I recently looked at a 320 Solitude. I recall that it had 6 lug, 6,000 lb axles, but I don't recall the tire size and rating. I also remember that the brand of the tire was not a national brand that I was familiar with. So thinking ahead to a tires upgrade, I am wonder where I would be starting from.
So if someone could tell me what the wheels are rated for and what size the standard tires are it would be very helpful.

Thanks in advance for any help.
