I must have a defective tire as my passenger front has corded entirely around the circumference (inside shoulder) while all other tires are still in great shape.

For the time being, I'll assume the tire (Nitto NT01) was defective. All other tires including the drivers front is in great shape with 6 track day/20 heat cycles (about 1/2 life for me) I've also run a previous set to the cords with this suspension setup so I don't think it's the setup (unless something has moved). All suspension fasteners are tight.

I'd prefer to save my $ and buy 1 tire to replace the worn/defective tire rather than a new pair. I can rotate these front from side to side as needed.

Any reason not to buy a 1 for 1 replacement? This is a dedicated track tire for my 996.

Thanks

Replace pairs unless the pair is almost brand new and you hit a nail or something on your spanky new tires.

But one tire corded on the edge does not sound Like a tire defect. I'd check your alignment and possibly links that kind of asynchronous wear is unusual unless you had spent the afternoon doing donuts in the super market parking lot. In which case you know who to blame

I would do a root cause analysis and have your alignment checked first. My data has shown that the inside edge of the most unloaded front tire (right side for clockwise tracks) usually experiences the highest tire temps. Maybe you were running too much camber on that wheel.

Can't help you with the tire replacement. Personally, I would buy two new ones and keep the old tire as a spare.

Ok, Thanks. Yes, I was hoping to get out on the cheap but realize it's a safety issue so I ordered a matching new pair. I'll get the car in the air to check it out.

I did replace the NT01s with RE-11's I use as rain tires on Sunday @ VIR and the wear on the front pass. looks good after 4 sessions.

Try to check tire temperatures across the tire if you can.

I would save the undamaged tire as a spare for when this happens to you again.

Definitely check the alignment before mounting the new tires!

To add anther data point...My passenger side tire experienced inside edge wear at the Glen (after 7 hour DE). I attributed this to cambered turns. The bulb at Lightning also eats inside of the inside tires. And I was running less than 2 degrees of camber.

Might want to swap side to side more frequently if running on one track.

I agree that alightment should be checked.
