I think you are too optimistic. 30 pounds = 13,6 kg.
When I changed my original 17-inch cast-aluminum wheels with summer tires (215/60R17)
to 16'' steel wheels with winter tyres (215/65R16), then I did some practical research
17'' aluminium was 21 kg (46,3 pounds)*
16'' steel was 22 kg (48,5 pounds).

* This is not 100% accurate, I weighted myself with the wheel and without it, using my bathroom scale

PS. This practical research was done, because I had a discussion with my workmates on subject "How much lighter are actually the Light alloy wheels?". About the same results gave Seat Leon Cupra

Some kind of swing out bumper mount would be the only way to go off of the back end and I've seem many license plates mounted to the spare when done like that.

OR if you did it from the trailer hitch you could always throw the spare in the trailer but that eliminates a bike rack but you could do that from the roof rack.

your right the tire itself weighs nearly 30 pounds... I was not sure how much the wheel weighed and decided to just use rough numbers to give you an idea but your right 45-50 pounds is closer to the truth and sounds much heavier.

I have heard that before too. Maybe the rack on top is not a bad idea

the 215/65R17 Goodyear Wrangler SR-A's weight in at 28lbs each and the 17" alloys weigh 12lbs, for a total of 40lbs.

of course, you still have the weight of the wheel weights, valve stem, center cap and of course, AIR to consider.......

.....or maybe a side mount spare tire, at the rear of the right quarter panel, where it wouldn't interfere with the gas door, license plate or tail lamp?

hmm 40 pounds - that may be a bit much to try and haul down out of the roof basket when you need it (without bouncing it off the side of the Compass on the way down)

Maybe a 2 rail slider that you can pull back and then lower with the tire on it?

OR get a 6 months membership to Golds Gym and work out!

just think.....in no time you'll be able to not only remove the 40lb spare from the roof basket, but change your MK's flat without the use of the JACK!!!!

I'd like to find a nice way to mount the tire to the rear, most likely not on the hatch itself, possibly using a rear hitch assembly like a bike rack. This could also provide some extra rear protection in case of accidents, as it wouldn't be directly on the hatch.

The issue is needing to raise the rear hatch. Maybe have the wheel swing sideways to the ground fairly easy so the hatch can swing open, and non Gold's members can raise and lower the wheel on the side of the road. Possibly using struts and leverage similar to what the hatch has

What'd be really sweet is to get a rear fascia mod and hard cover for the tire so it could resemble the concept.

So back to the idea of a fuel cell.......

Can you actually buy one that is the size and shape of a spare tire? Seems like a good idea..... I honestly think I'd mount my spare on the back or top if it meant a tire's worth of gas extra...

So you all talked about the tires weight, but how many gallons are in a tire?

gallon of gas = 231 cubic inches.

volume of a cylinder = pi times the radius squared times the height.

so a tire shaped hole about the size of a 30 inch tire 7 inches deep (guessing - cant be bothered to actually measure the patriots spare tire well at the moment) holds about 21 gallons
