What size tires can I get on Factory 403M wheels

Hey guys,

I'm planning on getting rid of my runflats and getting some wider tires for my 403M wheels, just wanted to know how wide I can go.

I was planning on getting 235/35R19's in front and 265/35R19's for the rear.
I 'm pretty sure these will fit, just wondering if I can go wider.

If I can, I'd like to get 245's in front and 275's for the rear but I'm not sure if they'll fit.

Thanks

Widest tires within spec for OEM 403 wheel (widths, 8" front and 8.5" rear):
F: 245/35-19, 8.5" recommended wheel width, 8-9.5" allowed
R: 255/35-19, 9" recommended wheel width, 8.5-10" allowed

This is the recommendation from the tire manufacturers. You might fit even wider tires but i wouldn't recommend it for either tire performance or looks.

If you have xDrive you must match the front and rear rolling circumference, then there is only one option besides OEM sizes:
F: 235/40-19, 1% taller than OEM
R: 265/35-19, 1% taller than OEM

However this rear tire is not within recommendation for the rear 8.5" wide wheel.

^ this.

Why do you want wider tires on you stock wheels? Certain brands like Michelin PSS tend to have a wider section width compared to other brands and look "beefier" if its a visual thing rather than a wider contact pad thing.

That's why I'll change my wheels.
There's no way I'll exceed the recommended tire specs on wheel width.

It has nothing to do with look... Wanted to get wider contact patch without changing wheels.

Guess I'll stick with the stock tire sizes.

Thanks

Plenty people went plus 1 265/35/19 and 235/40/19 my question is wouldnt the recommended measurements perform better than what I just stated? But the 265 does look more aggressive no?
