We have a 2007 GL 450 that came out new with Continental 275/55/r19 tires, They were replaced with Michelin Demaris 275/55/r19 tires by Raben tire at 26190 miles, After approx 5000 miles Raben rotated the tires, We noticed that they a little noisy and were featheredgeing, At 33749 Raben replaced the tires and had D Pat align all four tires and they replaced the air ride pump under warranty,After about 4000 miles the tires started featheredgeing and were rotated, Man after a few more thousand miles the tires were so noisy you thought you were rideing in a old 4x4 pickup with monster mudder tires! Dpat replaced tires under the MB goodwill assiatance program at 48869 miles with a discount! At 52546 miles D patrick rotated the tires and were starting to featheredge, I took it back after a few thousand miles and they thought rotating would not take care of the problem of featheredging and being very noisy! It now has 64863 miles and I am taking it in th D patrick for a message that the brakes need attention! Has anyone had similar tire issues? Are Michelin tires not compatable with a GL 450? Should I go back to Continental tires? The dealer and Raben tire have been wonderful to work with but I am throwing up my hands!!!!!!!! What should I do?After 3 sets of very noisy featheredging Michelin tires and the Continentals that came with the vehicle, It now has only 64863 miles total is this a good track record?

If you go here ...

http://www.michelinman.com

and enter your vehicle, you'll find ...


The name of the tire you purchased is 4x4 Diamaris®

You'll note in your owners manual you're supposed to use tires with MO specification.

Go here and note which are "OE Tire" with "Mercedes" listed ... and you'll see a conflict between Michelin and Tirerack.

It's good to understand, of course, than any of these tires are 25K mile tires at best ... as Mercedes has designed.

I have a 2008 GL 320 CDI. I just put my 3rd set of perilli scorpian zeros on at 86k miles. I have been able to do over 40k miles per set. I do almost all highway driving. I have been pretty happy with my tread life.

I bought the "H" rated for my second set a and just put them on again for the 3rd set because i was very happy with them

I see no difference between the V rated that come on the car and the H rated that i replaced them with. They are identicle look and tread pattern. The H rated are about $80 cheaper per tire.

An H rated tire is rated to 130mph, and the V rated for upto 150. I go no where near either of these speeds

Difference between H-rated and V-rated is often nothing but initial tread depth, the V-rated having less ... which creates less "squirm" and consequently less heat, which is what causes failure at high speed.
