New Rims

Old rims are 15x5 and are looking like they are from 2002. I painted them once but they just look kind of lame. Thinking about new rims and prefer steel. I use LRE @ PSI and found no adverts that actually mentioned PSI capability of a specific rim only load ratings. What weight rating would be appropriate for LRE inflated to 80 PSI? The cheapest have 1870 lb ratings.

George,

The "issue" or the "limitation" will be the number of lug holes in the wheel. If your wheels are "5 lug" then the maximum will be around 2100 pounds maximum capacity (65PSI)

If your current wheels are "6 lug" then the maximum rises to 2830 pounds/80PSI....

So, if you're axle hubs have 5 lugs, I don't think you're going to find a "standard wheel" to fit it that's rated at 80PSI/2830 pounds.... All the wheels I've seen with the increased load rating are "6 lug wheels"....

In the SENDEL brand, the "exact same aluminum wheel casting" has two ratings molded into the back side of the wheel. One is for 5H at 2150 and the other is 6H at 2830 pounds....

Here's a photo of the back of my wheels. I think you'll have problems finding 5 lug wheels that meet the 2830/80PSI rating.

Looks like you can get 2160# with this one.

Pretty sure I don't want fancy mag-type wheels as the budget can't stand the shock. Powder coat steel will likely be where I head but do thank you for the link. I do have the 5 lug on 4 1/2 I believe.

BTW: I have run 80 PSI in my steel wheels which were initially installed with LRD (65 PSI) and none have blown up in quite a few years but will try and 2160 lb rating to be as safe as possible.

To me, and I may be wrong, if a wheel casting is rated for 2150@65PSI and 2830@80PSI, dependent upon the number of lug holes, then it looks like (to me) that the wheel casting is the same and can carry the pressure, but based upon the support (number of lugs) it is limited in weight not pressure.....


Steel wheels, at least the ones I've seen, the center section is stamped with lug holes and that part is pressed into/welded onto the rim. I can't say for certain that the actual "pressure holding rim" is identical on steel wheels with 5 or 6 lug holes, so there may be some "technical differences in pressure capacity.... That's not the situation with an aluminum casting that is "drilled after production" to have either 5 or 6 lugs...

From what I've seen, steel wheels are typically rated with a higher weight capacity (and that means a higher pressure rating to carry that weight) than cast aluminum wheels.

You might find a local body shop that has the ability to strip and powdercoat your current wheels for significantly less than buying new ones that are rated lower then they are.

Sorry, I wasn't advertising wheel brand or design, just the fact that 15X5 wheels, depending on manufacturer and design can, support 2160# of load capacity.

Understand the valuable input. I might just go up to the camper and hit those wheels with some Krylon. I do have a trusted powdercoater who has a system that can blow off the old finish down to bare metal but probably would be easier to buy wheels and drag the camper to the tire shop and let them remount the current tires which are fairly new and in great shape.
