My friends aren't helpful. They're just bullies. I have a solstice with two sets of wheels. One set is 265/35/18 a052s. The other is 255/35/18 660/re71rs. I corded a little bit of one of the yoks by overheating it last autox. Currently I've only got like 10ish events left, but two are track events and the one is a road rally with track driving (Mid Alantic Car Fest, check it out). The 255 set is probably not gonna last the year and my plan was use that for local autox and save the yoks for the track stuff. But I was told don't get one new yok, so should I get two? Should I just suck it up? Or send it?
I once corded a tire at an event, so I called a tire engineer friend. Um, that tire is done, he insisted.
how much life is left on the other tires? If the one is corded, I'd imagine the other isn't far behind (i'm assuming your car has ABS and other tech that prevents flat spotting, etc.)
Are the other 2 okay? Is there a reason you have 2 sets of 200tw tires? Perhaps now is a good time to get one set of ECS Sport02 and use them as every day / rain tires.
In reply to ClearWaterMS :
I won't race in the rain. But I was using one for track and one for autox. All 3 other yoks are totally fine.
I would buy a new set to replace the yoks. Use them for track and the car fest event. Use up the other set for your Autox events until they are bad then make sure you store the new set good for the winter.
Unless it's a financial thing just buy next seasons tires today. They won't be appreciably worse after 6 months then they would be brand new and your set of yoks are no longer a useable set.
You could replace two yoks but then you will forever have this weird heat cycle delta on your tires because the old yoks will wear out before the new ones and then you will buy 2 more and continue it forever.
If you care at all about your results or even developing your driving skill, you want a matched set of tires all the same age/heat cycles. Replacing one or even two will produce a car with strange handling characteristics that you'll have to drive around; resulting in slower times, frustrating handling, and potentially learning bad habits in your driving.
If you're just autoxing for fun and not concerned about finishing position, I'd suggest you're better off with a matched set of less expensive (but slower) tires than a mismatched set of nominally faster ones.
I don't think anyone is going to tell you it is ok to drive around on corded tires, especially in any sort of racing.
Will tech inspection even allow that?
Years ago I had a front corner that got knocked out of alignment and it corded a tire in about 15 laps. The rest of the tires were about 80 percent. I had a event scheduled for the next weekend. I ordered another tire from TireRack shaved to match the other tires and had them heat cycle it for me. Was it better than a complete new set? No but more than good enough for what we were doing with the car. The car was an endurance car not a time trial / sprint race car so it was more than good enough. In fact non of the other drivers even noticed.
Oh and I am sure you know this but get your alignment checked.

I've stuffed one new tire on a corner. It's not optimal but it also wasn't horrendous.

We use to do that all the time. When you are running out of tires in a 24 hour race due to track induced alignments you get to the point where if it is round and black you send it.

Couldn't you turn it inside out like a dirty shirt?
Tires come with rubber on both sides of the cords and we only use one side of that, seems wasteful doesn't it?

OMG.... a poor SAAB hit a wall early on at one Lemons race. They got back on track a few hours later but the radiator was pretty unprotected and held in with zipties, the turbo was connected directly to the intake manifold because the intercooler was now a modern art installation, and the right front tire had an alarming amount of positive camber, with a counterclockwise course. They went through RF tires at a phenomenal rate and were doing just as you say: anything that held air and still had something treadlike got cycled through to that corner.
