Tomcj2 - assuming you're using the S/SV OE steel rim that's 5.5" wide because you said R15, here's the Stock rim and rubber vs your proposed set up, straight with fender line and turning circle to the point they get closest to the fender liners, with the gap dimensioned.
Since your rubber is only 3/16's wider (towards the fender) it's extremely likely that even at full travel you won't impact anything above the tire, all that's there is the fender liner, then a void behind that.
(had deleted this earlier, forgot about the scrub radius, using an assumed 2" - so top to bottom is, stock / yours / mine / my plan for summer)
TLR - you're good
