Wife can't pump tires to 120 psi. Solutions?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Specialized make a hand pump that is used for pressurizing forks or pumping up tires. It has dual pistons and is good to 250 PSI. She can pump to 80 or 90 PSI easily on the big piston and then switch to the high pressure piston. 120 is a snap with the pump for any woman.

120 psi is way too much for that skinny wife's tires unless she's riding a 70lb bike.

Bigger barrel = larger piston. psi being pounds per square inch, the bigger the piston the more force you need to put on the handle to move it. She'd be best off with a small barrel, only problem there is she'll have to pump it many more times to get to the same pressure.

My theorising says the opposite. If the barrel has 1 sq inch of cross-sectional area you need 120 lbs of arm strength to generate 120 psi. If the barrel has 0.5 sq inch of cross-sectional area you'd need 60 lbs of arm strength to generate 120 psi. The smaller pump would take more strokes but requires less strength.

EDIT...curse you propagandrew!!

Tell her to stand over the pump and use her whole body weight to force the handle down.

Nah. I'm 5'9", weigh 135 pounds and I pump to 120 psi just fine on a $19.99 Blackburn pump from the Sports Authority. I don't work out. My upper body strength is probably below-average (it's all below the waist!). But if you use your weight properly, it should not be a problem.

Regardless of what you weigh, effective use of a floor pump is all about proper form.

Why don't you take some photos of her pumping up her tires, post the photos, and we'll have some fun critiquing her tire pumping form.

125 pound male here. I use a Serfas FP50. It's got a skinny little barrel but I can take it to 120 and above without a problem.

floor pump

Have your wife try the Park pump, the top of their line. It is designed to be easy to pump at every tire pressure.

90 psi in a 23 mm tire would probably be good at her weight.

Hence, Silca Track Pump. Relatively small barrel, and it will let her get the pressure as high as she could possibly need.
Besides, the Silca Pump will last for a lifetime, and its made of COlumbus tubing so it has some cache (at least to he steel is real crowd).

Way to go bro! Wives are good at some things and not others. You have to know your wife’s limitations.

Those foot pumps are horrible. They have a huge barrel which means that one would have to use incredible amounts of force to pump up a tire to road bike pressures. Also, the thin metal arms that attach the foot pedal to the pump WILL bend sideways.

Useless for anything other than 30 PSI mountain bike tires and pumping up basketballs.

I hope you mean deflate the tires on HER car! Then she'll be motivated...

100 psi is fine no reason to go any higher. Problem solved.

Nothing beats a few quick squirts with a compressor - 120psi in a matter of seconds!

Since she rides a bike, I imagine pumping a pump with her legs would be no problem. I used to have one of these and it is so easy to use since you use your legs which are much stronger than anyone's arms. What can you leg press? vs. what can you bench press?

You're nuts thinking the arms will bend. Only the really lousy POS one's from Wal-mart bend. They don't sell the high pressure pumps.
