What Is The Offset On The Mounting Plate For Roadmaster Spare Tire Carrier # RM-2000-7?

Published 08/16/2023

Question:

What is the maximum tire diameter and width/offset that will work? Im wondering if using this combined with a Jeep offset spare tire spacer would work with a 235/65R18 51mm offset.

I reached out to Roadmaster who said the plate is 5-1/4" from the inside of the upright on the Spare Tire Carrier # RM-2000-7. Your 235/65R18 tire has a width of 9.3" and the 51mm offset is approximately 2" off the center giving you 6.65" inches approximately from hub face to the inside of the tire. So to use this you would have to also add a wheel spacer of at least 1-1/2".
