However, I have yet to see a thread about what ecomodders run in their tires. Please post how many PSI, what sort of tires, and how your inflation compares to the sidewall max.
In my Mazda, I run 48 PSI in the front tires (Michelin Harmony, rated at 44 PSI) and in the back, I run 42 PSI (some off-brand Hercules tires, with no rating listed).
I recently jumped to 48/42 from 45/38. Based on my last few tanks, I think it's likely that the extra few PSI helped my fuel economy. |
I run recommended inflation pressures in the truck for regular driving (32/35 psi).For open-road high-speed interstate travel,I bump them up 3-psi,as per Toyota's recommendation.--------------- For the CRX,I run 44-psi,which is the max inflation pressure for those tires.Rides a little rougher but no issue for me.
