295/30/19 Michelin ps4 fitmment
so I ordered Tires from tire tack always and then take em to Costco they usually charge 15 bucks per tire mount n balance they full it up with nitrogen 60 bucks all 4 best price in market. But since I m changing size from 285 to 295 on my e class they r being very picky oh we don’t want to b responsible etc etc I told them my car my choice but they just don’t wana do it. Same thing when I went to good year spot. These r only two shops I know they use nitrogen air in tires.
Thank you!

So your saying the 295/35 actually is better fitment than the stock fitment ?
Can you please post a few pics of the tires on the car I would love to see how it looks,Thanks

Diameters:
255/35/19 = 26.03'' (Front)
285/35/19 = 26.85'' (Rear)
295/30/19 = 25.97'' (Rear)
So, the 285 is 3/4''+ large in diameter (not sure if this will cause an issue with sensors in 4matic with this size difference, but might).
The 295 is only .06'' different and won't cause a problem and is actually "better" in terms of sizing as you want the front and rear to be as close as possible in diamter.
In my opinion, the correct sizes of the Michelin PS4S to run on these cars are 255/35/19F and 295/30/19R. Stock heights you will be fine as the 295 is just over 1/4'' wider than the stock 285 size.

so are your dimensions accurate, Thanks
In your post (post #8) you mentioned 285/35 which is why I brought it up.
Michelin makes a 285/35/19. They do not make a 285/30/19.
The dimensions I listed above are all accurate to what is listed there.
The OEM 285/30/19 diameter is 25.73''
It’s funny I was washing the car today and did notice the rear tire is smaller than the front in height , it must look better with the 295/30 -19 also , thanks again for clearing that up

Thanks I appreciate it , I was thinking on post 8 the 285/35 was stock size that’s were I got confused,

Once I run through the OEM pzeros (which are garbage in my opinion) I am getting the ps4s in the 255/35/19 and 295/30/19 sizes.

255/35/19 = 26.03'' (Front)
285/35/19 = 26.85'' (Rear)

PS4S are great! What an amazing upgrade from stock Pirelli P Zero.
I ordered some Forgestars 19 x 8.5 +28 F and 19 x 10 +35 R
The wheel company recommended a 245/35 F and 275/35 R tire combo...but that will result in the rear tire having a slightly larger overall diameter...
so I ordered Michelin PSS 245/35 F and 285/30 R which have identical overall diameter of 25.8"
TireRack also called me to verify the size since it's not what they recommend....
I just want to be sure they won't rub before I confirm the order.
Thanks in advance.
