2017 MB GLC 300
Crappy Pirelli's
We bought our MY17 GLC300 4Matic a couple of months ago and drove it around town and put about 700 miles on it. Then we drove it from the Sacramento area to Utah to visit family and did a fair amount of driving while in Utah as well. We drove 80-85 most of the way and noticed a vibration through the steering wheel at the higher speeds. When we got back we brought the car in with just over 3k miles. MB of Rocklin attempted to road balance the tires with no success. The tires were clearly defective but Pirelli would not warranty them. Not sure why MB is contracting with them. But MB of Rocklin is installing a new set of Continentals free of charge. 
I was really happy with the car otherwise. Absolutely the most comfortable seats I have ever sat in, in a car. And we got between 26-28 mpg the whole time.

Does anyone know what the correct tire pressure should be? I have a placard on the driver door jam stating 35 front/ 42 rear cold. There is also another recommend tire pressure placard on the fuel door saying the same size tires are 32 front/ 32 rear cold. Mine is equipped with 235/60/18s.

The door jamb shows pressure assuming fully loaded vehicle. The fuel filler for is for normal situations
From the factory my pressures in the rear were similar to yours. I changed to 34 all around and the ride is much better and I will be staying with this pressure.

Hi, Yes would be great to find out more re these Vredestein tyres. How they perform, any crabbing, handling, etc. Assume they are summer tyres and not RFT, or All Season ones. We do not have them in Australia and some here are considering importing some to try out. Any help / feedback would be great.

Sure, I'll get the full details of them when I am home (I work in London Mon-Fri). From the photos I took at the dealer on Saturday they are Vredestein Quatrac 5 tyres but I dont know any more as to whether they are summer, or all weather.
I had read previously about the issue with tight turns causing the grabbing/skidding effect on the inner wheels due to the locked diff. As far as driving goes I found no noticeable issues. The car was impeccable, but perhaps thats because I've just came from the older model Volvo XC90 and this car is night and day in terms of refinement. To be fair my own car (i.e. the one my wife and kids don't normally use) is an older front wheel drive Alfa Romeo which has had an LSD added later and that also can cause similar issues on full lock.
Worth reading a bit on this site, this confirms MBUK now moving to Vredestein...

And they are 255/45 20" - well on the front at least, I think all 4 are the same size. You might just see them in this photo....

None of the oem mercedes supplied tires come with any type of warranty. Go figure. Ours were worn out in 19,000 miles. Replaced them with Bridgestone DriveGuards from Americas Tires. 60,000 mile wear warranty and road hazard for $140.00 each out the door. They are RFT's.

They were the 235/60-18 Scorpions Verdes. I went for a test drive when the MB mechanic and the first thing he did was check the tire pressures, they were all 33-34PSI.
I will provide feedback on the Contis.

Alan,
Thanks for that. Those Vreds are all-season tyres.
I have been monitoring the crabbing discussions for a while.
I have a GLC 43 (bought last Nov) but with 19s (Michelin Latitude Sport). I've not had any major issues but I bought a separate winter set (Pirelli Scorpion) as I use the car for ski trips to Austria - so haven't had the necessary cold with summer rubber which seems to cause the problems.
I'll go past my local dealer in London tonight and see if there are any GLCs in and look at the rubber.

That's not true. My GLE came with 265/45/20 Pirelli Scorpion Verde tyres, 3 of which were with deformations and the service tried balancing them many many times before they said that two of the three are ok finally but the third is too asymmetrical and they changed it under warranty. Actually the representative of Pirelli in my country was responsible for the change, not the MB dealer, but anyway the new tyre is not fully ok again, some vibrations can be felt b/n 90 and 105 km/h (only!) mostly on the brake pedal. Never Pirelli again, my winter set of Michelins are much much better, and even though the same size look like a wider profile tyre, i like them much more.

Anyone know is the 55's would be ok as a replacement - 1/2" less sidewall - anyone have any feedback on this idea?

We have the 19's and DriveGuard is available for them. As far as 55 vrs. 60, check with the tire seller. They should be able to tell you.

2017 MB GLC 300
Follow up: I picked up the GLC yesterday after the dealer installed a set of Conti CrossContact LX Sport tires. I am amazed at the difference, I cannot believe how much smoother the car rides. We didnt even realize how bad those Pirellis were until now. I thought I would only feel the difference at highway speeds but the difference is felt everywhere! I will no longer consider Pirelli when shopping for tires.

I've got the Pirelli Scorpion Verdes too.

If the old ones are RFT, these will be also. Cars that came with RFT's have no spare. Dealer would either have to supply a spare or a repair kit. Also there's no storage space for a spare.

Yikes
That is good to know. My Pirellis have 20K miles on them and are about worn. Is that normal? Does anyone buy anything other than RFTs and go without a spare? I am thinking about it. Replacing tires every 22k miles is a pain.

I've heard tires installed on any new car built don't have good rubber on them. Just enough to last 15-20k miles. If it's true I don't know why. 2nd set you buy outside like tire pros rubber lasts longer. Im sure someone on here knows better.
I'm running 2017 GLC 4matic 19 inch Conti RFT almost a year now bought new last 12/16 ride is smooth no problems keeping eye on them have 7k miles see how long they'll go. If I do switch later to regular tires it will be with Michelin LTX if I stay with RFT will be Contis again if originals hold up meaning no bubbles like Contis are known for.

There are more threads about replacing RFT's with regular tires, too. Problematic since there is no good way to carry a spare and repairing a flat on the side of the road is a pain. If you choose to go with "regular" tires some members say they'll just call AAA and have them send a flatbed to pick up their car.
Do a search using "Search This Forum" and you'll find plenty of discussion about it.
BTW, I have 18" Pirellis on my GLC with 2,000 miles on them. No complaints on ride or handling, so I'll see what they look like as I get closer to 20,000 miles.
