Picked up my new GLC, Prem Plus, AMG line recently and loving the car very much. Got a few extra's of 20" alloys, real leather, intelligent lights and 360 camera. "I thinks thats it?"

I traded in a GLA which was cramped for a tall guy with a hard ride full of rattles. None of this mattered when I put my foot down but further arm joint issues left me wanting to get back in a bigger, taller more comfortable vehicle.

I have two friends with a GLC so I'm aware of what one's like and the famous crabbing issues too. "The GLA does it too BTW" Mine came with summer's on and will be changed to all-season's later in year. The factory have put back the installation of all-season's on the production line to October now "if your one that is waiting?"

So then, whats it like? The cabin isolation from the road is very good, I hardly notice the state of the roads anymore, I can hardly tell the engine is running, quite the opposite of the GLA but that was a different animal. The interior quality is much higher, plastics quality is way superior.

I had Prem+ pack in the GLA but the GLC version has more options, nice to have gas struts on the bonnet again too, overall I'd say a huge leap in refinement from the GLA.

Planned Mods, I have fitted a stainless "dead" pedal and have a Sub and dashcams to fit when time permits.

I'll finish up with a quick "Hello" to the forum.

Nice one. When you say came with summer tires. Which ones? My dealer didn't say anything about installing new tires. I have Pirelli Scorpions. And welcome. And congrats!

same tyres as yours, but their are all-season versions of these available too, I'm assuming the softer compound ones will have "all-season" written on them?

i guess mine are summer, i was under impression that in UK all tires will be all season since there is no really summer usually. i guess i was fooled by the dealer for not even mentioning that those should be changed. oh wow.

You should not have a problem getting the all-season tyres, just wait until the crabbing & banging starts later in the year and complain about it. Dealers have all been informed what to do and how to get you tyres to reduce the issue.

..and that's just the question I have, do the new tires you guys are getting "reduce" the issue or "eliminate" the issue. I'm only buying if they eliminate...

MB UK only caved in and admitted there is an issue in the latter half of February this year. When the tyres were finally made available it was already so warm the OEM tyres were again becoming flexible enough to mask the problem. I had my tyres swopped from OEM Hankooks to Michelin Latitudes recently and the only noticeable difference is that the All-Season tyres are quieter and offer a smoother ride. Not unsurprising really since they have a lot more sipes and a less aggressive tread block.

To be totally clear, alternative tyres will not eliminate the issue, they just serve to better mask the problem due to their increased flexibility. All right-hand drive GLCs (and any other RHD models for that matter fitted with the 4MATIC drive system) are likely to have this design fault. The GLC was developed as an LHD vehicle since these have the greatest market share. For RHD markets the car isn't designed from the ground up all over again but is merely a conversion of the original LHD design. All the steering gear has to be put on the other side of the 4MATIC's front differential but there is not as much space in this area and it is this restriction that does not allow the steering geometry to stay within the Ackerman range. It is this incorrect geometry that causes a build up of lateral forces when the steering approaches full lock. In warm weather all tyres flex sufficiently to absorb these forces although those with lower sidewall profiles to accommodate bigger rims are inherently less flexible so will exhibit the tyre skipping phenomenon more readily. The RHD car has a design fault and it is highly unlikely MB will do anything to address it any time soon other than offer you more flexible tyres to mask the build up of lateral forces. What nobody knows yet is the effect these unwelcome forces are having on the rest of the drivetrain. If premature failure is the result I'm sure MB are hoping it is outside their 3-year warranty. It certainly makes a good argument for a 3-year leasing agreement on these particular cars.

Lucky for Mercedes no matter how much they mess up on cars, the image the brand gives potential customers is valuable, then there are all other great reasons for buying.

But slowly I have seen people consider other car makers. Now with Alfa Romeo making a come back, some of my friends held out on the GLC for the Stelvio.

Today I done a 100 mile motorway trip and it was so so comfortable, I am still tweaking seat settings etc., but very relaxed and chilled I was.

Had some great 90's club tunes on the Burmeister, no need for silly high volumes as the car is so quiet, and thats 100miles closer to being run-in too.

My Cambridge Dealer replaced the tires free of charge to all season. Got Vredestein Quatrac 5 and on the way home that's a totally different experience. Felt so much better. Just in case review for those here Vredestein Quatrac 5 tyre review | All-season tyres test 2016/2017: top all-weather tyres tested | Auto Express

Actually did anyone got their tire fit kit ? I didn't get one originally cause Pirelli were run flats. But looking at the new tires I don't think they are. Probably need to contact dealer again and ask ...

19 inch all seasons still not available for GLC43, not too concerned as I won't have them fitted until October/November, all agreed with MB and dealer.

I agree odd, I didn't just take the dealers word I called customer services to confirm. Will speak to dealer again this week as I can get michelins with the correct tyre ratings and sizes in all seasons.

Headquarters sent me a tirefit kit for Verdenstain tires. Hopefully won't need to use it. :)
