fred and "smiley" to do 300 mile tire test

although i love and admire john 1701a as THE prius guhru im still going to try a little test. i have been running 42f and 40r for the last year im now going to try the official tire pressure recommended by factory and located on the door of "smiley". i sometimes leave nashville to "invest" in metropolis il on the riverboat. normally i average between 44 to 47 mpg at speeds from 68 to 70. for some reason i get 47 plus on the way back. probably because my wallet is way lighter! or for the reason that im going slightly down hill (not sure). speaking of hiding money i use the sunglass space above the mirror so i dont walk around with a wad of cash. anyway the round trip is almost exactly 300 miles so well see if i get the ssame or less with the lower tire pressure. ill let you know sunday.

 

you are right dan. see my part II entry on the forum. i probably will go a little higher in pressure like 38/36 but im not feeling the need to be at 42/40 anymore.not unless the suspension was a little more aggressive

 

yeah i think the 40/38 is fine but im going for the compromise. i normally like stiff cars but ifeel im just getting stiff tires at 42/40 and not getting a lot of bang for the buck. im still a car guy so ifa prius based 2 seater sportscar comes out. im in!!!(still have to get the killer mileage, though)

 

you know, dan you actually hit an underlying concern of mine during this past year. i mean im not really concerned that the tire is being unduly stressed at 42/40 but it just "feels" a little much. let me know about your new pressures. its strange but its almost like doing a weight lifting training. you kind of adjust this a little and do this alittle more or this alittle less until you feel comfy
