At least they aren't nearly as expensive as vta tires. For the price, I just replace mine after 4-5 race days. To the guys that give the facepalms and smart ass comments just for us bringing up tire problems, why even comment? Some of us are new to onroad racing and if we are doing something wrong, we'd like to get some actual advice from more experienced guys on what to do. It doesn't help being a pretentious f***wit. Just my honest opinion as a guy who only started on-road about a year ago, take it for what it's worth...
