My FJ80 needs new shoes. I have a set of new Cooper Discoverer SRX M&S 245/65R17 tires that I took off my everyday truck because the wife says "too noisy" and I'm thinking that they would probably work OK on the LC. Not the best, but OK. I can also pick up a decent looking set of used Granite Alloy 17x8.5J ET1 wheels locally for $50 apiece (different lug nut?). My biggest concern is the ET1 offset. The offset on the 15" rims is ET8. Is that too much difference? Not looking to have to insert any spacers or anything like that. I'm running some BFG 33" tires on the 15" rims now, but don't really need a tire that big. Truthfully they are too heavy for me to change a tire anymore. After the 245/65s wear out I'll probably go with something taller again. Thanks for the help.
