Tire Pressure

I use 42/40 and saw a jump in mpg. Been thinking about going to 44/42.

I run the stock Integrities at 45psi but don't mind the stiffer ride. Increase the tp a little bit at a time as long as the ride is still comfortable.

I run 44psi front and 42 rear in the standard 195-60H 15 Michelin Energy tyres. Ride is fine 4.3L/100km but a little noisy at speed on some surfaces.

I've been running 42/40 for the past 6 months or so, and am right at 51.5, with 99% freeway driving between 65-80 mph. I have 0ver 42,000 on the original Goodyears, and the tread only looks 1/2 worn. I know there is lots of whining about the OEM tires, but I can't see changing them until they are gone, and mine don't seem to be going away anytime soon. High pressures are better for the tires, than too low (factory recommended).

42-40 since the day after purchase summer of 2006. stock tires have worn very evenly, but are now worn out. now i need to shop for new tires before winter sets in..........

I have an 07 that I bought in May and just started reading on PC since 18 Sept and Have noticed people talking a lot abought getting a certain amount of miles per tank and MPG. I have read enough about the tire pressures that today I went out and checked what my dealer had them set at and to my surprise I had 28psi in all four wheels! I have been averaging around 45 with this set up and I have also been getting around 525 miles per tank and have never seen the last pip on my fuel guage blink? Usually I put around between 10 and 11 gallons in when I fill up. Be advised that if you leave the fuel nozzle in after the first click off of the fuel pupm you are risking the fuel tank puking all over you. Best way to get a "real" fill up is to remove the nozzle after it clicks off and then while holding the nozzle loosley in the tank opening slowly fill the tank till you see the fuel at the top of the filler.I have also got a high of 55.9 mpg on a trip we made in June shortly after buying the car. I just put 38/36 in my tires and can't wait to see if that makes any difference in mileage.

44/42 here. I just rotated mine at 10K miles and didn't notice much wear to speak of. If anything it appears the edges are getting worn more than the center of the tread, which is normal I believe. I imagine the edge wear would be quite a bit worse at lower psi. I haven't noticed any problems with it riding too stiff or anything like that and never had any passengers complain (even my wife who certainly would let me know if it was a problem).

is it best to inflate tires after they are hot from driving, so you know that when you put 44 psi they will not increase in psi?

I believe you should fill them up after they are cool all the way up to the max sidewall pressure or whatever psi you choose. So in the mornings after the tires have cooled down should be the best time to inflate them to the desired psi.

I concur. The max psi listed on the sidewall is for a cold fill and includes a factor of safety for expansion under operating conditions.
