I'll be doing slightly taller tires for sure. I think the limiting factor will be tire/strut clearance as is the case with my current Escape and the Bronco Sport, which both share suspension characteristics with the Maverick. I've currently got 235/65R17 (29" tall) on my Escape and while there seems to be plenty of clearance in the wheel well, there's only about 3/4" of clearance between tire and strut. I've read of Bronco Sport owners running 235/70R17 (30" tall) without issue. I think 30.5" will be the absolute max tire diameter without modification. All that being said, I'm hoping to try and fit 255/65R17 on my Maverick with no lift.
