Anyone know how to read tires?

Crushed 1LE · 07-26-2022, 03:23 PM

Brand new 3R's with 1 track day on them (7 sessions).
-3.5 front camber
-2.5 rear camber
Started at 26psi and then maintained 35/36 psi

Tires performed fantastic, but I'm concerned about what appears to be a lack of inside wear. The outside half is way more warn, especially on the rears where it looks like the inside is basically brand new.

More negative camber? Toe adjustments? Pressure to low/high. The track has lots of tight corners, with only 2 shorter straights.

Any comments or thoughts would be greatly appreciated.

why is your front camber different L to R?

Sorry. I actually posted the wrong picture. FL -3.5 & FR -3.2. Everything else is the same. Still not the same. I noticed that a bit after I picked the car up. Technician error I guess. It was not intentional, and they said they would take care of it. Don't know why he didn't notice it when doing the alignment. Maybe it moved when he tightened everything up and was having a bad day?

Normally these tires do wear faster on the outside due to the weight of the car and the amount of grip it has. I have talked to a few race mechanics and they said if you worry about tire wear start at 30-31psi and you will get a little more life out of the tires. You wont be as fast but you will get more sessions. At the end of the day lets face it, only a few of us can really get 100% out of this car so a couple more days at the track is better than winning HPDE

Do a corner balance on it if you really need it.

You should be counting your blessings that you dont have inside tire wear

That doesn’t look too bad…if you are worried about it or want more life u can always flipt the tires

If you want to get more scientific get a infrared temp guage and take tire temps in inside outside and center and see what they show
