No issues with rubbing with those tire widths?

I have a set of 21x9 and 21x10 wheels on order from Vossen. I was mistakenly under the impression that everyone's been doing +10mm offsets for LCs. I have seen the engineering docs for my rims and agreed not to share the numbers, but I can tell you they are not +10mm. It seems that wheel manufacturers like to protect this data. I can safely share that they've done their homework and that they typically don't let the consumer dictate offsets anyway. So knowing the numbers doesn't really matter much for ordering purposes. I can also share that I placed a yardstick against my fender edges and held it plumb, and calculated the difference from stock 25mm to being flush with the fender edge, and my calculations exactly match what I was told the offsets would be. They are also not the same front & rear. The factory front wheels are tucked in more than the rears, and therefore end up with a smaller offset number to be flush.

Well, IMHO that's just plain silly. I would never buy wheels without knowing the specs. But, that's just me
The factory wheels on an LC are ½" narrower than a GSF or RCF. That's a huge mystery to me. the front tires on an LC are also 10mm less in cross section than an RCF or GSF

this isn't rocket science people, you take the OEM wheel offsets and widths and adjust from there... companies having "proprietary" offsets are just trying to cash-in early on their basic measuring and math skills, and keeping the potential customers who know what numbers they need in the dark.
If you measure how far past the tire it is before contacting the spindles, control arms, and fender liners...you get how far you can go wide towards the inside. Measuring towards the fenders and outside edge of tire towards fender liner at full locks also gives how far out you can go. My guess just at looking at LC suspension is folks can go to a 295 on a much better fit 10.5 wheel with 35mm offset on the front... but I would be happy to run into an LC in Maryland to check in person to be sure.

Almost all wheels have the offset stamped in the back of the hub. OEM 21" wheels are 25mm (both front and rear). That being said, if you wanted to run the stock width wheels, but wanted them to sit an inch wider, you would run 0mm offset.
I took my rear off and put it on the front (to see how a square set-up would fit) and it sat almost perfectly flush*....
Stock front: 216mm width/2 = 108mm - 25mm = 83mm from outer lip to hub face
Stock Rear: 241.3mm width/2 = 120.7mm - 25mm = 95.7mm from outer lip to hub face
So.... to run a stock width front that sits flush, you would want to decrease your offset by about 13mm = 21"x8.5" ET12
*Keep in mind I was looking at the tire sidewall of the stock 275mm rear tire.

Would you happen to have any update on rubbing issues with your 295 fronts and 335 rears? I'm in the process of spec'ing my wheels, and looking to get 9.5 x 21 in the front and 11 x 21 in the rear, so I can fit 255-260 width in front and 305's in the rear. I just wanted to see what your experience was so far on 335's.
Thanks
