2005 prius here.. 97k miles..After putting on new tires..was told are grt and fuel efficient.. gas mileage is off between 125-175 miles a tank.. had the tires checked no leaks, etc perfect condition.. monitoring the psi and it flutuates a bit.. but that shouldnt b the prob.. plz help i drive a lot for work..
i don't understand what 'gas mileage is off between 125-175 miles per tank. can you convert that to mpg? what are you comparing it to? how long have you owned it? how many miles on her? exactly what make and model tire? is the maintenance up too snuff?
It's a funny thing. I haven't had my '05 G2 for long. I'm finding that I get the best milage when I just drive nicely and don't look at the electronics. Now I'm not sayin' ... I'm just sayin' ... just drive your car for a while and let things (new tires) settle down. Thinks are much nicer when you don't worry about them.
I can be the problem if you are fluctuating towards being under-inflated. You are running recommended pressures of 35 PSI front and 33 PSI rear, aren't you? If under these pressures, you will not get good MPG.
That makes sense I guess. Tires can make a big difference. Once you determine the make and model, we can do some more investigating. Not only do you need low rolling resistance tires, but there can be a break in period
