Hey fellow GLC43 drivers..... I finally got around to ordering the pirelli tires and they should be delivered to my place tomorrow. I have a mobile installer coming by to install the tires and I have a question. Did you guys get an alignment done after installing the new tires or did you just put on the new rubber and went about your business? I remember ItalianJoe1 stated that some of the factory specs were off with the GLC43s and I was wondering if I should take mine to an independent shop since the front tires of my Continentals were wearing pretty uneven on the outside tread.
What are some of your thoughts?
Did you go with the Scorpion Verde or P-Zeros? I may go and have my alignment checked as it seems like my fronts aren't wearing correctly and I didn't notice it before, but looks like my steering wheel is a tad off. Haven't hit any large potholes or anything, so...???
Anyway, I would go with an alignment to make sure everything is "ok"...a little insurance for your new tires.
Wheel balance will be necessary. I assume your mobile installer can balance the tires. I did not do an alignment on my GLC as other threads here indicate that toe-in, toe-out is no longer adjustable.
Hey guys reporting back after my Pirelli Scropion Verde 21 install. First let me say, to all of you guys that were guinea pigs in ordering the Pirelli Scorpion tires and providing feedback, you guys get major kudos!!
I had my tires installed yesterday and the installers stated that I would not need an alignment. "Their" opinion about the continentals were that since they were summer tires, the crabbing/skipping when turning and cold weather cornering and stuff were unevenly wearing out the tires since they were not made for Winter driving. When they took off my front tires and I got a chance to inspect the edges, they stated that I literally had about 800 miles left on them before I had to change them and I only have 4600 miles on my truck.. Also, I didn't know that the Macan comes with 21in summer tires too, and that most of their owners also pick the Pirelli Scorpions as the installers have done quite a few of them too.
Since nobody on here has posted a pic of how the tires look on their GLC, I wasn't really sure what to expect. I must say, I REALLY like the way the scorpion tires look compared to the Continentals as they seem to be more aggressive looking and meaty. Last night, I went to my local Walmart and parked in the garage which is notorious making my GLC have the crabbing issue and I didn't experience any of those symptoms. Also, this morning I took my son to his school which has an out door parking lot which likes to make my GLC do the crabbing issue and nothing today. I know Pirelli tires are known to wear out faster due to the more lower profile stance but this is by far the best mod/change I have done to my truck, even more so than the Jb1 piggy-back. I don't think I am going back to summer tires now, and I will keep these tires on until I am ready to turn back in my lease. Plus the ride is similiar to the continentals if not better.
Hopefully, some of you guys that have more mileage on the Scorpion tires can report back in on tread wear and provide feedback.
Swapped out my set with the Scorpions as well after 17k miles. Fronts were bald & rears we so so. Ride does feel a lot smoother (placebo?) & the crabbing issue has not occurred once. The extra 10mms and the chunkier tread pattern does give a beefier look which I dig. Here are some quick pics on the driveway with my old iPhone 6. I definitely needed an alignment & I'll post the report later when I have a chance to scan it.

Here's the alignment report, if anyone wants to geek out. Camber is always an issue with MBZs.
Thanks and the tires look great. They will probably replace my summer Conti's once they go bad, so I won't have to buy two sets of wheels/tires. Love the GLC for the most part and plan on keeping for awhile.
Can an "expert" chime in on the alignment report here? I'm curious why on the front the camber "actual" reads the same (-1.3), but the right is showing in "red" as out of spec, even though within spec. Also, on the rear, the camber "actual" is different for the right (-1.4) and left (-2.1), but within spec. Do the "actual" numbers not being the same or close to the same cause weird tire wear, would probably be my ultimate question?

The reality for the difference in Camber specs is because there is simply no front or rear adjustment OEM! Only solution is to be able to state “within spec” by having broad parameters.
We saw the need therefore to reinstate from the early 90’s front Camber and Caster along with rear Camber (and extra Toe) facilities.
The K-MAC patented design simply replaces at the same time the 4 front and 4 rear highest wearing suspension bushings, providing precise single wrench adjustment accurately (under load, direct on alignment rack).
Ongoing adjustment capability for day to day commuting, encountering high cambered roads, altered height through load carrying or lowering, fitting wide profile tyres/wheels or curb knock damage.
Another popular kit manufactured is set of uprated rear bushings for the 6 multi-link arms. Significant improvement to rear end traction/stability, especially when applying power to lane change/overtake.
GLC 43, 63:
Front Camber & Caster kit #502816 $545
Rear Camber (& Extra Toe) #502226 $480
Delivery $30 one kit, $20 each additional kit. PayPal, Visa or M/Card
interesting, but the cost is kind of deep for both front and rear, not to mention + the installation fee., the cost will over $1400.
Also how do they work with the air body control? the car will adjust ride height according to different speed or drive setting. To my understanding, ride height will change the camber. if the car dropped, how do they work together?

