Trailer tire question

[RJOL]

Rusty... You're right... I was looking at the 31 and 32 models... When they to to the 33 model, the "G" tire is standard. I've been looking at new 5th wheels in the 31-33' range...

Took a look at the manufacturer's site and that looks like a nice rig.

If you haven't checked out a Mobile Suites in person, I'd highly recommend taking the time to do so before you make a purchase decision. You get a lot of top-line content, features, functionality and quality for the money. We are tickled to death with ours, and we didn't just fall off the turnip truck regarding this RVing thing - this is our 3rd 5th wheel.

tires ?

No matter what tire you have it must be inflated to the max on the side wall on a trailer , a tri -axle trailer will have a weight transfer do to its inherent design when entering a fuel stop most have high drain area to go over as the front tires contact the angle and start up the load shifts to the remaining tires but most weight will be carried by the rear axle and tires a lever action takes place lifting the rear of the trailer and taking off the weight of the other tires and wheels . Some older MH with tag axles had many times where the MH got hung up on the tag axle as it was just a non power wheel ,but it showed that it raised the rear and took the load . If a tire is low on air it will heat and may blow out ,that could have happened. Tri axle equipped trailers scrub more and need more attention to inflation and ware , Thats why the makers of heavy trailers are starting to go with tandem duels in place of try axles to eliminate the lifting of the trailer and weight control with extra tire on the axles.

on all my stock/implement/utility/5er trailers if it comes with a 15" ST rated tire/wheel I trade them in for "16 LTrated wheel/tires. One big point I would like to make is in a trailer tire the sidewalls should not look like a basketball. A tire that has excessive side wall bulge such as the Marathons will have more sidewall cuts/brusing than a tire with a more straight up and down profile such as most 16" good LTs. My tire dealer, small farm/ranch town , will mount whatever you want but does not recommend ST tires on trailers that will be pulled in the pasture/construction site.

The Marathons are advertized as a ST tire with shallower tread depth and a narrow tread width which is not good for heavy trailers of any type.

The stiffer the sidewalls the better the tires can turn/slide around a cornor without belt damage or sidewall cuts/bruses from curbs/chugholes/rocks in pastures/construction sites.

Ok guys, Sorry to be off the board for a bit but I drive truck for a living and there is nothing I would like better than to get the strongest tire there is... . Hence the 19. 5" tire for the truck "F" rated 12 ply... .



You see here in a picture of the trailer. . the tires are pretty close together... I don't think a 235/85-16" tire would fit plus I would have to get new rims... .

I went to les Schwab and he saw there was a 225/75-15" "E" 10 ply Trailer tire... It is made by carlisle. about $97... .



On the Tires on RV NET that has had blow outs, are those the 10 ply or regular style?



heres a pics of the destruction... .



#ad




These rims are forged aluminum, the rim was on the ground but was running on the rubber edges... The rim was not even scratched on the edges. . wierd but great! don't have to get a new rim...



#ad




You see the Sheet metal above my left shoulder, that is about the only damage... There is not very much room for bigger tires between the treads... .



#ad




on the front being high, it is not noticable, on the level indicator on the side it is like 1" up and over 36' of trailer, I don't think there is like 200-300 # difference between the front tire and the back... . I have regular springs and the rockers to equalize...



sooooooo, any other suggestions?

This has been a good topic, along with these various threads I entirely agree.

I made the mistake a few years ago of having my old "93" CTD sitting too high in the back with too much inflation with my Air/Lift bags. Most surely I had a "rake" on the old truck due to too much air in the bags.

Hmmm, several years ago I had two blowouts out here going to Reno via Hwy 80. These tires blew out on both sides of my rear axle on Our Alpenlite 5vr trailer. Too much weight on the rear axle it turned out to be. These previous threads are accurate about an even trailer and max. inflation in any tire you use for trailer use. We have a very accurate logging of over 100,000 miles on this old "93" trailer now.



Our first two sets of tires were Good/Year radials resulting in poor mileage but no blow/outs.

The third set was Les/Schwab tires. These failures were on the old truck with the Air/Lifts. They were just on three years. On our present 04 CTD, all has been well so far as this truck sits level with the factory springs loaded.

As we keep our trailer in a storage yard, we keep the tires covered and on sheets of plywood. Sitting with the weight on these all the time is not good. Too be sure, whether the tires look good, We will change these every three years regardless. Inactivity is bad on tires.



Our damage was severe on the trailer when both of the rears went out at 200 mile intervals. It looked about like Eric's but on the left side. It is really something what a rotateing mass can do when it lets go in loseing a tire tread. .



Most of us do carry more weight than we are aware of. Its best to have your trailer axles weighed on a truck scale when loaded and abide by the GVW. listed on your trailer.

Its sure not fun breaking down by Baker Ca. or the area around Boron like discribed by the former threads in this topic. It does not always happen to the other guy, but this can be somewhat eliminated by the proper PM. By the way, we have got excellant service by the Les/Schwab shops, but they are mostly in the 7 western states here. They stand behind their product we have found. just my . 02 here.

Earlier post on problems with RVs

I made a post in March of this year about problems with RVs. Post on problems

Out of over 1,100 views there were only 15 responses and very few of them were related to tires. I have always contended that a major problem with RVs today and it is a safety issue is the type tires the manufacturers are putting on RVs. I still think the majority of manufacturers are placing tires that are at their carrying limit and there should not even be a question in the RV owners mind as to the capacity of tire to place on their RV. Plan as a pimple on your face. PUT the largest, most ply rated tire you can find on your RV that your rims will support. Tread depth and pretty design of tread is not an issue. It has been proven that tires designed for trailer service run cooler. Tires on an RV are not subject to the same type loading and road handling characterists as the driven vehicle is. Inflate your tires to the recommended pressures placed by the manufacturer not what is on the side of your RV.

OK, As I had stated before, ... and by the way, thanks to all the opinions and advice,...



My 3 axle is GVW for 15,500# The empty weight is like 11K...



The weight on the 3 axles via Cat scale is 12,000# (weighed all at once... . gonna do 1 axle at a time soon)



The weight on the side of the tire is 2580# @ 65 psi... "D" Rate 225/75-15" So that comes to just under the GVW of the trailer and I am lower than that when loaded up. (12000#)



So, 12000 / 6 tires is roughly 2000# per tire... . maybe a few hundred more for the rear tire if the weight is higher from being up a bit... . But doubt it... . So at 2000 or thereabouts, the tire should be OK with it even in hot weather... What I asked and haven't heard yet is if anyone knows the name "Mission" on the side of the tires? Are they just cheapie?



The tires I looked at in Les schwab was a trailer tire by a different name but made by Carlisle... It is a 225/75-15" 10 ply "E" tire in a 15"... . anybody heard of that or know if they are any good?



Gonna be doing these one tire at a time for the next few months or might just wait til next spring on most of them... . Once I start replacing them, I will do them all the same so I need to know what to get...

I got tired of blowing 15" D-rated tires and went to Denman 15" E-rated tires. We just got back from Alaska with 11,000 miles towing (many gravel stretches, frost heaves, and potholes) and no tire failures. My Brother in Law travlling with me, with same rig as mine, lost two E-rated tires before he bought a new set of E-rated tires in Anchorage. Since then, no failures on his rig.



I tow a 10,500# 5'ver.



I originally ordered Carlisle 15" E-rated tires, but they came in "Made in China" and I changed to Denman tires "Made in Mexico".



Go figure.....
