It depends on what type of racing you intend on doing. A typical 1/4 mile drag rear wheel drive car would have larger rear wheels for traction and smaller front wheels for less weight but this is only useful for the 1/4 mile RWD drag racing.
assuming we are talking about a rear wheel drive vehicle, the smaller wheels weigh less and provide the least resistance.
typically you want a a smaller sprocket in back and bigger one in front.. bigger one in back with stock in front will cause quicker acceleration small on back and big in front will cause you more speed but if you put a smaller one in back put a bigger one in front
either the wheels you put on are smaller or the calipers are bigger or even both :P
When you turn the front wheels, they skid sideways as they turn. The skidding wears rubber off the tire.
Swap to a bigger rear sprocket or a smaller front sprocket. It'll lose a little top speed but be stronger uphill.
So it can wear out the outer tread faster thus causing faster front tire wear which will help to sell more front tires.
if you want to subtract a bigger number from a smaller one, first subtract smaller number from bigger one add negative sign in front of answer you got
I think it helps with balance.
Smaller. It should run least to greatest.
You select a bigger rear cog. Whenever you see someone going up a hill on a bike they always seem to be pedaling faster than normal. With the cog on the back being bigger than the front the front cog spins faster than the rear. Im not sure how to explain why it makes it easier but a understanding of gear ratios may help you. Hope that answers some of your question.
It is more difficult to steer with big tires, they are smaller so they are managable, also the weight on a tractor and traction is needed in the rear
You can subtract the bigger fraction by the smaller fraction and then put a minus sign in front of the answer.
