Converting to Super Singles

Low pro 24.5 yes , 24.5 tall rubber, it will lean to the rear........

 

455/55 22.5 is listed as 496 Revs per mile and a static radius of 19.9". Same as 11 R22.5 and LP 24.5.

An 11R 24.5 STEER TIRE has a static radius of 20.1". Because a steer tire typically has 18/32" of tread vs a drive having 27/32" or more, it is shorter. Therefore .2" ( less than a quarter inch) won't make a big difference. Your u-joint at the front diff will run at a slightly sharper angle.

 

Why are you wanting to switch to super singles?

 

i want to know why also.. there's no benefit.. I have them now, and i'm trying to switch back over to duals..

People say that there's a weight saving benefit, but the amount of weight saved doesn't out weight the cost of the tire, and the damage done to a rim in the even of a blow out, not to mention you can't limp down the road with a blown super single.

As soon as i wear these four i have on now down, i'm jumping ship and tossing on a set of duals.

 

I run wide based rubber, but I waited till I ordered a new truck. Just wasn't realistic to switch my last one over. There are many very good regular tires that compete quite favorably with wide based when it comes to rolling resistance and fuel economy issues. Weight saving is there, ballpark 400 lb, but not really enough to justify the cost to switch. I really like wide based on my current truck, but still would not have switched my last one if I had to do it over.

And it has to be done right. I ordered an intermediate length axle that was longer than standard, shorter than wide axle, yet still gave me (or a future owner) the option to go back to duals. And then I ordered 0" offset rims instead of the 2" outset rims some order. This is better for axle bearings. You are not throwing the wheel centering off. Almost 300,000 miles and the tread still is at 17/32nd's on Michelin Xone XDN2 rubber.

Save any ideas about going to wide based for a new truck. Forget the hype about wide based and stick with what you have now. I am a big fan of wide based now that I have been using them for almost 300,000 miles, but I, in good conscience, cannot advise anyone to switch an existing tractor over to them. I would ditch the 11R size tires and go with low pros, as they are more fuel efficient. But that is me. I can't see a good reason to use 11R's, but some folks seem to like them.

 

Buy a quality tire with a low rolling resistance. That would be best for longevity and MPG's.

 

I work with a guy that went from Dual XDA Energys to X- Ones on his drives and found no measurable difference in MPG.....

Then he converted his trailer and found something like .7 MPG but he can't get any life out of his tires. He's constantly getting warranty and goodwill policy from Michelin and the tire dealer but figures if he was paying out of pocket, his fuel savings would likely be used in tire costs.

I'm pretty sure Cowpie has the right perspective on this.

 

Well, I run pre-emission iron also... in a 2013 truck. So you can have you cake and eat it too sometimes. Gliders can be a beautiful thing. It is this one that I ordered the wide based wheels and intermediate axle on that I mentioned.
