I noticed that the inside edge of my tires are wearing. This indicates that an alignment is due. I have noticed that most garages and dealers insist on putting 35 psi in the front tires. Ford calls for I think 31 in front and 35 in rear.
What are you all doing out there for correct tire pressue? I am sure tire pressure is also impacting the tire patch area. I have noticed that the front tires are slipping on moist pavement an indication of both the wear and that the tires are not hitting the road correctly. I want to make sure I get this done correctly or am I off base thinking that tire pressure comes into play here.

The tire pressure is noted in your owner's manual. Follow that as your best bet.

I follow tire pressure spec stated on front door label, varies depending on tire size.
Your tire wear does indicate need for front end alignment and probably need for tire rotation.

My door label specifies 31 front and 34 rear. The CD of the shop manual that I got from Todras says 31 all around. My owners manual conspicuously avoids mentioning actual tire pressure at all. Go figure.

Check pressure when cold if possible! 31 psi front 34 psi rear!

Most of time my driving is local, 205-60/15 I usually run 35-36 in frt and 32 rear. I get better more even tire wear this way. And I usally rotate once to twice a year. Depends on the winter and budget, if I can I like use a seperate winter type tire, then it's more than twice. For my 500 mile trips, two passengers and stuffed with goodies for the grandson 33-34 frt. and 34 rear. Did this just 3 weeks ago because of rough ride from the fronts. Good ole freezing and thawing on interstates. Winter tires at 195-65/14 with a Max of 35.
I'm always experimenting, "H" rated tires the good ones that have Max of 44.,only in the front and only for handling and better turn-in. The 89 Probe works better with 42-44 in the frts. but not the 98 Mystique LS. It also depends on the tire and it's construction. Usually the "H" rated and above that have 44lbs. max will hold their contact patch better.
I tried the factory settings? Still don't understand only 31 on a frt wheel drive. Doesn't do much the ride or the outer edges.

Your tire pressure is almost ours changing, for evey 10 degres it drops or raises you lose about 1psi, and you can't just gain it back. I work at Discount tire Co. and I never check my air pressure  but it is somewhat important, but judging buy what you said you need and alignment- a rotation would not hurt you are supposed to rotate every 6-8,000 mils anyway. Hope I helped you out some! -Jeff-

The same thing happened to the first set of Z-rated tires I put on my '98 CSVT immediately after I got it in '99. At about 8000-9000 mi, I noticed the premature inner-shoulder wear, too. But even stepping up the rotation to every 4000 mi, I only got 29K on those puppies.
Turned out that this was due the negative-camber overkill Ford engineered into the front suspension -- presumably to appeal to those who think "performance" is the ability to hard-corner for no particular reason. The CSVT has no camber adjust, BTW.
As soon as I put on new rubber, I took it to a buddy of mine who specializes in underbody work -- basically suspensions and alignments. His shop manager hooked the car up to their Hunter, then used a tool my buddy designed and made himself to precisely bend the strut and eliminate the excess neg camber.
The new tires now have just over 6000 miles on them. Wear pattern is absolutely uniform.
And for anyone in Dallas, I'll put in a plug for my friend's shop:

Jeff, Jeff, Jeff,
Tire pressure is very important! Safety, Performance, Tire-Life, and Gas Mileage are all connected to correct inflation. Dude, don't be so sick of looking at tires that you neglect your own.
Like you, I've always used the 1 PSI rule for every 10-degree up/down temp change. Works very well.
Been a Discount Tire customer for about six years. Good company. My CSVT is now on its second set of Discount Tire's Z-Rated Directionals -- the ones made by Kelly-Springfield. About $530 per set here in Dallas and worth every nickel. But I've learned it's best to rotate them every 4000 miles.

Follow the TIRE MANUFACTURER'S recommendation.
Didn't any of you guys learn anything from Firestone?
The ratings on the door are for the STOCK TIRES ONLY.
When you replace them, you follow the new tires Manufacturer's Recommendation.
