Rodney, not trying to be a killjoy, BUT...riding in a lightning storm is just asking for it. Bike tires as well as car tires provide zero protection from lightning strikes.

It's a common misconception that it's the car's tires that protect you from lightning strikes. The reality of it is it's the metal body of a car. Lightning is high frequency electricity and it tends to travel along the surface of a metallic object, not through it, to ground. AKA "The skin effect." Since you don't have a metal covered body, a lighting strike while riding a bike will most likely kill you.

Many years ago, I was driving a car in a bad storm. The top of the car ended up taking a strike. The strike went along the body and through the tires to ground. The paint on the roof was badly burnt and blistered, the metal had burns and was galled, and I had 4 flat tires as the rubber melted. Had it been my Miata, I most likely wouldn't be posting here today as it has a canvas top.

You could also think of it like this, the lightning bolt just cleared a 5 mile spark gap. That amount of power is truely unimaginable. What possible defense could a 16" car tire provide, yet alone a bike tire.

Car tires do provide some degree of protection from downed power lines. This is because the voltage is many orders of magnitude lower and it doesn't exceed the break down voltage of a rubber tire. If a line lands on your car, don't get out of it.

Be safe, seek immediate shelter in a lightning storm.
