Foods with a pH higher than 4.6 can harbor botulism bacteria spores; tomatoes are generally right around 4.5, so you're playing with fire if you do not bring the acid level up. Moreover, if you add anything to your tomatoes, such as onions, garlic or basil, you are lowering the acidity further.

My grandmother did ALL her canning using the water bath method on a wood-
burning stove. Never, ever a bad jar, and no one ever got sick. My mother did
all her canning using a large Burpee pressure canner/cooker on a gas stove.
