Wanting to put all-season tires on my X5MC, but apparently none exist in the standard OEM format.

Considering 3 options:

1) Read in another thread that some were considering putting the 295/35/21 tire size on all 4 corners.

2) I can get Pirelli Scorpion Zero A/S in the 295/35/21 for front axle and Pirelli P Zero A/S in the 315/30/22 for rear axle... all have same speed/load/tread ratings

3) Suck it up and just use winter tires


Has anyone tried option 1 or 2, or is that highly discouraged because it might cause issues in the car?

other thoughts?

Is option 1 intended to use the factory 21" wheels (808m), or at least wheels with the same offsets? If so, no problem - it's a factory fit option.

Option 2 will likely be shot down by most. It's never a good idea to mix different tire models front/rear, and Scorpion Zeros and P Zeros are not terribly similar except in name. Would it work for commuter-style (non-performance) driving? Probably. Would the handling be predictable? Maybe not.

I'm leaning towards Option 3 myself. Conventional wisdom would say to put a narrower winter tire on (square 21's, for example). I'm strongly considering using OEM staggered sizes on the factory wheels for winter, and getting a new separate set for summer.

Remember - winter tires are as much about temperature as snow. We had our first cool (upper 40s) weekend of the year this week in Kansas, and the PS4S's on our M2 were clearly down on grip already.

Who knew.... you're right - I couldn't find reference to these anywhere I looked... VERY interested in how you like these.

Just purchased these Arroyo tires from prioritytire.com - thanks Gfit for this great catch

Aren't the Pirelli P Zero All Season another option?

I believe the tires you referenced are the P Zero Summer Tires. I don’t think they make a matching AS in X5M sizes.

The website you show does indicate this, yes, but it is not reality. Pirelli's own website shows the P Zero A/S comes in the rear size 315/30/22, but not the front 295/35/21's

Got it - sorry for the confusion!

I put Continental dws 06+ on ours, did one size taller than oem on stock competition wheels. Ride is better and suits my wife’s needs, it is also lowered with no rubbing. 295/40/21 front and 315/35/22 rear

Is the all season good enough for Chicago winters? Does the extra height make the ride quality softer?

[Black5spdz]

Ride is slightly less harsh. I think so, they are definitely not dedicated snow tires but depending on how much you drive probably they will probably be good. We have other options if the weather is really bad but plan to drive this most of the time. We live in Michigan and get decent snow.

My wife would appreciate a less harsh ride. Michigan is the same as Chicago. Where did the idea for these tires come from? I didn’t know you could install tires with greater height… any safety concerns?

[X5MGuy]

Height of the spare tire might be an issue if you go taller all around. That may or may not mess with the AWD system assuming you try and run it in winter.

[Black5spdz]

Just something I decided to try, I work in the car industry and enjoy modification. Speedo is now dead on at 80. Spare could be an issue if ran for an extended length of time but doubt it would cause any issue to reach a destination. No safety concerns for me at all.

Im starting to lean on getting one larger aspect ratio. It appears the Pirelli Scorpion winters also come in the 295/40ZR21 and 315/35ZR22. I assume the softness of winter plus the thicker tire wall will make it comfortable. But is that too much? Would winter tires already soften the ride a bit? Would it void the drivetrain warranty?
