I want to make sure of what I'm hearing here, so please forgive me if I seem a bit pedantic in my questions. I'd rather not spend the money on tires that I can't use or won't fit well! (and, yeah, I've searched, but haven't come up with anything that directly addresses my questions)
My 1988 has 3 15x6 rims and one 15x5.5. (don't ask, I picked it up cheap off craigslist, and it's a bit of a basketcase. One mis-matched rim has been the least of the weird issues the thing has had) I have been scrounging the local junk yards for two more 15x6 wheels in the same style (yeah, 5 rims, so I can have a spare). I've run across two different styles of steel rims, both styles appear to be 15x6 (but one style is available in 15x5.5, but it's not chrome, it's just grey paint, but I digress).
Assuming I can find the right style of rim (so they match, got to keep up appearances!) of 15x6 inch steel wheel, will 31x10.5 tires fit on that, or am I better off not running such a wide tire, like a 30x9.5 or the 235/75s that came with it when I got it? I have to admit that I'd like to get a bigger tire if possible (the 31s) because it would simply fill out the wheel wells better, appearance wise, but if I'm just asking for trouble and annoyance in trying to make that work, I'd rather not and will just go with the biggest tires that will not be a hassle. If that's the 30x9.5s, awesome, if I'm really better off just sticking with the 235/75s, so be it. I'm just looking for some definite information on what will comfortably fit on the 15x6 inch wheels I have and not cause me problems. The beast isn't lifted (that I've seen any sign of) and I'm not interested in lifting it either. Thanks in advance to any who reply!
