Look guys I am no authority on anything but I’m going to tell you something about tires- I learned this from a very intelligent RV owner.
Now this may not be the case with this particular vehicle.
Every spring we see some guy who purchased a boat that’s been sitting in somebody’s yard on the side of the road and he’s got two flat tires.
What happens is when the vehicle is sitting in the grass or on damp earth the rubber absorbs water and the steel belts rust. The tires fail. This is why they sell pads to elevate tires off the ground.
Since I was a kid, my dad has always laid out some concrete paver blocks next to the shed whenever we had a farm truck to park there, to keep the tires off the ground.
