archived 33mpg over the past weekend, drove from MD to CT avg 70-75mph with A/C ON. 3 ppl in the car (including a 2 yr old), 36.5 PSI all tires.

I have to say what a great highway cruiser!!

Now only if Acura can put on some better brakes. My front rotors wrapped again, will dump them this time instead of re-surfacing. Bought brembo blanks and ceramic pads, waiting to be installed.

thats pretty good-
you may want to run tires a few psi more next trip- the extra weight in the car and extended hi speed driving...
Have you seafoamed?

acura_fantacy

Not seafoamed, just a K&N drop-in air filter, running M1 5w-30 if that matters.

Kicking up the psi helps? How much, if so? I run the recommended 35psi front and 32psi rear.

how much is the psi supposed to be if your just city driving usually with only one or no passengers

totaledTL

Should be a sticker in the door jamb, or check your O/M.

i remember it said like 32 or something but isnt that kinda low the max psi on the tires is like 50 or 52 psi

totaledTL

That's probably the pressure required at the maximum load rating for that tire.

I know that the higher PSI in the tires will help with rolling resistance. People who hypermile use like sometimes like 60 psi just to get 1 or 2 mpg more. If I am just going on the highway and want good MPG I put about 38 psi.

do not exceed the tires psi limit. it will say what it is on the side of the tire. i run 39-40psi in all my tires, got 31.67mph a few days ago. 80%highway, 15% city, and 5%standing in traffic. i get over 29mpg on 87octane. no problems running 87

i usually run between 39-42 all the way around with a preference of 40 and i get 23 mpg all city. got 32 mpg a couple weeks ago all highway.

Higher PSI yields better gas mileage, the ride will feel stiffer/rougher too. keep that in mind. Personally I wouldn't put anything more than 40psi just in case the tire blows up. Be sure to check tire pressure in the morning when it's still cold.

I usually do about 4-5 psi over what the door jab says, in my old Accord, I kept it at a steady 40psi all around and got incredible gas mileage.

Too much & the tires will wear out quicker in the center.

i guess thats true, but you would have to put so much pressure in that the tire would be shaped like a bowl.

i know my tires are low, prob around 29 psi - not cool. i think i am going to fill them to about 38-40 psi.
