FYI:
Overall height difference
50 series = 24.48 inches
55 series = 25.23 inches
Roughly .75 inches taller tire
That rules this out for me and Maxtog...
Ah, because of leg reach, eh? Tell you what, buy new tires and ship them to me and I will adjust the standing height down by a little bit and send them back to you. It is not something I would do for everyone but I would help out a fellow forum user if I could. It might take me a few months to 'reduce' the radius of the tire....
