For a motorcycle traveling at speed v (in mph) when the brakes are applied, the distance d (in feet) required to stop the motorcycle may be approximated by the formula d 0.05v^2 + v. Find the instantaneous rate of change of distance with respect to velocity when the speed is 42 mph.
No, thats a lie, and the law: the max pressure must be listed ON THE TIRE. You just aren't looking for it in the right place, but its on there. You really need to RTFOM This is not rocket science, if you cannot figure this out then give your bike to someone that can for chrissakes.
As the first responder indicated those are sizes and don't equate to pressure. And the rating on the side wall of a tire is MAXIMUM PRESSURE that the tire will safely withstand. It is not the recommended inflation pressure by any means. NEVER inflate to the pressures indicated on the sidewall. Check the owners manual or your dealer for the correct pressure for your particular bike.
Style, mostly. Rear tires are normally a little wider, due to the other thoughts expressed here.BUT The biggest reason for those really fat rear tires is just plain looks. A really fat tire just does not turn in the same way a narrow one does. It makes the rear sluggish. Power? Not the real reason at all. Most of your braking power isthe front wheel. Instead of putting down the power, it's doing the reverse - at the same rate or better. Many of the older cycles (and some of the newer) run the same size on both ends. HD touring bikes are a good example. There's others.
d' 0.1v + 1 Convert mph ft/s, then substitute.
