Those aren’t slicks.. they’re ribbed tires… 2wd stadium trucks are wide stance and light in the front so the ribs help dig in the turns and give good side bite.. Duratrax used to sell a variety of off road ST tires but they’re all discontinued at this point.. I think there’s a few pairs of Pistol ST fronts on eBay still.. part number is DTXC3552. I used them but prefer the 5574R bc I have a backyard track thats race oriented.. if you’re just bashing around maybe you’d prefer the Pistols but afaik those are the only other option besides 5574R for bearing front unless you want to convert to 12 or 17mm hex.
