I have a 2011 e90 xdrive stock wheels. with 225/45 r17 tires.
I'm getting tired of bent rims and bubbles. just found a bubble in my new Continental Extreme Contact DWS's. can I put a tire on with more meat to help absorb the bumps. please don't tell me to drive slower I already have every suv in new York up my ass.

235/50/17 would give you the most meat. But then again you are in NYC, Somalia has better roads then NYC and that's with the bomb craters.

How much more meat ? Do you think it will help ?
Last year I bent 5 rims so far this year I have at least a bubble on an almost new tire . If this keeps up I'm going to have to sell it and buy another truck.

look at the height for 17in wheels

Thank you
If I WENT With a wider wheel could I use an even bigger tire

No, you have to keep the height of the tire close to stock. You can go down to a 16" wheel to get more meat.

This is something that I have read a hundred times. But why it is I don't know. If I don't care about the speedometer (it's wrong anyway ) and I have the clearance in the wheelwell what effect will a larger diameter cause. Also would a wider tire help.

It has the same effect as gearing up the car. You'd be surprised how much difference this can make and the strain it can put on various parts of the drivetrain. Don't know if you've ever played around with radio controlled cars, but if you have then you probably know that most powerplants and chassis have an optimal range for gearing, exceeding which is a recipe for melting something (usually gearboxes). Additionally, adding more tire adds a good amount of rotating mass compounding the problem described above and slightly reducing braking effectiveness. Its all round a bad idea.

Look for a tire that is famed for a hard and resilient sidewall, over inflate by just a couple of psi (roads in Greece are definitely worse than in New York (and Somalia for that matter lol) and this is a cheap trick to protect your rim and sidewalls a bit better) and see how you go. A wider tire shouldn't really make any difference, excepting of course that if you stick with the same percentage (40/45/50), then of course it will cause a taller sidewall which may or may not be helpful bearing in mind all the above.

Makes sense. I already run extra pounds of pressure which may have saved the wheel.If given the fact that I rarely put the pedal to the floor would an extra inch of diameter make that much difference.

Hard to say. I run 19s and avoid 'every' pothole, sometimes even if that means waiting for a gap in oncoming traffic to do an overtake maneuver of the pothole lol.

I've actually just bought a set of 19" BBS CH-R in black, and if I regret it and they get bent, I will go to 18s and call it lesson learned. The 19s on the car now are a little bent, thanks to previous owner, I figure I am more adept at avoiding damage than he was. At least I hope so, or I just wasted a couple thousand bucks on rims and tires. :/
