 So let's talk tyres. First off the front tyre, not really so important. Most of the work is going to be done by a suspension but the important stuff is back here. The rear tyre. 19-inch rear tyre. We've run tubeless right now, which is really quite interesting. It's only come about in the last couple of years really, more so this season. All these tyres distributed at the beginning of the meeting, so the boys don't bring them with them, so they can't doctor the tyres. The compound, the structure of the tyres is the same for everybody. Interesting thing though, if you come round to the back, is that these tyres will only do one race per side. So if you can see here, this side of the tyre has been worn, so this side of the tyre will have done one race. This is a brand new edge. These boys will have spare wheels with them, so they'll have five wheels. That means ten edges basically for the night. The tyre will only do one race before it loses traction. The start is so, so important, that's why they won't have a fresh edge. In speedway we're constantly turning, so it's always the side of the tyre will get worn. The centre will get worn a little bit, but not so much. Tire pressure is also something that's really important. I've been talking to the boys and it'll be probably between 7 psi up to maybe 12 or 13 psi, which is a big difference. What that comes down to is rider preference. It's all about a feel. Most of the stuff for the speedway bike for a rider is more about feel as opposed to statistics. Because if the tyre is softer, you'll feel the tyre roll more, but with it being tubeless, you can't run too less pressure because you then be in a situation where the tyre may come off the rim, which you don't want to do because you don't finish a race with no points, no prizes. So for me as well, it's all about the feel. The tyre pressures are something that, depending on the traction, if the track goes slicker, they may run a little bit less pressure to enable them to get more traction than windraces. So in speedway, tyres may not seem quite so important. Obviously you associate with F1 MotoGP where it's a fixed surface and the tyres and the compounds become hugely important. In speedway, it's a forever-changing surface, so you may think the tyre is not so important. What is important is the pressure. Like I said, that's a real personal preference. Tire pressure can make some big gains if you get it right.
