I just recently came into possession of an older K2 road bike, needed a little TLC but I got her all fixed up. This was my first ever road bike, I had mountain bikes when I was in my teens but once I got my drivers license that was the end of that. Now Im in my 30's and wanting desperately to get back into better shape.
Well I went and took it out today, checked the tires before hand and put air in them and a new tube on back. The tires say 110lb of PSI (not a range of pressure but a single number), I guess thats normal but for some reason I felt scared to put that much air in and stopped around 90 or so. I don't know the condition of the front tube and the rear I was worried about it pinching and not seating correctly since it was the first time I ever replaced a tube.
I took the bike out of a few rounds around the block, riding on the street for 3/4 of the way (their backroads, relax) but the main road forced me onto the sidewalk and MAN that is a hard ride. I know my mountain bike when I was younger had not only front suspension but I'm positive the tires had pressure nowhere near that high.
Should I put them up to the recommended 110 PSI or is 90ish ok? I only weigh about 145 so Im not heavy on the tires at all. They are hard as a rock and don't deflect at all when I'm on it. I know lowering the pressure will make the ride a bit softer at the expense of rolling resistance, but is it worth it?
