Just ordered a set of SRT replicas for the DJ. They are 20x8.5. Here is the question. Discount tire approves both the 245/45 and a 255/45 for the journey but i want to run the 245/50. Has anyone ran these with or without rubbing issues? It seems to be a common suv/cuv tire, cx-9, and toyota venza use it. Let me know, thanks.
