Old vs new tires

How can an older set of tires best be utilized? By old I mean older date code tires that have been ran and heat cycled and prepped a lot. New to the sport and have more older sets of tires than new sets, so just trying to get an idea for when one may work better than the other or how one should be treated compared to the other (prep and duro wise).

When people talk old verses new, its really meant as fresh rolled verses older, 1,2,3,4,5 month rolled, not as older with date code. You will want a tire made within that year, usually.
Take a set fresh rolled, this week. Take a set rolled a month ago, a set from 2 months ago, etc. Some will do every 2 weeks, instead of a month.

Not if it's Burris tires

Burris 33a. Local racing. only wiping outside prep. Just thought maybe there would be a way whether it be with chemicals or a certain duro that you can get speed out of an older tire. Of course given that you draw the line somewhere between old and junk lol
 
Burris is a whole other deal than Maxxis on tires.

Very often, an older date code Burris will be faster than new tires.
Typically they are not ones that have been prepped hard over and over though.
It's the ones that have been cured out and hardened up that work best when the tracks get hard, bite up, and are fast.
Consider the spring rate of the sidewalls when comparing 33As specifically. An older tire (that's not been prepped and raced a lot) will have a stiffer sidewall than a brand new tire. That gives a real advantage on bigger momentum tracks where roll speed is msot important.
If it's been something that's been wiped hard previously, then I'd just relegate that set to when the track takes a harshly prepped tire.

Older ones will be faster, for a track that has some bite, and as long as you didnt over prep them.
Lots take a set of Burris, older, and wipe 1-2 times with goat, Krug, and go out. Once they come off track, you have to take those off and set them back in the trailer for a while, grab another set and do it again.
Softer and/or wet tracks, not the same. You can wipe more and the age of tire isnt quite as important.
