RE: leveling...1 or 2 tires?
I use a couple of 2x's under one tire if it raises the trailer enough or if the trailer needs to go higher than 3"-4" I go with boards under both tires.

RE: Shortest 5th wheel or 5th wheel toy hauler
Check out these folks ALLEN. There a small outfit and have been around since the '60s.
They show 5th wheels starting at 19'.

RE: Help --- Looking for a bottle jack
I have a old '70s 12 ton shortie hyd bottle jack. It was sold as a truckers special as it came with a 12" x 12" wide base for using on soft surfaces on the side of the road. Its great for sliding under the axles to lift the axle when changing a flat tire.
Lifting one side of the trailer is no problems with this jack.
IMO a 4000 lb jack is simply not he best tool for your 16000 lb trailer when lifting the end of one axle or other jobs that require lifting the side of the trailer.

RE: Should Tire Max Load = Trailer GVWR???
Disagree with the guessing part. If the unit hasn't been weighed its just a guess as to actual tire/wheel capacity requirements. Weve seen to many trailer owners in the past come from the factory with pitiful undersized axles/wheels/tires. Mounting tires per the GAWR wouldn't be the smart idea.
Then on the flip side;
If the axles are 6k and the axle loads are scaled at 10900-11500 lbs wet and the trailer has a 14.5k - 15.5 GVWR then mounting tires at GVWR may require a unnecessary upgrade to higher rated wheels/tires. We see this just about weekly on the TH and 5th wheel forums on this and other trailering type webs. Some folks with 11000 lbs on the axle/tires have gone on up to 17.5" wheels and tires to match the trailer high 15k GVWR and to get away from 16" ST tire issues.
Know your vehicles actual scaled axle weights is the best safety policy.

RE: Should Tire Max Load = Trailer GVWR???
The advantage of a E tire over the D tire is at those higher pressures. I doub't your 15" steel wheels are 80 psi rated.
HOWEVER some 15" x 6.5" wide trailer wheels that come with ST225/75-15 D are pressure rated to 70-75 psi. Yours may be.
Many trailers come no where near their GVWR. Some are at or over their GVWR so there is no black and white answer to your GVWR question.
As jauguston says it depends on the actual loads on the axle/tires and if you want any or need a certain reserve capacity. I wouldn't guess or estimate axle loads.

RE: Good weekend but had a blow out.
I'm guessing your tripple axle has 6k axles = 18000 lbs of capacity.
I would go with a LT235/85-16 E tire rated at 3042 capacity if you have room as they are 31.7" tall. Or a LT245/75-16 E at the same capacity and is 30.4" tall. Six will give you 18252 lbs of capacity. Be sure and go with a LT tire that is recommended for use on a heavy trailer.
I traded with Robertson tires or Hibdon or Sams Club or Claremore tire store. I've even ordered LT tires through Walmart and let them mount them or use a small tire shop of my choice.

RE: help me determine the age of my tires
Continential Vanco 2 tires are very popular with trailering public including RVers. They show a 205/65R-15 C load range at 1874 lbs capacity. These tires are a LT design and used on vans and trucks.
If your thinking about a wheel upgrade there are a few more 15" LT tires that require a 6" or 6.5" wide wheel with pressures up to 65 psi. Don't bite into the using higher pressure tires than the wheel is rated for then derating the tire with lower pressures for a tire on a trailer.

RE: help me determine the age of my tires
looks like I need to getting some new tires before taking any long trips. I called around a few places this morning. Most have either Carlise or Greenball tires. This trailer has 5 lug 15" rims so LT tires are out.
Maybe we can help you. Give us the tire size and load range. There are a few 15" LT sizes available for trailer service.

RE: truck tag
In Oklahoma we have no weighted tags to purchase or a registered weight of any type for a private use truck.
However Oklahoma does have a requirement for trucks in commercial service (all sizes) to be registered at a GVW for a gross weight or for a gross combined weight.

RE: whats your career?
Retired journeyman aircraft tool builder ... hard and soft.
Very satisfying job/duties/responsibilities with lots of work buddies that I worked with in the same profession for 39 years in several different aircraft manufacturing plants. Sure do miss them.
'Course aircraft tooling is what it is and with lots of feast and famine time I had lots of spare time doing other things. Tried operating my own sub contract construction outfit part and full time for over 11 years. Too much time on the road away from home moving materials (steel) and work equipment to the next multi state jobsites. Sold it to one of my subs.
Which I could have retired first.

