Which is the better combo to have and what are the pro's and con's
on each if any ?

 

smaller rims are better for offroading. you wont scratch them on stuff as easy

 

IMO, 20 inch tires have a lower profile, less sidewall height and ride rougher than 18 inch tires. Also, check the specs, some of the 20 inch rim and tire combos limit the max payload of the vehicle. Not sure why that is, probably has to do with desiging a wheel and tire for looks rather than functionality. Also, when it comes time for new rubber, 20 inch tires are generally more expensive.

 

Also 20' tires cost so much!

 

yeah, 20ft tires are REALLY expensive.

When should you change your oil?

 

Hell yeah, monster truckin baby...

Odd, very odd....

 

20'' rims are generally heavier, cuts into acceleration, extends braking distance.

 

The alloy rims are lighter than the rubber used for the tires.
