In my search for upgrading Tires and Wheels for my F350 SRW several large tire / wheel dealers suggested the Method 305 NV Heavy Duty Wheels. I just installed these wheels and they’re listed as having the highest load rating for 18” Wheels that I can find. On the backside of the wheel it’s stamped (6 Lug 3500 lb rating) and (8 Lug 4500 lb rating). So clearly this manufacturer is labeling the weight rating for Lug Nut Application. How many wheel manufacturers stamp the Lug nut weight capacity by Lug application?
This thread has opinions on after market versus OEM wheels and my Super Duty F350 SRW is not a grocery getter it was purchased to haul a 12000 lb 5th Wheel or my new 89RBS Adventurer Camper. The F350 OEM Wheels at 3650 # rating would cover my 7000# Door Sticker for the rear axle weight, but the Campers loaded Wet weight is a little over and this prompted upgrading to the 4080# 295/70R/18 Cooper Tires and the wider 18x9 Method Wheel at 4500# Rating. Attention to monitoring Tire Pressures often and checking Wheel Torque especially the rear axle has been a Standard Operating Procedure for many years of RVing.
