wiper blades, 97 yukon?

[YukonRidin23]

he everyone, im going to go buy new wiper blades and was wondering whats a good size, or actually the largest. i read somewhere 18, and i think thats whats on there now, but they seem wayyyy to small. id like to get atleast 22 inch if not a 24, is there any problems with going larger on them?

eh.. your blade might hit each other.. or wipe past the top of the windshield...
