Tim Tebow's Pedicure -- Hey Coach, Check Out My Toes!

Tim Tebow clearly knows how to impress his new boss ... cause the NY Jets QB went out and got himself a pedicure in L.A. this week.

TMZ obtained a pic of Tebow in the chair at MB Nails in West Hollywood on Tuesday ... moments before technicians went to town on his fingers and toesies.

Sources at the salon tell us Tebow was "VERY friendly" during his $23 mani/pedi treatment ... and dropped a HUGE tip at the end.

Manicured feet are important to pro athletes ... especially when they're playing for Rex Ryan.
