Yeah i didnt know if like now how its cold ya check em at room temp,and say if ya get em 97 degrees on 20 laps ya could use hotbox to see which set stays more consistent or which set gets softer at a given temp.it was a thought because ive grinded tires and had em turn bubble gum and some not and hit em with about the same amount of effort.No.
I try to keep everything standard when it comes to checking duro -- if I check one set @ 70*, I want to compare it to other sets checked at the same temps.
Just be aware that as the temp goes up (operating temp or ambient temp) the rubber gets softer and the duro drops.
Use that info to your advantage.
Just be consistent in how you check your duro -- if it's 90* out on race day, then check all of your tires at that temp (AND with them out of direct sun.)

Bubble gum is the prep you are using, have never seen that big of a swing unless it was intentionalYeah i didnt know if like now how its cold ya check em at room temp,and say if ya get em 97 degrees on 20 laps ya could use hotbox to see which set stays more consistent or which set gets softer at a given temp.it was a thought because ive grinded tires and had em turn bubble gum and some not and hit em with about the same amount of effort.
If it's cold - check them all cold. The durometer number is simply a comparison number (kind of like a dyno give comparisons in torque and HP for one engine to another.) i just write in my notes what the ambient temp was when the tires were checked.Yeah i didnt know if like now how its cold ya check em at room temp,and say if ya get em 97 degrees on 20 laps ya could use hotbox to see which set stays more consistent or which set gets softer at a given temp.it was a thought because ive grinded tires and had em turn bubble gum and some not and hit em with about the same amount of effort.
