What is highest PSI in tires you have used?
Just curious. I recently increased my tire psi to 50. Made a huge difference on mileage.Has anyone ever gone over 60 psi?

prob not a good idea. I don't think your supposed to go over 44psi and when tires get hot the pressure goes up sooooo

Increased to 50, from what?? I've been running 44 psi since I got mine, so can't really attest to the gain, though I'm sure it's there. Once in my shop, I can push it around with one finger pretty much, light and low rolling resistance works every time, low tech but effective! I run ALL my equipment at the max psi, as stated on the sidewall (tractor, 22 ton boom truck/crane, and pickup.)

That's very scary if you really do push it like that. We had to watch videos during training at the tire shop I worked for, they showed a tire inflated until it burst, it flew about three stories in the air. Of course that tire/rim was off the car,but it was locked into the tire mounting/dismounting machine. They have a special 6" steel tube cage lag bolted to the concrete for tires that won't seat on the bead... to keep people faces from getting taken off. A tire popping at normal PSI can be dangerous, fill it until it bursts and it's a whole new ballgame. http://articles.latimes.com/1991-08-..._16-inch-tires Quote:

I run max sidewall also, which means 44psi in the all seasons, and 55psi in the snows. (2 different tire brands) Of all the things I have tried, tire pressure and practice have made the biggest MPG gains.

just keep it under the sidewall max!! this is generally 44 psi on most all-seasons, but can vary some. I have personally seem the outcome of overinflated tires. Fuel economy (blasphemy time...) is less important than safety. seriously.

Though I believe running my tires at 44 psi is no big deal, I do agree that at some point it can get spooky, at least the big truck tires. I have a part time employee who's father got hit by a split rim at a truck tire shop, put him in a coma for 25 years, THEN he died.

I normally run mine at 60 psi all year but I've had as much as 65 in them.
65 is not even remotely approaching the pressure it would take to cause a rupture. I don't find the ride at 60 to be appreciably worse than at 44 and the car handles like its on rails. Someone posted a law enforcement article recently about upping pressures for performance. Showed a Ford Ranger on 2 wheels with 100 psi in the tires. Bet that rode stiff-especially when they set her down! R2 |

I see this as an economic issue not a safety issue. If I can get more mileage and save money at the pump, the cost of new tires will only be more if they offset the fuel costs I don't have to buy. And since I already have 50k miles on my OEM tires and probably will get another 20k more, I am riding on free tires and if I can save even more on gas by increased tire pressure, its not dumb. Its money smart.

The money you save over the life of your 100 dollar tires might just cover your deductible, but will it cover the potential lives lost? Now, at 50lbs I really doubt you'll have an issue...but that's where it starts, it ends upside-down on the freeway after you've gotten complacent with Your "experiments" and normally I'd say it's your life, do with it as you please...but when it comes to driving you have to consider the lives of the people around you, that's what's really at stake here. It's not money smart, it's selfish. http://www.popularmechanics.com/cars/news/4199963 Quote:

I have tried 40-50 psi in stock and aftermarket V rated tires. Grip and mileage were slighty better (1-2 mpg) but I am down to 36 psi now, the car just rode too godamn hard. Joints in the interstate were torture, and road noise was up too. I just made a 800 mile round trip at an average of 70 mpg at 37 mpg overall. Thats good enough for me, I think I'm ready for new shocks at 75K miles now, I'm tired of being beaten to death.

You need to climb down off that high horse. Most of the people on here seem to not have any safety impacts and the savings appear to be very common sense. You are more than entitled to your opinion, just as we are entitled to ours. But it isn't selfish....but maybe you don't really understand the meaning of the word.
