over inflate tires for highway driving
I was recently reading my honda owners manual from 1983 and it said that if you are going to be doing continued highway driving that you should add another 5psi of air to your tires above the normal recomended presure to prevent tire falure from over heating, and I thought that it was one of those ideas from the past, then I was reading a honda owners manual from 1997 and it said the exact same thing! for continued highway driving inflate your tires by an extra or so 5psi.

higher pressure reduces temperature rise in the tire at higher speeds because it reduces tire wall and tread flex thus less heat is produced in the tire

Congratulations!
You know, speaking of owner's manuals, the first page message is dwindling:
Most of them used to say, "Congratulations on the purchase of X Vehicle! It should provide you with many years of driving pleasure". Ford quit doing it, but I think Honda still does. It's funny -- I always have to pull out the manual and get that re-assurance. :p RH77 |
i wish my car came with a owners manual. :(
the glove boxx says 35 PSI in front and rear. should i increase thator leave it stock. i do 30/70 highway/city. also how much will the speddo be off if i overinflate? |

The speedo will not be off any more than it already is! Tire diameter does not change with those steel belts in there! 30 / 70 what? MPH? MPG? Besides, isn't this backwards? :cool: |

Alot of people, and OEM's do this.
If you'll notice, Toyota provides many vehicle platforms different specifications for different parts of the world. Specifically Europe. Where the starting tire pressure will be identical, but you'll see advice such as, "For extended highway driving, or driving above 90mph, run XXpsi. In the case of the Camry platform. For many years OEM was 32psi, and then recommended 38psi) |
I run 55 psi on the highway, and around town :D (35 recomended)
