Generally all cars have equal sized wheels but few like batmobile (the tumbler from dark knight) have larger rear wheel. What is the advantage of larger rear wheel.
The discussion revolves around the potential advantages and disadvantages of having larger rear wheels on cars, including considerations in drag racing, aesthetics, and vehicle dynamics. Participants explore various contexts such as street cars, drag racers, and fictional vehicles like the Batmobile.
Participants express a variety of viewpoints, with no clear consensus on the advantages or disadvantages of larger rear wheels. The discussion remains unresolved with multiple competing perspectives presented.
Some arguments depend on specific contexts, such as racing regulations and vehicle types, which may not apply universally. There are also unresolved assumptions regarding the implications of larger rear wheels on vehicle dynamics and performance.

[The more surface area, the less force per unit area. The less force per unit area the softer the compound you can use. The softer the compound you use, the stickier you can make it]
On the other hand if you are building a dragster, you want your front wheels to have low aerodynamic drag and to be as light as possible.
In the case of a Batmobile, the overriding motivation is almost certainly to look cool and to give an impression of "there must be some physical principle that they're taking advantage of".
