My mechanic gave me his NTW cost for 275 70 18s then told me to get them from Discount Tire for the warranty, rotation, etc. They matched it which brought them down from $257 to $229 per tire. Not bad savings x 5. Getting them installed in an hour. Hope others can use this.
Too bad you don't have 17's, if you wanted the C load tires instead of the E load @KillerBox posted above, they are a factory size for Jeep Rubi's. I think I paid about 500 for the Rubi take offs with 2k miles on them and 0 miles on the spare.
