Look at the price of tubes. Then look at the price of new front tires. Then look at the hassle of installing the tube vs new tires... I'd just put new tires on and be done with it.

Let me correct myself.... First, where are they leaking from? Is it from something piercing the tire, cracks in the sidewall from age, or around the tire bead? I had a tire that leaked because the valve stem cracked.
