I've decided to spam the forum again, and I'm going to try to get it all out in one day so I can disappear and leave you all in peace again. I've finally admitted that my tires are dangerous and need to go and want to go ahead and get them bought and on my bike. I swear I think the tires on there are almost original, and they are cracked to hell and back, so anything will be an improvement. I don't ride too terribly spirited as there are too many issues I'm slowly working out.
I've read through what I can turn up in the search. I'm leaning towards a set of Metzler Lasertec's, but they look like they will run $210-$250 shipped just for the tire. I remember seeing another model recomended that was cheaper, but can't turn it up this time around.
I'm fairly committed to the 3.25 x 19 and 4 x 18 tire sizes, as that seems to be the best fit from what I've read. I'm not committed to a look, just a well made tire at a good price.
