So you're saying it was an "upgrade" . . . kind of?
Any possibility that I could find Hub Caps that would fit?
Tires have manufacture dates on them?
Mark, it was a downwards upgrade...
These wheels and axles are used like Andy says, under mobile homes. They are also used under utility trailers, and even flatbed equipment trailers, such as would carry backhoes and buckets loaders. The "up" part of this is these wheel/axles will carry all kinds of weight, the "down" part is, it will shake the living crap out of an Airstream. I have seen similar axles under a few SOB trailers, all had loose/broken fittings and furnishings. It would be a good idea to get an axle/wheel assembly of the proper configuration and weight rating under you unit as soon as practicable.
You have a different axle problem from most of us.
If you ask him real nice, Andy from Inland (above post) would probably be happy to help you with the proper axle and wheel setup for your trailer.
As far as manufacture dates on tires, all passenger car size tires are required to contain , among other things, the company and place of manufacture, and the last three or four digits are a date code, as in week, week, year, year. So, a tire with this code of 5101 would have been manufactured in the 51st week of 2001.
And, even though you didn't ask, the tire wear rating, when multiplied by 2000, will give you an indication of about how long in miles a tire can be expected to last. A tire with a wear rating of 200 SHOULD last about 40,000 miles, with proper maintenance.
The tire shown in your photo is considered a commercial tire, and probably will not have either of these.
