Nutty, the low speed runs need rubber tyres because they are carried out on tarmac/concrete but the highest speed rating for "conventional" rubber tyres is only 300 mph. The tyres on JCB Dieselmax were rated to that speed but subsequently tested up to 350 before being put on that car. By no coincidence, that it where the diesel powered speed land speed record presently stands. That car could have gone quite a bit faster but it was decided to limit the car to 350 mph in the aims of safety/reliability.
