wheels how does it make thhe car go faster than before
i am waiting to hear about ur anser aas soon as posiible

Want to answer more questions in the Technology category?
Maybe give some free advice about: Cars?
is the engine front mounted and front wheel drive? if so look at the drag cars of the Front engine front drive class they all have larger wheels in the front than in the back. that's to give them a better off the line grip on the road on the dragstrip. that same principle applies to front engine rear wheel drive cars which have big tires in the rear so as to give them a better grip. i don't quite understand the question as you haven't explained how the car is driven. if you could tell me if it's front wheel drive, rear wheel drive, four wheel drive, and in which part of the car the engine is mounted rear(behind the rear axle), middle (in front of rear axle but still behind front axle), or front(on or infront of front axle)i could help. larger wheels in the front or rear based on where the engine is mounted get more downforce, more grip, and a much better off the line time. as is mounting thicker wheels on the section to where the power is delivered and to where the weight is mostly distributed. is it on a leaf spring suspension? double wishbone? swing arm? all of this stuff is important too to know how speed is affected by tires, and by the road.

That's cool that you're from Iran. You'd want the wheels in the back to make it go faster, otherwise your car would flip over and stop moving. The other answer to this question has more detail :).

Do you mean bigger wheels in the BACK and not the front?
Because if that's the case, if you're going down and incline it's to make sure the car doesn't flip over.
The only way having bigger wheels in the front will make you go faster is if the car accelerates with some sort of engine and not just with gravity or you pushing it, and only with the front wheels.
As for a formula... well, arc length can be represented by:
arc = (radius of the wheel)(angle rotated)
or s = rΘ
A greater arc length = a greater distance traveled.
