Hi. It's been a long time since I've posted. I'm just starting to use my bike again after a lapse of a few years. This time I'm going to keep at it, even during the winter. I'm fed up with being fat and unfit. I've already modified my diet, eating more healthy and counting calories, and I've started riding again as part of my fitness program.
I'm 55, 6 feet tall, and unfit. I weigh 232 pounds today. Six weeks ago I was 257 pounds. I'm riding about 50 to 60 miles a week now, and looking to increase that as I get more fit. I know that is not much, but at my current couch potato level of fitness, it seems like a lot to me. And it seems to be helping me to drop the pounds.
I have a riding partner who also has a weight loss objective. He is 40, 5 foot 6, and 148 pounds.
We don't know much about bicycling, and don't know much about our bicycles, but we are looking to learn. Hence the basic question about tire pressure.
I have a 2007 Trek 7.7 FX, Bontrager Hard Case Race Lite B 700x28 tires. He has a 2007 Trek Soho, same type tires, but 700x32 size. Those tires are both rated to max 125 PSI, according to the sidewall legend. We've been running 110 PSI in front and back tires on both bikes, but based on what I've gleaned from recent threads on this forum, I gather that running the same pressure regardless of tire size and total riding weight is not the typical approach.
So I'm wondering what PSI we should use for our weight and tire size? Should front and rear be the same pressure? What would be optimal? We ride only on smooth dry paved roads and paved bike trails, if that makes a difference.
We're not trying for ultimate speed, as neither of us are fit enough to go very fast at the moment anyhow. Neither are we looking for ultimate comfort, and we are trying to push our exertion to useful levels. The objective is daily exercise to burn calories. So we just want to know what pressure is "normal" for our bikes, tires, and our weight.
