    Hi everyone,

    I have owned my E320cdi merc for 3 years now and i am very happy with the car, but for the fact I seem to be replacing rear tyres every 12 months, sometimes every 10 months.

    I have been buying various premium tyres (conti, good year) and use recommended pressures for 225/55/r16 according to inside of filler cap (2 person load).

    I know the car is heavy but didn't expect to replace tyres at this rate and wondered if anyone else has experienced this. I drive about 10k per year and drive sensibly.

    Thanks.

    Even wear across the tread or worn more on the inner/middle/outer part of the tyre?

    yes it can be common depending on how and where you drive. motorways don't do much to the tyres compared to lots of corners, stopping/starting etc.

    when we first got our 203 we were getting 10k miles to a pair of rear tyres. I mentioned this to an MB tech and he asked how we were managing to get that sort of mileage as most of the cars they saw (stop start city driving) were getting 4-5k miles from rear tyres!!!!

    If it's even wear across the tread, you have to accept it as normal whatever miles you get.

    Was getting 18-20k on a similar vintage CLS 320.

    I find MB's recommended pressures to be ludicrously high - current car is 44 psi for light loads. Feels awful!

    32-33psi worked absolutely fine for 2 years on the CLS, same on this car... And most cars I've owned beforehand. (Actually handled better too, less vague steering, etc).

    recommended pressures are to get the fuel economy figures up and the emissions figures down, as we all know. theyre much less to do woth handling and braking safety nowadays, especially as many tyres have a max safe pressure of about 44PSI, so how would you be able to increase that for heavy loaded scenarios, I wonder?

    Indeed they are Pete. Just surprised me that MB dealers continue the myth by pumping my tyres up at service time! :roll:

    For a loaded car, my car is supposed to be 46-48. Bonkers!

    10,000 miles to a set of rear tyres is unacceptable.
    1. Examine your driving habits and make adjustments if necessary
    2. Use Michelin Premacy tyres.
    3. You can expect 30-50,000 miles fromMichelin.
    Good luck
    Regards

    I used to average 30-40k from my e220cdi in same size, michelins or avons...rotate front to rear though to even out the wear

    rear tyre wear

    Thanks for responses.

    I might start to switch front and backs from now on as mentioned by Ricardo- fronts last 2-3 years but last set of Avon zv5 and Goodyear Efficientgrip only lasted 8-9k miles for the rears. I set pressures as 29 front and 32 rear but might start to increase by 2psi and see if that helps. Tyre wear depth is fairly even but I noticed a bit more of the tread pattern lost near outer (wheel arch) side, but I do keep monitoring tyre pressures. MOT has not revealed any suspension issues - I have mine set on comfort not sport setting but probably won't affect tyre wear ?

    Driving style is Ok - keep to speed limits and 600 miles motorway driving every month and rest 15-20 mile drives in between.

    I was thinking about changing to a cheaper tyre this time - westlake rp28 (£50) or rRotalla RH01 (£66) or Kumho Ecsta KH31 (£69) or maybe try out an XL tyre (Avon ZV7 for £82). I am interested to know if anyone has experience with XL tyres and if the reinforced tyre would help on a heavy car like mine (2200kg)?

    Might buy tomorrow (black Friday) - might get a good deal if I'm lucky.

    Regards,
    Steve.

    That sort of driving should give you pretty good mileage out of tyres... unless you drift around roundabouts regularly!

    My CLS was on Contisport 3s, and I'm on target to get 10k on the Goodyear (ie quite soft) on the back of the C63.

    Checked mine this morning, MB had put them back up to 38psi all round - dropped them to 33 psi and noticeable improvement all round!

    on the 203 I had. goodyear eagle NCT5 lasted 10k (except the original factory fitted ones) as did Pirelli P6000 and Michelins (cant remember which ones now) were over 50% more expensive, yet only lasted 15k miles, both with dad.

    I live in a different county now, I had the same car, nothing changed on it geometry adjustment wise, I am a far harder driver as far as tyres are concerned, yet I could still get more mileage than dad got from 'identical' tyres so I also think road surfaces vary. when I go back to see my parents I can 'feel' the surface change and the car (any car) seems to grip better around there than it does at home.

    it may not be the cause, but it could be an aggravation of the problem, if there is one

    I've recently had similar problem hence googling if others experienced it too!
    My rear (265/35/18) tyres have about 3.5mm left on them after about 4k miles. I think thats crazy. Bought new tyres in Jan 2020, its 10 months later and i need to start thinking about replacing them already.
    Certainly didnt expect them to wear so quickly. I drive approx 50-50 motorway/city.

    Fronts have plenty left in them but are smaller (245/40/18) so cant swap them.
    Use the recommended pressures so 29psi front and 32psi rear but need to top them up regularly. Would lower psi make the wear curve plummet? I mean if i had 26psi or 28psi on the rear the tyres shouldnt suddenly wear 50% faster, right?

    What are the best wearing tyres you ever had on your E class rear?

    What happened to 40k miles from a decent tyre.?? Seems more of the less for more story.I used to get 30k + out of khumo tyres on my g in kenya,where roads are not great and 80 to 95 k out of firestone 10.00x20,son our fleet of nissan cpb12 trucks !! We retreaded with bandag and they guaranteed original k,s on wear. Some will chirp on on grip,safety but I had no issues with my khumo tyres on g ,oyota d/cab or pajero??

    Interesting thread is this. I say this because I've recently bought a 2013 SL350 and the rear tyres are supposed to have 39 psi in them as do the fronts (I think) I thought at the time that this was a bit excessive. The ride is quite firm and they are run flats, which I'm going to change to standard once they wear out. So my question is should I drop the psi and to what level. My previous car was a Jaguar S Type with 18 inch wheels and the pressure recommended was 30 psi but I used to run them about 28/29
    Your thoughts please :confused:
