Short answer no. 

I've had a spare wheel still with the sticker on the tread since the 1980s and it still looks like new. It is in front of the radiator (which has its own ducting from under the front bumper) and there is ventilation between the bonnet and the bumper to the spare wheel. I would think that cars like the Citroen CX which also had the spare in the engine bay but up by the screen would have been more likely to suffer but I never kept mine long enough to find out, perhaps others can comment?

Thinking about it, there are a lot of other rubber components nearer the engine like cooling hoses and air pipes which last for ever as well.

A lot of Renaults and small Fiats have, or had, the spare wheel under the bonnet - not a problem.  Tyres get hot in normal use anyway.

Isn't this a major part of why tyres are rubber based, heat resistant? See also 'rubber' gloves, for kitchen duties.

I think it's UV more than heat that kills rubber

I had an 'end of life' Talbot Samba, the original spare tyre, stored under the bonnet, was the only thing on it that wasn't rotten.

Rubber will degrade with temperature increase but the composition of it can be varied - addition of antioxidants for example - to counteract the effects of heat. Many tyres get quite hot just through friction with the road.

That's at Woodstock man!

It's now the A44, and the building in the background is the Punchbowl.
