Yes I do check for Proper pressure every morning or two (never more than two days between pressure check since my flat last season was due to an underinflated tire, got my lesson there) and I alway keep 105-110 psi in the tire. In fact I got 5 punctures but one was my fault because I left debris in the tire after the first puncture so it punctured 10 kms further. For the rest It's alway small pebles that I find in the tire. I can't be THAT unlucky !!!
