Thanks Emilys4G.
See I used to have a Jeep Liberty stroller with air tires and loved it. I was able to go all terrain all season whereas everyone else struggled with their strollers. That is why I was not sure.
Plus Roger said that they might start putting air tires on the 8-Seaters to make them easier to push.
I left the order with airless tires because I trust you guys and you have actually used them
