a 1995 sportage SOHC type is? I am curious because mine seems to be awfully low geared on the hwy. Its well over 3000 when running 65mph. Is this normal. What size bigger tires could I put on it to up the speed for the same Rpm with rubbing, etc. I have a Ford ranger with a 2.3 litre engine in it and weighs close to the same and in 5th gear there is an incredible difference between it and the sportage.
