How many lies are told about kart tyres, find out about all of them

Not prohibited, but very infrequent. First of all, however, we need to clarify what is meant by scraping: using a heat gun and a spatula, cleaning the surface of tyres from any debris or pieces of tyre collected while running on a track. It is a procedure that is never practiced in Junior/Senior karting, because the tyres clean themselves automatically after a few bends thanks to the high speed that these vehicles are able to reach and the use of soft compounds which facilitate cleaning. Also in the MINI classes, scraping is generally not performed and the reasons are almost the same as those just explained. The only, rare, exceptions occur in some races, where the drivers have few laps available and where tyres with particularly hard compounds are fitted, which are therefore difficult to clean directly on the track. This is why, to give drivers a little help, the mechanics under the tent scrape the surface of tyres, making sure that once they get on the track they can immediately push to the max. However, it is a rather risky job, especially for the tyres: first of all, "artificially" removing a layer of rubber from the surface of a tyre can risk damaging the casing, especially if the scraping is done too aggressively. Furthermore, putting the tyre "in contact" with a direct heat source, such as a heat gun, can lead to vulcanization of the rubber, with consequent loss of performance, thus making this practice counterproductive.
