What is the biggest 18" dirt-track tyre you can get?   umm 18 inches...

I am not convinced that the tyre with every third row missing (paddle) would be allowed as it would tear up the track just like a knobby?

im off to bunnings as that wooden knobbed tyre looks the ducks guts just think all of the variations u can try and you can use old bald bitchy burner tyres the shops will give u for nothing too As to that other paddle type tire I thought that why knobbies arnt allowed on the rear for dirt track/long track becoz theres not much warning between hanging on in a controlled slide and being flat on your back on the track with other racers trying not to hit you

[TT5 Matt]
