Yep. You get more points if you start on dodgy FRONT tyres.
Be aware though that you can switch between tyre grades but not between tyre TYPES when you pit. If you start on "Normal" tyres, then you will only be able to use "Normal" tyres for the rest of that race - but can use any of the three grades within Normal that you have purchased for the car.
Note that when you pit and try to switch from Normal to Sports it does claim that you've changed, but this is not borne out by laptimes or wear rates.
