For me the 25 & 30 series rubber band tires simply don't work on a street rod, and in fact for my taste they simply don't work on anything. I want to see sidewall in the right proportion to overall diameter & wheel size, nothing less than around a 65 series profile is going to work for me. Likewise, for a '30's coupe I probably wouldn't look at wheel sizes bigger than 17's in the rear, an likely 15's or maybe 16's max in the front. When I see a muscle car from the mid & late '60's running 20's or 22's I gag. It just doesn't appeal to my eye, but to each his own. You only have to satisfy yourself, and have thick skin to ignore comments.
