Last year I purchased an 09 RRS with 20 inch rims. But there were Off Road tires like BFG AT that were available at the time. Using semi snow tires like the Nitto Grapplers I had one flat on a steep grade and had a long walk back to town. Actually bent the rim did not blow the tire. Hopefully the tire makers are making OFF Road Tires by now for this tire size as more and more SUV brands are going to 20 inch rims.
