The wife's '93 S10 Blazer has the aluminum rims. The tires have been on it for a few years but she puts so few miles on that they are still really good. One tire leaks very slowly, so I'm putting air in it every couple of weeks. Today I took it off and stuck it in a wheelbarrow full of water and I see that the leak is around the inner bead. I have never tried the "fix-a-flat" stuff in the spray can. I was wondering if I can expect that to seal it. If I have to take it off the rim, I'll probably just buy new tires for the Blazer and put these on another truck that gets a lot more use. (I really don't want off-road treads on my 2wd Suburban, but I hate to just toss these tires. A few more years and I'll be afraid to run them anyway, no matter how good they look.)

You need your head, your brains are in it.
