Quick question - I'm delivering a 2000 Laredo to Cabo for a friend of mine. We are driving down and don't anticipate much off road use at all. It's got larger tires and a lift on it and the spare does not fit in the tire well. We have a few items to take down so space is at a premium inside. Is there anything wrong with putting the tire on the roof and besides my though of ratchet straps what would be the best way to tie it down?

Thanks!
