tire pressure upgrade on 08 touring edition

fbret · 07-09-2008, 08:38 PM

I just filled up for the first time my prius :-)
I wanted to up the tire pressure to 42/40 as recommended on the board, but noticed the tires say "do not inflate over 40psi"...
what to do?

thats up to you fred but my tires are 42/40.

My 08 Touring #6 is at 42/40 psi. Has been for the last 5000+ miles.

It is not advisable to inflate tires above the maximum rating given on the sidewall. The 42/40 PSI front/rear commonly reported here applies to the non-touring Goodyear Integrity tires, which have a maximum rating of 45 PSI.

The Touring tires are sidewall rated for 50 PSI.

I've been running 50/48 for 4 weeks. I'm now trying 40/38 to see how handling improves and MPG deteriorates. I'm more concerned about traction and safety (and avoiding expensive collision repair bills) than a few pennies in my wallet today.

My 2008 Touring Package 6 has the 41 max tires. I inflated them to 41 all-around without a worry in the world.

I believe the better formulation would be to drop the rears by "2psi" from the fronts. Handling and weight distribution will benefit.

so 41/39 is a better way to go than 41 all.
