Use some after-run oil on them , then wintergreen alcohol from the grocery store.
Your tires will have more than enough grip after that. Also good thing about after run oil. It takes like 30minutes to absorb and whatever residual is left can be cleaned off with the wintergreen alcohol.
Its the cheapest & easiest way to return grip to a rubber tire. Figuring everyone in nitro usually has a bottle of afterun oil. Rub it into the tire using paper towell or plastic bag (which wont absord as much oil).
Also Trinity tire tweak is good to try, but seemed to take about a full day to absorb into my tires. I coat the tire, place in a plastic zip lock bag and let them absorb.
