If you don’t have winter weather during the winter season, then you can drive with summer tires all year around. Summer tires are designed for warm temperatures, so for above freezing and for summer conditions, such as sun and rain. If your summer is limited to these conditions, then you can drive with summer tires all year around.
If you face winter conditions, such as snow, ice and slush then the answer is no. If the temperatures are very cold, below 32°F, then the answer is also no. In these cases you would need winter tires.
