My 827m’s (m3 cs) wheels came in and I’m running 20x10.5” squared on all four corners. I’m going to reuse the stock pirelli pzero tires as they have less than 400 miles on them and are the exact same size I’ll be running on all four corners (285/30/20).

I purchased a new pair of star bmw Michelin PS4’s (to replace the oem fronts that are 275/35/19), because well I like them more and they were on sale at the same price as the pirelli’s. Question, would you run the Michelins front or rear? I’m not bothered by the different makes. I know some people would be.

Seems weird to spend all this money on a car and wheels then run mismatched tyres, especially with xDrive.

Thank you so much for your concern although that wasn’t a question I had. The diameter of the tires is 0.13% difference, which is closer than the oem staggered arrangement at 0.4%. Therefore your concern regarding xdrive is flat (pun intended). FWIW different tire models and even brands are run all the time in motorsports because the duties/loads on the front and rear of a car are different for example steering, braking, and weight biases. Now if you don’t like it because they don’t match (manufacturers) then fine. I get that.

Any other concerns? Oh, as I stated before I prefer MPS4S, but I’m not hocking brand new pirellis unless I must.

Do a matched set. Pick a brand. Both are very good.

Are you purposely trying to make this non matched set bother me aesthetically speaking? It’s working.

I would do it strictly so the tires all behave the same. I wouldnt want the rears with a different grip profile than fronts.

I appreciate it, but neither brand/model are front or rear specific tires. 🤷‍♂️

If you’re cornering and the Pirelli’s have less grip than the Michelins your rear is gonna slide out. Pick a matched set.

Ok, Do you find pirelli’s have less grip than Michelins. I’ve never run pirelli’s tbh.

I kind of agree with TopJimmy
He is saying that different tire sets behave differently under same conditions. I think he is right. So u may end up in a situation where front and rear behave differently. Doesn’t seem to make a lot of sense to do that.
I don’t think you are going to get consensus here on what u trying to do. It’s just very unusual way to do it. Not criticizing it but just don’t see the reason.

I can see how tires are designed to work as a set. That’s more or less what I was looking for, an analytical (performance) perspective rather than someone just saying do a matched set as a fashion cop. Thanks brother 🙏

[E63M6_G42M240i]

Thanks for the advice guys. Full set of MPS4S on their way.

Yes. Especially if you get the Michelin star oem tire. Good call with the full PS4S star setup. Enjoy

The main thing Pirellis have going for them is they have a stiffer sidewall and feel more precise, but in all other regards PS4S beats them in my experience. Good choice.

Don't mismatch. Dangerous to combine different tires, and Pirelli's are a bit larger and will rub where the Michelins will not. Just keep them the same, trust me.

Thx I’ve ordered all Michelins star MPS4S

I have a 2022 6MT M4 and I just replaced my 2-year old Pirelli PZero's with the Michelin PS4S*.... and I must say they seem to have better traction, especially when shifting at high rev from 1st to 2nd gear. On the Pirelli's, from day 1, the wheels would spin once you landed in 2nd gear. With the PS4S*, I am not having that issue, the wheels seem to be able to handle the power and grip/propel you forward. It is a noticeable difference and something I was not expecting.

I am in Los Angeles, so mostly dry roads 98.9% of the year.. but worth mentioning the other difference was in the rain, which I must say the Pirelli's felt more grounded/confident, but not by much.

Bottom line, if you are like me and had (5) BMW's and always wondered if the Michelin PS4S* and the Pirelli PZero's were equal, they are not. They are very close, but I have to admit the PS4S*'s are just overall better.

Are you talking about the PIRELLI P ZERO (PZ4) Star BMW, or non-Star/ standard version? It would be interesting if there was that much of a different between OEM Star BMW tires from the different brands, considering BMW “works” with these companies for a Star spec that meets BMW’s performance criteria. E.g. the PS4S Star BMW is really a hybrid Sport Cup 2 compound.

PS4s are more comfortable and have better traction than Pz4s. Pz4s have better turn in response though

Sorry didn't see this. Yes I was talking about the Pirelli PZero Star BMW OEM tires that my car came with. And yeah I found it interesting too, I assumed there would be no real discernible difference between "BMW Star" tires, but there appears to be. Shocking to me..but obviously not to others as I always heard about 'winning the tire lottery' when people post about getting PS4S's on a new car. In the past I always dismissed the remark but clearly there is a difference, even if it is just a slight difference.

The PS4S Star BMW have better traction, and seem stickier than the PZero's. Also would agree that the PZero's have a slightly better turn in response but otherwise the PS4S's seem overall the better tire.
