Not only do they rotate, but the "pickup" and huge globs of clag inside the wheel defeat the whole process.

Do your SC3Rs ever cord on the outside before the inside? Or do you simply have too much camber to cord the outsides first? Also do you drive on your SC3Rs to the track or are they a track only set of wheel/tires? I really want my front SC3Rs to last two full track days (or 8 sessions/heat cycles) before replacing them, I’ll be using SC3Rs on a dedicated set of track wheels for the first time this upcoming season on a corner heavy track.

I have -2.5 camber on the front of my ZL1 so I imagine mine will cord on the outside before the inside but obviously would like them to wear as evenly as possible to make them last as long as possible.

GMG - no lap time degradation in the dry with the tires flipped especially in the fact that they are (very) used when flipped.

GMG,
I have yet to cord a front SC3R on anything but the far inner edge (A common problem with the ZLE). Last "season" I ended up having two sets of fronts with me at all times and I would swap them out every 2 sessions. A pain, but it allowed me to get a solid 14-15 heat cycles out of a "set" before they cycled out. I trailer my car to and from, so not a huge deal having to bring spare wheels. If you are anywhere near an advanced level driver, you won't get the fronts to last two days on a typical event with 4-6 sessions.

16 HC’s - started to cord at 15 and I finished them (way) off the 16th HC and on the 92 mile drive home. Front is at -2.7 on SS 1LE.

My understanding was that the performance of these tires does not degrade over the course of their life / until they cord so I didn’t know if wear would play an issue or not.

I thought I recalled reading on this forum that drivers were cording the insides of these tires because they drove the car on the street as well as to and from the track but apparently that’s not the only reason, or the reason. It make me wonder how much of an impact camber level plays and if the reduced handling (with less camber) would be worth the potential increase in tire life span. I also seem to recall reading that some drivers were cording the outsides of these tires because they didn’t have enough negative camber, but maybe I’m getting that confused with the R7’s... Also to make sure I’m not missing something; Do you change your 2 sets of front tires every 2 sessions for any reason other than just to make sure they wear evenly at the similar rate? Or are you accomplishing something over and above the fact that just having 2 sets of front tires will mean you’ll get twice as many sessions compared to having 1 set (such as having more margin/buffer in case 1 set wears faster than the other)? I’m far from an advanced driver, just started last year, but my local track is very technical and I drive hard, I guess only time will tell how long they will last for me...

FYI - on the G3's and G3R's, they are very good down to the cords, but, performance does drop off between new and corded due to the heat cycling effect on the rubber. It's not night and day, but, it is noticeable the more consistent you get as a driver, with more data and time under your belt, you will be able to tell the degradation more.
I'm pretty sure the same can be said of most / all other performance tires. |

I'd almost wonder if there would be any further benefit by swapping them out every session (which would get really old in a hurry). Norm

I believe the reason ZLE's cord the inner edge of the tires is because of a dynamic toe change during braking and or cornering. I do not believe it is related to camber at all. At least, the cording that track guys are seeing.
R7's were the tires that need more camber and were cording the outer edge. I simply swap fronts out every few sessions so their wear will mimic that of the rears, thus allowing me to run the "set" at an even wear pattern for 14 odd heat cycles. That way I'm not starting with a fresh set of fronts with rears that already have 7 cycles. It also allows me to complete a full weekend without going to the tire store.
