How to read this table

Every combination here is one the manufacturer published for that kit on this vehicle — tire size, wheel width, bolt pattern, offset and any trimming note, exactly as they wrote it. Open “what the manufacturer wrote” under any kit and you will see the source string the figures came from.

We do not interpolate. A kit verified for a 35 tells you nothing certain about a 33 — clearance depends on backspacing and turning radius, not on the tire being smaller — so only sizes the manufacturer actually listed appear. A size missing from this page means nobody has published it, not that it will not fit.
