700x23 Tire pressure

Lionfish said:

I'm running Huchinson Quartz kevlars. They recommend 110 psi max. I weight 228lbs. I regularly inflate to 125lbs with (so far) no problems & they roll ALOT better. No flats (so far) or traction/wear problems. Does anyone else overinflate like that? Anything I need to worry about such as blowouts ect? Any & all opinions/facts are welcome here.

If you ride on smooth roads, at your weight that should be fine. Since I weigh about 80 lbs less than you, I actually run a little less than the recommended pressure because the ride is more comfortable and I get less skidding on rough pavement.

Overinflation not only puts you at more risk for a blowout, it also may result in slower speeds. Best to stay within the recommended pressure range. There are many threads that have more than adequately discussed this topic.

Man, you might as well ask everyone's religious beliefs.

I used to always use 120psi or so, but a few years ago I started backing off from that. Today my wife and I (who combined weigh a lot more than 228 lbs) run 100 psi front and 110psi rear on our tandem (700 x 28c tires). My subjective feeling is that the bike as well as it ever did and rides a lot more comfortably but I don't know how to measure either.

I'm sure there are folks who have contrary opinions.

You sure about that? I thought underinflated tires are under the risk of blow outs due to the tires slipping off and the tubes sneaking out.

That doesn't seem right. Under infaltion tends to allow more pinch flats, and higher pressure generally leads to less rolling resistance, hence higher speeds but a harsher ride. Then again, I could be all wet. 🙂

That's true, but only to a point.

To go fast, you have to keep putting power to the ground. Rock hard tires bounce around on all-but-perfect surfaces. Every time your back tire bounces off of the road surface (and it does) you aren't putting power to the ground.

Who said to underinflate the tires. I suggested staying within the recommended range of inflation. Thus one should not underinflate or overinflate. The thought that overinflation results in faster speeds is simply overinflated thoughts without merit!

Lol.
