Has anyone with 255/85R16's noticed increased fuel mileage over the stock 245/75R16's? I'm getting 17-19 empty and 9-11 towing 14-19,000# trailers with the stock tires and was wondering if the 255's would do any better.

Ordered The Juice on 6-17 from Diesel Injection Service. Version 3.5c built on 6-11 just arrived today. Good service & fast delivery from DIS in TX.
