well we bought it, TN it looks just like yours w/o the mods, with you having bigger tires what did you do for a spare since i's pretty tight with just the stock tire size?
Tires are Goodyear Ultra Terrain E rated......265-70x17's
Have 30K + miles on tires and are doing real well...great snow traction
Yes bought 5 tires/wheels when I switched over from the 18's...sold the 18's quick
Along with adding a RidG Ultra swing receiver mount tire carrier......wife hated it..sold it
So on longer trips....spare is behind rear seats...won't fit underneath
Link #2 is Bell Lexus.......best source I've found for OEM parts
