tire issues on the?

[bp_mp_tx]

Would appreciate folks who have dealt with this issue weighing in. I would like to look at toy haulers for possible full-time. Love the extra room/screened room/storage. My DH says "no". His problem? Loves everything about them but the size we'd be considering would have 3 axles. He thinks that would be a problem with the middle tire pivoting instead of going straight forward or backward. Tires aren't made to go sideways. Comments?

The front axle tires and the rear axle tires are the ones that slide sideways (side scrub) as the trailer goes around a corner or backing much of the time. Which tires side scrub more can depend on terrain/a level trailer/etc.

Interesting, and makes sense now that you brought that to my attention. Thanks for explaining that Jim, you obviously have a lot of experience with these triple axle beasts.

You're right, that middle tire IS the pivot point in very very tight turns like you can do with a goose neck so your truck can get big angle with the trailer and pretty much force it to pivot in a PIROUETTE scrubbing the front and rear tires the most.

You know, I've never had a reason to pirouette my 41' TH around, not sure a bumper pull could turn as tight as a goose neck, but suppose it could come in handy though.

More I think about tire scrub the more I'm leaning towards all tires scrub, thats their job really, yes..?

When you initiate high speed turns in any vehicle, your front tires turn in and depending on how hard you hug a corner, there is a lot of tire scrub and heat. For that matter, the front tires are almost always scrubbing to some extent, much more whenever turning hard at high speed.

Granted, when doing the slow speed JIMNLIN PIROUETTE, a lot of low speed scrubbing occurs, but the pirouette is not a normal every day operation for most. I've never done a triple axle pirouette. Think I'll try that on the grass real soon...lol.

In my mind a tire is designed to scrub, thats a big part of its job, hanging(scrubbing) corners, right..? Some tires do it better than others...
So I ask, what is too much scrubbing, does normal every day towing a triple cause too much scrub...?

With all due respect to your husband, tire scrub on the middle tire being an excuse is just silly. Its so minimal.

It reminds me of people who cancel a camping vacation because gas prices go up. Because they have to spend an extra $50-$100, they cancel an entire trip. Your tires will easily last tens of thousands of miles and more if properly maintained.

Another thought about triple axle trailers is the stability when parked. We have a 43' Raptor with trip axle and 6 point stabilizers. We were in a storm in Okla with 65mph side wind and couldn't feel any movement. We haven't had to replace tires yet cuz we have only owned the Beast for a year. Will I dread paying the money for 6 new upgraded tires, sure. But the stability when FT'ing it can't be beat.

[JIMNLIN]

good point on the better handling.
Having owned several of both IMO the tri axle with 6 brakes was hands down superior braking at full loads over any tandem axle unit.

I have a triple axle fiver and I can tell you from my own experience it tows better with more stability than any two axle trailer I have ever had, with good tires ,have never had a tire problem, had lots of tire problems until I started using good ties, Goodyear G614, Salin 637's.

Thank you for feedback. DH won't budge, so I guess it will be a regular 5th wheel if we make a change.

Most tri axle trailers I used to make a living had 5.2k axles or 6.k axle and a couple with 7k axles.
The Michelin XPS Rib or the Bridgestone R-250 both are a commercial grade all steel ply carcass tire in a LT235/85-16 E at 3042 lbs capacity work great on the 5k-6k axles.
I have one 36' tri axle GN stock trailer left with 7k axles. I just had 6 Sailun S637 commercial class tire with a all steel carcass in a 235/85-16 G at 3750 lb capacity put on this trailer. With my short bed Dodge/Cummins I can spin the fully loaded triaxle trailer 360 on the center axle on pavement or green grass.

On my triple axle, have never had a problem with any position tire after going to Michelin LT Ribs.

Before going to LT's, didn't matter what position the tire was on the trailer. All position ST tires would fail on my triple axle, regardless of tire position.

I don't see any difference in my LT Ribs wear comparing my middle tire to the front or rear tire on my TH. They all seem to wear the same (very little), and tow smooth and steady all the time...

Think the key here is, if you use the best grade tires, should not have any problems with a big triple.

With my bumper pull triple I don't think I can make as tight a turn as a 5th wheel. In fact I can't(or don't) turn sharp enough to cause my middle tire to be the pivot point. The trailer will always be moving a little forward or backward while turning. Thus preventing the middle tire from being in an extreme pivot point non rolling scrub only position.
I am far from a expert on this, but this has been my experience.

Our 43' TH has two heavier duty axles which is part of what attracted us to it. We full time and have put on 9,000 miles since we left "home" last August. It has 17.5" H rated tires.

Only real problem with 3 axles is 6 tires are 50% more than 4.

Yes it's an issue, but you learn to take wider corners as you drive. The reality is that triple axle owners haven't reported major problems over the years. It can cause some premature tire wear, but I can't say I've seen frequent posts about issues from it.

[TexasRangerRzR]

Yes, you get increased tire scrub with a triple axle trailer. I have learned to try to not turn as tight whenever possible.
