Title: Tyres
Post by: RevTurk on March 27, 2012, 04:11:12 PM
I'm not sure how the tyres in karting wear, all I know from F1 is soft tyres are fast but wear quicker and hard tyres last longer. Will soft tyres drop off with wear? If they will comfortably last a race why would you use hard tyres? How would you use your tyres during practice, qualifying and racing?

I always use soft tires because they're faster. I don't know how it's with drop off etc. I never tested it, but I think it's the same as in real and F1.

My main reason for staying away from softs so far has been to avoid the marbling on the track crashing the game.

beta 6b has fixed tht problem so you dont need to worry  ;)

How long would go kart tyres last? When should I think about changing them? Should you use one set for qualifying, one for practice and another set for the race? Or should you use one set for all 3?

Every session I should do new tires.

as you get a new set for the next set of races you may as well use all the ones you have  ;)

I personally find that the soft tyres come on quicker but also drop off quicker, especially in hot weather. If you are only running races of 5-6 laps, it wont matter but when running 15-20 lap races, the hard tyres are the way to go. Much more consistant over a full race. I find that in cool weather, the soft tyres are fine

In real life I believe they use a new set for practice, then a new set for qualifying and heats, then a new set for the final. That's how it's done in Australian CIK anyway. You shouldn't have trouble with a set of tyres going off over a race distance from wear. Over heating maybe, but if that's the case I'd be revising driving style and setup. In real life you want the softest tyre you can get simply because it's faster, which is why most series have control tyres.

in WSK and CIA/FIA its 6 tyres for quali and the heats and a new set for the finals

to do a flying lap you just put 1L of fuel and soft tyres + the rest of your setup

Please tell me the correct working temperature range of tires. For example, kc3?

If I know, when we reduce the tire pressure - he weaker warming, but in game the opposite.

yes it is wrong ingame but the most here say that is real :D the bst temp is arround 60° ATM i think.

I dont know. But I read, what the pressure in the tires are cold in the beginning should not be different from the pressure in the hot tire at the end of more than 2 psi (0.14 bar). The big difference is achieved ingame  when the temperature of the tires up to 50 degrees. The truth is not the fact that the game reflects the real situation. After all, when I reduce the pressure in the tires to reduce the difference in pressure and temperature, then nothing happens - the temperature rises and the pressure difference increases, too. Piboso need a lot of work on their brainchild, I think...

the most go kart tyres are working best at temp range of 43 - 54 Celsius (110 - 130 F).
Soft compounds favour higher temperatures and hard achieve lower temps. The rule "the softer tire the more grip" doesn't tell always the truth because in some cases the softer compound may go beyond the optimal temp range and the tires will start to lose their grip. A general rule is that you may go as soft as you can go near the above limit (approx 54 C) to get the best from your tires. Another big parameter is the pressure. The higher the pressure the more the temp rises, so if you are in qualifying you put a very soft compound with high pressures and in the race (15-20 laps) you run a harder compound (in order to last longer) with lower pressure. After the race you take the hot pressure of the tires (you must see a difference of 1-2 psi) and the temperature across the pattern. If the inner is about 1-3 degrees higher than the outer then it's ok. Some example to help you..

(Outer-Middle-Inner) : 41-42-43 = too low temps, try a softer compound or increase the pressure
                                    47-51-49 = good overall temp, lower the pressure
                                    46-43-48 = good overall temp, increase the pressure. If the overall temp exceed 54 then try a harder compound
                                    49-51-52 = just about the right compound and pressure

i'll try to make a review for tires in the next days to show the differences in the 12 different compounds in KRP. But i need time by then :)

Another excellent post.

It's much easier, just look at the pressure on the end of the session. When it's between 0.90 and 0.95 bar, it's good.
