tires are always going flat
I bought a set of the CS4's in October and I can't wait until Spring when I can replace them with Michelin's. I have taken the tires back to the dealer over 25 times for the same issue. They are constantly loosing air pressure and going flat. I replaced my valve stems thinking that the issue was with those, but its with the tire, they do not hold pressure. It's never just one tire at a time I have had to stop and put air in all 4 at one time before.
