So, if I get a tire blowout, I don't think one spare rim will be able to replace every rim type I have, right? Even if it is temp till I get back home?
Most generally, you're only going to have rim damage on a front tire, because the rear has a mate that should carry the weight until you get stopped. If you're choosing one style wheel to carry, I'd pick an aluminum steer wheel, no tire. Less space required, and only 40-45 lbs.
