Yes, indeed! The Firestone Firehawk SZ50EP is the best tire I have ever used in over 28 years (Edit: 30 years - I am getting old!

) of driving! (I have not [yet] tried the Pilot Sport or Pilot Sport AS, and it may be as good or better from reports.)
I have raved enthusiastically about the SZ50EP many times in many posts!

Please do a search and see my earlier comments on it. The only caveat that I have heard is to not use it in snow conditions.
Greg's Falken Ziex 512 is also a good recommendation, but having compared the two directly (both on my Q45, but in different sizes), I would go with the SZ50EP first, even though it is more expensive. The SZ50EP is grippier in wet and quieter - the balance "lasted" more miles as well.
For my M45, I really regret that it is not available in the correct size (245/45-18), so I will try out the Pilot Sport or Pilot Sport AS sometime early next year.
In a few months, I will change tires on my wife's Acura 2.2CL (if we do not trade it in for a G35

), and I plan to get the SZ50EP in a 205/55-16 size for it. Basically, I want the best wet weather performance I can get, for when she and my son are out in rain.
