Have you guys seen these? Its a wide tire that replaces dual 22.5's. I saw one today, 445/50r22.5. These things look so wild, I'd kind of like to try to fit a set of 22.5x14's for in the back of the dually, but the tires are only rated at 75 mph

 

Not that i would necessarily recommend it but it should be all right...

They are rated for 75mph at full load (which would be 8500lb per tire).

Unless you really overload your dually you would never reach those weights and therefore would not create the amount of heat that might cause tire damage.

Even so 75 should be fast enough for most diving and short bursts above that probalby would not be a problem.


Just my .02.

 

I'm not serious really, just impressed with the 44.5 cm wide tire, especially one that can handle commercial weight. They look pretty sweet.

 

I see them all the time, both on trailers and on tractors. Some guys hate them in the snow -- the contact patch is wider than two duals, allowing easier float and skid. I also hear from drivers there is no margin of safety when you get a flat -- the whole tire shreds quick! There is a substantial reduction in weight over traditional duals, so they can haul more freight legally. I can't decide if they would look cool or too pro-street on a dually pickup.

 

Ditto on zulu for the pros/cons. They're also more prone to hydroplaning. They are, however, less likely to follow the grooves in the road, so they are better for handling.

They are also better for MPG because of the reduced rolling resistance (two sidewalls instead of 4) and lighter weight.

 

There's a difference?

 

We see them all the time on the Flying J and local log rigs. Yeah, they can carry extra weight, but it not nice to have blowout! Not much problem with hydroplaning, we live in semi-arid desert. Icing can be a problem - haven't seen any chains that fit.

 

I've worked with them before. On place I worked at used them on frameless aluminium dump trailers and on some tractors. Actually they are very easy to mount and dismount from a wheel. It was nice not having to change 8 drive tires when they wore out. The drivers liked them and hated them.
