Wide tires

You're talking about super singles . Some OTR fleets have them . Yes , they can handle the weight and they improve fuel economy . Last week I saw one have a blowout on a drive axle going downhill on I-71 in KY . Memorable ride for that driver and luckily nothing got hit by that huge 'gator .

 

We've run super singles on our trailers since 1990. The trucks are truck and trailers and in Nevada at the time they would not let us run super singles on our drives. I know Unical in CA ran them on all their axles. We've had great luck with them and I've blown a tire and all it does is go flat. We haven't had any tread separate mainly because we do not use re-caps. The idea behind using super singles on tankers is because it will reduce rollovers. The axles are wider and you can reduce some weight. Which for a gasoline company means more gallons.

 

Yeah , I didn't think they retreaded super singles but there for sure was one big 'gator when it blew . It was one big piece , not several smaller ones . I checked and yup , they retread 'em . http://www.moderntiredealer.com/t_inside.cfm?action=art_det&storyID=1125

 

The problem I could see with these right now is having problems on the road with one and having to replace it.It would be pricey plus finding somebody who carried them.

 

They run about 800 dollars new. If you lose one though you cant limp on down to the tire shop, it will have to be a road call. They wear funny too. However they are considerably lighter than duals and a lot easier to chain-up. I would use them as a company driver, but as an O/O I wouldn't.

 

Yeah, they've capped them for a few years now. But we've proved with other tires that the weight we haul and the heat on the road you just don'y save any money at all. It's best to sell your casings.

 

I'm told that they don't handle nearly as well in snow/slick conditions as duals. It'll be a time before I can find out for myself - May doesn't use 'em

 

Robertson's is to the ready mix industry as Swift is to freight-Safety records that is. Avoid them if you can.

 

Thanks, GasHauler, for explaining this! I noticed a while ago that trucks delivering gas to the local Wawa have super singles, and it was the first I'd seen them.

Oh... and I'm not saying they're not around here, but I'm a four-wheeler and am generally more focused on where the truck is and not so much what's on either end of the axle.
