Hi Randy,
You can run any tires you wish, even straight ally or steel rims without tyres i guess would avoid blow outs if youre thinking about very high speeds.
1.1 km start, 1 km timed, then 1.1 km braking stretch. the finish is just a wall of snow- no catch line.
Dont think anyone from Sweden (apart from the Hayabusa) will make it 300 kmh, the studs slow speed down by about 20 %.
If you plan runs over 250kmh you need a roll cage, 4 point seat belts, and a protective ring around the drive shaft.
up to now we`ve only ran single direction, so if youre wanting a proper world record, check first with us to ensure a return run is possible - as that will be back towards the depot.
Good luck, Ellwood
