It’s a rule of thumb that I saw posted here or benzworld.com. They came to that conclusion because that is the largest difference in Front/Rear OD on a 4matic that MB has rolled off the production line. It is probably safe to go with a larger %, as others have done but I didn’t want to go beyond what MB has done before.
Like I said before, many as do I believe that it’s a myth but I prefer to be safe than sorry and stuck with the .02%.

If you want to be sure research the wheels that MB has put on its 4matics throughout history.

I have been a member of forms for every vehicle I've owned in the last 7 years, HOWEVER, when I no longer own those vehicles, I stopped going to those forums! I guess he has nothing better to do or has lots of free time to kill, discouraging new members on this forum. What ever makes you happy.

Thanks! I fully agree. I intend to look into this as the warmer weather approaches. It should be added that staggering your wheels/tire combo could mean several things, but the one I'm after, (as well as the OP I believe) is to increase just the rear wheel/tire width but maintaining the same roll circumference as the front set up (+- that .02% difference) as well as the correct offset... (or as close to it as possible.)

Thanks again.

This thing looks fantastic IMHO!

So when you take the staggered approach I would assume that you are buying new tires. If you do that most manufacturers insist on tire rotation. Do you give up your rights to a tire warranty?

Yea as with most things in life you have to $acrifice $omething for Vanity. Staggered setup has some performance benefit but you will change tires more often because you gave up your right to tire rotation.

Well after much debate I've found a set of 22s that I am interested in, but the seller could not guarantee fitment for me...so I come to the board to ask your advice. The wheels are 22x10...offset 50...hub bore 66.6..bolt pattern 5x112. Is anyone currently running wheels on their GLK with these specifications? Or does anyone know if these wheels will fit the GLK?? If so, what tire size would you recommend? Thanks as always!

You'll be fine, brake calipers won't present a problem and the hub size and bolt pattern are correct. I'm not running 22"s, just aftermarket 20"s and just went through the same thing. I'd use TireRack.com for fitment size on your tires. Let me know if you need some centering rings, I'll send'm to you for postage.

Thanks alot Emdem! I appreciate the input. As long as you're sure the 22x10 will work, I'll give TireRack a call this afternoon to get their input on suggested tire size. I was thinking 255/35/22..but I'll see what they have to say. Talking wheels/tires is somewhat of a foreign language to me (and I apologize for my lack of knowledge), but is there anyway for me to know if I would need centering rings prior to purchasing the wheels? Thanks for the offer, if i need them I'll certainly purchase from you.

All GLK's are hub-centric. You won't know until you get the rims. It's just a little ring that fits on the inside of the rim - some need them, some don't... don't have anxiety over it... it'll work out for you...

So I just called TireRack and they told me they could not suggest a tire size to me because their system only shows that a 20" wheel is the largest wheel that would fit properly on a GLK. I told the guy, I know for a fact 22s fit on the GLK because I've seen individuals on our board with 22s. He insisted he could not give me a tire size, so if anyone knows of anyone that can suggest a proper tire size for 22x10...it would be greatly appreciated. I know Verodder is running 255/35/22...so that's what i was planning on going with because I'm nervous the 265/35/22 may rub. Thanks in advance for any suggestions!

That's why I posted these phone numbers for you last week! Don't call TireRack. Call Brabus and ask what tire sizes they would recommend? Just pretend you're interested in purchasing a set of their 22" wheels (just make sure they're identical in size to the set you're getting) and pick their brains for the correct tire sizes!

I told him to call TireRack - sorry, missed your info in the post for Barabus

Doing research to find out what wheels fit the glk and came across this gem. Best 15 minutes of my day lol

What a racist post. Ridiculous nonsense like this doesn't belong here. Go back to the rock you live under, racist

Exactly

Sometimes it's wise to check the dates on 13 year old threads to see if it's a rat hole worth jumping down.

The lengths some people will go to find something to be offended by. Unreal.

This forum seems to be filled with children
