I want to measure the speed of Tyre of tractor or the shaft to which it is attached with high accuracy of about 2% and than fed rpm of the Tyre to the Arduino. What are the possible options with me? If anyone can guide me i shall be very thankful.

Optical (reflective: place one or more marks on the shaft or tire; break beam: one or more openings in the wheel), magnetic or inductive (one or more magnets on shaft or tire), mechanical (encoder or switches - not recommended due to wear), and probably some more that I don't think of right now. Contactless would generally be preferred.

Can you please let me know if any of such sensors are available online?

All of them are, and in many different versions.

One can only guess why you would want to do this but, depending on the tractor, it sounds like it might be a contradiction in  terms. Some other source of the r might be a better way to get the pm, maybe the power take-off

Can you suggest me any good website where i can find class-1 components?

All of the above have all kinds of components. Read descriptions carefully, to make sure whether a specific component suits your requirements. You can also try going directly to the respective manufacturer's web sites.

You haven't mentioned any website.

Oh, that was another thread then. It's asked so often.

Well, start with the usual suspects. Amazon, eBay, element14, digikey, rs components, AliExpress, taobao, adafruit, sparkfun.
