An overall larger diameter tire will change the final drive gear ratio somewhat. The car will not "Pull" quite as strong and will turn less RPM at any given speed. You will be going faster and travel farther than the speedo/odo are registering, so your mpg checks will calculate low. Kip |

I have a 2007 EX-L. What pressure should the tires be inflated to? The low pressure indicator light is on and the manual says 32 but the tires say max pressure 44.

The idea is to have the proper pressure to allow the entire tread (width) to be in contact with the road, and the sidewalls to still be flexible enough without "folding" on curves. Excessive pressure will result in the tire "ballooning", putting more vehicle weight on the middle of the tread. This will wear the center tread faster than the edges. Also, because there is less of the tire touching the road, handling will be affected. High pressure may increase MPG a bit due to less rolling resistance, but at the cost of handling, safety and uneven tire wear. Insufficient pressure will allow the center of the tread to recess somewhat, and more weight to rest on the outer tread, wearing it more than the center. Result may be poorer MPG due to the excessive rolling resistance, sloppy handling due to the side walls being too flexible on curves and such. And, of course, uneven tire wear. All that to say the tire is capable of safely carrying 40# of pressure, but Honda recommends 32 under normal conditions. If you should load her down with 8 people and hook a 3000# trailer behind, the tires would sag a bit and the need for more air pressure in the rear is real. The only way to be absolutely sure of the correct pressure for your car is the "Chalk" method, using a tire gauge dedicated to that car. Interesting that our "Pilot" gauge shows 33# cold pressure to be proper for the Pilot. That gauge is the only one used for that car. The CR-V gauge shows 28# to be proper for the CR-V. Gauges can vary a few pounds. With a given tire pressure, one gauge might show say 33# and another gauge may show a couple of pounds more or less. When the Pilot has proper pressure (33#) according to it's gauge and I check the Pilot tires with the "CR-V" gauge, that CR-V gauge will show 35#. I don't know which of those gauges is the most accurate. And it doesn't matter. "Chalk" shows proper inflation to be as described above. As long as I use the gauge dedicated to that car, I'm good to go. In reality either gauge will put either car close enough.  Kip

Replying to: justaveragejoe (Nov 10, 2007 7:03 pm) Most will agree that the entire width of the tread should be on the road. With that in mind, over inflate the tires a few #. Don't over do it! Drive around for a few miles until you figure the tires to be at operating temperature. This should be done with the "Load" normally carried in the car. I generally just check the two on the driver side as I am usually the only occupant. Pull over at the beginning of a straight flat stretch of good smooth road and put a chalk mark across the tread in 2-3 places. Ease back onto the road and drive a mile or so. Check the chalk marks. You may find that the center is worn off while the edges still still have chalk showing. If so, let a little out ( say a pound) and continue this madness until the chalk wears evenly across the tires. Go back home and let the car sit where ever it would be when you check your tire pressure. Allow a few hours for tires to cool. Now check the pressure. At that point that tire is inflated correctly for "COLD" pressure. The gauge reads that pressure. Next time pressure is checked, check em cold and use the numbers you developed with THAT GAUGE ! NOTE: You could probably run a couple of pounds lower and still wear the chalk evenly. However since we are concerned with mileage and safety, we might wish to run as much air as possible to keep down rolling resistance, while keeping the tire at proper configuration on the road. Disclaimer: I got this off a web site a while back. Seems to work good for me and makes sense. Might not work for others. Kip |

We run 38 PSI on the Goodyear OE tires. BTW, they are junk.

I have a 2005 Pilot and live in update New York. I have narrowed my choices to: A) Nokian WR S.U.V B) Michelin Cross Terrain c) Michelin LTX M/S All are around the same price, Please Advise |
