I have a love/hate relationship with styrene and resin tires. Simple fact I don't like plastic tires is because the majority of them just don't look right. Now, yes, there are always exceptions- the slicks in the AMT Munster Coach and Dragula kits come to mind, but for the most part, a painted plastic tire still looks like, well, a painted plastic tire. The resin stuff from places like Modelhaus are fantastic, but I really don't want to have to buy a set of tires for everything I build!
I always wondered why some kit manufacturers used a material for the tires known to react adversely to styrene. I've been hearing of this problem for years, I've even seen the results of it firsthand, but the practice continues. But then again- GM used to love bolting steel up to thin aluminum. Aluminum and steel don't react to well together either... that's why you used to see so many RWD Delta 88s and Cutlass Supremes missing the rear bumper.
