so the car has falken 451s all around.

my rears are bald though...the fronts have some good life.

i was thinking of getting the 452s for the back ( 255/35/18 ), and leaving the fronts with the 451s.

will this cause any handling problems?

i guess it should be noted i like to do canyon runs up out in malibu

The real problem will be if you have mismatched tires on the front and rear. If you go with a wider tire on the rear and don't change the front it will increase understeer. Plus depending on the width and offset of the wheels they could rub.

i have volk te37s on right now, for about a year.

18x7.5 front, 18x8.5 in the back.

225 up front, 255 in the back.

no rubbing front or back...and i'm going with the same tire sizes.

the only thing i don't know about is if the different tread on the 452s in the back will have any noticealbe effect on the handing.

found the answer to my own question. The 452s were designed to replace the 451s and st-615s without having to replace the fronts if you already have one or the other mounted:

"NOTE: This tire was designed to replace both the Falken ST-115 and FK-451. Therefore you can match two new FK-452's with two of your existing ST115's and FK451's, no need to replace all 4 tires. Just be sure to mount your new FK452's in the rear of your car."
