If you bicycle regularly, understanding how to do so in the elements is vital. No matter where you live, it is likely that a rainy day or two will happen to you.
Riding a bike in the rain is different than doing so during fine weather. According to Map My Run, If you plan to bike in the rain, it is a good idea to lower your tire pressure.
Why does tire pressure matter?
In perfect circumstances, skinny wheels with high tire pressure and low tread are perfect for maintaining a lot of speed. However, if the ground is wet, this is a recipe for losing traction and falling off your bike. How much you will need to reduce the tire pressure depends on the variety of tire you have.
If you regularly ride in the rain, make sure that you have a bike wheel that is at least 25 mm or wider. When it rains, reduce the tire pressure between 80 and 90 PSI. This will give you more surface area on the road and better grip.
What else can I do to stay safe?
If you ride on the street, make sure that you avoid painted lines as much as possible. Painted lines on the street are more slippery than regular pavement. If you must ride across painted lines (like a crosswalk), do so perpendicularly.
In addition, keep your eyes open for any rainbow puddles you see on the ground. These are puddles that have oil in them, and you should avoid these. You are most likely to see them at the beginning of the rainy season or in light rains. Heavier rains will wash the oil away.
