You're still correct though. I'm 99% sure that the F1 A3 tire is labeled as outside and inside as well.

I don't remember offhand.. I think they have the winged feet showing the direction of travel, but I can't visualize the tire otherwise to that detail.

I'd have to look later, but yeah, an Asymmetric tire is sided and when mismatched front/rear, they're position fixed in both aspects regardless. So, we're all good.

if tires still grip well on a track and don't show cords they are still good to use.
BUT - if you drive to/from track on them and the tread is below the wear bars then their wet performance will be VERY suspect. Just keep this in mind and decide accordingly.

I wouldn't worry about flipping them on the rims to get every bit out of the expensive tires. The asymmetric design is to evacuate water in wet conditions. Unless you are running in the wet it shouldn't be a problem. The center part of the tire looks pretty good, like an R compound tire. Any one else have an opinion on flipping?

Better check with the tire mfr regarding the consequences of flipping. Sometimes the asymmetry is in the carcass structure. An 'inner and outer sidewalls not being the same or symmetrical' would be one possibility, which would handle differently if mounted "wrong". While something like that might well be manageable at autocross; it'd most likely be less so at 1.1g in a 100 mph kink.

I've even seen tires that looked like they were on the wrong side of the car based on the directional tread pattern pointing the "wrong" way, but which was correct per the sidewall information.

I followed the advice of some of you and went to see a specialty race tire shop.

They checked the construction of the tires and said there's no problems flipping them (steel belts etc.) . When I asked about the tire being asymmetric, they started laughing and said: did you look at your tires recently, maybe when they were new they had an asymmetric pattern.
Bottom line, they flipped the tires and I'm good to go for another weekend (so I hope...)

Interesting. I thought for sure these were labeled inside/outside. Good to know.

I took another look. I was wrong , there's an 'inside' marker.
Regardless the tire has the construction pattern written on it, which confirmed that both side walls are built the same. The tread pattern will not be kept flipped.
