Please respond with any helpful suggestions.
IMHO you are nuts to continue with 16 inch tires. Get a set of 17.5 inch tires/wheels. Their nominal load rating is around 4500 each. This should nearly end your problems for ever.

Very good advice, that 5er is heavy and you can't have to much tire.

Changing tire size is one thing, but changing tire size and wheel size is a bit much for most people considering it is not necessary. There are literally thousands of 5vers on just oversize tires or heavier lr tires that are not having problems. Tire pressure monitoring is probably the best blowout prevention you can get other than having the proper tire size for the load.

How hard is it to bolt on new tire/ wheel? TPMS will not prevent a tire failire. All it can do is warn s driver there is some loss of air pressure. For any trailer over about 14,500 GVWR. 17.5 inch tires are your best insurance. With load ratings in the range of 4500 ounds each chances of failure because it is at capactiy are non existant.

I think he is meaning more on the price side of things. I am looking at 1" larger rims and better tires for our 3000 mile round trip to Canada and it's a good week's paycheck for the combo. Also, TPMS will allow you to ensure that your tires at optimal pressure. Incorrect pressure will lead to failure, so I can see that as prevention.

Definitely talking about the cost factor. Buying tires is a pretty good hit for most of us and then add the cost of wheels is a big hit. A tire pressure monitor should be used regardless of what size tires are used. Even tractor trailers use them and they have real heavy duty tires and a lot larger wheels.
Just saying.

I guess it all boils down to how much is it worth to you sitting along side the road for a few hours waiting for a tow truck to haul your damaged trailer. And how much is a ruined vacation worth? A grand for marginal tires or 2500 for peace of mind. Your choice.

Thank you, and all other respondents.


I am not worried about the price difference in upgrading my tires, I'm of the opinion that quality is everything. One good set that will last will surely save me money in the long run.

The plaque on the 5er states the tire size and recommended pressure. The manufacturer is certainly pushing these tires to the limit as the pressure on the plaque is the maximum for the tire at 110 psi cold. The tires are rated for 3451 at that pressure.

I would love to go to a larger and higher rated tire but after measuring them just now I don't think Forest River had that in mind when they designed the rig. I measured exactly 2 inches between front edge of the rear tire and rear edge of the front one. I'm obviously not an expert on tire size fuzzy math. Can I get the 17's and stay within the existing overall tire dimensions? I don't think I can get heavier than the current load range of "G" while staying in the current size of LT 235/85/16.

I don't currently run an active tire pressure monitoring system, but with my problems I have been very vigilant in checking them before getting on the road each day and when I stop for fuel or any other reason for that matter.

Thank you again

Any and all ideas or intel on the matter is greatly appreciated.

With a thought process like that, why bother leaving the house at all. I mean, an asteroid could crash into you while going down the highway

In the real world, things are going to happen. It's Murphy's Law at its finest. You could "invest" in that $2500 set of tires and wheels, and have a nail, sharp rock, or such leave you in that same situation while the guy that didn't, and many the others that haven't, go on without issue.

While I agree that it is best to mitigate as many problems as possible, some people just don't have the means to do so. You wouldn't tell someone on minimum wage with a rusty 1992 Ford Tempo without airbags or ABS "You're nuts to drive that unreliable car without airbags and ABS! You should buy a new car" For many, you do your best with what you have and make it work. A used TPMS for, give or take, $200 will help a person without that couple grand get along with their setup.

In the end, leave the fear mongering to the insurance companies and the government. That's what they sell. For the rest of us...

PS: No offense to the insurance agents out there.

OK, folks,

Thank you for everyone who took the time to respond. As you can tell, there is always robust debate when tires are the topic.

It is clear that changing tires and/or rims is not for the faint of heart and requires a lot more study than reading opinions on an open forum.

Besides the extra cost involved, there can be substantial risk if the wrong tire/rim combination is placed on your camper.

As always on an open forum; "Caveat Lector" or Let the Reader Beware.
