My friend suggested CONTINENTALPROCONTACT TX235 /55 R19 101V SL BSW N0, softer and quieter too, Says he got 35,000 on them Yokohamas I have 70,000 on them but there a little noisy and stiff.
I hvae 2011 RX450h with 100,000 miles , the Car weights a lot and batteries are very heavy.My lexus does have a harsh ride which I wonder is result of worn shock. I since own it have already put in two sets. Once while under warranty and second was my expense . I am now wonder is it the Yokahamma 60k tires are to harsh. I recently started driving the car 40 miles to work and notice the harshness . Could be the tires which I run at 37psi or the shock are the wrong size chose by Lexus or it's a truck and it is what it is?
