I haven't had them on my LS, but a number of years ago I did have the Bridgestone Turanza Serenity tires on my wife's Jaguar S-Type. I remember that they performed very well. My wife doesn't drive aggressively, but they did well in wet conditions and wore like iron.

 

Although I have never driven in a car with the Bridgestone I just installed the Pirelli Cinturato p7 all season plus 2. I bought them based on forum feedback and couldn’t be happier. Since I live in the South, snow performance was not important to me. If you are looking for a quiet, good wet weather and dry touring tire for your L, I think the Pirelli a is great choice. Have them on my 2017 L model with air suspension and they are a perfect fit for my driving.

 

I have these on my son's VW CC and my wife's infinity Q50. I love this tire. High performance, quiet and lasts linger than Eagle lol. So I'm changing all the control arms over xmas. Doing alignment and I just put on a new set of these 235 50 18. If these wear great like my other cars I'll be sure to let you know. I know I should have went wider but I'm still checking the control arms/alignment. GL!
