Thread: Carrying a second spare tire.

Th only time I have ever seen a spare mounted to a front of a vehicle was the old VW camper vans of days gone by, they had a spare mounted to the front bull bar. We tend to hang things on the back with a custom made duel wheel carrier on the rear bumper. similar to this set up.
Twin Wheel Carrier.

I agree with Roverlord. Apart from the issues of airflow, I would be concerned about having the weight of the wheel that far in front of the front suspension - the front suspension is not really intended to deal with variable loads - it has the engine, and a small proportion of the variable load, with the rear suspension dealing with a much wider variation.

And then there is the question of its effect on forward vision, especially on sharp crests.

I carry extra spare wheels when required (as on a remote area trip) , secured on the roof rack of the Disco.

Yes, I know that they're heavy but I use alloy rims and I would be reluctant to hinder cooling airflow.

I always tow a boat when I go away and the second spare goes in the Boat

I have a second spare for long remote trips. The rest of the time it sits at home.
I had a rear carrier for my D2. Before that the extra spare went on the roof.
I would not mount it on the front for all of the above reasons. Lack of airflow at speed will be costly.

Mounting your spare tyre on the front of the vehicle would have numerous implications for you, as has been mentioned previously.
The lack of air flow would only be an issue at low speeds when the engine is working hard.
More concerning would be the additional weight on the front suspension and the leverage effect of mounting a spare tyre high up on a brush guard.
One solution is to carry only the spare carcass of the tyre not the tyre and rim as this would reduce the weight significantly, you would then have to mount the tyre yourself, which can be done with some tools and some practice. The spare carcass, I would still throw up top on the roof rack as this should not add significantly to the overall weight.
You will still have one spare tyre and rim for quick changes and should you use this up you can then repair the damaged tyre or replace as necessary at your leisure
I hope that this helps

I see it is getting popular to strap spare carcass to the complete spare.....

Quality tyres and adjusting tyre pressures to suit condition greatly reduces tyre failures.

There may also be legal issues.
Mounting a spare up there could interfere with the crash crumpling and operation of seatbelts/airbags.
It might void your insurance if you made a claim.
It could affect pedestrian safety if you hit a pedestrian. I assume there are laws about that in the US.
Over here, we usually put second spares on the roof racks..
