I'll be interested to see what is suggested also. My '54 was a daily driver until recently when I took it apart for frame-up painting. It also has a 350 crate motor with Edelbrock carb. I have checked the rear end ratio but I got about 16mpg with tires that are too big for the truck.

When it is back on the road it will have 7R15 tires on 6" wide rims.

In 2004 I bought a new GMC SWB step side that was tricked out by Regency with 20" wheels. I didn't care for the look and sold them and put the GMC standard size aluminum wheels on. My gas mileage jumped from 15 to 19 even though going down in tire size makes the odometer spin faster.

So that's something to think about when you're going for the big wheel/low profile look. Another plus to the regular size tire is they cost half while they last twice as long.
