Referring to 16" 6 x 5.5 wheel ratings.
16" 6 lug range into 3800 lbs. But vary in between. Mine are16x7 6 5.5. Rated at 3200 lbs. Goodyear tires, ST235/80r 16 123N, rated at 3420 @ 80 lbs. I went from 2800 lbs, to 3400 lbs per wheel and an 87 MPH rated speed @ 80lbs, for a bit of safety 'cushion.'
Heavier 16" 8 5.5 lug rims range to 4800 lbs each.
Nothing is gained by installing wheels that have much higher capacity than the axles. That said, the rim and valve stems must be suitable for the higher tire pressures found on G rated tires.
I would guess that 110 lbs of tire pressure would be rock hard and would hammer the suspension if not designed for such tires? Reducing pressure in order to improve the ride quality defeats the load and speed capability.
The sweet spot is understanding the tradeoffs.
During hot weather, tires are seriously degraded by reducing max inflation. Less than max inflation also reduces sidewall curb damage resistance.
I've entertained placing a camera inside the camper to get a feel for the ride....not sure I want to know...have a Furion rear cam and it seems smooth enough from the rear. Dunno.
New tires will get a workout soon. Have golf cart and other toys loaded up.
Also programmed the TST 507 to the trailer. Very nice TPMS monitor...so far.
Will report any issues.
