I have an '05 DRZ400SM and want to put some more off-road capable tires on it. I've read all kinds of threads about changing wheels and suspension and quite frankly don't have the time or money for it, nor am I motivated enough. The stock rear tire is 140/70-17. I've found a Metzeler Karoo 2 that comes in both 130/80-17 and 150/70-17. I'm assuming this is a stupid question but would either of these tires work? Do they not fit the rim because its so wide? Pretend like you're talking to a moron.
