weight rating - tires

[glamourpets]

What is the meaning of a weight rating for a tire. If a tire is rated for 1000lbs, does that mean

1000 lbs per axle?
1000 per tire (or 2000 lbs on an axle with one tire each side)?
1000 lbs total for the entire trailer?

The same rating could mean very different things.

Derek the load rating is per tire.

Since you don't specify trailers I presume the question is about tires generally, so I'd add to Carol's answer that in dual- wheel applications tires' load carrying limits are downrated, see examples on chart here

Note: "Dual wheel" means double pairs on a single axle.

Correct - but it's "dual wheel", not "dual axle". A pickup truck with dual rear wheels is usually identified as "DRW" in manufacturers spec sheets, and is informally called a "dually".

When specifications include a load index (not a load range), tires intended for dual applications have both the load index for single use and the load index for dual use shown, separated by a slash. For example, 112/110 would mean 112 in single use, and 110 in dual use.

Of course, I've never seen a moulded fiberglass travel trailer with duals.

Thanks- fixed! Started out as "dually"...

As I think I indicated, the O.P. didn't specify that the question was limited to trailers, so I thought the downrating of duals was worth mentioning.

1000 pounds per tire, as noted and up to 2000 per axle. I say that because weight on a trailer axle is rarely evenly distributed side to side and you can't use all of the axle's 2000 pounds if it means one side is over 1000.
