I've had very bad luck with tires on my dually due to separation issues. I'm only getting 15k to 20k before this happens and 3.5 to 4 years. I only have the camper on the truck about 3500 miles a year, and the truck is always in the garage if the camper is off which is most of the time. The camper is a 2000 alpenlite 1150 limited, and weight is around 4800 lbs ready to travel. Sticker on the camper states 3600 lbs. I've owned this camper since 2004 and had the rig on the scales back then. I remembered I was under the capacity then however I'm unable to locate the form now. I plan to have it on the scales on my next trip, but thats not till august. The tires have all been E rated and are run at the 80 psi cold while carrying the camper monitored with a TSP system. The first set were BFG commercial. The second goodyear wrangler. I have a lesser name brand on the front WEstlake that are 5 years old and appear to be wearing well, they were the only one available at the time I had a failure while traveling. Wondering if others have had issue and what brand seems to be working for others.......Thanks

Your experience is not normal. And you don’t say which axle has tire separations or both. Nor do you say what size of tire/rim.But if you’re on 215-85-16s or similar pizza cutters, you are far closer to being at max tire capacity on the front axle than you are on the rear axle, even with the camper loaded. And if it’s a diesel and/or you have any additional weight on the front axle you might even be overloaded on the front tires If your original tires on the truck new were the commercial TAs I’d blame the cheap junk sub par tires that mfgs put on many/most vehicles. Second set, you are not specific what model of Goodyear tire, as there are many wrangler models, but were they LR E and a quality model? IE no not cheap OE/Wallyworld looking models. Personally I’d not run off brand tires like Westlake either. No it’s not normal or usual to have tires separate. Period. It’s either weight, cheap tires or the worlds worst luck. Since it appears the tires are treated pretty well.

We've had BFG T/A Radials on my PU for years - 285-E - and never had a problem with weight. We keep them at 75-80 psi rear, 65-70 front. Been using them on our construction trucks (three) for just as long until we retired. Been camping-RV'ing with Truck Camper since 2002 - Lance 845 on its back. Truck is HD2500 SB - 6.1L w/410 RE ... Hope that helps. Just one opinion. M44

I like Toyo tires. They aren't the cheapest, but last well.

I had separation issues on my Dually. PO had put aftermarket wheels on an it put the sidewalls of the rear tires too close to each other and they would overheat. There really should be well over an inch of space between the closest part of the two tires under load. I ended up putting in a spacer. I haven't had a blow out in 5 years since I did it vs one inner dually a year on the right side ( high crown loads).

Thanks for the replies. Since they prorated three of the four Goodyear tires on the rear. and the other has 15k miles I plan to run them for awhile. I'm aware Westlake tires aren't supposed to be a top tier tire,but so far they have out perform supposedly better brand tires. The rims and size are stock and I have around an inch between the duals when loaded. Temperature and psi is monitored with a TST system. The BFG separated on the front first,then two later on the rear. The wranglers were only on the rear, since the front were nearly new..... Buzzcut1 I thought about a spacer between the rears. Could your provide the type your using?? Thanks to all and anymore thoughts appreciated.

You can use dodge rims. Look at the offsets. There’s dually wheels that fit 235/245 width tires just fine If the old GM rims are too narrow. Or not enough offset.

Put Michelin or Bridgestone/Firestone tires on your truck. My 2015 GMC 3500 dually has a AF 990 that weighs 4500+ lbs and my original Michelins will go 50k miles easily.

My 2002 dually came stock with 235/85/16 which care 3042 lb versus
the 215/85/16 which is a little over 2600 lb. I
am always told when looking for tires I have the wrong
size on my truck but my door sticker says different.
235'may give you more capacity and will still fit. Just a thought.

No pics needed. As identified earlier, a big part of the issue is, you’re running those little tires to death IMO. Combined with either some bad luck, bad roads or cheap tires.
You have a repeatable problem it seems so I’d expect to have to change something to achieve different results.

The truck is a 2003 3500 ext cab two wheel drive diesel dually. Running stock size tires 215/85R16. I only had one front tire seperate,that was a BFG.rest have been on the rear. I thought about going to a large tire,but was afraid it would make the rear space even closer. Since three of the four rear are new replacement Goodyear and the other has 15k I'm just staying with them for now. As far as posting photos may be easy for some. Just like rebuild a Pontiac engine is easy for me...

^Yeah those little tires get overloaded pretty quick.
Stepping up in tire size is generally always preferable for heavy loads. As long as they fit and you can pull em.

10-4 Mr. Gritdog,

Maybe the OP has had some bad luck as I did for several years and is frustrating.

Fortunately my tire failures were detected by vibration from the bulge in the tires or by inspection at a stop and pulled off before they blew. Always on a rear tire either side. Had a series of this problem ( maybe 4 times over 5 years) only during the summer hot months with camper on) with Goodyear Wrangler and Remington tires not bought at the same time. I believe Remington was also made by Goodyear at the time. Running Hankook the last 6 years with no problems and now on my second set using the new tire pressure gauge over that time frame.

Don't trust the cheep gauges and cross check between gauges. Insist on steel valve stems. Check the TP first thing in the morning before the sun hits them. Inspect at stops. Avoid potholes! Good luck with that.

80 lbs per tire gives about 280 lb extra carrying capacity on the rear axel vs 75 lbs per Goodyear chart on my stock 245/75/16 E rated tires. 6084 vs 5800. These tires were widely used on class C motorhomes as well in a dully configuration.

Next truck will be a dually and of course a heavier camper!

Thanks, I'm keeping a list of recommendation, and will add Sailum if they offer a road tire.
