Wheel widths and offset?

No issues with rubbing with those tire widths?

Is someone sponsoring you or something? What's with all the stickers?

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

Oh I hear ya. I tried and tried again to get definitive offset numbers before I placed my order. All I got was silence from the manufacturer, and suspicious numbers from forum users. Then I had a candid discussion with the owner of the wheel shop I purchased through. He was happy to share the engineering docs with me (with my understanding that I shouldn't share the details with others), but he also explained that in this competitive business, there are certain engineering details that manufacturers like to protect. This is understandable since from what I saw, the vendor I chose has done an amazing amount of research and I saw surprising detail measurements within their fitment engineering docs. So I could understand why they wouldn't want to give their hard work and research details away to competitors for free. There's no way tires are going to rub on what they produce. I have full confidence in Vossen after learning more about their process and engineering. I can also share this - I called Vossen one day, after my order was submitted, and I got someone that was actually willing to discuss offsets. Although I don't feel at liberty to discuss the numbers, I am fairly confident that they - or your wheel shop - will indeed share the numbers with you once an order is in process. I think they just want to keep those discussions private. Makes sense to me. One other thing I was told - ALL the wheels they've produced for LC vehicles have been made with the same offsets as mine. That includes 22" as well as 21" rims.

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.

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

long time viewer first time poster. I recently purchased new wheels and tires. I went with 21x9.5 et 17 wheels with 275/35/21 tires on the front and 21x11 et 23 with 315/30/21 on the rear. I determined that this set up would work based on my own measurements and using wheel offset calculators online. The fit was excellent. Fender and strut clearance is not an issue. I have not felt or visualized any evidence of rubbing. In fact, when viewing the car from the underside when it was on the car lift, there was still nearly 3/4" more strut clearance with this set up. I regret not getting 21x11.5" on the rear and going 325/30/21 or bigger.
