Places to carry a second spare? For some expeditions, I like to carry a second spare tire. For example, when I did the Dalton Highway up to the Deadhorse on the Arctic Ocean, I carried an extra because word is that there's lots of metal junk along the 250 mile unpaved stretch from Coldfoot Camp to Deadhorse. I did get a bolt through one of the tires, but it held air until I got back to Fairbanks and I changed it there. This photo was taken atop Atigun Pass on the Dalton Highway, it's July and it's snowing. I've got an extra spare on the roof rack and also jerry cans on either side of the Jeep because there's only one fuel stop in the 500 miles from Fairbanks to Deadhorse:
On some British military "Wolf" model Defenders, the spare is mounted on the side of the hardtop. Not sure if this makes sense for a Grenadier.
A more common place to mount a spare on a Land Rover is on the bonnet:
The Camel Trophy Defenders, part of the most difficult offroad challenge in the world, were fitted with 7.50x16 Michelin ZXL tires. There were two spares, one on the rear door and one on the bonnet. These are significantly narrower than the tires on the Grenadier:
Not sure that's a good idea either - the Grenadier hood is higher than the Defender hood and the tires are wider than many Defender tires, so it migh obstruct vision too much. And I wonder if the Grenadier hood is reinforced enough to hold a heavy spare. Land Rover hoods for carrying spares have a recess the tire sits in, and their reinforced underneath.
Another Land Rover option; I haven't seen one of these for the Grenadier yet...
Another dual spare carrier, this time on a Discovery that probably is traveling far from the nearest place to get a tire fixed.
