Hi,

I would go fot the twisters shore 35 of shore 37. It with give you the ultimate grip on your track.
I found that the twister tires are available here Twister tires at very low prices.

A great thing is that you also get huge discounts when you purchase more tyres.

You can see the prices drop on that shop when you purchase 5, 10 or 20 sets front and rear tyres. This goes for both 1:10 and 1:8 scale tyres on all available shores.
These tyres compared to Ufra, Pmt, Grp, GQ tires, Jaco, Enneti, Ellegi, grp, speedmind, x-tires, grp gadini, sp racing, GP speedtires deliver great performance for an even better price. I mostly use shore 35, shore 37 and shore 40

These tyres are available for both touring and 1:8 scale cars such as serpent, mugen and kysho.
