The the tread on my front tires is visibly worn (not much tread in some areas) on my vehicle, and they need to be replaced. The back tires are fine, and had been replaced much more recently due to a chunk being taken out of one of them.
The model of tire of the back tires (HANKOOK OPTIMO H724, P175 / 70R14 - 84T) is no longer available for me to purchase. However, a similar tire, the (Hankook Kinergy S Touring H735 - 175/70R14 84T) is.
Is it safe to replace both front tires and rotate with these two different models of tire?
