The tyre will get bigger, because of heat, but so will the wheel it sits round.
BTW, steel will change 0.0011% in length for each degree, so 20 degrees on a 20 inch diameter tyre is about, well, as engineers like to say - zero.

I'll just get my coat.

Since we were getting all technical about gas laws and Kelvin temperatures, I thought it should be pointed out that the gas is not contained in the same volume all the time

Fair enough.

Best wishes all,
