Tires for 2010 GLK
I have a question that I cannot find the answer too.....
So, it is disappointing the number of tire choices for the 235 and even 245 sizes on the 19" rim. And certainly, the tires available are not what I am looking for. I really want a more all-terrain tire for my Colorado adventures, rather than a high speed sports car tire.
But, if I jump up to the 255/50R19....the choices abound. Matter of fact on a couple of tire websites, this 255 tire size actually pops up the GLK as the vehicle.
I called TireRack and they said that jumping to a 255 would increase the tire width by 0.8 inches, or 0.4 inches on each side. They assumed the tires would be just fine, as there isn't usually a concern on small SUV's until the size crosses the 1.2" larger threshold.
But, I was wondering if any has put on the 255/50R19's?
.....or if anyone has already done this search.
Thanks for thoughts and comments.

But..... This will be an interest view for everyone....
Notice the differences in the three sizes. According to this website, if one stays below a 3% increase in diameter difference, then it should be ok. Also notice he similarties between the 255/19 and the 255/17....in every measuremen except sidewall height.
The GLK 350 2wd/4wd should come standard with 17" tires and sufficient sidewall height for a variety of conditions on/off pavement, summer, winter, etc.
19"-20" wheels and reduced sidewall height should be optional at the buyer's discretion.
You asked for an all-terrain solution. 16"-17" wheels & tires answer your question. Select a different solution at your own peril.

I had the Hankook DynaPro on my Touareg and those tires were awesome. Would love to have them on my GLK.

Skinny sidewalls will trash your 19" wheels in a heartbeat.
I have no idea if they are still made the same way, but I got 50k miles each out of two sets of Bridgestone Desert Duelers on my 1989 Trooper II. Including off road in Canyonlands and 200 miles across glare ice in Mississippi. Good enough for me.

You have freedom of choice.
I'll bite. What size wheels were on your VW SUV?

Will 16" rims clear the brakes?
.......
M-B offers a 17" wheel that does indeed fit the GLK. There may be others.

I pull the trigger on a set for my 19" rims. I did plus size up to a 55 profile, but I stayed with the 235 width. The ride is far better, yet maintaining a very stable stance.

If so, I would definitely check with the dealer could save you a couple of $$$
as for snowy conditions, I've made several trips to heavenly mountain, mammoth mountain and big bear mountain this winter season all in very snowy conditions...and the car handled great with the pirelli 19''...i saw 4x4 chevy silverados, and dodge rams, lifted toyotas etc... all struggling. slipping and sliding everywhere and my little tank was a traction trooper...gotta love that!!! but I do agree for the best off road experience, I would go with 17"...thats my plan for next season.
