Trailer axles

[Anonymous-0]

Looking to buy a 30' gooseneck, cant decide if to get 3 7000# axles or 2 10000# duelly axles. I have herd that duellys pull harder but would be easer to turn sharp. 6 tires or 8 tires to buy, 3 axles to maintain or 2 axles to mantain. Any thoughts on what one to get?

No brainer, get the tandum axle with dual wheels and oil bath hubs. Bigger brakes,bigger bearings. and if you blow a tire on the dual wheels you can still live to tell about it.Tri-axle trailers are very hard on front tires.

[b:9d12e7b76e]It depends where the axles are placed on the trailer, what it is that you are hauling, how you plan to load and unload, how you turn (easy or hard) :?:
It is a myth that triple axle trailers are harder on tires - sharp turns are what shorten tread & tire life on any trailer :idea:
You don't say whether you plan to buy new or used - if used then make sure you have the frame - springs - axles - bearings checked for condition :!: [/b:9d12e7b76e]

I'd favor the tandem dually.

Going straight down the road . . .I don't know the physics of it all to say that having three tires in a row on each side will help you track better than two axles -- the flp side of that is that with two dualies, you'll have four tires pointing forward.

Any axle and its bearings and spindles on a trailer with more than one axle will experience lateral stress on a turn, but triples only add to that stress -- kinda like some of the spread-axle big trailers you see, that only have two. The further the distance between the front and the rear axles, the greater the stress.

The other thing, and I don't know what kind of use you're considering, but tri-axles can be a beeyich to back, especially on irregular or loose surfaces, because there's no telling which axle is going to bite and hold the ground.

In the long run, if one is prone to doing regular maintenance anyway, I'd opt for the two dually 10s over the three single 7s.

I have pulled both and the tandem-dual does "pull" harder than a trip-axle. The tandem has bigger brakes and bearings, no doubt. But the trip-axle has 3 sets of each (if you want 3 brake axles). So really the trip spreads the weight lengthwise and the dual spreads it more widthwise. Look at long livestock trailers, they have triples and i have seen some with four axles so the tires must stay on them well.

I plan to extend my trailer about 10 foot including a dovetail. I also plan to add a 3rd axle rather than upgrade. Currently I have 2 5200#/6000# (6 bolt hub) axles and 3 will put me in the 15k-18k range. I just bought 4 new rims, tires and brakes. Upgrading to 2, 7k would make that a loss.

If I were buying new, 2-7's would be all I need.

Have put lots of miles on both kinds; 32 ft cattle trailer was tri-axle; it pulled like a dream and never had any trouble with the wheels/tires. I bought it used and VERY cheap because one side of the front axle was twisted; took the better part of 2 days to get it straightened to my satisfaction. My 27 ft flatbed has dual tandems and it's what I'd want to carry a lot of weight. I guess it'd depend on your expected usage as to what I'd recommend..........

I have owned both 2 and 3 axle trailers and my current trailer is a 3 axle trailer with a 5th wheel. I haven't noticed excessive tire wear like I was told would happen on the 3 axle and as far as backing it up, no problems. That trailer hauls and tows like a dream.

I just took a 250 mile trip with it weighing 17,000 lbs over the mountains and it worked just fine.

I pull it with a 2006 Dodge dually which might account for the ease of pulling, but I really prefer this trailer over the tandem axle ones I have pulled in the past.
