I have some wheel compatibility questions for my 2008 Range Rover Supercharged (L322 full-size) including if LR4 wheels safely fit...

[TheBucketOfTruth]

I have a 2008 Supercharged model that came with the 20 inch RRC502690MNH wheel. We picked up a set of 19 inch LR4 takeoffs that are from the 2010-2015 era and LR051523 is the current part number (replaces LR013925, LR028929). My 20 inch wheels have an offset of 58mm according to hubcaphaven. On the site it lists the offset of the LR4 rim as 53mm while the 19 inch wheels that come stock on the L322 are both listed as 57mm. Would there be any kind of safety or wear issue when using the LR4 wheels? Aesthetically I prefer the older 19 inch RRC001270MNH that came during the BMW time to the one they came out with for 2006-2009 (RRC502640MNH). Would there be any issue using the older wheel as long as you have the correct wheel nuts for your model year?


The LR4 wheel does physically fit and I have driven on it with Atturo Trail Blade mud terrains, but they are currently off the vehicle. I know there was an odd sound I was getting that went away a bit when I swapped the bigger wheels back on but wanted to check in with the braintrust here to see if they had more info. I was also looking at getting the Compomotive 18 inch wheels but wasn't getting solid confirmation that they would clear the calipers on the Brembo brakes. I know for certain they fit the 2010 and later HSE Range Rovers with the larger rotors, 2006-2009 HSE models, and 2005-2009 Range Rover Sport Supercharged with the Brembo brakes. I believe the Brembo calipers on the 2006-2009 Supercharged that I have are unique to that model. For compomotive fitment inquiries, Johnson Rods said maybe, Compomotive themselves couldn't give me an answer one way or the other, and Vogue Xpeditions said they would fit. Links/photos to the wheels in question I've added below.

The question is what is the width of the L322 19 and 20" wheels and the width of your LR4 wheels, the 4-5mm difference in offste is about the difference between equivalent offsets in a 9.5" and 9" wide wheel.

So the OEM 19 inch wheels for normal L322s from 2003-2009 are 19x8" with an offset of 57mm. The OEM 20s that come standard on the Supercharged models are supposedly 20x8.5" with a 58mm offset. So according to some online calculators that would actually make the LR4 wheel and tire sit 1mm inboard when compared with the 20 inch wheels whereas a standard issue Range Rover 19 inch wheel would sit 5mm inboard from where the 20 inch wheels come out to. So this seemed like a good middle ground to me between those two wheel specs. While I don't want to cause any premature wear on any equipment, wouldn't this just be the equivalent of running a very small spacer on the standard 19s? It seems like the LR4 wheels should be totally fine. Let me know if any of my thinking is off on this as I kind of wrapped my head around all of this this morning.
