Why do the tires look like this?

[Right Touch]

do all dual axle trailers have this same problem where the tires look really weird when you are making turns? I was told by a not so reputable dealer that I have too much weight in there, that they are 7500lb axles and I should have 10,000lb axles on there and the axles are bending, but I only have a 52" exmark lazer, a 48" exmark viking walk behind, and a 36" Bobcat walk behind in there, along with the normal blowers, weed whackers and such. I've seen guys with much more weight in smaller trailers without this problem. I added it all up and doesnt come close to 7500lbs. The trailer is 8.5x20'. Could something else be going on here? By the way, I addressed this issue in another thread about what should I do to my trailers over the winter- thought the picture would be more helpful.

[DRM Ventures]

my dump trailer does the same thing

[punt66]

If its only doing it around corners then its likely normal. When your taking a corner with a dual axle trailer the axles are fighting with each other unlike a single axle. Your not overweight with what you have there.

[dnltractor]

it not the axles its sidewall flex on the tires , you probably have a car tire on their , get 8 ply or better trailer tires and that'll all but go away , they cost more but are better to run on a trailer , my tandem axle does it too , you ought to see when I make a sharp turn with the front end loader on the trailer , looks like its about to come off the rim ...the higher the ply rating the less sidewall flex

[Right Touch]

im sure it says it on the tire, but how do i know what "ply" they are?

[dnltractor]

are you nearby the trailer now , if you can go read the side wall of the tire it should say something like p205 70r15 and then have a section that says max pressure cold psi and then it should have the ply rating , most car tires are 4 ply and alot of trailer mfgs. put car tires on trailers when they sell them because trailer rated tires are 3 times the price of regular car tires

[Right Touch]

sorry i am not by the trailer now, we are getting a huge ice/snow/rain storm in jersey right now. I will check that tomorrow though. i was def shocked at the price the first time i bought tires for my trailer. Thanks for the info dnltractor

[DLAWNS]

Mine do that also. I've been told it's normal.

[dnltractor]

I think for your trailer you should have a minimum of load range e which is a tire that is about 10 ply and rated for 3500 lbs each

[dnltractor]

I think you probably have a pretty good ply tire on it though cause your flex aint nothing compared to mine

[Summit L & D]

You shouldn't be paying more than $100.00 per tire for 14 ply tires. We pay about $80.00 for all of ours. We get ours from tire shops that service mainly big rigs.

[nosparkplugs]

This is classic for single tire axle's, as the number of axles increase it gets worse. This flexing is worse backing up as the picture document. While trailering forward this does not happen as much.

A stronger tire will reduce flexing, but does not alleviate it. I pay around $150.00-$200.00 per axle for 2 tires

I have noticed a dual wheel axle does not have near the flexing

[dura to the max]

i would get another opinion from a reputable trailer dealer. there are no such things as 7500lb axles. most dual axle trailers have dual 3500lb axles, then they go up to 5000lb axles. its hard to tell from the pics, but most dual axle trailers let the axle flex like that when turning. you arent overloaded for the axle i would almost guarantee, but the tires may have too much weight on them.

[supercuts]

have you ever taken a high school physics class?? think about what forces are going on here. yes that should happen,think about it

[SiteSolutions]

Mine do that when loaded, load range E tires at about $110 each.

[J.A.G LAWNCARE]

looks good to me ,just keep the air in them and rotate them 2 to 3 times per year...

[Gravel Rat]

Have you ever seen a tridem axle 53 foot reefer van loaded with 30 tons of fish do a sharp turn on a dry pavement parking lot. You can hear the rubber peal off the tires it looks like some body has done a brake stand. The suspension is squeeking and squeeling. On a graveled parking lot rocks can shoot out from under the tires even on a paved parking lot.

A trailer axle will flex and so will the tires. You don't want 14ply tires or your limited to what speed you can run at. If you live in a area where the pavement can get hot enough to cook a egg a 15 inch or 16 inch tire in a 14 ply rating will over heat and explode :dizzy:

Radial tires will always have sidewall flex but ride the smoothest. A bias tire has less sidewall flex but rides rough.

