Previous Thread Next Thread Print Thread Rate Thread air pressure and mpg #677198 12/15/05 08:36 AM Joined: Sep 2002 Posts: 481 Tennessee taro OP Mudrunner I went a little long on my last tire rotation and noticed that the middle of my front tires were almost bald while the edges were not as worn. The rears looked fine. When I rotated them, I lowered the fronts to 28 pounds hoping to even out the wear while keeping the rears at 35. I noticed tonight that my mpg dropped from the 14s to the 12s. Could the drastic drop be soley to the air pressure drop in the front tires or might there be something else going on? Thanks, Taro Re: air pressure and mpg [Re: taro] #677199 12/15/05 01:25 PM Joined: Apr 2003 Posts: 898 Dallas, GA litnin Rock Warrior Yep, it sure could. Wearing in the middle indicates you have way too much air pressure in the tires. Relieving some of that air pressure to put more contact patch on the ground, increases rolling resistance which will reduce fuel mileage. 1995 Trooper LS auto 3.2 DOHC /w SOHC intake 1989 Trooper 2.6 auto 1989 I-Mark RS DOHC 1.6 1991 Stylus XS DOHC 1.8 Re: air pressure and mpg [Re: litnin] #677200 12/16/05 05:53 AM Joined: Sep 2002 Posts: 481 Tennessee taro OP Mudrunner Thanks for the reply. Gas is starting to go up again. I've been riding my motorcycle most days. If I go ahead and get some heated gloves, I think I'll be alright even down into the 20s provided there's no precipitation.
