How would the Nitto 555Rs perform as everyday tires compared to the F1s?

thanks

 

Are you asking how they would "perform" as far as handling/traction or how they perform regarding longevity?

Traction/handling = They perform as well if not better in both instances. They are a softer compound so they will offer better traction.

Longevity = That is determined entirely by your driving style/# of track visits. With normal day to day driving with only a couple of Track visits, you should see about 10-12K miles out of them. As Track visits/burnouts increase, that # will shrink accordingly. I've run Nitto's on all my past Mustangs, I'm currently running them on my F-body (street rims), and my L. Other than the nasty "rock slinging" habit, the tires are awesome.

 

I'm running them on my daily driver. So far I've got about 100 miles and counting!

 

I would not recommend them as daily drivers. Wear rating is 100 as compared to 300 on the F1s. I got about 9000 out of my rear F1s, so I wouldn't expect more than 3000 out of the 555Rs. But since the truck is not my daily driver that should get me about a year. However, discovered to my chagrin the other day that the puncture resistance is not very good, either. Ran over a sharp object and destroyed one of my new Nittos. Waiting on a replacement from Discount Tire. If this becomes a regular event it could get real expensive in a hurry.