[SiteSolutions]

Gravel Rat. You mystify me. You truly are unique.

1. Yeah, I've tried to turn a three-axle lowboy around in a cul-de-sac and that left a lot of rubber behind. Good times.

2. What on earth is wrong with 14 ply tires in their proper context? You get a tire rated to carry the load. I wouldn't run 14 plies on a big rig but on a smaller trailer what else can you use? Or are you suggesting using tires of fewer plies? Hard to understand if you are saying more or less plies are needed but then again, you didn't spell out which application you are talking about.

[Junior M]

You just now figured that out?;):confused:

my 8x20 enclosed has 2 7,500lb axles on it. They are torsion axles also. I run 10 ply trailer tires on it and don't have the problem with tires doing that nearly that bad.

[dura to the max]

sorry, i meant that there are no 2 axles that add up to 7500lbs.

[ovalracer44]

Its normal.

I have pulled tires off the wheel on my 3 axle race car trailer.

Do yourself a favor though, When parking do your best to not have the tires rolled over like that. A hot tire parked like that stands a better chance of separating. Definitely do not park it long term like that.

[ovalracer44]

my 8x20 enclosed has 2 7,500lb axles on it.

I really really doubt this. My 36 foot gooseneck car hauler has 3 5,000 axles on it, and its far heavier and built to carry more weight than a 20 footer.

No 20 foot enclosed will have over 5,000 axles on it.

2 7,500 axles would put you right at CDL weights in a 1 ton truck.

My 18' open has 2 5000lb

[ovalracer44]

That would mean you have a 24 foot trailer with a 15,000 GVWR. Not happening.

A 28 foot Haulmark has a 10,000 GVWR

How many lugs does your trailer have

A 7,500 lb axle will have 8 lugs

a 5000 lb axle will have 6
Less than 5000 will have 5

doesnt work that way. The gvwr isnt calculated by axles only. My 91 dodge has 1 ton axles in it. Still a 3/4.

[punt66]

All my trailers were bought and ordered new by me. I think i know what i ordered!!!!!!!!

[ovalracer44]

Go count the number of lugs on your trailer.

No enclosed trailer short of 40 foot will have 7,000lb axles under it.

[ovalracer44]

Take a photo of the tag. Its not possible.

No MFG would put more axle under the trailer than the chassis of the trailer can handle.

In fact, find a trailer with 7,500 axles underneath it with less than 8 lugs.

time to put your money where your mouth is.

First of all im not wasting a minute to prove to somebody on the internet what i own or ordered as a trailer or anything for that matter. The trailers have lifts in them and i ordered the trailers for the extra weight of the lift, tools and the second dragster up on the top.

If you were pulling that much weight, you are breaking the law doing it with a 3/4 ton dodge.

Straight from dexter axle.

and Carmate comes with 6,000lb axles

The difference between 2 6,000 axles and 2 7500 lb axles is 3,000 gross.

I ordered specalty trailers and axle upgrades and im sure im not the only one! There are plenty of them out there. I saw them every weekend at the tracks. Because you buy them off the lot as their made is why you get standard equipment.

By the way, I addressed this issue in another thread about what should I do to my trailers over the winter- thought the picture would be more helpful.

Do yourself a favor. Go to a moving company or a trucking firm that has a set of scales. Have them weight the total trailer weight with jack down and the trailer unhitched on the scale and then the load on each axle and trailer weight when hitched. Total cost will be about $40. Trailer GVWR should be 7500 or less. You have to count in the trailer weight too, which should be in the 2K range. That gives you about 5K to play with. If your axles show that both are at 3500lbs loaded with the jack down or truck is hitched, then the trailer is overloaded. If one axle is over 3750 and the other under, you need to balance the load better. Total load on both axles when you have the trailer hooked up to the truck should be at max 6750lbs. Tongue load of trailer should be at 10 to 15% but not over your hitch's rating.

Examples for a 7500 lb GVWR trailer.

