When I bought my bike it felt a bit squirmy and checked the pressure as soon as I got home. Sure enough, I was about 30 psi front and rear. These stock tires are some of the most sensitive I've ever ridden on for changing the way they feel and respond with tire pressure changes. The only air I've lost since that initial fill has been out the stem when I check the tires. I check them every weekend 'cause you just never know.
