Are you using an IR gun and do you have data from the old tires?One possible negative for these is they run hot. I think they might heat cycle out before they wear out.
Time will tell.
I can get temps from these but I do not have any data from the old tires. I only thought to put my hand on them because I smelled rubber like a race tire after some laps. I could easily hold my hand on them, so could a kid. But they are really warm.Are you using an IR gun and do you have data from the old tires?
