In my experience the automatic braking safety feature is way out of wack or at least needs some tweaking on most vehicles. Sometimes 2-3 car lengths ahead stopping and vehicles lock down the brakes and obnoxiously beep at you.
Had 2 sets of MasterCraft Courser AT2's on my Xterra. Rode well and had the AT look. Highly recommend if available in your size. Also I assume much cheaper.
Much more sturdy sidewall than it's predecessor the Viva 3. I'm a service manager for Walmart Acc. If the dextero is available in your area also a good budget choice.
All the lionhart's I've had the luxury of balancing have been horrendous. I can honestly say none of these were going on a Mercedes. Maybe you've gotten lucky.
