New rig, tire shread

[214skier]

Brought brand new 367FL home last week. Headed out over the mountain pass to eastern Washington last night on our first trip. We had a tire completely fail coming just over Steven's Pass last night.

As some of you may know, we have had a chronic fish-tail problem since leaving the dealership. As quick summary--yes, we are high (by 2") in the front. We attempted to lower the hitch point to bring the rig level; however, it has caused the over hang to connect with the truck bed.

We naively assumed we could operate the LIpert electric jacks like our former hydraulic jacks--but could not figure out how to independently operate to lift the rig. The Ford F350 jack was not strong enough to lift the rig--so we called for road side assistance.

I don't know if we have axle problems--but we are taking the rig to the tire center today and replacing all four tires with something with greater substance. Open to any and all advice here.

You got lucky at least that it doesn’t appear you suffered any damage to the rig. If it were me, I’d find a Les Schwab tire center and have them install a set of Sailuns on your rig. I see you have 8 lug wheels, so you may be able to run them at 110 psi, but if not, run them at the highest pressure the wheels allow. If you are able to run 110 psi, you will need metal valve stems. I would also get the 285/85R16 which is a little taller than the 285/80R16 so you will gain a little more height to help with the tail dragging low.

Ditto. Sailun 285/85/16

Update: Sailun tires ordered at Les Schwab, rig goes up at 3pm today to be installed.

Having Les Schwab check all U-Bolts and activation of suspension to ensure everything in working order regarding "fish-tail" issues.

When they check the torque of the nuts on the U-bolts, make sure the rig is down with the weight on the tires and the springs fully supporting the rig. When the springs were attached to the axles by Dexter, they were torqued with the springs curved like when unloaded. Once the trailer weight is on the springs and they are straightened out, the nuts will be loose, and for some reason, the Montana plant does not check the torque on the nuts. Have them torque the nuts to 70 ft lbs.

IMO changing tires is not going to solve the problem. Your OE tires have/had plenty of reserves if properly inflated to the placard recommendations.

Whoever installed the hitch should have informed you they couldn't balance the trailer correctly. Make them fix it.

NOTE: If you're convinced the failed tire was the problem, save it and file a NHTSA report. There is enough of it left for them to pinpoint the cause of the failure.

It looks like you dodged a bullet by not having any damage to your rv. Be sure you buy g-rated tires and if they are available i would buy the Sailun 235x85x16 tires. This will raise the rv 1/2'' if you have the 235x80x16 tires and you certainly need a little extra height at the axles. If your tire dealer doesn't have the Sailun tires then you could order them from Simple tire and have them delivered to your dealer. I am sure there are other good G-rated tires out there but the Sailun tires are by far the most popular out there at a reasonable price. Good luck.

Good advice. Our consultant at Les Schwab recommends the same thing.

From what little I can see of the tread, it doesn't appear to have unusual wear. Do you have a TPMS? If not, it is very possible (likely?) that you picked up a nail/screw/etc and had a leak in the tire and ran the low tire until it came apart.

I arrived at a site years ago to find a rear tire on my truck low (no TPMS on that truck). Aired it up with a portable compressor and took to shop. Had a steel rod about 1/4" diameter and about 8' long stuck in the tire! Many more miles and that one would have come apart.

I just inspected the tire in daylight. There is NO screw or nail in the tread. The tires are brand new (as the rig is too). This is our first trip.

Even if not a nail this time, I would still recommend a TPMS. Even new tires can pick up a nail. And valve stems sometimes leak. Might save you another similar occurrence.

That tire just has the look of a run flat rather than a blowout.

These are a must have, so much peace of mind. Second year with one and will never tow without one again. If I might add... when buying a TPMS get the flow through sensors, they are so much easier to adjust pressure through than ones you have to remove.

Not sure from the looks of tire that the failure point evidence would still be there - IMHO - Good Luck on finding answers. Ditto going to 85 vs 80 size Sailun mentioned above.

Thank you for all the great advice here--we will take all of it.

Yes, I plan to do all the work / investigation to the trailer and its issues independent of the dealer / Keystone. I will not loose camping time to have the rig sit. We already spent an additional day at the dealer (they are located 5 hours from our home) and they could not determine the issue.

Yes, a friend of mine is a forensic engineer who specializes in tire issues. So, yes, I will be strongly supported in my discussions with the dealer / manufacturer.

Having said that, my view is no different than if the refrigerator fails--the tires are failing and should receive some compensation or replacement value for that fail. Not sure why tires delaminating after less than 600 miles of usage would be treated different than a piece of molding that might all off.

Good advice on the tires. I would be looking at how the fishtailing and the blown tire are connected. Look at all the suspension components for proper actuation. U bolts are known to be loose from the factory. Anything loose can cause grief. Keep chipping away you'll figure it out.

I second, or third, the TPMS add! My son-in-law had a blowout that shredded and we were laying under his travel trailer at the campground trying to reattach enough wires for him to have AC and lights in the dark. I purchased for my rig before our next trip and the peace of mind is WONDERFUL!!

[RMcNeal]

I agree on the Sailuns and the TPMS. Just curious...Was the wheel hot at all? Could there have been little to no grease in the bearings? I have heard of that happening before and causing a blowout from the heat. Just wondering out loud.

[mazboy]

first question, are these G rated tires? if so were you running them at 100-110psi? the pic seems to show that they are not G614 GY. Saliun maybe?



as for the fishtail, that is a new one on me?

[sourdough]

Skier, can the folks at the tire store look at that tire and maybe get a feel for the cause of failure?

Your issue is odd to me, and I think the new tires may very well remedy the situation (I hope), but I had an issue once that this reminds me of. It was not with a trailer but I did buy a new car (back in 90) with Firestone tires on it. Within the first several months I had to replace them all due to the outer tread carcass separating from the inner tire...it was unbelievable. A tire shop pulled one of them and the tread would just literally move around on the tire....and it did cause some funky feeling driving. Doubt that is your issue but might be something to look into. It if was it might ease your mind about the other issues. After losing an OEM tire in short order on another trailer I don't trust any of them.

M HC arrive with Rainier LR F tires. If it were a G rated it would more likely be a GY G614 as they don't have near as good reputation of the Sailun
