The question says it all. It is for a geography project.
Measure from the cente of one bolt to the one across from it, I think jeeps are 5x4.5, 5 bolts 4.5 inches across. Check tire size, if their the same theyll fit. Tire size would read something like 225 75r 16
I don't think it will disensitize drivers but I don't think it's really going to help either. Honestly, I think the best way is automatic radars. You get caught on one on some random road and you get a letter ordering you to pay up the fine a week later. The wallet is where it really hurts people. That's the only time I ever see people slowing down: in sight of a radar. A school children crossing sign won't do it, but the threat of having to cough up a fine will. There should be radars on every road and there problem solved. EDIT: by the way I heard they'll only have those speed bumps there for a week as an awareness campaign. They're not meant to stay there permanently, so that would go against the argument of people will start disregarding it. I don't know if that's true though.
Check your Owner's Manual. Don't have the manual? Why the hell not? It's considered a part of the bikeget one soon.
