: It seems the best chance is with something no less than 20mm offset. But the key is really the shoulder profile of the specific tire used. Can anyone specify cetain 225-50/16's that are on the small side or with more "sloping" shoulders?

Hold on there, pardner... there are only two reasons to put a really wide tire on a car:

1) Performance: you want ore lateral grip and better braking ability.

2) Appearance: you want to look like you've got a muscular car with big manly (or womanly) tires on it to show how tough you are. See for examples.

Now, with that in mind, realize that tires that actually "perform" are of specific construction. This means things like low-profile, stiff sidewall, and "broad" shoulders - category #1 above. These are not the characteristics of the average all-season or family-car tire.

Tires with a "sloping" shoulder would generally be somewhat below the standard for "high performance" tires (not to mention "maximum performance", the step above). So if the tire would have the characteristics that a "sloping" shoulder tire would have, it would be "big" just for looks, therefore category #2 above.

Now, since you've got an E28 which is practically the ultimate "Q-ship" or "sleeper", we know you're after performance. If, for reasons having to do with the offset of the wheels you happen to own or an (understandable) reluctance to trim your fenders, a 225 will rub then you would quite simply go with a narrower tire like a 215 or even 205. The best choice of tire is not always the widest. Think about it this way - what would you expect to perform better, a "Pep Boys Special" 225-section tire or a 205-section Pirelli P-Zero? It's not the width that counts, it's the rubber.

Check out> for their tire recommendations at the performance level and price in which you're interested.
