if it did it would be such a small an amount i don't reckon you could measure it.
Helium atoms are much smaller than the combined nitrogen and oxygen atoms that form air molecules, so tyres filled with helium are likely to deflate much quicker than if they were filled with air.
Consider a helium filled balloon, despite usually being made of foil, the balloons never last more than a day or so.

ballon sellers have a trick nozzle that mixes 50/50 helium and air
It would be a tiny, tiny amount (and helium is pretty expensive).
IIRC, Porsche filled the spaceframes of some of their race cars with helium. Not to reduce weight (although you'd wonder why they didn't use something else, Argon, maybe, or even Nitrogen) but so they could, by measuring the pressure, tell if the welds had cracked. There were (maybe still are) some pretty crazy people working for Porsche.

What If you went over a hump back bridge really fast would you land on the ground further away? .......just like ET and the bicycle flying past the moon?
