Team Rooket have used the following over the years, Schwalbe City Jet, and Marathon @ 16" 2009 including CSE2009. No problem at CSE (until I crashed) Maxxis Hookworm @ 20" only at Cadwell 2009 (bullet proof, but too slow - use these at CSE and you need to get out and push!) Primo Comet @ 20" 2010 including CSE ( Took loads of abuse - lasted all season including accidents at Catterline and CSE - then run at Dalby that year) Schwalbe Kojak @ 20" including CSE (Excellent slick tyre used at 100psi all season and with suspension you do not get jarring or the cart getting skittish - tyre had to be changed after accidents, the sidewalls are very thin on these. No problems during normal use, but usually scrap if that corner has had an accident - check the sidewalls) Still not sure what we are running next season and may be a mix dependent on event. Hope the above is usefull.

We very nearly did ban kevlar beaded / folding tyres, but didn't in the end because it would be difficult to enforce. I'm still not keen on them though, and if we could find a quick and easy way to prohibit them we would.
It's not so much the speed they will cope with but their resistance to wear under heavy braking. I'm sure you did get over 70mph on them, but I'm prepared to bet you didn't have to then brake as hard as you can to get around a 30mph corner while racing against 3 other people with the same idea as you.
I'd just re-iterate and expand slightly my previous caveat.
1) Test them thoroughly under race conditions, at high speed, high cornering loads and heavy braking 2) Bring an alternative tyre choice, just in case

Graham take your mates back to the pub and get them all to sign up as Marshals, perhaps Stephen might pay for the first round out of the Cairngorm funds. ;D

I would argue that folding tyres (usually expensive and much lighter) needn’t necessarily be any less durable, but here’s an interesting quote from TIOGA.
Tioga Power Block S-Spec BMX Tyre (folding) The ultimate bmx racing tire, the PowerBlock is designed to efficiently transfer pedal power and other rider inputs into lateral motion – in short, you roll farther with less wasted energy.
Tioga’s S-SPEC components are produced in limited quantities utilizing choice materials designed for competition at the highest levels. S-SPEC components are identified by an icon bearing the Greek alphabet “Sigma,” which itself represents the “summation of a set” – a fitting symbol for a line of products combining top level technology with top level materials.
Please be aware that in some cases, S-SPEC's higher performance levels are achieved at the expense of some product durability. If product durability is most important, Tioga's standard products offer exceptional performance values.
Features: • Cylex 120 TPI Casing • Folding Bead • UTC Rubber (Ultimate Traction Compound)10.41oz; 295g • 20 x 2.1 – 11.64oz; 330g • 20 x 1.95 – 10.76oz; 305g • 20 x 1.75 – 10.05oz; 285g • 20 x 1.60 – 8.47oz; 240g

I was following your advice. You wanted heavier(slower) tyres. Banning folding tyres helps achieve that aim (also helps keep costs down). But not all tyres will be less durable just because they are folding. Downhill Racers seem to rate some of the folding tyres they use as more durable than the wire bead tyres. I was pointing out that Tioga do have some reservations about durability of their folding product. Giving “some” support to your reservations? “Please be aware that in some cases, S-SPEC's higher performance levels are achieved at the expense of some product durability.”Bottom line is… Not banned because you can’t police it.
