres but do on sport and comfort which is how it should be.

I'm clueless.

Thanks for any info.

Old cars have grooved racing tyres if the Honda RA272 is anything to go by. Are you sure the front tyres aren’t rubbing against the wheel well on racing softs when turning? That can limit rotation.
