I'm just wondering here...

1. What is the fatest low pro tire that would fit a stock sporty rim and swing arm without major mods.

2. Not as likely but, what is the fatest tire and rim combo you could go with again without doing a whole fat tire kit?

If I were going to do a bunch of mods and $$ I would just purchase a 240 kit or something but, thought about trying to find something a little more aggressive/fat for the rear. I did an internet search and searched the forum but seems to me it's only a fairly larger tire 160/70 w/o doing some sort of kit.

Some one school me, Please!

Thanks,
Jason
