So far wear is pretty much non existent but it's only been 4 months/3500 miles and I had them off road twice last September and they performed as expected and can't wait til the snow melts a little more and hit the trails. I have the load range C so they will be tested this spring but on the road there's very little if any more sidewall flex then my D load rated Nittos and on the hwy they still are quite stable but also remember my 3rd gen weighs 600-800lbs less so E might be a better choice on the heavier 5th gens.
......my center caps are just off till we get a little warmer temps to finish re-painting them but yes,they don't look awful without them.
