Yes, just as Tim said, they allow for bigger tires without loss of power. And like he said too, when I park my stock '49 (with 16" wheels) and the '53 next to each other, I love the looks of the '53 better. The tire to wheel ratio just looks more appealing with more side wall height and tire width.
I have the 750x15 super tractions on my '53 from Walcks. They handle great on the road and have siping in them for rainy conditions. I feel very safe with them. They grab good in snow too. The chrome doo-dads are aftermarket.
