If you are running your cars with traction magnets the tires that you use will not be as important, but you should try a variety of tires to see what works best for you. Some makes of aftermarket tires are only made to fit aluminum wheels, if you want to use those you would probably have to replace the entire rear axle assembly including the axle, gear, wheels and tires. Unless you run your cars in formal races an expensive upgrade like that may not be worth it. On a clean track silicone tires have the best grip. Dust will stick to silicone tires and once they get coated they will loose grip. The tires can be cleaned quickly by rolling them on sticky tape. No tire will give you great traction on a dusty track, but dust does not stick to urethane tires, so they will have a more consistant grip if the track is dusty. If there is a lot of dust on the track you should probably wipe it down with a Swiffer or microfiber cloth. If you run on silicone tires and keep cleaning them eventually the track will get clean enough that tire cleaning will need to be done less often.
Rubber tires have their best grip if there is a coating of rubber on the track, it has been said that silicone tires will remove the rubber and spoil your grip when you run cars with rubber tires. My club normally runs only on silicone tires, we have not had any problems running proxy cars with rubber or urethane tires, provided that we conditioned the track by doing lots of laps with the urethane or rubber tires and did not run any silicone tires until the proxy racing was finished.
