You could order new ones shaved to 'TRY' and match tread depth.

 

The 2 other tires are pretty damn close to being brand new, so I think it will be fine with 2 new tires.

Do you see any problem doing this?

 

Replace them sir!

 

If the 2 other tires are relatively new and theyre good, just replace the damaged ones. Also, id run the new tires on the front. Btw, thats happened to me before, but on the street. I had a different car at the time. Hit a pothole and the result was a pretty big bubble on my sidewall.

 

bubbles cause blowouts

 

My two new NT01's came in.

Should I run the brand new ones up front or out back?

 

I'd start with them in the back. If the old ones are heat cycled out then you don't want them in the rear.

 

Any particular reason?

This is not a DD and the car doesn't see the road, so I don't have to worry about hydroplaning if that is the reason.

Thanks!

 

The Evo is a front heavy car. New tires typically go in the front because the fronts will be used the most. Getting more detailed makes this more of a preference/setup topic that id rather not get into because there is too much to discuss. Loosely speaking, if your rear tires are in better condition your car will push, wont rotate as well, and so forth. If your 2 other tires are actually heat cycled out you should have just bought 4 new tires. Just because tires have plenty of tread doesnt mean theyre still good. Tread depth doesnt mean squat if the tire is heat cycled out. You can have relatively new tires with practically full tread that are hard, which means theyre useless.

In case you have a follow up question on tires. Try to mostly run on good tires. If you routinely run on tires that are heat cycled out your feedback/data is going to be based on those tires. So your progress/adjustments/setup will be pretty much useless because when you run good tires everything will be different.

 

Thanks for the info!

I'll see how the rear (older) tires perform at CTD and I will go from there. If they are indeed heat cycled out, it will cause a lot of oversteer, right? Since they will be on the rear and would be harder.

If that's the case, I will replace the other two as well.

Youre welcome. The issue here is experience, if you dont have enough you may not know the difference, let alone what to do. And based on your questions it doesnt sound like you have much, so i suggest you hook up with an instructor. Take it one step at a time and youll be fine.

 

CTD will be my first time on a "big" track. I have experience autocrossing, and go-karting. I'm super stoked to get out on the track, have a blast, and pick my instructors mind to bits!

Appreciate the welcoming responses!

 

Always put the fresher tires in the rear. I tried putting the better ones in the front before and all that happens is the front bites in for the turn and the rear snaps around on you.

I spun out twice in a row when I put the new tires in the front and old ones in the rear.

 

This is why some topics can go in circles because you have people with different types/levels of experience, different setups, and different driving styles trying to give feedback. I dont mean this in a bad way, but if you spun twice in a row maybe you caused it because you couldnt adapt. If the tires were the issue and you ran your bad ones in the front maybe your car would have pushed, or maybe it would have struggled to slow down under braking and you would have driven off track. If your tires are that bad and you dont have the experience to adapt, maybe its better to not use them. Otherwise, loosely speaking, you might spin because your front end has more grip or you might end up pushing in a corner because your car wont rotate or slow down enough causing you to drive off track. Btw, you can still spin with bad tires on the front. Your setup matters but so does the driver. It doesnt mean youre bad though. If you have that experience or have a good foundation its more likely youll adapt when you face those challenges.
