88LX rolled fender lips, no quads, will 275/50R15's fit with a 7" wheel?

[fiveohpatrol]

i've got 10.5" slicks on my 10holes and they do bow out pretty good so i guess 275mm which is wider than my slicks wouldnt be a great idea, i didnt even think of that, what a dumbass, ok, now a new question, i DO want to get nitto drag radials but the next size down from the 275's on a 15" wheel is a 205/60 i think, and i dont want to go that skinny, i haven't extensively searched but is there another tire inbetween? like maybe a 245 or 255? thanks
