Uhm, that link pertains to pressures in _bicycle tires_. Apples n Oranges. I went on tirepressure dot org, a site I use, not the end-all authority, but one that confirms what I stated earlier: in most, not all cases, a higher cold pressure is specified for trim levels of _car_ models with wider, lower profile tires on greater diameter wheels. And my theory still stands: A wider tire patch means more of the tires mass is spread further from center line of tire, increasing something called hysteresis, or delayed flexing of the rubber in response to turning. To reduce this tendency, a higher tire pressure may be employed. This extra 1-2psi over what a narrower tire might be inflated to can also quicken the response of wider tires to driver steering input, something which is not a high priority when I’m out driving. ---

Funny, Chris, asemaster, db and myself are all around mid 50’s, so gen X and are about the youngest of the regular posters, but MOST of the regular posters are all Boomers and or older.. It is a rarity to have a Millennial post on here more than one or two threads… So I am going to say, none of us regular posters are Millennials!!! 😉 ---

The acceptance of the practice of acronyms for everything is largely a gen-Y or Z trait though. That is not meant to be accusatory, only an observation. I am admittedly a kludge and try to avoid acronyms at any cost. ---

And when you push the VSC (vehicle stability control) off button, that pops up on the dash, but so does the AUTO LSD, that doesn’t mean you are given a drug to make you hallucinate, LSD stands for Limited Slip Differential… Just having a little fun… lol ---

I actually feel sorry for the citizens of this decade, imprisoned by this strange language of strings of letters. Someone posted “HBD” on my facebook wall. I asked “excuse me”? They said “it stands for Happy Birthday” I said “If you’re too lazy to type out Happy Birthday than don’t bother” 😂😂😂 ---

Ha in the Tacoma world talk, they will say 2019 TRD OR DCSB 4x4, it took me awhile to figure out OR was not or, it stands for Off Road… lol So you could have a TRD OR 4x4 DCSB, or DCLB, or a TRD OR AC 4x4… DC= double cab, SB=short bed, LB=long bed and AC=access cab, all AC are long beds, so ACLB… 🤪 ---

It’s the way you express yourself: tons of abbreviations and acronyms. As was pointed out earlier, I’m probably younger than at least half of you. But I have an _older mindset_ than you all: I think like the past, I prefer communication styles and automotive and other tech of the past, I AM the frickn past! 🤪🤪 I could never adopt a speaking or writing style like LMK, HTH, YOLOFOMOR2D2C-3PO. My 70 year old church pastor has an Apple watch with his sermons on it. At 55 I still prefer a Bible and a notepad. It’s not natural to me. Heck a lot of things here in these '20s are unnatural to me. I don’t know what happened. Maybe it’s because in my parents car they kept the radio tuned to oldies FM, and at six years of age it wasn’t my business of what they played on the radio. I started to gravitate more toward cultural and behavioral norms from before I was even alive. And they’re all. I. know. ---

I hate to say it, but you probably need to stop using PSI then, and MPH and don’t forget MPG (can’t leave out TPMS that is a fairly new one) then… I am being sarcastic, you know-shooting from the hip, but at what point do we all agree to what abbreviations and acronyms that we use and don’t use, I am sure at some point in history that those were never used, but as the world gets older we learned to adapt to those very common 3 letter thingys, and given enough time, all the abbreviations and acronyms that you complain about will also be common place… ---

Your first 2-3 examples make sense. But when common phrases (as far as I know AFAIK) become acronyms, I’m lost! “HBD” for Happy Birthday is downright lazy and disrespectful. I still spell out most government agencies: Department of Transportation, Federal Bureau of Investigation. It’s about respect and relevance to me. ---

> [@ChrisTheTireWhisperer](#): > > I still spell out most government agencies: Department of Transportation, Federal Bureau of Investigation. It’s about respect and relevance to me. But it is not always about respect, sometimes you are a life long master tech that just flat out can’t spell and not spelling it out is much faster and easier than trying to get a freaking word close enough that spell check or google will understand and correct it, and then sometimes you have to google that word to make sure it is the correct word you want to use, ORRRR you give up after X amount of time and have to totally rewrite the whole stupid thing cause you can’t spell for crap… ---

What a tiny vs. huge bike tire requires as far as pressure is concerned has nothing to do with cars. Your claim that narrow tires require higher pressures than wide tires is contradicted by the manufacturers’ specs, where the pressures can be the same, higher for wider, or lower for wider, but only by a psi or so. Here’s a great example, the Mustang specifies 32 psi regardless of tire, 35, 40, or 50 series: [2015 Ford Mustang Tire Pressure - TirePressure.org](https://tirepressure.org/ford/mustang/2015) [Previous page](https://community.cartalk.com/t/re-wide-vs-narrow-tires-i-rest-my-case/199522.md?page=6) [Next page](https://community.cartalk.com/t/re-wide-vs-narrow-tires-i-rest-my-case/199522.md?page=8)
