I have my spare in my basket on my grand cherokee. I just bought a couple really good quality bungees (ones that won't break in winter) and strapped it down. It doesn't move, and it costs next to nothing.
i hate having my 285 spare up top, but no place else to put it until i get my bumper.
all i can say is that it is heavy enough to not need the tire hold down. yes it weighs around 85 pounds (never really weighed mine)... but if you plan to keep it up there forever then buy the yak hold down. if you plan on taking it down often, or plan on getting the spare tire carrier... then just use a ratchet tie down.
frickin tire is HEAVY! and a PITA to take down and put back up... so for now mine stays there until i need it... or one of my friends is around so they can take it down haha
well this kind of ties into that, what is the weight difference between the steel "X" wheel and a regular "S" wheel??? Because, if it's only like a 5 pound difference, I can deal with taking that down. If it's like 15-20 lbs more, no thank you
Last I heard, Yakima was discontinuing the spare tire carrier for their roof rack. When I bought mine, I checked several places and finally found one in stock at Courtesy Parts for $75, I think. If you can find one, it is worth it, especially if you don't have a rear bumper with tire carrier.
It is a PITA to get the tire up and down off the roof, but not impossible. A 5 or 6 foot stepladder definitely makes things easier. Although, most people probably don't go offroading with a ladder! LOL
