305/30/20 vs 295/30/20 on a stock GTS?
I won't pass MOT if I dont replace rear wheels on my car. Sadly, I don't have any more time (due in 3 weeks) to order matching tire in MO spec... and I have OCD and don't want * or N0 spec tyres on my Merc. However, getting one size larger set with of Super Sports 305/30/R20 with MO is possible where I live literally next day... stock is full. No wait.
Question: does this 1cm make a huge difference on a stock 9.5" rim?
295/30/R20 stock Pilot Sports look like this:

Just a clarification:
You mention 9.5" rim. I thought the GTS rear OEM rim is 10".
The Michelin Pilot Super Sport 295/30-20 necessitates a minimum rim width of 10 inches, while the 305/30-20 demands a minimum of 10.5 inches in rim width. Considering the horsepower, cornering capabilities, and overall performance of the GTS, IMHO, installing a tire that does not snugly fit into the rim is unsafe.

dagn, I might be wrong with the rim size... This page says it's 11" at the back, actually. My point here is that the 295 tire looks stretched on this rim anyways and was wondering if anyone tried 305 on this setup. 305@11 seems a pretty common setup looking at other car brands (from mustang to 911s...) by doing quick google search.

I have 275/35/19 PS4 on front and 315/30/20 PS4 on rear. All wheels are stock AMG GTS rims and i have never had any rubbing at all. I found the tires being larger in front of the car tracks better. As for the 315 rear just fill the wheel well nicely......

I was planning on the same sizes for my next set of tires. Paul, do you have a pic looking down the side of your car for reference?

305 at the back... what a difference. I was pissed off that I must trash my 295s (because of local laws - no matter the mileage or condition - 5 year and out), but boy I'm happy I did so... maybe it's because it's new, or maybe I'm trying to justify the expense, but the improvement is very noticeable - ride is so much smoother and there is so much more grip now. From what I noticed there is no difference on the speedometer vs gps indication - as before it's dead on - gps vs dash shows exactly the same at constant speeds (I guess all AMGs in Japanese specs have that?).

BTW, I have not had any issues with rubbing or any thing else. The garage i bought the tires from mentioned the Michelin tires are very squared so they tend to sit on the wheel in a very centered position, don't know what he meant by this but also mentioned the side walls are also very stiff so there is no chance they would come off the rim. These are the max sizes. He would definitely not go bigger than 315/30/20 on rear and 275/35/19 on front.

I don’t think I’ve ever P4S without an XL rating which gives you the stiff sidewalls.
I remember having an older Sl, and I ordered the Super sports and they were not XL and they wiggled all over the place.
