taal2020 Posted March 27, 2013 Report Share Posted March 27, 2013 Guys, I have Michelin Tires (P245/60R18 104 T). What is the ideal tire pressure when filling air? Please suggets Quote Link to comment Share on other sites More sharing options...
omar302 Posted March 27, 2013 Report Share Posted March 27, 2013 Manufacturer recommends 35 PSI. I believe the TPMS comes on at around 28 PSI. If your driving high speeds, it is better to go for 35 PSI. If your driving in the city, with bad roads like where I live, I would suggest 30 PSI & the TPMS will not come on.

taal2020 Posted March 27, 2013 Author Report Share Posted March 27, 2013 I have read in some of the sites that, having 38psi will increase the mileage...but could lead to tires getting worn out more quickly... Quote Link to comment Share on other sites More sharing options...
Waldo Posted March 27, 2013 Report Share Posted March 27, 2013 There is no ideal pressure. The ideal pressure is different for everybody and their unique driving conditions. Higher pressures will give you better mileage and often better steering response. But higher pressures will cause uneven wear, they will make the ride harsh and they will reduce the amount of grip which increases the stopping distance and makes the vehicle less capable in emergency handling maneuvers. Too high a pressure (above the max rating on the sidewall) can cause tire failure. Lower tire pressure have generally the opposite effects as those above. However most people don't consider the load capacity of the tire. As pressure goes down, the load capacity also goes down. Once you exceed the load capacity, you run the risk of tire failure. Since OEMs don't specifically call out the lower limit of the load capacity of the tire, one must assume that the OEM tire pressure is the lowest you can safely go. Running anything below the recommended pressure is a safety risk. Running your Edge at 30psi around the city in reasonable weather is probably fine, but running it at 30psi while driving across Arizona in the summer with a family and full load of luggage would be pushing too close to the limit for my comfort.

NatG Posted March 29, 2013 Report Share Posted March 29, 2013 From my experience, it's best to go by the tire. I have the Michelons on my Edge. MAX cold PSI is 44. So When they are cold, I fill between 38 and 40 PSI. I find the shape of the tire is best at this rating, it sits nicely on the ground, and the ride is better than lower pressures. I do not drive super aggressively, and I have about 37,000 on the car with a pretty generous amount of tread left (original tires). Make sure to Rotate regularly.

Feirstein Posted March 30, 2013 Report Share Posted March 30, 2013 Start with the recommended pressure. If driving with a full load while pulling a trailer, then add several lbs. If driving over 90 mph for an extended period add a few lbs. But the recommended pressure, around 35 lbs is recommended for normal use. Don't run lower pressure than 35 lbs.

Edgieguy Posted April 1, 2013 Report Share Posted April 1, 2013 I run my 22s with 38lbs of nitrogen. My Sport consistently gets into the 21mpg range with a 50/50 mix of driving. Quote Link to comment Share on other sites More sharing options...

I prefer a Nitrogen/Oxygen blend (roughly 78% Nitrogen, 21% Oxygen). 1 Quote Link to comment Share on other sites More sharing options...
Dingo Posted April 1, 2013 Report Share Posted April 1, 2013 Kirby, I figured you'd use butane. Quote Link to comment Share on other sites More sharing options...

MFdad13 Posted July 7, 2013 Report Share Posted July 7, 2013 Why would you go by what the tire states? That is the pressure you would run at full capacity. Always go by what the door placard says. Quote Link to comment Share on other sites More sharing options...
2011edgese Posted January 30, 2014 Report Share Posted January 30, 2014 Mehhh... The door says 35 when cold. I took a tip from someone that said to drop it 3 or 4 psi to make the ride smoother. I dropped it to 31psi all around and noticed a audible growl noise later. Put the pressure back to 35psi a month later and now the tires howl in the freeway. Be careful.

2011edgese Posted February 17, 2014 Report Share Posted February 17, 2014 (edited) Now I'm at 39psi since my tires day max is 44psi. Just to get rid of the howling at certain hover mph.lol I rotated the tires to see if I could quiet them. It's worse now. Lol. Turns out, performance ties that are directional are notorious for boar due to the tie grip pattern wearing at the edge causing the howling.
