Question:

REF: Kenda 5.70-8 Bias Trailer Tire with 8 White Wheel - 4 on 4 - Load Range D Part Number: AM30153 I have interest in the above item. Since the tire load rating exceeds the rim load rating, is there any point to purchasing this tire/rim vs a Load Range C product like the AM30130? I ask because I would prefer the galvanized rim, but there wasnt a Load Range D tire option.

Hey Keith,

For a tire and wheel combo the capacity you use is whatever is lowest. So on that Load Range D tire # AM30153 even though the tire is rated for more, the wheel is the same as the galvanized option # AM30130. Theoretically they have the same capacity even though one has a better rated tire. I did look and that is the highest load range galvanized rim we have so I recommend going with that option.

What kind of trailer are you wanting to put these on?

Hey Keith, did you decide to go with the galvanized rim option for your trailer? I'm interested to know if it met your needs, as it might help others in a similar situation.

Hi Nick, Thanks for the reply and the follow-up. I haven't made a purchase yet but getting close. The tires+wheels are for a small 5' x 7' utility trailer. G.V.W.R. = 1820lbs; Dry Weight = 340 lbs. So two Load Range C tires at 910lbs each meet the G.V.W.R. I recognize that the 910 lb-rims would be the limiting factor of Load Range D tires (1075 lbs each tire), but then what does the "better rated tire" buy me e.g. longer life, resistance to aging, resistance to road hazards or flats, better handling? I assume there must be some benefit otherwise it wouldn't make sense to offer a tire with a higher Load Range Rating than the wheel. One other question out of technical curiosity; it seems coincidental that a wheel rating happens to exactly match a tire rating, so from a from a mechanical/structural point of view, what's the characteristic of the wheel that limits it to 910 lbs? I also found a 8" x 3-3/4" 4-on-4 wheel online (no tire) that coincidentally was rated for 1075 lbs, exactly matching a Load Range D tire. Your thoughts?

@KeithA The better rated tire, although maxed at the rims capacity is going to give you longer life, its going to wear evenly and it wont ware as fast as a lesser rated tire. Most higher rated tires offer better handling as well, it just can't hold as much of a load as its tested for due to the rim. In terms of the technical aspect of it, the rating on the tires are just what they are tested for over and over to see what it can withstand. Material and bolt pattern play a part as well. If you found a rim that fits and is rated for a higher capacity I would go with that option over limiting the better tire.
