Hey friends. Just bought an addmotor 560 p7. The thing is a beast. However at 150 miles I got a flat tire. I got a replacement coming. My question is other than buying puncture resistant tires. Which I cant afford right now. What can I do to prevent this. Ive seen tire slime and tire liners. I worry the slime will settle and make a rough ride until it speads back out. I dont know what to think about the liners. If anyone can help with this it would be appreciated. Thanks.
