285/35 and 265/35 tires for the sedan
Hey guys,
just wanted to hear from those who went up 2 sizes (as shown in the title) from the factory setup 265/35 r and 245/35 f. how are they holding up and what are your thoughts so far?

that's great news ! I will also add to you guys and confirm that it is indeed the best improvement I did so far!
however, what are you guys running? 35s sidewalls front and back?

yes 285 have been fitted and confirmed quite a bit. One or two member have ***295*** on the back but I don think they/the car wand wheels have been tracked with that oversized quite yet. This is why I am curious about how well they are holding up in regards to tread wear and aggressive driving

some larger will not rub but the bead is pulled in too far and the tread is not flat at proper pressure.
But this does not keep original ratio between front and rear so best is 255/275

What impact will going up 1 size on the front (255) and 2 sizes on the back (285) have?
If it should be 265 on the front to keep the same ratio, that is only a difference of 3.5mm of tyre height (assuming 35 profile). That's less than the difference between a worn set of tires and a new set.
Is it better to go with 255 and have the tread flat or 265 and match the diff with the rear tyres?

the increase in tire size/width allows for more rubber and a larger footprint/ contact patch allowing better traction. And as anyone that drives any type of motorized vehicle knows, traction is a good thing!
with the amazing HP and torque the AMGs are putting out the 265 is too narrow and breaks traction, especially wasting the power (power but no movement)
and yes yes as long as a tire company makes a 265 or a 285 in and 18" tire.
the 265/285 is the width

It's nowhere near that simple.
Say you have 2 sets of stock 19" OEM rear wheels. Mount 265 tires on one set and 285 tires on the other. Fill them up to the same pressure (recommended 33 psi). Both sets will have the exact same contact patch area. Exactly the same. The only difference will be the shape of the contact patch (285 will be a bit wider but shallower).
Now, to get the "more rubber on the road" that people think rider tires get you, you need to lower the pressure. What worries all of us that don't agree with going wider is that when you mount such a wide tire on a (relative to the tire size) skinny wheel, you are moving the mounted bead position of the tire further to the inside of the tire and ultimately allowing more sidewall play/movement. Lower the pressure to allow for the larger contact patch, and you only amplify the issue.
I won't even get into how this sidewall issue affects the shape and evenness of the contact patch.
Again, saying you are able to mount a larger tire on a wheel is VERY different than saying the wider tire functions are it should.
And on a side note, I guarantee you that the vast majority of the performance improvement that people perceive when mounting 265/285 tires is that you are mounting fresh tires that automatically will perform better than the worn out tires you are replacing.

Essentially yes. Based on manufacture recommendations of both wheel and tires a 275 is the largest the suggest for the rear due to the 9.5" wheel width, but 285 will fit and does fit and has been used by several members. check out a web site called tiresize.com, plug in your current tire dimension and play around with adjusting the three different aspects i.e. 265/35/19 vs 285/30/19 it will visually show you how and what the numbers mean as well as explain the above about sidewall ratio and what not.

Second, as said above and almost every other time this comes up on here, just because a wider tire fits on a given wheel and functions on a daily basis does NOT mean it gives you any sort of performance advantage. If anything, a tire that is too wide for a wheel will exhibit worse performance than a smaller tire.
Think of it using this analogy. I can comfortably fit between a size 10 and 11 size shoe. I can also technically fit in a size 12 shoe and walk around all day without tripping over myself. It is a bigger shoe and has "more rubber on the road" with its bigger footprint. Which shoe would you rather go running in? One that has a slightly smaller footprint but fits like a glove, or one with more "rubber" but that will flop around on my foot when I try to move around quickly? Anyone with their head screwed on straight would want a size 10.5 over anything else. And if they were set on wearing and needing the grip of a size 12, they need bigger feet (ie. you need bigger wheels).

First, to get this out of the way, the question was never if 285 tires would fit on the rear. It's been said on here numerous times that they should fit. The concern has always been that 265 tires are wider than what is recommended for the OEM front wheels.
