Quote sae70 "The height of a tyre is very much effected by the width of a rim. On my Vitara's I ran with 31" Cooper STT's but because I'd stretched them onto a 10" wide rim they stood only 29.5" tall. There's an optimum width rim for each tyre manufactured and I guess 7" is the one for my 255/85/16 tyres"
So with my 1 inch wider wheel the height should be around an inch less than yours . This equals a half inch less to push against the light cluster or rub on the rear bumper and both of these problems did not prevent you from using the door normally . Added to this my offset will cause the tyre to meet both points further out than yours which may help as both bumper and lights curve away from the door . Might get away with it me thinks .
Theory is all well and good i suppose i need to get out and try it in reality but its good to discuss things as it helps others wanting to modify , i spent ages trying to find out exactly how big i could go without a lift and eventually gave up looking for a definite answer . When i bought wheels and tyres i was dreading not being able to fit them unless i spent hundreds more on a lift .
