asking how long tyres last is a f**king stupid question. cause everyones opinion of how long something should last varies, along with how much and how they ride, if you ride every night, and have to ride 4-5miles into town and then 4-5 miles back, they won't last as long, to many f**king variables BLAH the compound is softer than maxxis or echo's so they will wear faster. but f**k wear rate it's all about performance right there very gripy and have a good puncture resistance, they aren't the lightest of the mod tyres available but at a whopping 50grams more than the monty i wouldn't loose any sleep over it.
