We typically changed tires once during a race of typical sprint length, but we always wanted to make sure we were well-equipped in case of a blow-out or higher track temperatures eating up the rubber quicker than we expected.
In short, slicks will be the tire you use the most often. Make sure you have plenty of spare sets! Race conditions can change in a heartbeat. One minute, the sun will be shining and heatwaves will be pouring off the asphalt of the race track. And the next minute, there could be a heavy downpour with standing water everywhere. Think of wet weather tires, otherwise known as grooved tires, to work in the opposite manner of slicks.
Probably depends on the type of racing for which the kart was designed. I'm still driving one of multiple enduros from the early '70's. A dirt karts frame is nothing more than a flat spring. That is the way I have always looked at it. Turkey17 New member. Kyle is right. That was one of best posts I have read. If you have something not bent learn it, what it likes, what it dislikes.
Then put your effort into tires. Listen steel does not know how old it is. Other than the adjustable front end what other chassis inovation has occurred? And this is not to say that bent frames aren't drivable or good. I've seen plenty of people on bent karts finish good or win. From what I see new karts are binding getting bent faster by smaller wrecks. Devan Morgan does some pretty big races with a excentrik and still wins races. Barry Hastings Member. I dont believe the chassis wear out as much as the bearings wear out.
That said, another chassis brand did turn to crap after a few races. Basically, if you cant adjust the kart and have it respond then its time to change. Al, your correct with the European way. Some of those guys would change mid event, and some events let us check in 2 chassis, mostly a "rain chassis" so that if it rained you had one already set up and didnt have to change the dry setup.
There are problem with only going to the cheap copies of karts, and or only buying used. One, the new innovations would stop.
The sponsorship dollars would dry up and info would stop flowing. The competition between manufactures actually do keep some prices down. Think about it, IF all there was was Phantom, how much would they cost? Makes sense. It also makes sense that it would mess with setup. Thanks for the responses. I quess the answer is… practice on what you got, race day means new tires, if budget permits. If you want to save some money after you race on a set of tires take them off and keep them indoors and flip them on the rim and you can get a second race day out of them.
One more thing… you say the tire levels off after the initial super-grip wears off. If grip over wear time was visualized in a curve, would the grip be steady-ish mildly deteriorating until the tire is done or is it a more rapid curve downwards significantly progressively less grippy?
The reason I ask is my times got progressively slower as the day evolved. I presume a lot of this is due to ambient temperature falling as the day wears on, but I went from But I will often run my fastest lap in the last practice session or in the final.
If the kart was hooked up and I was driving well, a new set of tires probably would be. Does anyone have an idea for how long a new set of tyres will last before they fall off completely? Hours vs laps vs cycles. I did have a set of well used Vega Whites on the kart when I bought it. They were grippy right up until I could see the canvas on the fronts.
