Was at an hpde event and had to cut the day short following a post session inspection revealed both rears had separation starting across the tread as well as the driver rear showing separation along 1/4 of the circumference of the sidewall.

Tires are less than 2 months old, was the second track day. I had rotated the tires following the first track day. I had wear partially down sidewall from first day due to a non aggressive alignment / too low tire pressure.

Today was 2 deg C, track is 5km long, made a warm up out lap before pushing each session.

Curious if I caused the issues or if there's something wrong with my tires. If I caused it, what should I do to prevent it?

What's the date code on those tires?

 

2517 (Late June 2017)

I checked the fender and there's no signs of rubbing. Put about 200 miles on them before the first track day.

 

Definitely take them back for refund or replacement.

 

Just wanted to follow up, the tire condition was self induced. Combination of insufficient camber and wheel rotation instead of dismount and remount. Combined with the weight of the car, the aggressive driving, stock suspension and abrasive track surface, I allowed the wear to exceed the tread block and wore through to the underlay of the tire.

Corrections include dialing in more camber, adjusting pressures and refining my technique

 

Wow. Most people would NEVER admit fault for something like this. Kudos for being honest.

 

Other than the above issues, how did you like the tires? I bought the same ones with a couple track days in mind.

 

First summer tracking the car. Did somewhere between 15-20 20 min sessions. Got moved up to the advanced group 3/4 of the way through. I am inexperienced with car setup beyond general basics. (So you can decide how relevant my input is)

Tires have good grip on the street and decent in the wet. On track they are very progressive during dry breakaway and still somewhat so in the wet. They heat up rather quickly and turn somewhat greasy after 12-15min. This is where I having issues as I kept pushing them rather then allowing them to cool.

As mentioned I dialed in alignment specs, but the tires were already pretty well used. I never got into dialing in pressures but will be experimenting this season on a fresh set with a pyro.

For stock sizes the only other tire would be a nitto nt01. I plan to stick with the bfgs for now. I want to refine my driving to get the most out of these tires before I step up to a semislick. I also feel suspension mods would be required along with getting the torque arm off my t5 to ensure no reliability issues.

Personally I had lots of fun at the track. I know there is much room to improve the car as well as the driver. My last outing was a near freezing rainy day at Mosport. Was an excellent learning experience on controlling the rate of weight transfer and balancing the inputs to get the most out of the available grip. Seems like mastering those skills will pay dividends when I eventually begin work on refining the handling of the car
