Both of those being decent street tires, and not "uber" street tires, they will probably be about the same on the track. You'll find that track miles aren't nearly as hard on tires as autocross miles are because most tracks have a lot of straights and very few "tight" turns. Small tread blocks, if you have them, will tend to "feather" from the high-speed sweepers, but most of that will correct itself before you finish the drive home.

I guess if you're not doing anything else with the RE040's and they're mounted and ready. Those would be the ones to bring. They'll be good enough for casual track use. Save your "better" tires for actual competition.
