I decided to ride my bike in the woods, just a lazy ride on the trails now that we've had a little rain so I just unloaded my bike from the hitch rack and went riding. All was pretty good until I went into my little river section and found I couldn't get out. It has been dried up all summer so initially I didn't connect things and just blamed it on my lack of experience, that the hillside was now a little muddy instead of dirt and my tire is really worn. I had to push the bike up the hillside because I just couldn't ride it out. I always put extra pressure in the tires when transporting it on the hitch carrier and didn't feel like taking the air out. I just wanted to ride. Well it turns out 10 psi in the rear tire (and 12 in the front) isn't helpful for much of what we do. I'm going to try again today with the lowered pressures. edit: Ok, so a little less wet today but I made it up the hillside with no issues at all. I'll try again when it is really wet to make sure but the tire pressures definitely seemed to make all the difference. Duh, it should!
