Is there any advantage or disadvantage to keeping the spare under the hood. OR is it better to keep in the back or racked on the roof?

 

Does is help structre or does it do harm but creating more heat?

the reason for the tire under the hood is that incase of a car accident it pushes the motor down instead of letting it go into the passenger compartment

I think the reason for putting the tire under the hood, was cause subaru can. I dont think it makes any difference, maybe in an accident it will help keep the engine from going through your fire wall... but doubt that was subaru's intention.

 

Putting the tire on your roof will cause more drag and decrease your fuel milage. The tire in your engine bay wont create any added heat, not any that would harm your motor.

If anything, it might damage the tire, being exposed to the high temps under the hood. I just have mine in the back of the Hatch (I lost the hold-down for the underhood mount), but that's a real bad place to be in a wreck. Once I get the lift done, it'll get it's own swing mount on the rear.

With the crummy roads around here, I keep a full size tire in the engine compartment and the doughnut in the back of the wagon--with the umbrella, lol.

hi

i put mine in the trunk.

no heat and the engine have more space of cold air or better air vent in the engine.

As do I. Found a nice vinyl spare tire cover with a cherry spare in it from an old XT in the junkyard. I'm sure it wouldn't stay so nice if it were under the hood; plus it puts some ballast over the rear tires for better handling.
