Hi stoner
Please can you clarify what sort of tyres you are using - do you have a brand name or supplier's name?
I think the tyres we normally use are natural rubber as you describe, but its difficult to be sure we are talking about the same thing.

they come from the USA ken o racing, these particular ones come in donuts 25mm wide so i cut them in half. he also does them on 5 spoke alloys 1/32 axle 10 mm wide by 21mm oa hight . h&r racing does them mounted to wheels and a few more i cant think of at the moment. their all advertised as natural rubber as i said they look like spongies but if you take a spongie and rub it across your track theres no grip ,if you take these tyres and do the same you can feel them gripping , i run them on my track, sanded and glossed ninco,and get good grip.

ken o racing's ebay site says he's selling Alpha Piranah Natural Rubber donuts.
Alpha Piranah is an example of what's often called fish rubber (smell them and you'll know why).
Examples of other fish rubber sponge tyres are Parma Tuna, SCD Roadhogs, JK 'B', BSP, UFRA and many others
Fish rubber is the most commonly used type of sponge at clubs running metal chassis slot cars on MDF tracks (these tracks have copper braid or tape so magnet traction doesn't apply). At higher level meetings, some type of fish rubber is pretty much universal. Occasionally people will swap to non fish sponge (like Parma MX) if they want less grip.

Some clubs don't allow sponge tyres, some refer to non sponge tyres as rubber tyres (arguably incorrectly) so I guess their ban would include natural rubber sponge.

these arn,t fish rubber scroll through ken o,s site and youl find them. the description is natural rubber made for plastic and wood tracks, as you say he sells fish rubber spongies, but these arn,t them. what is the natural rubber you run at your club meets, i cant see them banning natural rubber at clubs because these are the only true rubber tyres availeable. john.

Could be "Wonder Tyres", very closed cell sponge and quite hard compared to the ufra or fish rubber.
I think these originate from Japan and have been available for a few years, ABSlot used to sell them in the UK.
