This might be a dumb question but....

MustangV6Man? · December 25th, 2011, 05:09 AM

I have two p225 tires on front, two p235 tires on rear. I have all four currently at about 30 psi. Could or (should?) I put JUST the rear tires at say 35 psi while leaving the front at 30? I have a drop on just the front, not the rear. I figured since it's RWD the back being up a bit would help the car move along better while keeping the front softer for the drop. Or maybe I'm nuts.

i always just run 35 all the way around in both my v6 and in my GT...no need to worry about it being soft...although the rear size is a bit strange...what's the full number for the tire? and do you have pics

Where are you from, MustangV6man? Keep in mind that the air in your tires expands and contracts when the tires get hotter/colder. So if it's 20* where you are right now and you're running 35psi, that psi will increase as it warms up. I know in my area it can be 20* one day and 65* the next.

yep...one psi per every 10 degree in temp change on average

i run mine at about 5 psi lower than what it says on the side wall of the tire...

i'd hope sooo...that isn't the pressure you should run but he tires max psi before it's in range of going boom. in fact most tires i've had say 50psi so 5 less would still be 10 more then reccomended

i have kumho tires (not sure the exact size) and the side wall is i think 45. i run them at about 38 - 40

a bit over pressured for your tire size but not crazy high...

Green_6er · December 25th, 2011, 12:57 PM

i know that they are a medium profile directional tire. what psi should they be run at without sacrificing mpg and tire life?

Skargon · December 25th, 2011, 02:37 PM

If you have the size tire that goes with your car, Look inside your driver side door. It will tell you the Ford Recommended tire inflation for front and rear.

Green_6er · December 25th, 2011, 03:15 PM

alright. i'll worry about that after the spring install (:<
