Distilled or tap water?

Im not sure if it matters. As long as it is very hot water. Ya know so it dries faster

Tap water?! R u kidding me? Nothing but the top-of-the-line Motorcraft premium tirewater for my wheels. And don't even talk to me about the garbage that Quaker State sells; I'd rather get my water from Flint than QS.

Our '18 came from the dealer with 35 psi, and you could feel every pebble and every imperfection in the road. I put the psi at 32 psi cold, and the car rides much better. I'm not going to save enough gas at 35 -40 psi for me even to consider a higher pressure. Plus, as stated you'll be wearing the center of the tires quicker, and the cost of new tires will eat any gas savings up in a skinny minute.
