17.5 tires

[d6peg]

I am looking at getting a new lowboy to haul my D6r on, which weighs about 46000 to 48000lbs and needed to know if anybody has had any experience running this size of tires (17.5inch). I would like to find a lowboy with 22.5 low pros but they are hard to come by. I am looking at getting a hydraulic tail and not the detach. I would like to get a detach but the places that I have to go at times is way to unlevel.

thanks

17.5 tires are fine. They are on many lowboys. I have a 16 tire Murray, and it is about the perfect trailer for these things. Loads over the rear, so you don't need to detach unless you have something that won't clear over the back. It has 17.5's on it, and the short tire makes for a low load angle.
Used to have an older model with 22.5's, and hated it. Too tall to get many things over the rear.

Don't be afraid of the little tires, they are tough enough.

I have been running 15 inch 18 ply and have had nothing but trouble and just didnt know if the 17.5 would be enough.

I have an older lowboy that use to have 10.00x15 tires that was on split tube type rims.The tuble type was always flat and the split rims was a pain and unsafe to fix.

The rims was getting old and the split ring sprung from lots of fixing over the years.

I decided i was tired of the hassle of tube tires and rims so went with the 17.5 rims and tubess tires.Now if i have a slow leak and can still pump them up if not completely flat and at least get the dozer moved if short haul before getting them fixed and the tire repair guys like them a lot better.

If the tires are getting to end of life i just plug them,but always take them to get removed and patched if new or low miled.

I have a three axile lowboy and just replaced the back to axiles with the tubless tires and rims.The front axile hardly ever gets a flat.They just run over the nails and kick them up so the other rear tires are the ones that go flat most of the time.

I like the new detach lowboys that has the rear ramps to load over the back beside the detach.I really like the new Eager Beaver trailer with the over the rear ramps in a detach:usa

We have had a TrailMax TRD-50 tri-axle trailer for about 8 years now, and have never had any problems with its 17.5" tires. This trailer can carry 49,000 lbs. with the axle spread it has. The newer TRD-54 with 17.5" tires has a longer axle spread and can carry 53,950 lbs. The only difference between the 2 models is that the TRD-50 has a 49" axle spacing and the TRD-54 has a 54.5" axle spacing.

And I know quite a few people that own TrailMax tri axles with the 17.5" tires and have never heard any complaints about the tires or the trailers.

I sure do like the look of the murray ez-tail.

I sure do like the look of the murray ez-tail.

on the easy tail we use 235/75R17.5 and on the 16 tires we use 215/75R17.5.

The 235's are rated for 5675lbs mounted as duals so that would give you a weight cap. of 45,400 for a 8 tire trailer for that axle group.

The 215's are rated 4540 mounted as duals so that would give you 72,640lb cap. when on a 16 tire type trailer. I dont know of anywhere that would permit you for that kind of weight but you have the cap. to do it.

thanks Chaz,
I talked to someone out there about the ez-tail just the other day.

You prob. spoke with my dad, Doug Murray. He is the only one that currently is doing sales....I do at times if he gets busy.

I normally favor Michelins but the stock continentals have done me well on my Murray.

I Also had a 22.5 16 tire before this one and low profile Of the 17.5s makes it a much better unit.

I did have 17.5"s on a 6 horse trailer and HATED THEM! the Michelin 16" XPS rib tires were a much better tire for that application and would last twice as long as the 17.5"s

With small diameter wheels it is good practice to check the tyre temps and hub temps periodically on long trips . They are spinning much faster than the truck tyres to keep up and can get hot (excess heat blows tyres) . Oil hubs are better than grease as it seems to disipate the heat better and also keeps the bearings wetter than grease as you are relying on the heat to melt small amounts of grease to run into the bearings .

Going from 10-15 tube type tires to tubeless 17.5's is a big step up.
