Me again! My BMW E46 2002 330Ci has always been funky with tire pressure I posted a while back about why it has two different tire pressures listed for the car, one for max weight, and one for 2 people. The consensus was it was because of the Autobahn. Now I found another peculiarity. The manual says to inflate the tires to different pressures than the door jam! And it’s not just 1 psi difference. It’s 29 front 33 back vs 32 front 36 back for two people in the car. My front tires are 225/45ZR17 & backs are 245/40R17. So the triangle and circle on the door jam. I have included pictures. What source do I trust? Also my dad’s 2006 E46 330Ci has the same discrepancy. Thanks! [20240805_114353] [20240805_114247]

[image] ChrisTheTireWhisperer: new Pirellis Junk (mostly) tires… I used to sell them… OEM tires on the Scat Pact Wide Body’s, my buddy said they were junk, also had very poor reviews, then he has ran a few different BS/FS’s and yes some were better others… [image] ChrisTheTireWhisperer: I’m sticking with what I said: I’m sticking with experience dealing with thousands of tires… Never said correct tires don’t matter, but tires WILL/CAN make or break a vehicle… AGAIN, 30+ years experience (17 same company) and REAL LIFE customers telling me about the different tires they had…

You’re calling Pirelli “junk” just to refute me! Then turn around and sell five sets of P7s tomorrow.

Me calling Pirelli mostly junk has nothing to do with you, so don’t flatter yourself… I was selling Pirellis years ago and I was never impressed with them or the P7’s, I upgraded plenty of BMW drivers with plenty of Driveguard’s and Potenza’s and they came back for more… I do not like Continental tires either but I would sell the Extreme Contact DWS in a heartbeat if we didn’t carry that size, I was VERY impressed with them in everyway… Just because I said I do not like tire company X does not mean that they don’t have one or a few that I am ok with or even like, and I said MOSTY junk, meaning most but not all… I am retired now since Sep 2021… So kinda hard to go sell 5 sets of anything… lol, I paid my dues thank you very much… Bottom line I would sell the customer what they wanted, doesn’t mean I would not inform them of a better tire if needed… But I never pushed anything on anyone and would try to talk a customer out of something they really didn’t need… I would also show the customer what the issue was, never hid anything from anyone… I used to hate it when parents would come in and say what is the cheapest tires you have for Jr, it’s his/her 1st car, and I would say why would you want to put the worst tire on the newest driver?? My kids always had the best tire we offered on their cars, I just put Turanza Quiettrack’s on my 23yo daughters 2017 Corolla…

[image] ChrisTheTireWhisperer: WHY are people waiting until service dates to check their own kreldan tires?! We can’t get people to check their own oil in between oil change services, you think they’re going to be interested in tire pressures? I’ve had people complain that the washer fluid needed to be filled between service visits.

We are seriously in deep schitt if that’s the case! I taught myself in my twenties how to monitor things like tires and fluid dipsticks, and probably changed the donut air filter in my 1981 carburetor Buick more often than even my dad would have - 2x per year.

It’s truly a shame that ONE person’s obsession–with one topic–is allowed to dominate this forum.

To quote myself: "As an aside: You wonder why I’m so obsessed with tires, pressures, alignments, etc? Yesterday my wife’s 2004 Corolla came back from maintenance and some new brakes at the same dealership she bought the car from 19 years ago. This morning, I checked her tires? 39-40psi all around! Door placard cold spec = 30psi, front and back. 35 I could understand, just covering their butts. But 40?? No f____ing excuse for such STUPIDITY! Especially if you have ‘ASE’ embroidered into your shop shirts. And I am sure that my wife’s car wasn’t the first nor will be the last one sent out of the bay with tires so overinflated. And if anyone here defends inflating the tires to 45 hot on a car that says 30psi on its door frame, you are just as much an ID__T" If I’m not looking out for, and pointing out such nonsense, then who will?

[image] ChrisTheTireWhisperer: We are seriously in deep schitt if that’s the case! Chris, with all due respect, relax a little. Of all the things to argue about and to call people a-holes about, tire pressures in our cars isn’t one of them. We aren’t in deep anything because of washer fluid levels and tire pressures. There are way more important issues that others need help with like their physical and mental health for example. As much as I love cars, I’m not under any illusion they are that important in life.
