I have been racing a 1/8 mile backyard track lately and i am wanting some advice on tire choice as well as duro. running small block open. Some nights the track is soft to where when you walk on it the dirt under our feet feels spongy. and then there are times to where you cant get your fingernail in the track at all it gets so dry and hard. I have some yellow vega's as well as some burris tires. Any advice on when to run what tire and what duro i should shoot for on both track conditions. I work tires throughout the week so they have plenty of bite. just need some help with tire selection. Thanks!
