They're not legal up here in manitoba, or any other prairie province for that matter.

They would be perfect for my application. Currently I run:

1220 rpm at 55 mph

1340 rpm at 60 mph

I usually cruise at 60 mph

If I put on super singles it would move up to:

1300 rpm at 55 mph

1410 rpm at 60 mph

A little more livable.

 

Do you want to run super single or the new wide base low profiles? If you want to run the new style I just read an article where a head honcho at Bridgestone said unless you're getting more revenue because of being lighter than duals you're wasting your money going to them. Furthermore he said the fuel mileage claims were not enough reason to go that route. Now this is from the guy that wants to sell you tires. Makes you wonder about these van haulers using them doesn't it?

 

It would be worth it for me because my truck is a pig, not only that it would bring the RPM's up. Much better then changing out gears.

Also, the handling of the truck would be improved. I would like that.

 

Won't you get about the same change by going to low pro 22.5's on your duals? My steers at 275-80R-22.5's are almost the same rpm's as my X-one's.

 

I hear it's comparable, but not quite the same.

Still twice as many sidewalls.

 

My concern would be this:

With conventional duals, if you blow a drive or trailer tire, you can limp to the next exit and get off the highway and out of danger somewhat.

If you blow a super single, you're dead in the water, right where it happens, and....by the time you get 'er stopped, that expensive 13" wide rim may be history too.

 

Yeah that can be an issue, but I believe that super singles can definitely be more reliable.

With a dual setup, if one tire is 10-20 psi lower then the rest you cant really notice it unless you put a gauge to it. By then, the tire might be damaged.

I don't think super singles will blow out anywhere near as often as long as you take care of them. With duals, one tire can scrub real bad.

I've been running single for 2 years and have been happy with the tires. However, it seems that there is an issue with my suspension that has just recently been identified by KW. Because SS are not the norm, they could cause issues that aren't initially apparent. This is something that seems to be specific to this transmission but it does heighten my awareness of the potential for problems.

 

a driver i know ran super singles. he had a flat & someone had to travel 200 mi (he said) to bring him one.
