I must be the exception to the rule. Got 30k out of my PS2s and I currently have Vreds on 20s that have 29k on them. Looks like they got at least another 5k miles on them but I'll probably change them soon because noise is becoming an issue. With the PS2s, the front and back wear was pretty close but with the Vreds I notice the back wearing a bit faster than the front.
