Speedway trials tyres.

Recommended Posts

Hi all, just wondering if anyone knows if speedway bikes still use 350x19 trials tyres, and if they do, where do they get them.   I think that some of the older trials bike conversions, such as Bantam Trials bikes, would only take a 350 tyre, without extensive widening modifications to the rear suspension.

Speedway use speedway tyres, not trials tyres and all trials tyres these days are 18inch.

If you put a 19" trials tyre on a bantam you would need to extend the swing-arm, and that's all that's needed to fit a proper trials tyre

Speedway use 3.75x19. You could use one at a pinch for maybe a display bike or just arsing about. If you want to be competitive, you will have to accommodate a 4 inch

As has been said , the tread  on todays speedway tyres is very shallow  { even when new }  

and although the tread pattern may look like a trials type there are probably differences in sidewall  & plies etc.
