Would it be feasible/possible to put nitrogen in tubular tires to prevent day to day pressure loss. I've used it many vehicles from truck tires to ultra low profile high performance tires and it worked very well. Any reason why it wouldn't work, downsides?

If it matters, I ride Veloflex Extreme 22mm

I ride about 40 miles a day and pumping up my tires everyday is a real hassle.