RE: Wheel balance?
Sounds like the dealer is honest and has been in the tire business for quite a while and may understand the reasons its not necessary on a trailer. However its your money so if you feel its necessary I would have it done.
Some folks brag on getting thousands of miles of trouble free milage out of the OEM tires that wern't balanced then swear up and down that tires on a trailer should be balanced.

RE: Biggest New 5er behind my '06 Dodge 2500?
I currently own a '06 Montana 32' with two slides and we are looking to buy a 4-slide 5er without having to give up our Dodge Ram 2500 which has no issues pulling my current 5er. I love Montana and I'm considering the option of the High Country but I have not shopped in 6 years. I know manu's are making lighter units. Any advice for a size upgrade from any manufacturer with-out changing tow vehicle? This upgrade could be retirement traveling condo in 6 yearss:)
A 5er with four slides on a 2500 truck will takes some legwork finding one with a light pin weight.
One of my trucks is a 2500 Dodge/Cummins 2wd quad cab NV5600. Were limited by those small 6000 RAWR/tire and wheel capacities so anything over a 2500-2700 lb wet road ready pin weight will overload the OEM tires. You will need to be looking at a 4 slide unit with a 2100-2200 lb dry pin weight.
The 2500 Dodge is the same truck as the 3500 SRW since '03. However the Dodge SRW is a sick pig for carrying capacity with it pathetic 6200 RAWR. Ford and GM SRW are at 7000 and 7050 RAWR respectivly.

RE: Ok here we go
My state as many states, don't have a paid tag requirement or any registered weight requirement for private use trucks (any size). A out of state one ton dually may have a 15k-20k registration however it doesn't get the operator anything. All the leo is interested in the loads on the trucks don't exceed the "lessor" of the vehicle manufacturers axle rating or tire load ratings.
He isn't interested in the trucks GVWR although its on the placard. And he isn't interested in a GCWR as it simply isn't on the truck or a placard nor is it required to be per the FMVSS's.
As the CA weight reg Rick posted pointing to the vehicles tire load ratings per the FMVSS, were simply allowed the sum of the vehicle manufacturers axle/tire rating. Remember the FMVSS says the tire load rating shall meet or exceed the vehicle manufacturers GAWR.

RE: Ok here we go
"The GVWR figures are neither guidelines nor estimates; they are limits, and there are numerous valid reasons the manufacturer arrived at these figures. If you think the figures are "close enough" or have a fudge-factor percentage built in, think again. Your Warranty coverage and your safety, may be at risk"
So sayeth Trailer Life Magazine's 2012 Guide to Towing in an article entitled: "Choose Wisely" (see pages 6 thru 9). Something to think about. :C
Just something to think about.......
Why do they call it Gross Vehicle Weight RATING, and not Gross Vehicle Weight LIMIT?
It would seem if the GVWR was the max they would call it GVWL....... Yes, no, maybe?
Good point.
Thats one reason legal load limits on a trucks axles/tires don't get into the vehicles GVWR.
Look at the '12 F350 SRW 6.7 diesel truck. Ford Fleet service website, for whatever reason, has 13 different GVWR ratings from 10000 lbs up to 11500 lbs. Major differences in the packages is 2wd/4wd and higher rated 18"-20" wheels and tires vs lower rated 17" wheels and tires.
Even the F250 has a 10000 lb GVWR however its limited by the lower rated 6100 RAWR spring pack.

RE: Help! 245/75/16 on 16x6.5 trailer wheel???
Hmmm , odd pressure rating for a LT245/75 tire.
E load range = 80 psi
F load range = 90 psi
G load range = 110 psi
Are the LT245/75-16 a radial or a bias ply tire and what is the brand and load range ??

