edited April 2011 in MTB general
I have two of the above on my bike, both bought at the same time. I only noticed today that they both have different max inflation pressures. One is 35-65 and the other is 35-80 psi........WHY ? Should they not be the same as the tyres are identicle apart from the pressures. ?

    I wouldn't worry about the pressure. They are the second worst tyres I have used. Only conti Mountain Kings are worse.

    Is one LK Control or LS Sport?

    They are actually OK if your use suits them. They roll really well and as long as it isnt sloppy have reasonable grip. My son had them for years on his Spesh Hotrock and they served him well. I am sure they are no good for serious offroad but mixed dry terrain, firetrack and road they are pretty good.

    There are a growing number now who swear by Fast Trak rear and Spesh Captain Control front - I am just trying it out as a fast combo for XC and it seems like a winning combination right now.
