I have a couple questions on how to proceed with the rims & tires I am purchasing. I am going with 20 inch rims with tires 305/55 AT.

Will I need to adust the torsion bar? The place selling me the wheels says no adjustments necessary, simply bolt on.

Also, my dealer says that I would need to purchase software to reprogram the computer, $500.......Is this necessary?

Any information would be appreciated.

 

305/55 are 33in if i remember correct
if so u will not need to adjust

 

i have the same tire size, nitto terra grapler 305 55 R20, no adjustmnets required, but since I change them I appeared the signal that I have a low tire which is not true, is the computer that needs to be reprogramed.

 

Thanks for the info......
