I have an 05 roaster and want to put 19 inch wheels on it, how do I determine what the offset is? thanks.

 

try +20 all the way around.

owner's manual:

see page 252 for stock offsets.

you'll need to use the calculators posted above to figure out what offsets you want, since stock is less-than-optimal, to say the least.

by the way, width is the determinant for offsets, not diameter/height.

 

thanks, I'll try to make sense of all this..

 

this is a good calculator for side by side comparison
