I am considering getting these tires in size 225/45/18 for the fronts only since the rears are still new. My question is, is it okay to get these even though the rears are different brand (Yokohama AVS ES100)? The Kumho's has treadware of 320. How much estimated mileage can I get from them?

 

They are a decent cheap tire, if you can afford it upgrade to toyo proxes
T1R's.

 

its ok... i got Ecstas in the fronts...
and freaking Michellin Pilot Sports 2's in the rears... (that was a GRIP of money) esp with the size rims i got

 

I'm running those tires in the back (275/30/20). So far so good. I hope I get more than a year out of them. My last tires (Toyo T1) sucked in terms of tire wear.
