    As you can see in my signature I have a 16' X 8' double axle trailer. Supposedly 3500# axles. How do you tell what the actual capacitance of the axles are and what size tires should I be using? A guy had mentioned that my tires were too small and weren't intended for the heavy loads. Any help would be appreciated....Thanks

    5 lug are generally 3500# axles. P rated tires are fine for lighter trailers like that. If you want a little better durabliity you can look into tires that are specifically rated for trailers. I run P 215/75R/15 tires on mine. I went with the less sidewall to lower the trailer a bit. 235's make the trailer just sit a bit too high and my mowers have more chance to drag on the gate hinge.

    on the side of the tire it should tell the weight capacity of the tire at a certain air pressure. Im not sure about the axle there may be a tag on the axle that gives that info. I have a tandem trailer rated for 7000 lbs. I usually haul about 2500 lbs plus the weight of the trailer. I will probably use an automotive tire when I replace them just because of the price and longer life of a radial vs a bias tire. I carry a Z (1000 lb) a walkbehind(600 lb) 21'' mower, wb edger, 3-4 trimmers, bp blower, hand blower, hedge trimmers, chainsaw
