Square to Staggered?

[kylezer]

Hi,

I have a set of 21's(265/35/21R, 245/35/21F) off a P85D+ and I'd like to put them on my S 75D with a square setup(18'). Will I run into any issues by doing this? Any tire recommendations for this setup? The 21's came with some Pilot Sports(not sure which ones), so would it be best to go with PS4S?

Thanks,

No fitment problems. Rougher ride, faster wear due to softer compound tires, risk of tire and wheel road damage due to lower profile tires. All 21"tires with the proper load rating seem to be about the same

No. Just remember to update the wheel config inside the car so air suspension and range figures aren't freaking out.

I have the exact same setup- there is a slight rubbing on full lock of the front arches. I have standard air suspension if that makes a difference.

Where do you set the wheel config in the car please?

Sorry - just found it in the service menu and was correctly set

The wheel configuration is mainly for ABS and TPMS. ABS & TPMS sensors are in a different location in a larger rim. The car detects that and asks if you changed wheels.

The overall OD of the 245/45/19 and 245/35/21 are almost identical - it doesn't affect the suspension height settings.

True, but I went from 245/45/19 to 245/40/20 and the air suspension was freaking out. It started behaving when I set the wheel config to 21".

That's strange. I am running the same tire size and I have my wheel size set to 19".

The air suspension doesn't actually know what size wheels you are running as they just hang off the suspension.

I'm actually running lowering links so that may have something to do with it. It was dropping lots of air ans then filling it up every minute even while driving.

Sounds like you either have a leak in your air suspension or a bad sensor or both.

Nothing wrong with my air suspension, no leaks. Like I said earlier, the issue was fixed right away when I set it to 21".
