Hi all, trying to figure out wheel load ratings and risk of overloading. I tow an 8K lb travel trailer with my 1500, my scaled truck weight is usually 7K lbs when towing, and I'm 400-500 lbs under the GAWR (4100 rear, 3900 front).
I'd like to change from my OEM wheels to the Black Rhino Alamo wheels, and it looks like the 1890ALA126140M12 part number is the right one (18x9, 12mm offset, 6x139.7, 5.5 backspace -- I am staying with 18 rims for more LT towing tire options). https://www.blackrhinowheels.com/off-road-wheels-rims-alamo.php
These wheels have a 2250 lb load rating, so 4500 each axle and 9000 total. Is overloading wheels something to worry about? I.e. if I throw some extra stuff in the bed of the truck for a short trip, am I going to crack a rim? Are there safety factors built in?
Also, the same rim with the 5.47 backspace listed just above (PN 1890ALA126140B12) has a rating of 2500 lbs instead of 2250 lbs. The same rim with a -18 offset (PN 1890ALA-86140M12) has a 3640 lb rating. Why the differences?
Thanks for any help!
