Zman, I have Yokohama Avid TRZ tires on Civic and xB before. They are very good tires. I didn't make it to 40psi as the gas price is not like today. I believe it can handle 44psi, which is max on tire wall. Try it. If you don't like the ride, go back to 40psi. My experience told me 48psi with stock size is too much. The ABS activates a lot.(losing too much traction surface) By the way, 40psi to 44psi will give you about 0.5mpg. Automatic is good on freeway. At least, you don't have to reviv to 3000rpm for only 60mph.
Yeah I will try 44psi or 43psi. My tank is at 472.2 miles, I probably have less than a gallon left.
I get frustrated with the auto because on flat roads I have to go >40mph, hills >50mph, to keep it from shifting down. So in a 30mph zone, I can manage 4th gear at 35mph until I hit a slight incline and then it shifts down, and sometimes back up and down again! (cops like to hide here)
I may get some black duct tape and make temporary wheel skirts or something. I usually have a passenger and make many short trips, but hopefully rock solid tires can get my average to >40mpg!
