Hi All

 

I have my tires set at 45 PSI.  Door sticker says recommended 40 PSI.  I would think that this recommendation is for ride comfort as well as road contact (traction for acceleration and braking) as well as proper wear over time.  

 

I am thinking of increasing them to 50 PSI but I am concerned about all of the above.  Has anyone running higher pressures worn out a set of tires yet?  What are people seeing with regard to wear?

 

Thx

On most of my previous cars, I have normally kept my tires at higher than "door sticker" recommended pressures, and my tread has always lasted longer than rated.

I run 55 psi. Great wear and traction. I only have 2K miles, but they look perfect.

Only 55? I run 300 in mine. OK, it's 300 kPa  ;)

Interesting
I will check my tire pressure. It is getting colder and betting they are low.
Thanks for the tip

I've been getting good numbers with just running the factory specs. I guess I could do a little better by pumping up the pressure, but I don't want any issues, should I have any incidents involving the tires.

Odd. My door sticker says 38. I run mine at 44.

 

But I do have an Energi, although I can't imagine they would be that different!

I was wondering the same thing.  I thought maybe they changed the recommended PSI in 2014 but I see yours is a 2014 too.  Not sure why?  I would think the Energy might be higher due to the extra weight but this is the opposite.

They did up the tire pressure in the 2014 by 2 PSI, I believe. I think that it went from 36 to 38, but I can't remember.

Wow- so glad I checked my tire pressure.
I was driving home and low pressure warning popped on.
I was only one mile from home, so drove home and allowed the tires to cool.
I checked the pressure and was down to 30. I hand pumped with a bicycle pump(yes it can be done but takes a lot of pumps -about 10-15 per pound). I rechecked the pressure with my gauge and was a perfect 40.
With the weather warming up, I went with factory specifications of 40 psi.
This really improved my mileage.
Thanks!

How does one find out if factory specs have changed??? Trying to find any info has proven difficult.

 

Like my last oil change, they have upgraded the 2014 to 0w-20.... it took me several attempts to find out this was true. 

 

A month later I checked my PSI and it was 45, door says 40...... Have the specs changed that much???? 

 

They told me they had set everything to spec....

 

Or do I need to find a new ford dealership to do maintenance????

The OK for 0W20 has been discussed on this foum quite a lot.

 

Right after the 0W20 was appproved for the C-Max new new models, many of us posted that we inferred that this would be ok for the 2013's as well.  Immediately there were many adamant opposing views posted, including some from the Ford reps to this site.  Eventally, Ford came around and retroactively approved the 0W20 for all C-Max models - but it took QUITE a WHILE !!

 

Similarly, there has been a large body of opinion posted here that would indicate that 45 psi tire pressure or even higher would be notomly ok but actually preferable.  Again there have many adamant opposing views posted.

 

I have not, however, seen any notice of 45 psi getting the ok from Ford.  Has that happened yet?

I've got a 2013, and the door panel says 38 psi for the tires.  I had to take it in to have a small leak fixed in one of the tires, and asked them at the dealership to check all the tires and inflate them to the proper pressure.  This morning I checked and they were all 42!  Either the dealer is following new recommendations that came out since the 2013 models, or they've got bad tire pressure gauges.

 

Anyone have experience with the dealer increasing the tire pressure?  They didn't say anything to me about this.  I'll try to call them tomorrow.

 

Thanks.

I've been happy at 40.  every now an again I get a low pressure waring  never the same tire.  but this time of year with the wild temp swings  not uncommon to have pressure changes in the tires

 

IMO  40 is a nice setting for comfort/mpg.  any higher and it feels like I'm getting rabbit punched over ever bridge and concrete joint  and since we are finishing up the winter season  potholes are blooming faster than pimples on prom night....  definitely don't need a cut tire or bent rim...

Dealer always sets mine to 38 psi.  So, when I get home I reset to around 47 psi.  IMO, if you feel the ride is okay (e.g., not too jarring when going over bumps, potholes in the road), I'd leave them at 42 psi.   I've never experienced uneven tire wear by going significantly above the manufacturer's recommended pressure.  I always get outer wear at the manufacturer's recommended pressure - based on 40+ years of driving. :)  

 

If you want to continually monitor tire pressure and have a smartphone, you might want to look at the ForScan App - around $30 for the App and ELM 327 adapter to plug into the OBDII port.

I have 65k mi. on my second set of Michelin's running 50 psi and all tires have even tire wear between 3 and 4/32. Interesting that one tire is a hair under 3/32, one is 4/32 and other two are between.  Time to get a new set of Michelin's. :)

Got a New Set of Michelin's yesterday, What a Noticeable difference. As I expected they would be quieter, but the ride was softer too. The FORD Dealer put 42lbs in the tires and I could feel the car wasn't rolling as easy as before so I  raised the tire pressure to 50lbs.  I could tell a little difference in rolling resistance and slight difference in ride. :shift:

Did 14mi. trip with bike on the back last night and got 56.7mpg with speeds 35-55mph so I haven't lost to much from putting the new tires on. :)
