I got a set of Blizzak LM-22's on ASA KA3's. When I put them on the car, one was flat (bad sensor). Then a week later another was leaking at the rim sensor connection. I think it was because it got down into the low 20' and maybe the metal was contracting a bit. So far tire rack has not called back with a solution. Now I'm worried when it gets cold if I will go out to the car and have flats. Anyone else with this problem? It really sucks.

 

mine leaked and I had to keep going back to the tire shop I used and they would teak with them and fix it

if they are put on right they wont leak

 

Also, make sure you don't over tighten or under tighten the wheel sensor nut. Too much and you'll rip the rubber gasket, too little and you'll have leaks.

Also, make sure they are tightened to 65-87 ft lbs as per the TSB here:
