Roof Mount vs Back mount.

I've heard differing opinions on both rear Tire mount and Roof, now I'm confused as to what I should get.

Both seem to pose issues weight wise I've heard.. but is that really true?

Is one REALLY more efficient or better then the other?


Also,
If you have a mount, post up a pic, I'd like to see how you have yours set up.

Thanks guys.

it might help if you state what it is your trying to mount, i assume its a spare tire.. just busting your balls

id say the rear tire carrier is more efficiant because of the wind drag. throwing it on the roof would cause loss of MPG and with gas prices every mile counts.

Haha dont worry about mileage when you drive a jeep. Its basically a personal preference.

I had a spare tire mount that went into the hitch, it swung down, and was a pain in the a**, i have a trocko rack now with the tire mounted on the roof and its much better, dont even know its there. Much better. Take a look

Think it boils down to preference, a friend of mine doesn't want the rear mount since his wife DD's the rig periodically. A little harder for her to move the tire out of the way and such so he is choosing the roof.

I love the look of rear tire carriers and roof mounted tires. But the rear mounted tire always seem more "efficient" to me because when you start thinking about a lifted jeep running 33" + tires its going to be hard as hell getting that tire up and down from the roof if you need it. Where as on the rear of the vehicle its easily accessible. With this said i still went with a roof mounted spare time for a couple of reason. First reason is most rear tire carriers are extremely expensive. Second, when running larger tires you can pretty much count your rear viability out of the question. Lastly and what was the deal killer for me, is that every time i want to get into my hatch i have to open and swing that damn tire carrier. I know it seems minimal but i get into my hatch a lot and it would be a huge inconsistence. So i went with a roof mounted!

Just my .02 cents.

rear mounted carrier would be superior IMO. less drag, easier accessability, less top heavy, protects rear of jeep, strengthens rear unibody. now if none of those matter and you want to do it on the cheap, then the roof would be a better option. i have my 33" spare sitting in my cargo area at the moment.

there are advantages to both, personally i love the look for both, but for the roof the wind drag is a HUGE issue to me with MPG loss. and the loss of visability on the rear is another big issue, i personally dont keep my spare with me. im rarely ever far from home as to where i couldnt have someone bring it to me. if i am going far or on a wheeling trip i may throw it in the cargo area, but even that doesnt happen much. eventually im going to be running bigger rear shocks through my floors and there will be a bar ataching both shock hoops together, and it will be mounted to that.

bu what size tires are you running? theres w thread somewhere about modding the rear seat latches up a little to clear a 32" tire, im sure a 33 aired down it would fit. im on 35's and tried to stuff that in the stock lotaction multiple ways but that was a huge FAIL

x2 on not having the tire on the roof. I did that for a day and could feel it slowing me down on the highway. Anything bigger than a stock sized tire would probably act like a giant sail.

Mehhhh ....

Just be indecisive like me ..... and cover all the bases ....





Either location has faults ... Its just a matter of working out which way has the least faults for your requirements.

As for the additional fuel use with a roof mount .... How many hundreds of miles are you going to travel non stop at highway speeds, to notice the difference ?? .... My little stock wheel only costs me about 1mpg on a trip - but maybe the larger and knobby tyres have more effect ??
