Newbie with Wildwood 29bhss

Westend- Not sure if I can even get in there to look at the tires, but I will have plenty of time after I pull it out in April. I won't have to pull it at highway speeds until late May or early June. As far as the wheel bearings go the previous owner told me he had the brakes inspected and bearings repacked every year, so I will continue that practice. I inspected the roof just prior to placing it in storage last October, and it was in good shape. Furnace worked well 2 weeks prior to storing it. As far as the tires go, I do believe that they are more than 4 years old ( I sent a text to the previous owner to ask if he knows and I am waiting to see if he replies), so I will plan on replacing them. Do you have any idea on what I can expect to pay (just looking for a rough guess). Also does anyone have any recommendations for a brand/model. (I am willing to spend a little more for a higher quality tire). By the way the dry weight of the camper is 6250 lbs, so I figure about 7500lbs loaded with no liquids.

Thanks again,

Sean
