Super single questions

Yes but the lightest GCWR is a function of the base chassis and axle configurations. The VNX is standard with 46k rears and 16k-20k front axles, hence the base rating. Usually the VNX’s are built with the 20k axles with 16k springs, in my region anyway. Was 500lb weight increase over the 14k I believe from memory, might be wrong. Check on the ride height, I think once you swap out the low aerodynamic front bumper and remove the chassis fairings there ground clearance will be the same, if not the VNX will just have a front spring spacer wedge, it is in the Volvo parts catalog, can be installed on any Volvo front end.
I am not trying to talk you out of the VNX, I do like the VNX. Maybe next one will be a VNX, waiting to see if Volvo will give us an integrated option with more than 500hp.

If you decide to run singles and want the best mileage you may check out the adaptive loading option.

If you do go super single, follow the example of Prime and other companies that are fully super single. You’ll want to invest in the technology to monitor the psi 24/7 or perhaps in some airlines that can self-inflate the tires if they do begin to lose air, say, from a nail. I too will recommend getting a spare tire.

 

If you’re looking for a light truck, look into Freightliner trucks or the Kenworth T660. Throw in all aluminum alloy wheels.

 

I thought you said you wanted the weight savings. It sounds like you fell in love with the VNX.

—Edit

Be careful with the super singles as they may not necessarily save you money in the long run, especially if you’re a relatively new driver who’s still learning how to properly maintain tires and take care of a truck that can negatively affect tire wear.
