Had Nitro in all my race car tires to 95%. Normally you have mostly nitro in the air and as don said about 79%. i tried Nitro in my coach tires for a year and experienced none of the same benefits you have in auto tires except keeping the insides dry. Problem comes up anytime you need air pressure in a tire. There are NO car dealers set up to do a coach tire. The coach weight is too much as in the process the tire needs to be deflated to the ground and reinflated. See my point ? It's a waste of money in a coach, but worth every cent in car tires.
