Street tires won't be the same after you track them.
 

(Characteristically)

Truth or False?

false

:confused:

They will be drag slicks!

lol you just lose tread faster than street driving, if you know what you are doing.

:iagree:

Though I will qualify with: it depends on how much track (I would think you could wear tires out completely in short order at the track). I happen to have precisely this experience this week, as I drove my Z at COTA last weekend. My Z is my DD and had never seen track previously. My Nitto Invos aren't any different other than maybe being about 2/32 less tread than before the track. Having been through more than one pair of these same tires, I can affirm that their performance has not been altered from what I would expect for their current tread depth. I should have gotten an alignment prior to the track, but I didn't (so it's been 3-4 months since my last one). I went ahead and got one on Wednesday and found everything to be fine except for my rear toe. The front was also barely within tolerance. No issues whatsoever (except that I need an oil cooler if I want to do any sort of sustained track event :icon17:)

It depends.

All depends on how you drive during your track time

False (for me).

I think it truly depends though. Track condition, road hazards and driving skill all come into play. Spend a lot of time on the curb/shoulder/edge and your gonna chew up the outsides, causing a different feel back on the regular road. After I took 1 run on the track in South Carolina however, my tires (characteristically) were the same.

That's for the fast guys. Blistering a tire.

Some say that once the tire compound been through track sessions, the tire compound changes resulting less grip on street.

Yay? Nay?

True for racing tires since they use softer compounds they "heat cycle" out in 5 to 50 heat cycles depending on the tire.

Not true for street compound tires even the sticky ones in my experience.

To elaborate more, I think the key question is whether tire compound changes/deteriorates if the tire is being heated past its operating temperature, to the point that the compound no longer grips the same way even after it has been cooled down.

I did 3 laps on my Prius, the LRR tires started chunking immediately.....

I can't tell any difference. I drove the car a lot faster in my 2nd track session than the 1st but the tires still feel good on the street daily driving. I credit the sway bars with allowing me to go faster (or feel confident enough to do so). I would assume I could do another 2 track sessions for a total of 4 track days before thinking about new tires but rememember my fast is a person who has done 2 track events only so I'm probably not stressing my tires all that much yet.
