How much air do you pump into 700C bike tires? They are on my Specialized Women's Globe Carmel 1 bike.

    The tire pressure range will be in raised numbers on the side of the tire! Look for it there 90-120 psi somewhere in that range. Its there!

    The psi should be printed on the sidewall of the tires.

    You want to pump them up to the pressure that is stated on the side wall of the tire. Start at a few pounds below the max ratting on the tire. Your weight and tire pressure will determine how the bike rides and handles but you want to stay in the range that is stated on the tire.

    The max pressure is embossed on the tire's sidewall. I always pump up my tires to the max pressure. This reduces rolling resistance and also gives you the maximum protection against pinch flats. Some people back off the max pressure a bit. Try a few rides at the max before you do this. Then, back off 5 psi at a time. Don't back off more than about 10 - 15 % of the max pressure.

    Check your tire pressures often. Pressures can drop 10 psi or more overnight. Personally, I check tire pressures before every ride. With a floor pump, it just takes seconds.

    The side of the tire will tell you. Mine is rated for 100-120 psi. A big dude like me needs 110 on the front and 115 up to 120 on the back. So, in other words if it gives you a range and your a bigger person use the higher PSI.
