I currently have the stock SAS wheels with the Goodyear territory’s. I’m switching to Toyo Open Country RT Pro’s 35x12.5r17. I’m also switching to wheels that are 17x8 with a +55 offset. So compared to the SAS wheels which are 17x8.5 with a +30 offset I figured I’d need 1” spacers…but now I’m wondering with the new wheel also being .5” narrower will I need a 1.5” spacer? Thoughts? Thanks
