Tire pressure?

So yes its still an issue. I was running about 5 psi over the recommeded psi and the dealer told me that was the reason why. The 2nd set of tires I ran at or below the recommeded psi and I didnt have the center wear problem. Also the 2nd set of tires lasted about 20,000 miles longer than the 1st set. Both sets were the same brand. So theres some actual real world examples. None of this "testing" crap.

Perhaps your first set of tires were not steel belted? Many truck tires are not, or are not fully belted. The ones that came on my friend's 2004 Tacoma were not fully steel belted, nor were the ones that came on my coworker's 2008 Tacoma.

Additionally, I would be wary of trusting anything undocumented from a dealership, and only about half of what is actually documented. They are in the business of making money and will say anything to that end. They simply DO NOT want you to get any kind of longevity out of your tires, especially if they offer a tire service.

They were both the same brand of tires and both were steel belted. The rims and tires were an upgrad offered that they get from an independent dist. So the information was not coming from the dealership, it was coming from GST. Im assuming your friend and co-worker's Tacos didnt have 20's did they? No, they probably had 16's or 17's. Got any more excuses?

60 psi ...cool, bet your contact footprint for your tires are about 1/4" x 5"

Yeah, I'd feel reeeeeeeeeal safe with that much of nothing making contact with the road.

On a side note...most tire machines say not to seat the bead of any tire at a pressure exceeding 40 psi...but had an extra 20 psi and get out on the freeway...

Who paid for this testing? Most tire test done are usually paid for by a certain tire company therefore their results they get might not be as accurate as they really are. Money rules all. Also while we are on this note, you have to be careful what you see and here on TV, the net or magazines. For example, I saw some ad on TV last night that said "Men are 4 times more likely to be struck by lightning than women." I bet there are a lot of people that saw that and said "Damn I'm glad I'm a women," or "Damn being a guy is hard." BUT you have to look more into the situation and understand why that is untrue. It should have said "Men get struck by lightning on average 4 times more than women."

i had a set of Bridgestone Winterforce tires put on the Yaris for the winter. I checked the pressure and it's at about 35 psi. The max on the sidewall of the tire said 44 psi. I called the Bridgestone/Firestone tire dealer that installed the tires and asked them why so underinflated. They told me that the best thing to do woudl be to stay within what the car is rated for (whatever it says on the door label)

I think it's a load of crap, cuz I'm losing about 100 kms per tank ever since. Can I inflate to 44psi?

If I was in your boat I'd put them up to 44psi and slowly try going even higher. The only downside to doing this will be a harsher ride, but handling, traction, FE and tire wear will all improve.

You dont think that maybe your mpg went down its WINTER??

You've had bad experiences, but if I was you I'd look deeper into what could have caused your problems, because from my own experience and the experience of plenty of other people over a large number of miles, even going past max sidewall does not cause any problems in the situations like Bailout described.

I don't doubt that you're telling the truth about your own personal experience, but you can't ignore the data gathered by a large membership at CleanMPG for example where no one has had any issues caused from inflating tires to max sidewall or even a little above and the thing is NO ONE paid for this testing. This testing is all done by normal people like you and I and Bailout who have nothing to gain by lying about results. They're only trying to help people be less wasteful of resources and save money with safe practices which are only questioned by the industries which directly benefit from you wasting these same resources.

It's great to have a strong opinion on things, but you can't close the door to so many other peoples experiences or "testing". I'm glad I didn't. I've learned a great deal from Bailout and others like him in the different online communities. To the point where the performance I am getting out of our car is not believed by people who are still pre-believers like I once was.

Well Im happy with getting 44 mpg with no hypermilling techs!

Whatever that means.

I'm always trying to do my best to not waste and cannot understand why someone would brag about underachieving well. I highly doubt you can achieve over 44 mpg on tanks without engaging in common sense, disciplined driving which "others" would label as "hypermiling".

Ummm, yea, please tell me what you do -- I want to do it, too!

I, "hypermile," and I am only getting a paltry 36MPG. Did you rub cheetah blood on your engine block while doing the hokey pokey or soemthing?

[tuckevalastin]

I run 36psi

[BailOut]

I am not sure where all your venom comes from b_hickman11, but it is uncalled for. Your experience, if truthful and accurate, is unique in all that I and thousands of others have learned and experienced at higher pressures.

[b_hickman11]

So its a fluke? Right.....

[BailOut]

Yes, I believe it is either a fluke or a misrepresentation by those that told you it was the fault of the higher pressure in order to escape their own culpability for a substandard product.

[TheRealEnth]

I think it's a load of crap, cuz I'm losing about 100 kms per tank ever since.

Maybe thats why i noticed a difference in mpg when i switched tires? I inflated to the what the car says on door label?

[Snyprwlf47]

Listen center tread wear can easily be tested the same way I use to test my tires for roll on turns. On a dry day take a piece of sidewalk chalk and just make 4 or 5 1inch-2inchthick lines from the sidewall and across the tread. Drive your car for just a mile or less and check to see where the chalk has been worn off. I bet that at 60 PSI you will see substantial center tread wear and at 32 if you have taken a hard turn will find that some chalk has been worn off of the sidewall!!! Easy test that I owe Loren for helping me find to use on autocross

[puetato89]

well i put 100 psi into my 205/40/17's... it hasn't popped yet...(just so you know this was a joke)
