I have s10 spares on the front of my A coupe right now. They look awesome but obviously I'm not gonna be doing much driving with temporary tires on there. I really like the size of the setup though. They are 155/90 -16 on a 16x4 steel wheel. I'm wondering what equivalent tire size I might be able to find. I'd love to get some sort of radial on there... but I know they generally don't come that skinny.... will I have to use a bias ply tube tire? Like a 500x16?? I'm just not sure.
