helloooooooooooo, anybody home.............................................. ......

I am sure there are plenty of people home. BUt you asked a very specific question. Unless somebody has deviated from the reccomended tire size to what you are looking for you will get NO responses.

FYI...going from 275-55 to 275-60 is not reccomended b/c you have exceeded the 3% variance rule for tires. You will have approx 27 less revs per mile with the tire. Are you trying to save money or slow down the odomoter? Those are the only two reasons I could fathom for a rationale.

Also, can have an adverse effect on the performance of the car. I can't speak to the impact on the 4WD drive system on the ML, but you can really screw it up on other marks.

Maybe not just the 4WD system but the ESP too.

Interesting post. This size tire would fill up the wheel well better. I asked a tire guy for his recommendation. He recommended this size, although he admitted he had never fitted this size to an ML. Sexybeest, did you get this size?

I say do it... there's plenty of gap there to fill I personally would like to go with a bigger rim and maybe even lose some of the profile, and that I would guess, put even more strain on the car's drivetrain than putting on a bit larger tires. I say go for it. If you can put 20-26s with 305 size tyres on 4wds with no ill longer term effect... my .02 cents.

ML4 what are you talking about? Do you have any idea what changing the rolling diameter can do when you are exceeding the 3% threshold? In this case it doesn't seem like you do.

ML4me

Yes, you change your odometer, your speedo and put more strain on the engine to turn heavier, larger wheels. My hubby and several of his friends have the larger suvs [albeit not a benz] but a yuke, navi, and expedition specifically and they have those larger rims with no ill effects. Some have the awd, 4x4, limited slip and so on and so forth. I'm just stating what I think, based on my and my hubby's experience.

I had the same question and when i asked 2 places, Tirerack and tirediscount i think and they said i could go 275-60-17, That's the current size of my toyo proxes btw.

Here is their answers:
Tirerack:
275/60-17

Somewhere else:
- our data shows the largest tire size you can use would be 275/60-17. This will be a 1.1" taller tire but the same width you have on the vehicle now. Going to anything larger could interfere with suspension, steering components or the wheel wells.

But hey address nothing relating to AWD, ESP, etc.

All they really state is how much rubber can fit inside the wheel well. Have you thought about talking with the dealer to see if they have any experience with this? For example, reccomending it or not, warranty claim denials, etc.?????

Well, it seems you have your mind set on this so I will go ahead and leave this discussion and say best of luck to you.

You're right, they're recommendation does not take into consideration that it is for an ML Like you said, there must be some good reason why MB does not recommend this size.

Hi. I'm hijacking my wife's member name for the moment.

This is based on my experience with the subaru outabck AWD I used to have. When I had a blowout up front (and they have donuts for spares), you have to pull the AWD fuse so the default front 2wd would engage. Remember the donut is way smaller in width and diameter. This was necessary to use the donut spare w/o screwing up the drivetrain. If your flat was up front (which was the case for me) I had to rotate a good tire from the back, up to the front, and put the donut on the back. That way the 2wd would function properly on 2 same sized wheels and no harm would be done. This was in the manual. The logic is as long as you have the same size wheels all around, your awd is fine. Same would apply to lsd, as long as the same sized wheels are on the ends of your rear axle. ESP should follow the same logic.

Now I am not familiar with mb. Regardless, just keep the same size wheels all around and you'll be fine. Switching between 55 series to 60 is negligible. From looking at my wifes ml, there's plenty of room and you're not increasing the width any.

FWIW, I later switched from yokos 255-60-16 (standard size for the outback) to toyos 255-55-16 (the closest they had), and it worked beautiful. I even liked the slightly lower profile. Much better tire to imo.

On my expedition, I have 305/45/22 tires on a 22x10 rim (the stocks were 275-17" tire/wheel). My speedo is off by 1.5mph and the odo is certainly not accurate (shh!). There are several websites you can plug in your tire numbers to compute things like speedo differences, overall diameter and compare different tire sizes, etc. I know 1010tires has this calculator.

Hope this helps waylay any concerns with your tire choice!

Cool site btw!
