Wheels on Trailmanors

Hello, this is my first post. My hubby and I will most likely be purchasing a Trailmanor in the near future. We've decided on Model #S720sl. We were also looking at the Hi-Lo brand but like the Trailmanor because of its compact towing size. The Hi-Lo has 2 tires on each side of its trailers, and we notice the Trailmanor only has one on each side. Hubby wants to know if anyone has experienced a blow out of any kind, or if anyone is aware of the reason for Trailmanor's 2 tires versus Hi-Lo's 4. We have yet to go to the dealer in our area, so I thought some feedback from experienced owners would be helpful beforehand.

Thanks for anyone's assistance.
