Don't think so.

let me clarify this for you. the F350 SRW and DRW use the same axle

with the same tires on each vehicle the SRW can carry 6500 of tire load on a 10k axle the DRWs tires (derated to 2800 for the DRW) can carry 9600 on a 10k axle.. so yes there is a big difference. now you could go with 245/70R19.5 and vision wheels and get yourself 9000 pounds of tire capacity (wheel limited) on an SRW
