Much to my wallets dismay, I just popped for 4 new Michelin
235/85R16 XPS Ribs. $1064.00 out the door price from my local Ford Dealer.
After talking to several people at the rally and seeing the damage done to one Bighorn I decided to make the move and have some peice of mind.

Looks like I will have to replace my tires also; however, they are the original Karrier Loadstars with 14,000 miles and the replacement need does not seem to be a tire issue. After returning from the Rally I noticed that on my off door side the front tire has worn significantly on the inside and the rear tire has worn on the outside (both wear patterns from the last groove outward). On the door side, both the tires look great with no signs of any significant wear. I'm not sure what caused this; if its a toe-in toe-out problem; an alignment problem or what; however, it certainly is not a result of the tires (more commonly referred to as China Bombs). Any advice or suggestions would be greatly appreciated.

Well, I just sprung for 5 Goodyear G rated 614's to replace my E rated Mission Tires which had 13,000 miles but I am on the 12th day of a 51 day summer trip. I was twisting and turning whether to buy the Michelin E rated XPS 10 ply 80 lb PSI Tires or the Goodyears which are 14 ply. I was lucky enough to have the choice with my 16" aluminum rims that had G 3750 lbs stamped on the inside.
As an objective Bighorn owner, I am incredibly amazed how smooth the ride is with my 110lb PSI tires. Hardly any chucks and bounces, while I caravaned behind Bighorns equipped with the E rated tires bouncing and swaying, chucking and jiving from Canyonville, to Winchester Bay. I paid $1346 out the door less $125 in rebates, mounted, balanced with steel nutted stems and taped weights.
The difference in the ride is enourmous. I can understand buying those excellent Michelin's, but the G rated 614's tires are like nite and day. Thank you senior RV savvy campers who insisted I buy the Goodyears. I am smiling ear to ear after driving 1,000 miles and sometimes forgetting I am pulling a heavy rig. My mission E rated tires cost me severe back problems and now I am singing the praises of the famous Goodyear 614's. To me the choice after driving mountainous, curvy roads and having zero problems is clear as a bell.

Vangoes - I have been there with the tire wear problem like you have. After fooling around with the dealer who didn't have a clue about aligning trailer axles I took my unit to a shop that aligns heavy trucks and trailers. They fixed the alignment problem in two days. I don't think that most RV dealers have niether the equipment or the know how to align these axles properly. Trust me on this one, I spent a year and a lot of money in tires trying to cure the problem.

Safe travels to all,

Hello, Put us on the list for tire problems and damage. I am also looking to purchase different tires. I noticed that you bought 235/85R16, is that the orginal size that was on your trailer?
We have ST235/80R16 on our 2008 3055 RL Bighorn and have had nothing but problems.
We would love it if we could go with Michelin tires but we talked to Heartland and they told us we could not use the 85's. Any info you can share would be appriciated.

Hello, We want to replace our China Bombs and are trying to understand what tire we can replace them with. The tire now on the trailer are ST235/80R16. I looked up the Goodyear G 614 and see that they are 235/85R16. I talked to Heartland and a couple of tire company's and they did not recommend that we go with the 85's as they said they were larger. When we ordered our 3055RL Bighorn we did get the aluminum rims but we don't know if they have the same rating as yours. Any information you can share would be greatly appreciated .

I just put on Michelin 265/75/16 on mine. They are a load range E w/ 3415 lbs.

They are 1" taller than the 235/80/16 and 1" wider. I did remove my shocks and upper shock bracket for clearence. Easy trade off.



Either way, the Michelin or 614 Goodyear, two of the best tires on the road today for our use. Well worth whatever you have to do to get them under your trailer.

Hi D&J,

I have an 08 3055RL Bighorn and replaced my Missions with Michelin ST235/85R16 E rated XPS. It did decrease the distance between my tires to about 1 1/2" or 2". But I have just gotten back from the Heartland National Rally, a trip of just over 4000 miles for us, because we took the long way back home. Total mileage since replacing the tires is about 7K or so. I have not had a problem, the tires do not hit the shocks or rub on the frame.

I am happy with my choice.

Hey Jim,
You probably do have better clearence with the 235/85/16. The XPS is a great tire.

I went with the LTX which forced the 265/75/16. I now have 10 tires, all the same between the trailer and the truck.

Think of the possibilities:D

jimtoo
07-06-2009, 08:43 PM
Yep,,, SouthernNights,

I was thinking, for a change, because I have the same XPS 235-85R16E on my truck.:D

I am a huge fan of Michelin tires, have them on the truck and car. I have GY 614,s on the trailer because Michelin doesn't make G rated tires, I heard at the tire store they might start making them in the future.

I have the Michelin XPS Ribs on my Bighorn 3400RE. Changed them out as soon as I rolled out of the dealership. I have used Michelin tires for years and have never had a problem. I asked the tire guy at the Goshen Rally about the Aluminum rims on my 3400. He said if I had the 7spoke rims with no split in the spoke it should be a good rim. I checked my spare and on the inside there is a stamp indicating the max load of the rim. Mine has 3750 stamped on the inside. They are G rated rims. I am very close to the weight limit of the XPS Ribs.. So.. I plan to put 614's on by next year.

Rather be safe than sorry...

Check Sam's Club for those G614 RSTs, I was able to order them special for $1001.03 which include installation and road hazard warranty!

Bill you are correct that Michelin does not make a G rated tire in the XPS for auto. use, but if you are looking for a higher rated tire, check out the LTX line. The reason I went with the LTX is the load capacity-3415 on the 265/75/16. The footprint of this tire is HUGE.
It is still rated at LR E. Not sure why.
The only disadvatage if there is one, is the LTX is open shoulder tire. They may require rotation a little more than a closed shoulder in this application.

