Hi all. First time posting so thanks in advance. I plan to put adaptors on my 05 TJ X to put on some 18" Sahara wheels. I'm not sure if I should get 1.25 or 1.5 inch adaptors. I'm not looking to offset the wheel any further. I want to get the right adaptor that ensures the lugnuts all snug up and there are no gaps between them. Anyone know what stud size would be?
