check postings about

tank treads (chains) and how to animate such things
(OK - a bicycle chain is very small compared to such big things …)

A quick but inaccurate way would be using the Curve modifier to bend an array of chain segments (using a Path). If the curve radius isn’t too small, mesh deformation isn’t apparent and the end results might be realistic enough for your uses:

Here is the Tank Truck tutorial. This is for identical tracks. Bicycle chain alternate in shape so this method works but you will need two trucks.

sorry forgot to to correct some normal!
look at it from close and you can see one bump missing on the gold chain
you need to select faces around that bump and flip the normal then it will come back ok!

is there a simple way to animate this like rotating

have fun
