Excessive tyre wear
My wife drives the GLC.
The mileage is 10700 km. I was preparing to take the vehicle for wheel alignment.
Lo and behold the front tyres esp left have reached the thread indicators.
How is this possible? Anyone else have this experience. It is a RHD vehicle and the tyres are Bridgestone Dueller MOE.

quite normal. Runflats are softer tires, and MB alignment geometry wears tires quickly. The trade-off is exceptional stability. I have 23,000 miles on my C250 and it is on it's 3rd set of tires, which are nearly due for replacement themselves.

Hi, 10700km is poor.
I'm in Australia where the bitumen is coarse and road camber can be severe. We have travelled 18000 km in our 250d, mix of city and country work, not much dirt driving, all sealed.
I am at 50% wear, so I expect around 36000-42000km from set of 4.
I also give the car "some stick", so I do push it and enjoy "driving ", but I do use adaptive cruise control extensively.
We are using OEM Pirelli Scorpion Verde run flats, MOE. Cost here around $550 AU, each.
We had BRIDGESTONE on two other brands, not run flat, and found them to be noisy, soft and they " let go in the wet" very easily.
Around 7000km I had to have a front end align, as the outside left front was scrubbing out. Align was out, rotated tyres and much better. I also monitor tyre pressure and run around 36-38psi, not the 32 suggested on 20" rims. Higher pressure gives better handling, more rubber on road under emergency braking and minimises wearing out the edges when plenty of tread in the middle is left.
If you are going to replace tyres, look at the Pirelli and consider buying from EBay a set of TPMS, like 'Orange ' brand. That way when tyres changes you can have the sensors fitted to each rim, batteries in them are sealed and last around 5 years. Fit the reader in the cabin and you have live info on tyre pressures and temp for each of the 4 rims.
Hope this helps, our car is RHD too.
Great car, good economy, sadly no spare or wheel jack !
Cheers

Well there may be some truth in it.........
With all wheel drive the rolling diameter of all four wheels needs to be similar within a very tight tolerance. Can lead to issues with transmission if diameter of wheels is different.

Yes I too have been told that there are instances where you might need to do this.
We replaced one tyre at around 9000km. Did not need to replace any others, car now at 18000km, no issues.
If in doubt replace 2 and fit two new ones to front, allows for 4matic allocation of % to front, which is higher that power delivered to rear - it's not a 50/50 split.
Also Michelin UK web site has a good article on rotation, suggests diagonal rotation for 4matic, front left to rear right & front right to rear left. Suggest rotations around 7 to 10000 km ? Not miles ?
Here is the UK site, lots of good info.

Good luck
