Is it difficult to switch dual rims on a trailer to super singles?

Yes, its as simple as bolting them on. Might want to confirm you have a compatible offset first (0 works with everything, 2" works on some)

 

Also if you plan on running faster than 65 mph you are better off with duals. I know a fleet owner with company trucks set at 75 mph. Super singles do not wear well at all at the higher speeds of 70-75 mph speed limit states. Duals are the only way to go if you run a lot of 70-75 mph states and/or run 70/75 all the time.

 

One of the reasons for the wear seems to be low air pressure. I run them on a few trucks and we figured that keeping them below 110 psi caused them to wear a little faster, so they get checked and filled at 115 to 120.

 

If you blow a tire with duals, at least you can limp to a safe spot. You blow a super single and you are dead right there.

I like redundancy and duals provide that.

 

His trailers are all set up with self inflation systems. He and lots of other say if you're going to run them you either have to be very on top of checking and maintaining the proper inflation, run self inflation systems, or you are guaranteed problems if you don't. With company drivers self inflation systems seem like a must. Don't know what psi he has them set at. He told me something he found to be a little strange but true was that retread super singles on trailers actually wear much better than virgins.

 

They do tend to wear faster in the center at higher speeds (70+), particularly the early generation tires. I still think the 500-750lb weight savings (per tandem) is worth it especially if you travel in states with kingpin restrictions (your super singles can be ~6" farther forward than duals and have the same axle weight)


On the other hand, the KR glider went from SS to duals and is happier than ever...

 

Really? That truck is still around (KR T660 glider)? The one with all the controversy?
