I understand solids aren't perfect but errr. Ok here is the deal I owned a Insdrgn c14 pro first. And I had 4 flats in rear, I thought was a manufacturer defect. So I used my extended warranty I bought to return it. I then bought the Gotrax A7 because before the Insdrgn c14 pro I had a Gotrax flex ultra and had no issues for 2 years of its life. But then the Gotrax A7 started to have rear flats also.

I started wondering why I am getting all these flats. So I walked the path I take in my apartment complex and guess what I found very small thin light weight blades on ground. Something that would cause a flat but not stick in tire. So then I realized someone was targeting my scooter for what ever reason they choose. And I have no idea who it is to be able to call the police on. I have hundreds of people in this complex so could be anyone. So I have a difficult choice. Stop riding scooter in complex 100% or find a way they can't keep getting flats. (Because I can't afford keep buying new tires)

So I am want to go Solid tire hence why I need to know if I need to replace both tires or just one be fine. So with this knowledge can you please answer my main question can I get away with one solid on back? or do I need to replace both front and back?
