What size fits?

I posted this on here a couple of weeks ago in another thread; I have found with 235/60s (TAs) on stock 15/7s (cop car wheels in my case) mounted to a Duster (Valiants/Scamps use the same front fenders), you need to trim the the corners back (roughly at a 45) on the flat flange ahead of the front fender wheel openings and roll the wheel lip up where the rear of the tire can contact it at certain times under full steering lock. A friend running 215s on the same wheels doesn't seem to have the same difficulties. 225s might clear also, depending the brand.
All in all, even the 235s are quite do-able, I have been running mine for several years.
