Apparently Goodyearman agrees with Michelinman

How much air should I put in my tires?

Proper inflation is the single most important part of tire care. The inflation pressure on the side of the tire is the MAXIMUM operating pressure. It is not necessarily the right inflation for your vehicle. Always use the inflation recommended by the vehicle manufacturer. You can find it in your owner's manual, posted on the edge of the driver's door, on a door post or on the inside of the glovebox door. Always check inflation when tires are COLD: when the vehicle has been driven less than a mile or one hour or more after driving. Use a good quality tire gauge. Note: It's natural for radial tires to have a slight bulge in the sidewall at their proper inflation pressure. Check or adjust inflation every few weeks, before any long trip or if traveling with a heavy load. And don't forget to check the spare. Your Goodyear retailer can answer any questions you may have about tire inflation.


Bridgestoneman also agrees

Dunlopman too, with a decent description of why over inflation is bad

But I agree, anecdotal evidence >>>>>> decades of research and experience.

LOL! :laugh:

So wait...you'd rather listen to random observations instead of scientific facts? :confused:

I seriously hope you're just trolling...

You were one of those kids that couldn't just take "Because" as an answer could you.

This is truth.

You're still a kid. When do you graduate HS? Do you even have a driver's license?

You may do 32 - 42 PSI.. sure not much of a prob, but IIRC the OP is talking about running 80+ PSI.

See, most rational people look for articles, studies, or scientific proof of something rather than anecdotal evidence...but not fleabag. Facts aren't good enough for him, he seeks out vague and often uninformed opinions to base his logic on. :laugh:

You can't make up stuff like this. :laugh::laugh::laugh:

Anecdotal Evidence:

When the facts simply aren't good enough, seek out the random observations of random people who happen to agree with your zany ideas.

side wall doesn't account for vehicle weight. over inflation causes tire to bulge on the tread which lowers contact area and traction. moron op trying to get people killed.

Or fail to do so:)

1)I have seen center wear patterns on overinflated radial tires, and edge wear patterns on underinflated radial tires. The OP's surmise about wear patterns and radial tires does not reflect my personal experiences.
2)My personal experiences on ice and snow have been overwhelmingly better at or below the automaker's recommendations, and well below the sidewall number.
3)tire pressure is another tool in my toolbox of tuning; more than once I have extracted a stuck vehicle by removing air from the tires.
4) my experience with tire temperature/overheating? get out and feel the tire sidewall, check the bearing hubs and rotor/drum for bad bearings/dragging brakes while you are at it. If it is only warm to the touch, you are good to go. I've lost tires due to overloading in dual tire installations, due to a flat or tire failure in an adjacent tire. Now I check them for temps as well as pressures.

My experience:
A farm hand in the 70's. Tractor tires need love too!
Worked at tire store and service station in the late 70's, selling many radial and bias ply tires, snow tires, studs, chains, split rim tires. I can still work a coats machine or balancer if needed.
I have driven commercial trucks since 1980
I can easily tally up 700,000 miles in cars alone, and probably 100,000 in truck logbooks.

Intentionally over-inflating your tires with the knowledge that it decreases traction (and thus safety in some situations) is pretty fucking stupid and selfish.

You're not overinflating if your at max or less. The car manufacturers specify a lower than max inflation for the softer ride, that's it. I've put more miles on the road than probably everybody in this thread. From cruising at 90mph, to driving on cobbles in the city, to creating trails through the woods, and I've had 0 problems with my traction....

And how many miles would that be?

Easily over 1,000,000

For quite a few years I was driving over 50,000 miles per year. I haven't been lately, but I've driven a ton on everything from a VW bug to 1 ton pickups and vans(currently a Jeep Cherokee)


Good start with your mileage. I quit counting when I passed 1M miles a long time ago duing the late 1980's. I've slowed down lately as I've gotten older, but still average between 26K-35K each year....and probably passed 2M well before today.

And as for vehicles, I've owned over 50 so far in my life, including 3 VW Bugs, a 1969 442 W-30 Olds convert, a '69 Olds Cutlass convert, 2 1966 Plymouth Belvedere II's, a 1964 Plymouth Savoy, a 1974 Fiat X 1/9, a 1969 MGB, 1968 Rambler American, several station wagons during the 1970's-1980's including Ford LTDs and Chevy Impalas, several Chevy/GMC 1/2 ton pickups during the mid-1970's-1980's, 1974 Honda Civic, 1972 Chevy Nova and a 1966 Chevy Nova II, 1970 Mustang, 1975 Mustang II, 1968 Honda 350, 1974 BMW R75/5, 2002 Honda Nighthawk 750, 1995 Chevy Silverado, 1994 Ford Ranger, 1990 Plymouth Acclaim LX, 1991 Dodge Spirit ES, 1994 GMC Safari, 1996 Mitsubishi Galant, 1995 VW Golf, 1985 Chrysler LeBaron turbo convert, 1990 Pontiac Grand Am, 1986 Chevy Cavalier, 1974 Chevy Vega, 1976 Chevy Vega, 1973 Ford Pinto, 1977 Datsun B210, 1980 Nissan 280ZX, 1972 Plymouth Satellite, 1985 Pontiac Fiero, 1990 Chevy Blazer, 2002 Chevy Blazer, 1982 Ford Escort, 1986 Toyota Corolla, and a lot of others....but this is just off the top of my head. Most were "secondary" vehicles, some were primary vehicles....

Of course, for a decade centering on the mid-1970's through the mid-1980's, 50K per year would have been a nice decrease in mileage for me as I was driving the dog show circuit in the U.S. Crisscrossing the U.S. repeatedly during the year really adds up the mileage.

Then during the late '80's, I did extensive driving buying/selling/transporting exotic endangered birds....such as Sumatran and Indonesian pheasants. (Yes, I'm licensed to import/export buy/sell breed/raise endangered species, esp. birds.)

We've cut way back in driving, but still put 12K or more simply driving around to auctions or cruising to Atlanta. This in addition to the puttering around the house going shopping and going to work.

So impressive as you may try to sound with your "experience", remember when you start trying to flaunt things like that, there will always be someone with more, and sometimes you will get embarrassed by pounding your chest, crowing about how experienced or better you are than someone else, because there's always someone out there with more or better whatever than you can ever say you've done.

Oh, and on topic, I've tried overinflating beyond the door placard, esp. to increase gas mileage. And while that does work, it sure does wear out a set of tires faster in the center and does negatively impact handling. Been there, done that, gone back to going over the recommended pressures by only a few psi now. I will sacrifice a little ride for a little better mileage, but I do keep a close eye on tread wear with a tread gauge because hyperinflation of tires does cause premature wear in the center of the tire.

Yep, but since it's a tech forum with an automotive subforum, we obviously have no idea what we're talking about.

So apparently OT is better.

To what pressure should one inflate a Buddha anyway?

ZV

Just give him a few thrusts and shoot off whatever you want to into Buddha.

just dont exceed the maximum or you could have a blow out.

Maybe this should get moved to Highly Technical so that the incredibly intelligent folks over there can confirm that the OP is correct....orrrrrrrr not.
