i have a 2009 5dr ford focus with an odometer reading of aroung 82k km.

i have replaced all four of my tires once with the same OEM brand tires (goodyear). i noticed though that my front wheels are worn out again -- so i rotated them to the rear for safety.

two questions:
1) is the rate my tires are wearing out normal? or too fast?
2) i am thinking of changing my tires to another brand. any suggestions? riding comfort and control is of utmost importance. budget preferably should be around or near the OEM brand pricing.

thanks.
