Thanks to all thus far.....appreciate the input. To answer one of you re: what trailer: We're looking at the Keystone Sprinter Copper Canyon 269FWRLS and I saw it came with 15" tires (ST's I'm sure) but could not find an axle rating and couldn't get a response from Keystone, at least yet. The factory specs show 8,739 dry, capacity of 3,094 and thus a GVRW of 11,833. I'm thinking the 15" tires should be replaced with 16's but wondered about axle ratings for this one.

Here are your trailer's specs.

How many lug nuts per wheel? Tell us more about the trailer. 5K is usually 5200 pound axles, and will have 6 lug nuts. 6K axles could have 6 or 8 lug nuts. Chris

Not always true. Mine has 5200# axles according to label, with 8 lugs.

If the axle is from Dexter, send them an E-mail with the serial number of the axle and they will send you a copy of the build sheet showing everything about it. Been there done that.

Our CF335SS has axles rated at 5200 lbs each. 16 inch aluminum wheels (16X6J) with 6 bolts. Weight leaving the factory was 10,014 lbs "dry".
Last CAT scale Trailer Axle weight was - 9220 lbs

As soon I took delivery and got it home I checked all of the suspension bolts (many were not tightened to the correct torque spec) and found a data sheet taped to the axles - had the serial number, date/time of manufacture, weight rating and a parts listing.

Your trailer manufacturer does not have to use the axle rating from the axle manufacturer.

They are allowed to set the trailer’s GAWR below the actual axle rating to achieve the GVWR they desire for the unit.............Look at your trailer's certification label for its certified GAWR.

Correct. My axles are actually 5k, but down-rated to 4200k by the RV mfgr. That caused me some difficulty when I needed to replace by brake backing plate assemblies, but a call to e-trailer.com resolved the issue.

There will be a metal tag on the axle tube itself that will list the rating serial number etc.

This is how I would do it.

They are allowed to set the trailer’s GAWR below the actual axle rating to achieve the GVWR they desire for the unit.

In other words, the vehicle manufacturer may set the trailer’s GAWR to 5080# from 5200# axles. It is often seen when that manufacturer wants to use tires rated at 2540# for the unit.

Of course there are many other examples to use.

Look at your trailer's certification label for its certified GAWR.
