What is the ideal tire pressure for 175 lbs rider?

There's some debate and discussion, but I'd say 25psi front/28psi rear. You don't want to inflate them over 30, measured when tires are cold.

I keep mine around 27. 30 (recommended) makes the road really harsh. Anything below 25 it starts to feel sluggish.

Ericcalm, thanks for the info. What would you say for a 240 lb rider? Does your formula go up or down?

Thanks, Ed

The theory behind keeping the front tire @ a lower pressure than the back one, is that if you hit an object in the road, the front tire absorbs the shock better, and won't react as severe as it would at a higher pressure.

Did that make sense?

I'm not sure how much it would really change. Try starting at 25/28 and see how they ride. Some of it is comfort and feel, but at a certain point you're risking a blowout, slide or other problem by overinflating. I can't say precisely where that point is... and I'd like to avoid finding out firsthand.

I have only put 60 miles on my Buddy and had it just over a week. Yesterday - I noticed the ride in general felt different, a little slow and slightly 'wobbly'. After I got home and let the tires 'cool' for a few hours I checked to tire pressure and both the front and back seem really low... front was about 22 and back about 20 - which is odd.

Is it normal to need to fill the tires weekly? I have a pump with a gauge built in, so it isn't a big deal, just curious if this is expected or if maybe I have a problem.

heavier rider more psi.

im 250 with my gear on. i run 30 lbs.

low psi can lower mpg

The rear tire requires higher pressure because there's more weight over the rear wheel.

If you have temperature changes, both up or down, the tire pressures can change on you. I almost always check my scooters' tires before using them, and the Buddy's usually remain good for several weeks at 24F, 28R PSI.
I weigh 220 (dressed) and I find these tire pressures just right for me, not too harsh, not too soft. Just right...!
