Single Wide Rubber

Not sure how they are built over there,but the chassis on singles here would be 12-14 inch wider.
Also I found there were better off road and in soft conditions due to larger diameter and less roll Resistance compared to other trailer tyres we run most trucks run 19.5 inch rims on the trailers some even 17.5 inch.

 

The ability to run a wider frame, thus lowering the centre of gravity on an application like a tanker, is one of the selling features of the single wides.

 

I've always noticed how weird they all looked with the wheels, they look skinnier, like putting 96" axles under a 102" wide trailer. I can see the point if thats what they are doing but you couldn't go back to duals, you'd always be stuck with singles.

 

True 'dat ... it would only be practical in a very few applications.

 

Interesting point, but most tankers are built to "chemical specs", which dictates the height of the trailers, as well as the fifth wheel height of our trucks. This is so the plumbing as well as the dome lid height will be consistent in the different plants. (ease of loading/ unloading, and the fall protection that is lowered around the crow's nest. There is some leeway, approx. 6 inches, I believe. Curious now, gonna have to measure when I get back to the terminal.

 

I see no one mentioned how many drivers have limped off the road, to the yard, or to a tire shop with a flat on the duals.
Imagine a flat single one evening in Detroit.

 

I do know that Schneider is removing the super singles from the fleet. The only trucks that are still gonna have them are the local guys were weight is a issue. I don't know true this is, but one look at the tire racks at their shops tells a lot. On a side note, I would live to try a set out for pulling at the fairs. It would be interesting to see how they would react.

 

I don't think they would do as good as duals, but I' don't think I've ever seen anybody try it

 

I had them on truck and trailer and liked them. Now i have them on trailer only. Got 255,000 on first set on tank trailer. Most fleets are pulling them off because weight and fuel savings or not enough to pay for all the blown sidewalls from being curbed ALL the time.

 

In my limited experience, give me a set of duals anyday. Pull a log trailer with singles and not impressed with them. As has been said, blow a tire and one stops. Although i can dump the air in the suspension, chain that wheel up to the logs bunks and blow the suspension back up. Not pretty, but it gets me off the road.
Running recaps, and the turning scrubs them hard, trying to peel caps off (weight may enter into that?). It is a tri axle trailer, so that adds to the scrub thing also?
The single tire is not as wide as the outside tire on a set of duals. Makes for a hard leaning trailer on corners(again, weight and height may enter into that?).
Just my experience and thoughts............ david
