float tires

[fastlt1]

I see alot of these new tractor and trailers running ssuper singles on trailers and rear of trucks. What size tires are they running? What are they using for rims? Are they just flipping front float steer rims out? Thanks.

I have noticed the same thing, and have wondered the same things

We run them on alot of trucks at work, they are a dedicated wheel to run them, they drive tires we run on the trucks at work are 445/65/22.5, I do not think they are front float wheels from say a off road truck or cememt truck, they are a drive wheel.

They do last pretty long, avg so far is about 210K miles, they save a ton of weight, so the trucks can haul more propane/ammonia

what is the mileage life on the skinny tires? since you have to buy twice as many

The normal setup you can get about 220K-240K out of them when kept rotated, but since the super single setup saves about 600lbs of weight, that is more gallons of propane or ammonia that can be hauled each load, and the trucks haul 2-3 loads a day, so in the long run, you make more money.

thats a lot of money saved and made :O

Definitely especially when about 6 trucks are running them, 2-3 loads a day, easier to rotate, etc

My work truck has 445/65R22.5s on the front, but we're still running duals on the drivers. I've heard the super singles do better offroad, but I kinda like the fact that if you blow one, you still have the other one to keep you upright.

The rim is a 22.5x13". The tires are $1200 a piece, but if you're running them on the rear, that'd probably be cheaper than buying two 11R22.5s.

When they blow they take out fenders on the truck and trailer, that is the downfall that you are stranded. normal 11R22.5's are about 450-500 bucks a piece.

So price-wise, they're probably pretty similar. That $1200 was for big-lug fronts (at an admittedly high-priced tire shop I used to work at).

Yes they are about that, we do all our own mounting and rotating at the shop, but they are right around a grand or more.

Eww, I did that for a year or so at the tire shop. I did all 10 on a concrete pump by myself on the hottest day of the year. Its not all that hard (except for not gouging the aluminum wheels), but I wouldn't be sad if I never had to do it again.

I didn't like it much at all, doing any big tire for that matter, I am only 145lbs.....so ya :lol:, but I could do it. My buddy and I found a great way to rotate the super singles, we cut three short pieces of 1" pipe to use as rollers on them and just slowly rolled them off the studs and out from under the fender with no issues.
