ok let me start by saying i did a serch before posting this but did not see anything.

i need new rear tires but i don't need fronts yet. i've shopped around and listened to the board and i wanted to purchase some kumhos. for the price difference, i decided to go to the local discount tire ($194) vs. buying from tirerack ($174). when i stopped in, they told me they had some yokohamas in stock that they needed to get rid of so he's discount them $80 off the regular price. they would still be more than the kumhos but not by much. research indicates they are a much better tire. ok here's my question. when the fronts need to be replaced i probably won't buy the yokos that match because of price. has anyone mixed tires front/rear and is there/will there be any issues in doing so? i will remain stock size both front and rear. thanks.
