Hello all, :wave: I'm new to the site and just started getting back into slots. It has been quite a few years and things sure have changed. I have a couple of 1/32 Flex cars that I plan on trying out at the local track. It's only been over 40 years since I have run on a commercial track. I am also into HO scale and still have a bunch of my old 60s stuff which blows me away at what some of it is worth now.
Anyway, my question concerns fitting tires to rims. In a perfect world one would measure their rims and then pick up the right size tires. Well, it doesn't appear like that is always fesable. My question is what are some of the tricks for cutting down tires to fit rims accurately? I have been able to get the right ID tires, but their width needs trimming down. I know one does not just take a razor blade and chop. Also, what about changing the outside diameter once mounted? Especially with silicones which seem a little fragile. Thanks in advance..
