I have fitted Wolf rims with 7.50 Michelin XZLs to a '61 LWB acquired last year. 6.5 inches wide instead of the standard 5.5 inch but more importantly, the inside of the rim is around an inch further out from the body . Screwed the stops which are to stop the tyre rubbing on the chassis on full lock right back. Now the limiting factor is the extremities of travel in the steering box. Did not need to adjust the drag link as clearance on full lock was same on both sides. An experienced Land Rover mechanic reckoned swivel housings would take it. With where the seal gets to on the chrome balls on full lock looks to me about as far as desirable to go anyway and tyres are well clear of chassis. Probably still would not rub if 235/85's were fitted. With significantly reduced turning circle compared with that that on standard Series rims, would not want to put original ones back. Note that the inside of 7 inch wide standard Disco 1 steelies is the same distance from the chassis as standard ones so would not want them on a Series LR either.
