I have 18,000 miles on my original Pirelli P Zeros (235/50 ZR18). At my recent service, they all had at least 5/16" tread remaining. Lately, the rear end has been acting squirrely when I punch it in 2nd or third - loss of traction and fish-tailing. The Ford service advisor (not real sharp) says it's just loss of traction due to tire wear. Does this sound right? Even in normal or sport+, it does this. I was wondering if the traction/stability control software needs looking at.

I've had those tires, never liked them for just that reason. They have no traction no matter how much tread is on them. It is loss of traction but not due to tire wear, they're just crap tires IMO.

The best I've found are NITTO NT555 tires. Those are now being phased out and replaced with NITTO NT555 G2 versions that have a different tread pattern.

I've had Pirelli P Zeros, BFG G-Force, Dunlap Direzza DZ100 (discontinued now) and Nitto's on my car Out of all those, the Nitto's are the best.

In order from best to worst:
Nitto NT555 - Highly predictable and excellent traction dry/wet, become unpredictable when wet and worn
Dunlap Direzza DZ100 - Highly predictable and excellent traction dry/wet, but lose predictability and traction when worn down dry/wet
BFG G-force - Highly predictable and excellent traction dry, but very unpredictable and have little traction when wet regardless of wear.
Pirelli - Predictable but poor traction both in wet and dry, unpredictable and poor traction in wet/dry when worn.

With less rubber they would actually have better traction in the dry because they would not squirm as much. Having said that 3-4/32s is the new norm for replacing tires. Curious what the temperature was when you discovered this new found loss of traction. If below 55 degrees or so that would contribute to your loss of traction.

Thanks for the replies. Until about 3 months ago, I didn't have any traction problems. It is colder here, being winter, but still in the 50s or higher. It is 5/32 to 6/32 left, not 5/16 as I said. I really don't want to get summer-only tires because of the low mileage. The spinning is so bad that it's dangerous to stomp it-I have to back off immediately. My last timed 0-60 was 7.1 seconds(!). Any thoughts on the Michelin Pilot Sport A/S 3 tire?
Thanks again.

Those Pirelli PZero tires aren't good.

Hard to beat a Michelin tire.

perellis on this car suck man. Go with Nittos or if you want the best performance go Michelin Pilot Super Sports or the new PS4s.

Wait your P Zeros aren't summer? That's the problem, All season tires....

I was referring to summer tires. Here in AZ (Phoenix valley) that's all you need, except for maybe one week a year when it hits freezing. Nittos do very well even in colder weather (30-40's) in the morning a lot this past January. Just don't expose summer tires to freezing temps as it can cause cracking like dry rot due to freezing the compounds in the summer tires that give them their stickiness.

My car does the same thing if i want it to. Still does not compare to how crazy easy it was to lose the back end on my C6. Them hard run flats don't grip.

Just today I was thinking that my tires didn't seem as good as they used to be. I've got 17k and change on them. I'll be looking for some summer tires once they're done with.
