305/40s on stock 22 in wheels?
Would a 305/40 on the stock 22in rims fit? I'm looking at picking up a GLS63 for my wife and it has the Pirelli Pzeros and we live in Michigan. Looking to replace with something reasonably priced and right now I can get Pirelli Scorpion Zero Assimetricals (305/40) for $280 off of Tire Rack. The mechanic at the MB dealer thought they would fit but gave it the old, "I can't guarantee they will fit" and I really don't want to have to deal with returning 4 tires to Tire Rack. Thanks for the insight, it is much appreciated.

you'll be fine, OEM AMG 22" multi spoke wheels are 22x10, the tires will bulge a bit though just FYI, but 305/40/22s will work fine

I wondered about a larger tyre size too, the OEM 22” spoke rims are 10.5” aren't they, i thought 295/40 as can get in Merc spec M01 but its a W rating rather than Y as they're the tyres for the G Wagon.
I feel like my GLS looses traction easily and skips in the rear wheels on bad surfaces hence the thought of a different tyre?

My main setup is 23", 305/35/23.
My other setup was 22", 305/40/22 -- pictures here: https://www.hrewheels.com/gallery/me...-brushed-clear
My winter setup for a more narrow tire (better in snow) for 22" is 285/45/22 (yes 45 profile, it fits my GL63 no rub).

325 will fit, but you will get a bulge.

It’s about time to replace my stock Pirellis on my GLS63 with factory 22”s. So 305/40/22 is okay to run and won’t mess up the speedometer or transfer case?

If the tire is taller, it will throw the speedo off by whatever percent difference in rolling diameter. Wil it damage your speedo or transfer case, no.

1) It will not damage your speedometer or transfer case.
2) transfer case damage happens when you have two different rolling diameters. Both front and rear tires will be exactly the same. You are just moving from 31" diameter to 31.6" diameter.
3) when you are going 20 mph, your speedo will show 20.4 mph. 60 mph, it will show 61.2 mph, 90 mph, 91.7 mph. You are fine.
Your DME Stage 2 Tuner might be able to update your tune to account for 31.6" tires vs. 31" tires, but it's not even worth it. You can get that kind of variation between different tire manufacturers and also brand new tread vs. old tread.

Hey Carlos, you have some great options.
My winter setup is YOKOHAMA GEOLANDAR A/T G015 285/45/22 - smooth, quiet, can go over any potholes without worry. This is Severe Snow Service Rated tire that is also an all-season. Really can't get better than that with a 600 A B rating.
For 295/40/22 - I'd suggest: PIRELLI SCORPION ZERO ASIMMETRICO (420 A A) or CONTINENTAL CONTISPORTCONTACT 5 SUV (420 AA A). The Continental has better specs.
If you want the ultimate long lasting tire, you have to move up to 305/40/22 - MICHELIN DEFENDER LTX M/S (720 A A). I mean a 720 rating and A A. Michelin tires to me are one of the easiest to balance and ride smooth. You also pay a premium.
I have P Zero's on my Panamera and they are sticky, but harsh ride and don't last long. I personally think the Asimmetrico is much better of a overall tire for general purposes.
305 will look more bulky so if you want a sportier look, 295 would be better.
You can also stay 285/40/22 and just go with the PIRELLI SCORPION VERDE ALL SEASON (600 A A).

I wondered the same about W rated tyres compared with Y rated. A lot of the 295/40 size with M01 designation are a W rated from the new model G63 AMG whereas the 285's are mostly Y rated for ultra high performance but I feel my GLS63 skips on the bad quality uneven surfaces of UK roads and just feels out of sorts on the 285 Pirelli P Zero until the tyres have had a good run and are warmed through so I was considering a 295/40 Goodyear Eagle F1 which is an Asymetrico tyre but W rated.
I just want the car to feel more comfortable on the road surfaces than it does now

I just purchased the Pirelli P Zero All Season's in 305/40/22 and will have them installed on 1/2/2021. Let you guys know how they feel in a couple of days.

I too am looking to shift out of the OEM 285/40/22 into something better for winter, perhaps just a good all season instead.
We were in the some light snow last week and the car felt horrible.

So far so good. Have not felt any rubbing, driven at speeds over 90mph and no issue so I am pleased!

Yes they had no issues with balance and honestly since installed they have only been driven 50 miles. Initial reactions are good, they do poke out a little more then the stock 285 but to be honest it's really not that noticeable to me. The stance looks great and the ride was obviously better vs the stock summer Continentals.

Update, after 1000 miles on the Pirellis initial thoughts are pretty damn good, however, with the wider tire, I am now finding more little rock chips on the bottom panels above the running boards. Very upset with myself as a proper respray will cost more then if I stayed with the stock tire size. For anyone switching to this size, I would highly recommend a clear wrap (like Xpel or equivalent) on the lower panels.....just my 2 cents.
