So, it's time to replace the rear. My fronts are still fine and i don't have the cash to do all four at the same time anyway.

Currently I have the BFgoodrich G-force sport (got the AP1 used form a dealership and it came with these tires)

measurments are:
F: 205/55/16
R:225/50/16

I checked to see if these come in the 245/45/16 but they don't.
So my question is.....would it be ok if i put different kind of tires in the rear and leave the front as is? Also, I'm looking for something with great treadlife.
Any help would be greatly appreciated.

Edit: BTW, i do aggressive driving and would like tires that are track worthy (or at least auto-x)

keep the front and back tires the same! Don't mix brands. If you are going to upgrade do all four at the same time.

Especially if you are driving aggressive or tracking

 

they dont come in 245/45/16
