Fuel efficiency mods

[sickpuppy1]

Tires made for fuel economy generally just have a harder compound rubber to lower rolling resistance. the downside is traction...... in wet or snowy times they will slide easier. Not for me thanks. too many other areas effect mileage more to waste money on them. driving style, mechanical condition and pressure make up more fuel mileage more than tire compound.
Basically, dont waste your time or money on them. We have people in here using more sport compound tires getting 40 plus mpg. I'm using Hankook Optimo H727 because of treadwear and pricing and get 42 plus on the highway and get around fine in snow(up to about 4-5 inches) or rain. I used to keep them at 40 psi but have put them down to 35 cause I'm 60 yrs and getting to be a softy,lol. mpg went down by 1-2 when I did this, but I drive a work truck so my car only goes less than 50 miles a week now days.
