Need a permanent fix for winter tires that won't hold air every fall.
For the last 3-4 years, my winter tires (Nokian Hakkas) have slowly gone flat over the summer. Not a big deal. I fill them up and it's good go you'd think, right? No luck. After I fill them up, they'll hold air long enough to get to work and back again, but the next morning they need 10-15psi again. I'll often top them up again if I have to go anywhere in the evening, and they're down again by morning.
The last couple times I took them into a tire shop, they just popped the bead off and re-mounted them and they were good for the rest of the winter, so I don't think it's anything to do with the tires.
I've done it now for this winter and it's the last winter for the tires (I probably shouldn't be running them this winter, but I can't afford new ones and my other tires are full summers). Just wondering, what I can do over the summer to prevent this problem in the future.

"Understeer is when you hit the wall with the front of the car and oversteer is when you hit the wall with the rear of the car. Horsepower is how fast you hit the wall, torque is how far you take the wall with you."
