I have no experience with running urethane tires on a 1/24th car and my experience with silicone tires on 1/24th cars is limited to commercial tracks in the '60s. It is harder to diagnose tire problems on a plastic track than on a wood track. If your tires are even a little out of true they will make a drumming noise on a wood track, on a plastic track that noise would be masked by the noise that a car makes when it passes over the joints. From reading what you have posted elsewhere I gather that you only run on urethane tires, that would rule out the problem that you would have if the tires were getting coated with the residue that silicone tires might leave on the track so simply cleaning the tires is not the solution to the problem. You did not say if your tires were glued or if you were running on an oval or a road course. You also did not say if your cars wanted to slide around much when they are on fresh tires. On an oval track the tires would start to cone and would need truing for that reason, it is much less likely that you would have that problem on a road course. You also did not say how you were truing your tires. If you are using a machine you can easily get the tires perfectly true, otherwise you will never get them perfect and that may be the reason that they tend to go off rather quickly.
Part of your problem is that you are running 1/24th scale cars, which are not terribly popular, so the selection of tires that you might try is limited. Silicone tires are a lot more durable than urethane tires and they also have more grip providing that the track is perfectly clean. It might be a good idea to get some Quick Slicks silicone tires that fit Carrera wheels and give those a spin in "as is" condition. Even without being trued those might have as much grip as trued urethane tires. Silicone tires are much more difficult to true than urethane tires, if you needed to true them you would probably have to use a machine of some sort.