Re cost - example $480 compares more than favorably with say rear upper Camber and Toe arms that advertise at over $600. Yet are labour intensive to fit, adjust and have the disadvantage of further reducing the important clearece top of tire to outer fender when wanting to reduce costly, premature inner edge tire wear.
K-MAC lower arm adjusters also at the same time replace the 4 front and 4 rear highest wearing suspension bushings. Precise single wrench adjustable. Rear kit includes bush extraction tool allowing to fit on vehicle.
"How do they work" ....as above they simply re - instate adjustability allowing to "change tire contact angles" to compensate for signs of uneven wear.
Has anyone looked at the Continental ExtremeContact™ DWS06 - 265/40ZR21, 295/35ZR21 - All-Season option? From what I've seen these have the highest tread wear(560AA), 50k mile warranty and only cost about $200 more than the Scorpion Zero Plus. The only downside I saw was that the 265's only have a W rating but like mentioned earlier, who's going to hit 168 anyways. Just wanted to hear your thoughts as my ContiSport's are needing replaced after just over 10k mi. Oh and has anyone had any clearance issues with the 265/295's?

I was just looking into these yesterday as I've always heard good things about the DWS, but I don't see a 21" size for the fronts, which is odd. I see the 21" rears on the Continental website, so what gives? Where are you seeing the 21" fronts for this tire? Being in the US, the speed rating isn't such a big deal as I'd probably never hit 168mph, anyway. I personally would probably rather give these a try than the Pirelli's, but still have another 10k miles on the stock Conti's and that will take a year or so for me.
Thanks. If you look up that tire and specific size on Google, it gives a date of May 2015 before you click the Sears link. I can't find this front size anywhere else and it looks like the Macan forums went through this exercise a year and a half ago with the end result of that size not being offered for the fronts. It's either an error on the Sears website (which would NOT be a surprise) or it's old stock that perhaps Continental only offered the size for the DWS06 for a limited time/basis. If you look up that specific tire size on the Continental website, it does not come up for the ExtremeContact DWS, it shows only 4 max or ultra high performance summer tires. Either way, a bummer...back to the Pirelli's when needed.
After only 6,500 miles, the front Continental ContiSportContacts are worn to the wear bars! I cannot find any all season replacements in 21". Has anyone found a good substitute for the Continentals? Tire Rack has Dunlop (new and pricy) and Pirelli P Zero summer tires.
Don't get more continentals. Their tread wear is abysmal.

Yep, I own a Macan with 21 inch wheels and participate on that forum. Turns out it was a simple typo by Sears.com.
There are not a lot of tires to choose from in the 265-40-21 size. You might want to check out Atturo AZ850's. While they are not a well name brand, you can get a set of 4 in the correct 21 inch sizes for $536 delivered from Tires Easy.com. One of the forum members on the Macan forum has tried them and says they are every bit as good as the well known brand names.
Another choice is the Michelin Pilot Sport 4S. Tire Rack sells them and they are great tires, but they are expensive. And they are MB spec in the correct 21 inch sizes.
I ordered PIlot Sport 4S from my local tire guy (surprisingly better than Tirerack without even haggling!) Went with the 265/40R21 in the front and the 295/35R21 in the rear. Checking the spec and it is within 1%, less than 1 MPH difference and the revs/mile difference front to back are only 5 versus 4 for the OEM sizing. I will let you guys know first impressions. Hoping they are reasonably quiet, good performance and get more than the 12k on got on the Conti's.
I ended up going with the Michelin Pilot Sport 4S's in the 265/295's. It is amazing the difference they have made compared to the stock Continentals. Far quieter and the ride is amazing. Feels better in turns, on uneven roads and doesn't hydroplane on heavy rain roads like those other skis. Also haven't noticed any clearance issues with the size increase. I would highly recommend.
Are you still Happy with the Michelin Tire on your GLC 300 AMG 43 ? Do You have an SUV or a coupe?
Needing to make some decisions on new tires. Having the same issues as everyone else.
Thanks
I was thinking about getting some matching 20" front and 21" rear wheels for my 2018 GLC 63 so I could get Michelin Pilot Sport A/S 3 tires. They have the rears in the correct size for the 21" rears (295/35) and correct ones for the 20" fronts (265/45).
ive been having people put the scorpions on for all seasons...
you want crabbing.. try sport cup 2 tires on the new AMG GT63S sedans.. I drove one today..its 20 degrees outside..worst Ive ever seen.. not designed for sub 40 degree weather