RE: One more tire question
I have been looking and I find a lot of choices in the 265/75/16 size tire which size is very close to the ST 235/80/16 that are on my trailer. Many have a load rating of 123(3417#). I don't see people using this size tire as an alternative and am wondering why? All of the experts please enlighten me.
looks like some have turned your thread into a ST vs LT.
I would advise anyone thats going to use wide base tires on a trailer to first contact the trailer and the axle manufacturers.
The reasons are many but one reason we don't see wide base tires like the 265/75 series tires on trailers is because their very hard on the trailers suspension parts especially the U bolts/spring keepers/wheels/spring hangers/etc as it slides sideways around cornors. Even the tire itself is put under tremendous stress as it slides sideways. More so than the 235/85. Other factors are much more parasitic drag VS the narrow 235/85 tire.
Load carrying tires work best with the wheel width is same as the tires tread width. This is critical for getting the best long term preformance/reliability out of the tire.
I sure wouldn't put a 8" - 8.5" wide tread tire like the 265 on a narrow 7" trailer wheel. That size tire needs a 8" min wide zero offset wheel.
We are talking about tires and wheels for our "trailers".

RE: Million Mile Chevy Duramax LBZ
Good for GM.
I've got over 800k miles towing for a living off and on in the late '60s to the early '80s. However that 800k had several different one ton 454/460 DRW trucks mostly GM and two Fords carburated gas hogs. 4 to 6 mpgs on average with 2000-2500 mile oil changes. These truck towed from 25000 to 32000 GCW on every run and had a life expectancy of 120k to 175k miles on average. Having something back then like the DMAX would have been fantastic.
There have been several Dodge/Cummins work trucks reach the million mile mark after 6-8 years of working. IMO we'll see more GM LDTs in the million mile work truck club now that GM raised their GVWRs and GAWR to compete against Ford and Dodge in the LDT market.

RE: Thoughts on eternabond tape

IMO Eternabond isn't the best choice for that type of job. If you have a new unit I would contact the dealer or manufacture for their input as other have found out the hard way its not the best idea as one RV.net member found out:

A while back, I opened a thread asking whether eterna-bonding the roof seams on an almost-new TT as a preventative measure was a good idea ...the virtually unanimous opinion was 'yes'....
Well, took the TT to the selling dealer today for some minor work...rep. sees the tape job, asks 'why on earth did you DO that'?, and tells me that: a.) it's not necessary b.) it'll trap water if any water ever gets beneath the tape, and c.) any claim under the roof warranty may get kicked on grounds that the roof has been 'modified'....
thought i did the right thing by sealing the seams, but now not so sure....

RE: Do I need a bigger Truck
We have a 2011 F250, SRW, 3.55 rw axle, Long bed, 18K Reese hitch and air springs added after market.
Looking at Fords Fleet service web shows the difference in a F350 SRW 7000 RAWR and the F250 with a 6100 RAWR is higher rated rear axle springs/wheels and tires. Front axles/frame/engine/tranny and the rear axle itself
Ford fleet service guide for the F350 SRW shows up to 3800-4000 lb payload depending on the trucks configuration. Add Fords uprated F350 SRW 18"-20" wheels and tires and air bags or other suspension help or springs from a SRW , and your F250 truck has the same ability to carry the same payloads. No, I didn't say it becomes a F350 SRW. Just the same weight carrying ability.
Or upgrade to a F350 SRW or even the DRW. Your choices.

RE: Ok here we go
RV.net is is a poor website to find out about "legal" weight issues. There are many LTL type haulers websites for finding out what legal weight issues are and it sure isn't what some on this web push as being legal. Weight threads on RV.net are a good sourse of jokes.
Anyhow the 1500HD is not your typical std duty 1/2 ton truck.
It comes with a 8600 GVWR/6000 lb RAWR which is a 14 bolt corporate 9.5" gear/E tires and wheels/6.0 engine with the 4L80 tranny. For all facts and purposes its the old std duty 2500 truck of years past.
The 1500HD has a 4500 lb front axle and 4500 lb front suspension.
The 1500HD has a 6000 lb rear axle and rear suspension/brakes/etc.
The 1500HD will have a rear axle payload of around 3500 lbs depending on actual scaled weights and how the owners has his truck loaded.
MMarty, the numbers your using like 7869 or 1073 pin are manufacture dry weight numbers. Im guessing the trailer after you load it will be around 9000-9500 lbs and a wet pin weight of around 1800 lbs.
The truck will carry the 5ers pin weight with no issues. The 6.0 smallblock will pull that kind of weight although nothing like the Cummins.
IMO the 8.1 GM or the V-10 Ford in a 2500 would be a better choice from a performance standpoint. Both those engines are towing beasts.
You sure don't need a dually for that size trailer.