Traveling back from Cape May, NJ we lost one of our Mission Tires (large chunks of tread peeled off). Thank goodnes the tire held up and we were able to pull off to change it. Just replaced all five with the GY G614RST - $1385 was my price balanced, mounted, filled with nitrogen, and HP stems put in. I had about 7,000 miles on the origional Mission when that happened.

Just a follow up on the new Michelins.

Our BC always pulled great, but with the addition of the Michelins it is even better. The trailer did feel a little top heavy in cross winds with the Mission tires. We came out to the coast yesterday in a series of strong thunderstorms and were lucky enough:rolleyes: to be in some strong crosswinds again. Very stable. I was glad we upgraded.

For any one considering changing from the Missions, the Michelins are a great investment. I have no personal experience with the Goodyears on small vehicles, but they have a great reputation in the trucking industry. I am sure either tire would give you good service over the long haul.

Hey Jimtoo, is the switch from 235/80 R16 to the 235/85 R16 still working out for you? I would like to do the same; currently there is 2&5/8 inches between my tires, and I'm wondering if I will have room to make the same choice you made.

Has anyone else made this change?

Kakampers and Vangoes.

Since you were both at the Goshen rally, were your axles checked there for alignment? They checked my alignment, even though my units was only three weeks old at the time.

Just a thought.

Boca,
Lippert did check my suspension for the Lippert components, but as I have Mor Ryde they did not check those components nor the alignment.

Hi Sthramann, Yes it is working OK for me. I have aprox 1 3/4" between the tires and have no evidence of rubbing on shocks or anything. Just completed a 4100 mile trip and not a problem. Have towed aprox 8000 miles since installed.

My 08 Bighorn had the 235/80/16 tires from the factory.
The 235/85/16 Michelin fit just fine.
The factory also told me I couldn't put the Goodyear G614's on .
When we took the wheels off to mount the Michelins the rims are stamped for
110# tires. Sounds like someone at Heartland didn't do thier homework.

I had replaced the Karrier tires on my 3400 RL after all 5 went bad 1 or 2 at a time + one of the new replaced ones. Unfortunately not before having major damage when 2 blew out. Found a good used set of Goodyear 614's that were, by date code 10-14 months old. Still looked almost new. Lucky to find them on a Sunday afternoon in Kingman, AZ. I have since traded for 2010 3410RE and took off my G's & put E's back on it for trade. I had 7K axles installed and it has Freestar G's on it. Has anyone had any issues with these tires? Would I be miles ahead to put the used Goodyears on and keep the Freestars for spares or sell possibly sell them while they still are new? Don't want another large repair bill and downtime when I'm on a run with a time deadline.

My original Mission Tires were E rated 235/80/R16's, and my new Goodyear G614's are 235/85/R16's and they fit just fine. I have 16" aluminum rims. And as a bonus, my rotochoks fit just fine. The spacing is great and the ride is superb. Like I said before, when my leaf springs broke, I wonder which hospital I would be in if I had E rated tires not 14 ply G rated Goodyears on. I was amazed that even after the frame sat on my new tires, they were in fairly good shape, with alot of sticky rubber but still usable. I did have to change one tire, but it didn't blow under that pressure which can't be totally attributed to my wonderful karma.
Lonestar, keep those barely used Goodyear 614's.

When we ordered our new unit I ordered the Goodyear 614's on it. Sure glad I did they seem to be a great tire. $700 option is really cheap when you consider thye cost of blown tires and damage.

All the best,

Not offered on the Cyclones - I sure tried though.
I guess toy haulers are not "luxury" enough.

The difference is you have 3 axles. That makes a big difference in tire weight, 3 versus 2 axles.

I have two axles.

Goodyear 614's versus whatever has nothing to do with # of axles, I read enough on many forums to know there is a serious issue with trailer tires.

Our friends "new last year" Cedar Creek had a blowout on the way to meet us in PA. $5000 worth of damage to the trailer.

He made out OK though in the end. All damage repaired and ??? replaced all 5 tires and wheels and upgraded him to the 614's at no charge. Even the spare was aluminum.

I am running 110# in the Freestars and was in the Goodyears. Here is a link to Goodyears weight/pressure charts. http://www.goodyear.com/rv/pdf/rv_inflation.pdf Will be going to Branson this weekend and will likely change tires back to the Goodyears when I return. Will be taking 2 extra spares on all road trips from now on.;)

Well, this is our 3rd year with the 08 3600RL, and I thought I would miss out on the tire issues until this weekend. One left rear has a buldge on it. I put on the spare. They are Goldway LT235/85R16, YTR05 tires on 7 spoke aluminum rims. Are these the china bombs you are talking about. Should I change all four:confused:. Also my unit seems to bounce and sway a lot, my wife says it's the way I drive but I think it's more than that. Thanks for your reply.

Does Heartland check the alignment and other things at these rallies, we are thinking of attending one. We live in Iowa.:D

Well, I guess I'm a member of the blown tire club. Picked up the new to us trailer on a Thursday and left for a short trip on Sunday. Didn't get 50 miles before I shredded a tire. I've blown tires before but never had one come apart like this. Biggest piece I saw flying was about six inches. Only left 3 inches of sidewall on the inner and outer bead.
I took a slightly different tack. My last 2 fifths have had Goodyear Wranglers on them. Made the deal that dealer bought 2 and I bought 2 so now have new rubber on the road. Same OEM stuff as from NuWa and Newmar so I'm happy.
