Caught this pic of a truck with super singles on the front drive and duals on the rear
I've never run super singles, but I imagine this would handle really weird. Thoughts?
No it wouldn’t drive any different. It could be a lift axle truck or a 6x2. Or that’s just what the fleet had available to make it work lol
Legal as long as the axles match their opposite side. Shouldn't make much difference in how it drives. obviously super singles are more prone to hydroplaning so the whole truck would be but less than having all super singles in the back.
Even if they don't match side to side it's legal
Technically no. All tires on an axle must be the same size.
It's rarely enforced...but it can be if/when desired.
CFR 49 section 383.xx
Solve for x for me
So you're saying you can't mix Michelin low pro 22.5's with any other brand legally.
I'll need a cite on that one
PART 570—VEHICLE IN USE INSPECTION STANDARDS
Subpart B—Vehicles With GVWR of More Than 10,000 Pounds
§ 570.62 Tires
(b) Type. Vehicles should be equipped with tires on the same axle that are matched in construction and tire size designation, and dual tires shall be matched for overall diameter within one-half inch.

Technically, on duals one could have a 24 low pro and a 22 tall and be legal since the overall diameter is nearly identical. The brand isn't the issue, it's the diameter that matters.
Was it a Volvo? Could be a lift axle. That is the standard setup for the UK with the wheel being steered as well although I am pretty sure every US truck lift axle is non steered.
Looks like a Volvo VNL daycab
A lot of lift axles are steerable in the US.
I know for trailers but which trucks have steerable axles?
I drove a W900 that had one, it all depends on how it is set up. Also have them rated for 12,500lbs - 20,000lbs.
Cool, so it's an addon rather than a standard thing? I have looked but only ever seen dual lifts on the likes of Volvo trucks.
I suppose it was a midlift but have thought something like a w900 would benefit immensely from a rear lift.
Mostly 4+ axle trucks. There was a guy on here years ago who added one to his truck. He was always messing with it trying to get it to work right.
Really? Damn that's interesting.
Some are steered some are not but they don't use SUPER singles in UK. Just a regular single.
had this done after a blow out, repair shop didn't have any trailer trash tires so they put on two singles so i could get back to the yard and have another double wide put on
Chances are the axle with the duals is the drive and the other is a lift axle. 6x2 setups are becoming pretty common in my area with outfits that usually run lighter weights but occasionally need the extra load capacity.
And?
