Latest Update - It appears from the australian website, the rims are indeed tubeless. So, tomorrow we are going to dismount the tires and see what's inside. As cooperman said, it should have a safety ridge.
from the longstone tyre website: "Only in tubeless tyres with a series or aspect ratio equal or higher than 70, i.e. 185/70 x 14 would be ok, 185/65x14 would not". That would rule out the 195/60/15 installed and the standard on the 91 plus 4.
Enough to drive you crazy! We'll see if there is a rim band or any type of sealant on the .. I'm guessing probably not since a tube was used. I'll be on the lookout for the yellow sticker on the inside!!!
Thank You to all for sound advice.
