Many road cyclists (myself included) like to "rotate" our tires, when the rear is worn we move the front to the rear and put the new one on the front. That makes using the same width tires more important.
But as I stated, there is no harm in mixing it. YMMV.
Another small question about rear tyre , my rear tyre indeed just start to crack , i need to replace it , but i can't find same brand , front tyre is still in very good shape , not sure if it's better to buy new set , or just buy one tyre for the rear that's different brand/pattern , etc ..
I feel it was a food idea to always buy spare tyre when buying a tyre-set for such circumstances
