speaking of tires..............I'm standing there looking at the tires saturday and thinking to myself. "Self" these suckers are too underinflated. So I read the tire data.....ST 205 75R 15 Load Range C....max psi 50 lbs. Ok, I know what all that means.....so I am still thinking to myself......"self" Why are they so dang compressed? No wonder I have so dang much drag when I slow down.....So today I am searching the internet and checking to see who manufactures a D range or possibly even an e range tire in that size.......bzzzzzt wrong answer. So, does anyone know of a D range tire? Has anyone had issues with their C range tires? Has anyone made any significant tire improvements, i.e. rims size? Am I just overly concerned, need to chill out, and have a beer?
