mikenmar Report post Posted May 19, 2010 (edited) What tire pressure are you all using? I think the manual says 32-33 psi, but wouldn't you use a bit more if you were willing to sacrifice a little comfort for the extra mileage?

2010 Sport Blue SEL Report post Posted May 19, 2010 What tire pressure are you all using? I think the manual says 32-33 psi, but wouldn't you use a bit more if you were willing to sacrifice a little comfort for the extra mileage?You've opened a can of worms here. My guess is there are going to be dozens of different opinions on this subject. Personally, I inflate to 33 psi, as stated on the door panel and in the owner's guide. I keep pretty close watch and check frequently. I have a thermometer in my garage and a small compressor, when the ambient temp changes I check and fill or deflate as needed. I use the average daily high temp as a guide and always check when the tires are cold. Here in Minnesota, one needs to keep a close watch winter to spring and fall to winter.

xmech2k Report post Posted May 19, 2010 I think long term, running such a high pressure, you'll get uneven premature tire wear. Will it be worth it when it comes time (early?) to replace them? Quote Share this post Link to post Share on other sites
rfruth Report post Posted May 19, 2010 I think long term, running such a high pressure, you'll get uneven premature tire wear. Will it be worth it when it comes time (early?) to replace them? Is my ~37 the high pressure x (the last few cars I drove I ran a few more PSI than recommended & had no uneven or premature wear but will my Fusion be the same) ?

Rodeo Report post Posted May 19, 2010 I am running 35-36 psi in my Milan and that's a few pouinds above the recommended 33 on the door sil. I ran the same tire pressure on my Ford Escape in Continental tires and they wore like iron, getting over 60K on them before I replaced them (just becuase I could, not because they need to be.) They still had lots of legal thread left and the wear was even. I think a few pounds over prolongs tire life, not hinders it. Quote Share this post Link to post Share on other sites
oldschool1962 Report post Posted May 19, 2010 (edited) It's always been my understanding that........if you run just under the max pressure as stated on the tire you shouldn't have issues with abnormal wear or safety concerns. Just remember not to exceed the maximum pressure and take into consideration the 1-3lb increase in pressure as the tires heat up. To get a good gauge of this you should check pressure after you have driven for a while. You can always reduce to set it under that max stated pressure if it exceeds it. We have typically run the higher side of the scale with no issues...... at least what I can recall over the last 40 years.

Just remember not to exceed the maximum pressure and take into consideration the 1-3lb increase in pressure as the tires heat up. To get a good gauge of this you should check pressure after you have driven for a while. You can always reduce, as needed, to stay under the max stated pressure. We have typically run the higher side of the scale with no issues...... that I can recall over the last 40 years.Tires don't state "running pressure" they state the "maximum pressure" and are rated for their speed rating, knowing they will heat up and increase in pressure as you drive. The maximum pressure is not the recommended running pressure and that info is typically specified by the car manufacturer and in the case of Ford, put right on the door sill in plain view. The recommended pressure assumes the tires will heat up and increase on their own, so no need to compensate and deflate for heated expansion pressure. it is this fluctuation in pressure that causes more wear then had the tires remained constant and that's one reason why inflating with Nitrogen is so beneficial. Nitrogen filled tires will reduce heat and keep pressure constant, prolonging tire wear and lessening chances of blow outs too. Not to mention an inprovement in fuel mileage as well. Tires should never be adjusted hot or warm even. Edited May 19, 2010 by Rodeo Quote Share this post Link to post Share on other sites
rpreuss Report post Posted May 19, 2010 Interesting discussion. Everyone (as expected) is saying "follow the door sticker", "+ X lbs.", etc. Try this the next time you are with a bunch of your "car" friends... Everyone get out your tire gauges and all measure the pressure in the same tire. (NOTE - Do not do this AFTER you have your beers... you may loose too much air between each reading). Now compare the readings. I will bet that you will find quite a range of readings, +/- a couple of PSI. For the most part, these are all cheap gauges with quite a bit of variations. So, keep that in mind when you are adjusting your tires to your own "preferred" pressure. Now, go have your beers. :beerchug: Quote Share this post Link to post Share on other sites
