Similarly sized fiver here- I had individual wheel weights done and found that I was over capacity on 1 tire and at capacity (3,400 vs. 3,420) on 2 others. I went nutty and upgraded my rims/wheels (17.5") + tires (load range H) for a much higher load carrying capacity. Turns out, going from 16" to 17.5" rims, you use a lower profile tire and my outer diameter actually shrunk by about 1/2". Which is good- my spacing is such that my tires were already really close.

ependydad, what 5ver do you have? I would have expected the bigger wheels and tires to make the gap worse. If you gained spacing, can you us the x chalks on there? do you even use chalks?

It's a Sabre 36QBOK. Very similar in layout to a Sandpiper 365SAQ (dual/opposing slide bunkhouse).

The reason that I gained space is because the sidewall height of the tire is much less. So, while it's a bigger wheel- it's still smaller on the outside. It took me a few readings from another guy before I finally understood.

I went from a 235/80/R16, lead range E. To a 215/75/R17.5, load range H.

And yeah, I use Rotochock brand chocks. Similar in concept, just different implementation.

It didn't appear that there was any kind of road damage so I took it in to the RV dealer to ask him about it. Since we were just over our one year warranty he said " just buy another tire and put it on, the other ones will be just fine". I asked him if upgrading to an E rated tire would be better. " That's just overkill why would you want to do that?" He also mentioned that the C Rated tire that are on our 8289 WS are close to the max limit. MMMmmm Well, I decided to go with the E rated Carlisle radial trail tire from Discount tire and What a difference it made. We made a 1300 mile trip to ND and back and there is no more sway. The stiffer side walls made all the difference on how the truck and RV go down the road. I don't have to fight the wheel any more. I know too that Discount tire is all over the country so I know where to find a replacement should on be needed.
Happy Camper

What is the tire PSI that you are running? If you didn't change the rims they are only listed for 60 lbs PSI stamped on the inside. Are E rated tires psi 80 lbs....

I'll have to look them up. Have the x chocks on my list of need to buy items.

gljurczk, I'm running 80 psi in my tires which is what their rated for. My rims are rated for 80 psi so I'm good to go.

We got our new 2016 Sandpiper 371 in May. I have 2 tires that are failing already. It seems to me that they are under rated for the weight of the camper. 3520 each...

In the process of going through warranty with the dealer and upgrading them all to 14 ply's. Looking at the Sailun S637.

Anyone else experiencing problems with their tires?

I have about 3000 miles on my Carlisle Radial Trail tires and what a difference the E rated tires made. My 8289ws pulls like a dream now. I'm happy I made the switch and I don't have to worry about WHEN I would get another blowout with the old (ha) tires.

That's great they have put a better rim on, maybe they are not using Lionhead anymore for a supplier. I know mine are stamped 60 PSI on the inside.
