Question:
If my trailer tires are rated at 935lbs. Is that 935lbs total load weight? Or is it 1870lbs total trailer weight with load?

Expert Reply:
When a trailer wheel/tire like the bias ply Kenda # AM30120 shows a weight carrying capacity of 910-lbs, which is for Load Range C, that is for just the one wheel/tire. So, yes, you would double that to determine the total weight capacity of the axle/hub/wheel/tire system.
Do note that if one of the items in this system is rated lower than the others, then that lower rating becomes the overall capacity limit. For example, if a wheel has a rating of 1250-lbs but the tire mounted on that wheel is rated for 990-lbs, then the combined wheel/tire has that 990-lb rating; this is the case for part # AM30620.
Trailer tires should always be inflated to their rated maximum cold psi pressure as noted on the tire sidewall. It is never appropriate to under- or over-inflate a trailer tire for any reason.

Adam, I have 2 Carlisle 175/80R13 tires that say on each tire that the max load capacity is 1360 lbs. So based on the info in your post am I correct in understanding that to determine the max load capacity of the two tire I multiply the 1360 x 2? I realize that the trailer itself may have a different max load capacity to consider as well.
