Tires
 

Why are the front tire profile 50 and the rear 40 ? Why not 40 all around ? handling problems like under/oversteer ? :confused:

The 40 and 50 represent the height of the sidewall as a percentage of the tire width, In order to keep the rolling diameter (and sidewall height) the same on the front and rear the wider tire in the rear will have a porportionally lower aspect ratio.
