Been running Optima Red for about 3 years ... no issues
The only issue I ever had was when I first bought it.
They did not give me the red plastic base plate.
So it was hopping around a little for a few miles on my way back over to PepBoys. Walked in, told them what I needed and they handed me one.
Fit like a glove, has started perfect every day since... hot cold rain. It doesnt care.
Costco may still carry them, its not in the separate tire department, but inside the main store. I could have saved about $20-$25 if I knew where they were hiding them in the first place.
