Can someone explain what difference wheel/tire size makes to a car's
	
	acceleration
	top speed
	road noise
	economy
	road holding
	handling 
	ride
	etc.

why and how much??!! 

Also what the different numbers mean:eg. 185/60 HR 14 80 H tires
on 6 J x 14 wheels, alloy/steel etc.

And are there any physical limitations on the wheel/tire choice for
a given car?
