I've seen a lot of cars and SUV's with split pressures on staggered rim sizes, always more in the rear where they are wider. I found wear was uneven (bad shoulder wear) when I followed their recommended pressures on my last daily driver. I raised it a little in the front to be closer to that of rears and that eliminated the tire wear. That was on a different car, and BMW's have different factory alignment settings from other brands, but pressure can make a big difference. Raising pressure will reduce ride quality some, and may increase noise, and there are some other downsides. It's all trade off's.
But no, staggered front/rear pressures is an OEM thing on some models. I don't follow it perfectly, but I watch pressure and wear carefully and make adjustments myself. I target 1 PSI more in the rear, not the 3 that is in the door jamb. Also, I live we don't have hot summers so I'm not worried about over-pressure when warmed up. Most pressure creep I see while driving is 3 PSI. Last edited by chad86tsi; 10-31-2022 at 10:49 PM.. |

Hmm, this is starting to be even more of a debate than the yes/no for anti-seize. I was hoping for a more uniform/objective answer haha.

Asking for recommendations on wheel alignment would elicit similar debate. Do you want best performance, most comfortable ride, reduced tramlining, longest tread life, etc.? Even then, you'll have debate. As for me, I go with the car manufacturer's recommendation until I have a good reason to differ, whether that be from personal experience or reasonable contrary evidence. There's plenty of contrary evidence. Good luck determining what's reasonable. |

You may find pages 2 and 3 of this thread interesting regarding the role of the bolts and surfaces. There are a few other similar discussions on other places on the Internet. https://www.garagejournal.com/forum/....495227/page-2 I’m not saying you are going to destroy your bolts if you lube that surface with anti-seize, but they are not designed to handle bending loads. It’s obvious that the friction of the wheel and hub fit is what transmits the force once clamped and it is important. I am going to guess there is a reason that Porsche explicitly tells you not to lubricate this interface. Probably not a practical issue since the coefficient of friction will still be high enough, but it’s not as ridiculous as it sounds. https://physics.stackexchange.com/qu...-and-its-wheel |

I personally never had issues with removing bolts, and I do 3 cars twice a year (winter and summer).
I do it by hand with a breaker bar. If new tires are being fitted i usually take the wheels to the shop with another car. Reason being is that I like to clean the rotor face, the hub lip, wheel center bore and bolts. Depending on the condition I would hit it with either a plastic, brass or steel wire brush. If bolts have any corrosion on threads, I would run the threads through the drill wire brush. Only place I put antiseize on is the rotor face and hub lip, and I make sure none of it gets onto any threads. I torque the wheels to 100 ft-lbs with a torque wrench. Never trust that a tire shop did the torque right. They hire cheap labor, the job sucks, and the guys working there could give a damn about your torque. Almost all the time when I watch them work, the method of using the torque wrench is wrong. They hit the bolts with the gun and then check with the torque wrench. If its over torqued (which it is in most cases) the torque wrench is not gonna tell you that, but rather click and in their eyes that is confirms the correct torque. |

Since I'm in my winters, I'm not looking to burn up lap times, just want the most safe/effective psi setting(s) for a 225 square set. I'm kinda surprised that there doesn't seem to be any clear consensus. That seems to be my logical assumption as well. The winter tires are all the same size, even though I'm obviously RWD. I found it odd most (all?) shops took the door jamb label as gospel and do the F36 and R42 no matter what, even though it is only talking about a staggered set there...now, whether this is expanded to apply to square sets is the crazy controversy, apparently. I dunno, that's really low from what my manual says (but, unfortunately, it only talks about staggered, so F36 and R42).

Stick in second car with replacement tire. Take to tire change dealer, etc. Get tire changed. Take tire back home, reinstall. This was recently reiterated to MYSELF when I had developed trust with one place. So, I took M5 CS with wheels with 5mm spacer up front, and VERY DISTINCTIVE 5mm longer bolts in the front wheels (the heads are solid and tall). Mr. TireChanger removed all four wheels and (apparently) put all bolts in giant bucket. After changing tires, returned to car, and put whatever bolt he pulled out first in. All 10 extended bolts were distributed about the car, front and back with no regard for where the spacers were. Great. Back to the routine above. Shawn |

Most rotors are now treated with a surface finish to prevent rust. If I use anti-seize on my wheels, it's just a small amount on the lip of the hub-centric ring.

I've had some chuckles reading this over the last 2 days.. but tranquility: Spend the $20-$40 or so to get yourself a nice breaker bar to undo the overtightened lug nuts. Heck, your car should have come with a factory lug wrench even if it doesn't have a spare tire. Put that on and do the balance and bounce up and down until it pops loose (but breaker bar is definitely better and safer). Sounds like your car is in good shape, I know Montreal uses salt and gravel on the road.. but it still shouldn't gunk up your threads. With that being said.. yes never ever use any lube or anti-seize unless you really do need to clean your bolts. It really will throw off the torque etc because almost always people use too much, and it wasn't designed for that anyways. I have had a stubborn lug or two that the plug in electric can't handle. It is also good to note the actual stats may be inch/lb or nm, which isn't ft/lb. Breakaway and torque are also different. I just sprung for an m12 FUEL a few months ago, and boy is that little bugger powerful, I tested it to 140ft/lb on my bench because I was actually going to buy the 1/2" stubby gun after (that puts out even more power). But for now I'm just going to use this. I have TONS of tools including the old school plug in, and sometimes I still use the breaker bar on friends and family's lug nuts. (or other work I'm doing.. it's an invaluable tool).

On my cars, I run higher pressure up front to match or nearly match the rears as I've found this increases tread life, and the tradeoffs are worth it to me. There are trade offs to every decision when it comes to pressures, so that's why you get so many "correct" answers that are also different. |

Is safety measured by :not blowing out tires, or slipping from uneven wear from under inflation, or : not slipping in a corner from stiff sidewalls due to over inflation? Your single criteria is not going to yield a single best answer. We aren't being difficult, it just a complex relationship.
