Sold my camper, pulled some lift out of it and installing smaller wheels/tires. Stopped in the trailer store down the road for a quote and measure diameter to check fit. One thing I forgot to check is the center bore, and if its large enough to fit over the 3500lb axle hub. Anyone know? The wheel was 13x5 iirc with 5 on 4.5 bolt pattern and 3" backspacing. I can kick myself that I forgot the hub detail, and I think they closed for the day.
