I'll try to help you a bit here . Last year i bought a set of 17" kmc diesels for my truck but with the positive offset the inside lip rubbed on the calipers. i ended up exchanging the wheels for a set 17"motometals with a negative offset and they cleared . I think 16" might clear but it will be super tight and offset will be very very important. 17" will clear easier and there are plenty of drag radials and slick type radials avail.