Total weight unhitched <7500lb = ok
Axle 1 = 3375, Axle 2 = 3375, tongue load = 750 = ok
Axle 1 = 3575, Axle 2 = 3575, tongue load = 350 = not ok
Axle 1 = 2975, Axle 2 = 3775, tongue load = 750 = not ok and needs checked for binding in the spring rigging

If your truck hitch is rated a 5K/600lb tongue load, then your trailer weight needs reduced or you need equalizers on the hitch to get it within the load leveling rating.

According to the trailer maker of our trailer, the tires should be just about gone by now. But they still have little wear after almost 10K miles of use.
And no, I've never seen the tires/axles in the condition yours are in even under extreme cornering on our 6'X16' tandem axle as I keep the axle/tire ratings/loadings inline.

[SiteSolutions]

Mine look worse when they are low in air. Maybe make sure you have them aired up to the number on the sidewall? Mine take 80 psi, and that is where I like to keep them... although in this business, lots of little nails conspire to make sure that sometimes one or more tires is lacking full pressure.

Ok now that I see there is a company that puts them on enclosed trailers.

Lest we tie this into the original topic.

OP has a trailer used for lawn purposes. Loaded no where near the max, on what is most definitely not anything more that 3,500 lb axles, and he is told that tire deflection is because he needs stronger axles.

Hmmmm...

sorry, i meant that there are no 2 axles that add up to 7500lbs.

There are 3750 lb rated axles out there. And they overload some tires for that rating. ST 205/75-15 6-ply rated tires are only good for 1820lbs each. Need to use either a higher ply count to get a higher rating, a different makers tires at a higher rating, or a wider tire with a higher rating to get full use of those axles.

It's a misprint! Don't you know that there isn't a enclosed out there with 7K axles????

Mine has 8 lugs on each wheel and brakes on every wheel. It has a 2 5/16 ball. The gvw is 12K. So with my 9900 gvw truck and 12K trailer I am still under 22Kgcvw so I am good unless I cross state lines. Most cops aren't going to mess with a short enclosed trailer and pickup about weight limits because they know they would be wasting their time.

My trailer is much heavier than I need but I got a steal on it and I don't think I could have bought a light duty 12' enclosed for what I gave for it. The nice thing about it is after 8 or 9 years of dragging it every day there is very little wear and tear with such a light load in a heavy trailer.

Yea thats exactly why i buy them heavy. They last. They arnt stressed. You can lead a horse to water.

:clapping: Yep! There are all sorts of different axles out there if you look for them. And take a look at couplers also. Our trailer has a 10K/1K tongue load hitch on a 7K trailer. You get what you order if you don't take an off the shelf trailer from a dealer.

OK we were talking about Enclosed trailers.

I was wrong here. I had never known anyone to get 7,000 axles on a 20 something foot trailer. Its pretty useless if you ask me.

I guess if people want to use up the more expensive 16 inch tires they can have at it.

3,500lb trailer + 2-1,000lb Walkers + 2,000lb of wet green grass + 1,000lb of misc handheld and push mower, etc = 8,500lb. The 7Kgvw trailer would be overloaded!

1,500 lbs would be on the tongue. Subtract tongue weight from the total weight and thats how much your axles should be rated for.

Sorry, but you are wrong. Tongue weight is your safety factor and if your trailer weighs more than the axle rating, fine time if stopped. Read the tag on the trailer. It will say the GVWR of the trailer is the same or less than the combined axle ratings. Weight on the tongue is counted against the total trailer weight.:rolleyes:

Their talking about axle capacity. Weight distribution. Not the GVWR.

[bobbyr]

your trailer most likely has a torflex axle insted of a spring suspention for some reason that type of tire and wheel roll show up more on a torflex than a spring ride i beleave it is because of the off set spindle it is normal for them to do that and the more weight in the trailer the more you will notice it but they are a great axle and i would not worry about it but they are right on the tire comment their are a lot of trailers out their that do not have the wright load rating and it always catches up some time

[justanotherlawnguy]

does the trailer have drop axles? mine does and that could be a bent axle from clipping curbs. i have had to replace both of mine. does the inside of the tires wear out faster? if so you got yourself a bent axle..

like mentioned earlier those 5 lug wheels are 3500lb axles
