After reading some old posts, I decided to start one of my own to get some advice for my specific situation. I own a 2014 P85D with the plus (air) suspension. I also installed the unplugged lowering kit a few months back. My current wheels are the staggered 21" turbine wheel setup. I'm thinking about upgrading to 22" wheels. I've seen a few posts with tire/wheel sizes people here are running. Is there a "definitive" size tire/wheel I should get? Will I need to match the 21" diameter closely, or did the update that allowed you to change your wheel size through the MCU change that requirement at all? Has anyone run 22" wheels on the plus suspension? I assume it's not a big deal, just checking before I invest the money into the new setup. Any advice from someone that has had this setup for some time would also be appreciated. I realize there is a majority of people that will say not to get wheels like this for a myriad of reasons. Im aware of the inherent risks and downsides. I'm willing to deal with all of those.
Front: 22x9 Wheel, 245/30/22 Tire. Rear: 22x10.5 Wheel, 285/30/22 Tire The outer diameter of that setup matches OEM close enough, and doesn't cause any issues with the ECU. I had 22's on my P90D with Air Suspension for a couple years, it looks great. Just remember that those tires are quite thin, and will be prone to bending your wheels (like I did mine). I eventually switched to 21's of the same width to give myself a little less to worry about when daily driving. But that's just me, don't let it sway you - they fit, they work, and if you like it, go for it.
Thank you for the reply. That setup looks great! Mine is daily driver (for the most part, have a second car I can use) so the curbing a wheel is something that would be a concern for me. Was yours lowered at all? Wonder if anyone has heard of a way to fool the ECU into accepting a bigger tire.
I think the plus suspension will make you even more vulnerable to wheel damage. The plus suspension is great and very responsive, but it is stiffer than the standard air suspension. The plus suspension will absorb less energy in the bumps, and the wheels and chassis will end up taking more of it.
Mine was lowered with Unplugged Brackets. You don't need to fool the ECU into accepting a bigger tire, it doesn't care. I had 255/30/22 and 285/30/22 on my car at one point, and from an ECU standpoint it was just fine....but it rubbed like crazy all the time.
