thinking of putting beefier tires on my GLC43 21 inch wheels.
like it to look more aggressive like the GLC63 with the same size tires.
i know they won't look exactly the same cuz of the wheel width of the wheel and all, but it will definitely look better. Plus I don't like the ride of the run flats. i think they should fit ok without any issues. any advice or tips are welcome. thanks ....
(run flats are available if interested, like new)
Stock size
fronts=255-40-21
rears=285-35-21

New size
fronts=265-40-21
rears=295-35-21
interested in this as well but not sure if they will fit.

Wondering if anyone has a 63 out there with an agressive fitment... Im looking to increase the size for the front tires to 275 and the rear to at least 315 or 325 wide. I would have custom wheels made so far the fronts would be 20x10 ET30 and the rear 20x11.5 ET28. Just wondering if you guys had any experience with fitment regarding this.

you absolutely do not need your wheels that wide for those tire sizes. I am not a fan of curbed wheels, so when I went to 275 wide tires in front, I actually went down to 9" wide wheels versus stock 9.5"
on the rear, I am 10.5 wheels wrapped with 315" tires.

if you choose your tire width first, your next challenge is deciding on the matching sidewall profile that would match your tire height.

In my case, I went down to 28.7" tall tires so I am now o.6" shorter than stock tires. To achieve that my tires are 275/40 and 315/35.

Every single choice for width and height was my decision, including my wheel offset which is 15 front, 25 rear. I also have 22" wheels which are same height as stock at 29.3". I kept my front tires at 265 wide for that set in order to match the stock height with 295/35/22. rear is 315 wide there also.

this is my 22" with 265/35 in front over 9" wheel with +20 offset

this is 20" x 9" wide wheels in +15 offset. 275/40 tires wrapping it.

315 from the rear

A bunch of tire specs i gathered.
