2005 Keystone Everest 344J Aluminum Wheels/Tires

[gascott]

Is anyone still using the 16x6J, 12 hole, 8x6.5" modular aluminum wheels that came as an option on the 2005 Keystone Everest 5th wheel trailers? Can they support Load Range G (110 psi) tires? I called Keystone and they didn't know who manufactured these wheels, so I can't call the manufacturer to find out if these wheels can support 110 psi tires. The markings on the back of the my wheels are: TTW INC., Made in China, 16x6J, MAX LOAD 3042 LBS C, TR4 ZNL, DOT-T. Original tire size is 235/85R16E (80 psi). My 344J model GVWR is 14020 lbs.
