OK, got my tires mounted today. No rubbing, no interference - so far. I haven't driven them very far or done any hard cornering with passengers, but the clearances look very good.
Side view to show 50-series profiles.
Rear shot to show extra width and pattern.
Close up on front. Tire sticks out an extra 0.4" from the rim, gives a bit more rim protection, especially with the rim protection bead on these Goodyears.
If I have any issues later, I'll post about it. No obvious difference in ride quality or noise, and the speedo checked out against a radar sign to to the same MPH. I'll do a GPS check on it later.
Worked for me, YMMV!
