I have a squared wheel/tire setup and hope to document when and how I use each tire.

I used this paint marker advertised as "high temperature" and "highly permanent" to mark each tire on the inside walls, but the markings were 90% worn after one track day.

Does anyone know of a more permanent solution?

These, specifically the Yellow one. I forgot where I was finding them individually.

I'm writing on the outside walls of the tire, but typically just "run count" or sometimes location info.

What problem are you trying to solve?

I gave up on marking the tires and ended up creating two tools to keep track of the tire wear and position:

- I download the track time and session data off my Racelogic VBOX and put it into an Excel spreadsheet with a tab for every pair of tires I use. I keep track of the tires by their type, manufacturer, size and date code. From that I know how many heat-cycles are left on each tire individually, even though I manage them in pairs.
- When I take a set of tires off the car, I mark the corner that each one was used on by scribbling it with a fingertip in the brake dust inside the rim. Crude but effective.

Those two tools are all I need to know which tires to run on each axle - front or rear - for an upcoming event. As for which side to put them on, I just put the tire with the most remaining rubber (out of each pair) on the side that'll take the most wear on my next track event.

The way this plays out is that, if I'm going to an anti-clockwise track where you turn left more than right, the pair of tires with the fewest heat cycles goes on the front, and the tire out of each pair with the most rubber goes on the right side => job done!

I just use a paint marker from Walmart, if I'm handling more than 1 car, I use a different color marker for each car. Tires that I use really don't last long enough to use a spreadsheet.

My dogs mark them for me. HA! Sorry had to


But I use paint pens I get off Amazon. Buy them in packs of 10

Kinda what I was thinking.

If you're doing AutoX, then you can do hash-marks per run. If you're running HPDE or testing, then write down the number of minutes running with a circle around it on the sidewall. Log the total number at the end of the day.

I use this paint pen from Amazon. It has never come off, but maybe I am not fast enough!


I rotate tires LF to RR and RF to LR. After a track day, I mark the tire with the position and heat cycles. So the tire gets a LF/RR, then LF4, RR3 etc left to right around the outside of the tire. Typically after 3 days or 12 cycles running timed sessions, the tires get pancaked and become practice tires, usually chording on the 3rd practice day.

Not trying to make up the 6 seconds to the guys at the front of the pack, but loving every minute of trying!

I follow the Blacksheep method or just watch where the tire lays over . Often, for me, simply sight studying each run is a way to focus on if my tire temps are working. A weekend may start with markings at a track and if things are working I keep things static most of the weekend -- changing if the weather does.
