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

Tire PSI (Day 2)

Yesterday, I reported that I have been riding for awhile now with under inflated tires(60 PSI) due to lack of knowledge. But when I got the advice I needed from BF, I went home pumped em' up to 130 in the rear and 120 in the front (I'm 210#), the bike felt like a magic freakin' carpet. I noticed a HUGE difference in speed and energy transfer. I was even able to ride the drops for a few miles Thanks!!

YES! You have now discovered the magic of high pressure. Use it wisely, as with great pressure comes great responsibility...or something.

Didn't you say you were running Conti's? Max psi is 120 on clinchers usually. I'm 235-240 and run them at 110, which seems to be the best balance for me. Just saying you may want to lower the dose on longer rides, as 130 should be quite harsh.

Take a look around and notice how many people are pedaling with under inflated tires. A lot!

One consideration: on rough chipseal, lower pressure is faster. If the road is irritatingly rough, then you are running too high of pressure and wasting energy.

Most times though, higher pressure is better.

i agree with BetweenRides, that 130psi and 120psi is too high for Continentals, even for a 200+ pound rider. i would suggest either running both at 115psi , or run the rear at 115 and the front at 110, to get the best contact patch...

the max for Continentals is 120psi, and if you go there you're cutting it close, i'm 190# and use the 115psi/110psi method because it works best for me...

Cool, I will lower the pressure and see how that feels. Thanks

Contrary to logic, you might even want to use less than max pressure if you're a heavier rider. Your weight will compress the tire and raise the pressure on its own a little anyway. The bulge in the tire is a fact of life, unless you get a super high pressure tire or weigh 120 (like I did when I was in high school). I would try 110 as mentioned above and see how that feels as well, then choose what feels best, but not going over the max.
