Most bikes come with the cheapest possible tires and inner tubes. If you're going to ride a lot then it's worth buying something more robust, even if they're a bit heavier. Continental Gatorskin tires are pretty good, and you can also get puncture resistant tubes with thicker walls and internal liquid sealant.

It also helps to carry a CO2 inflator with a few cartridges. Much faster than a hand pump.

I have thousands and thousands of miles on my bicycle tires. The cheap tires on my commuting bike kept wearing out, and I eventually switched to a high-quality replacement with a high latex content. I haven't had to replace the tires since, and the visible wear is minimal. I cannot recommend good tires strongly enough.
