Hey guys. Installing the All Seasons Michelin this friday with the 265/40 and 295/35. I have always ran the PSI true to what the door sticker says and on cold and I never had issues. My summer and also winter tires seem to be wearing evenly. Questions: 1. What PSI do you run with these sizes? 2. Do I need to redo an alignment since I am going to be running different sizes?

I've been running it at the recommended pressures still as I see over 100 once in a while.

No need for realignment unless you are messing with suspension.

Swapped by Snow Tires and got my Michelin PS All Season installed today.(265/40/21 & 295/35/21) They look amazing. I did the Tire Pressure PSI per sticker of 33 front and 38 back but screen is saying I have low tire pressure. I did change in the screen to the Summer tire with 265/40/21 Setting. I had it in Winter Tire setting before. Do I need to change it to the Race setting?

Bought the Michelin PS4 SUV 265/40 + 295/35 R21. And now I feel "kicks" after release gas pedal near 1000-1100rpm If I switch the car from 4WD to 2WD mode - car drives very smooth without any issues.

Stock size 255/40 + 265/40 means that rear tire 1% longer, but current setup means that rear tire 1% shorter, so we have 2% difference compared to stock ones.

Jerks, kicks. It does not slow down smooth as in 2wd mode. Like someone kick your ass and then slow down.

I am currently running Pirelli winter tires on it. I really like when I have switched to winter tires because the ride overall feels smoother and softer. We know we have a rough ride with our X3M. Its a night and day when I put the Conti's on. I was thinking on switching to Michelin for summer and my questions are: 1. All season PS4 or Summer PS4S? I am not running track with my vehicle but do get to speeds of 100mph on the freeway from time to time. 2. Which set up is the one that will match the side walls? It will drive me crazy to see them different. haha. 3. I am thinking of doing the 265/40 and 295/35.
My main concern is to have a softer ride. I assume for city driving that both All Season and Summer will give me the performance needed. Thank you
I'm going to offer a different opinion than most of what I've read here in regards to the ride quality of these tires. I have the PS4S in sizes 265/40/21 Front and 295/35/21 rear on my 21" forged summer wheels. I replaced the stock PS4S (I won the tire lottery when I picked up my 2020 X3M) with PS All Season 4s on the stock 21" rims for my "winter" setup in the factory sizes: 255/40/21 front and 265/40/21 Rear. So I think I have a good opinion after 3 years of running both the PS4S and PS AS4s. From my experience, even at similar tire pressures, the summer PS4S offer a noticeably "softer" ride than the All Season 4s. I'm not sure if it is due to the harder rubber compound on the AS4s or that they have a stiffer sidewall, but there is no doubt in my case that the summer rubber offers a smoother overall ride. Plus the larger summer rubber just makes the car feel so much more stable under acceleration and braking. I feel less confident on the All Seasons.

Even when I switched my stock wheels from the PS4S in the stock sizes to the AS4s in the exact same sizes (and running same tire pressures), I remember noticing that the ride quality decreased by a noticeable amount.

Since you have winter rubber already, I'd say go with the true summer rubber PS4S. If you want the nice "Premium Touch" velvety sidewall graphics, you need to go with the 255/40/21 front tire and then the 295/35/21 rear. The 265/40/21 has the older sidewall graphics (at least last I checked) so they don't match perfectly. Plus, the 255/40/21 is an even closer diameter match than the 265/40/21 front, so even less chance of developing transfer case issues down the road. The 265/40/21 is still within the 1% diameter difference so it should be safe too, but the different look of the sidewall does bother me at times.

Hope this helps

Edit: Crap, I see that you already bought and installed the All Seasons. Well, they are still really good tires

I coded 2WD mode like F90 has from factory. Now I can select 2WD in menu and car becomes rear wheel drive. So all torque goes to rear wheels and car drives really smooth.

Well due to my car being rear ended I get numerous malfunctions and one of them puts me in 2WD mode. I can remove the traction control and get squirrely with it now lol My car goes into the shop soon for it to be fixed.

UPDATE:
1. I have jerk/kick after the gas pedal release only on 1st gear near 1000-1100rpm
2. Today I changed a wheels to same sized 245/40 + 245/40 (just for test) = no issues.

Switched!

I just happened to still have my Macan's old 21" Pirelli tire set (265/295) so I switched out my stock tires with them. The fronts fit nicely, but I feel like there is a lot of extra lip (where the tire meets the rim) on the rear. At least compared to when they were on my Macan's rims and the old 265s. I would think they would be tighter (if that makes sense) since it was a wider tire than stock. The ride is nicer. Not as harsh. Also, I have a set stock tires for sale for those interested! Additionally, does everyone's exhaust sit a little crooked like mine? Or am I being paranoid? I know there is always some flex, but it seems like a lot to me.

Unrelated question, why does everyone “block out” their license plate on photos? What’s the concern? It’s in full public view when outside right?

I thought I was ocd…my exhaust also sits like that on the drivers side.

Oh and I call that “extra lip” buldge. I’d rather see buldge than the stock tire stretch. I think the stretch looks a little ricer-esque. Like your going for a stanced look.

Has anyone noticed a MPG drop running the larger tires? MPG is important to my wife and I at the end of the day.

When I bumped my truck up 1 size my mpg dropped from 17 to 13 and Im still rocking a nearly factory sized tire haha

I haven't noticed a big change & drastically reduced numbers in overall MPGs. But then again I made this nice tire upgrade pretty early on & more rubber equals more rolling resistance. Confident that if properly inflated & consistently checked, the change should be relatively minimal. Just my .02 cents.
