I am still deciding what wheels to go with my ride either OEM five spoke or 20" wheels? The only thing stopping me is the ride quality. If i decide to get 20's how much difference is it going to be?

 

It depends. The size of the rim itself is not the sole determining factor of ride quality. Take into account the tires you'll be riding on, and the weight of the wheel. The stiffer the sidewalls, the stiffer your ride will be. The heavier the wheels, the less effective your suspension will be. There are too many variables to play with.

 

20" will force u to run 35 series tires, which in turn will worsen your ride for sure.

however 20" does visually look best on ls430 big body.

19" with fat 40 set up is kinda nice medium, but like I said before; 20" is just gravy for ls430.

 

is it possible to run 40 set up with 20's
