Our Jeep has new rims with back spacing. The 4ź" backspace, creates a gap between the tire and the tailgate. As the result, the wheel is not stiff and accepts all the vibrations while driving. Spare wheel simply shakes giving annoying sounds. The only solution is to get larger bump stops and voilŕ, annoying vibrations and noise from the rear disappear forever.
This Daystar product has proven to be very low quality. After a couple of spare tire removals both new bump stops dropped off. Protruding foam tips used to attach to the tailgate were gone. It did not make sense to purchase the same product again. With a few wood screws, I decided to combine the original bump stops with a piece of a new one. I cut them both so that after putting them together I got the correct length. New custom made, combined tailgate bump stops perform the same task, but have much better quality.
