2008 fuzion rims

[maxx1963]

So I have a 2008 fuzion 362. I just read on another forum about how bad the 15" wheels and tires are. Has anyone had a problem with this?

[KenBob]

Are the concerns with 15" tires/wheels in general or is there a specific RV, tire, wheel that the concern is about?

RV tires (specifically trailer) have been a hot topic on every RV forum. Good and bad. Wheels not so much.

We have 15" tires/wheels on our Cruiser. No complaints.

I think the main concern was not bieng able to get "E" rated tires for 15" wheels, but I read some things on here last night that said you could get them. Need to look into it.

I also read that my axle's are only 5200# rating. That's 15,600#. Why is my gvwr 16,000#?

I just dumped my 15" Towmax D's for Maxxis 15" E's. It was a matter of time before I blew a tire. The Towmax D's were just barely adequate for the 12k fiver.
I checked my rims, and they are rated for 2830 each which is equal to the rating on the Maxxi's @ 80psi, which is what I'm running them at. I also had them balanced. The E's are the right tire for my trailer in my opinion. They ride so much better too. I paid $800 out the door mounted, balanced and installed. The date code on them was 3/12. I inspected the construction, weight and sidewall thickness between the two and there is no comparison. I can't believe Keystone outfits trailers of this weight with tires that "just" get by.

Several posters have reported wheel leaking problems when they overloaded them. Rims are rated, just like tires. Rating usually stamped on rear, or in valley UNDER the tire.

For example inflating a LR-D tire to the sidewall rating on a LR-C rim is a THIRTY PERCENT OVERLOAD. Not anything I would do.

Also if changing tire size, watch required rim width. For example 225/75/R15's need a 6" width, while most 205/75R15 tires (and their rims) use a 5.5" wide rim.

Safety factor

It's not safety factor when the GVW is heavier than the axle's can carry. Nearly every fifth wheel made today is rated with the pin carrying part of the GVW. On mine, the GVW is 8100 lbs. There are two axles under the trailer, each rated at 3500 lbs. That's 7000 lbs on the axles. Ironically, (or not) Keystone rates the pin weight at 1100 lbs. Add the axle load capability and the pin weight and you get 8100 lbs. On my trailer, it's just exactly what the GVW is... However, on toy haulers with so much of the cargo weight being carried behind the axles, there is a greater load on the axles and thus, when GVW is figured, it looks like Keystone uses less of the pin weight in the calculation.

If you look at nearly all the specs on fifth wheels that Keystone manufacturers, add the axle rating and the pin weight and you'll see that the GVW is "right there"

So to answer the OP's question, the GVW is factored on axle rating PLUS a part (or all) of the pin weight which is not considered to be carried by the axles, but by the truck. This increases the GVW while allowing the manufacturer to use lighter axles and still maintain a higher GVW.... Cheating??? Make your own decisions about that.

Not that I am happy about that, but it makes sense.
