Mr. 2D you’ve got lots of wear left on those tires. Walking is great and you don’t even have to do it all in the mall. I don’t know where you live but wherever it is, outside is good too; you can listen to music or a talk while you walk and you’ll really be enjoying yourself. It’s easily within reach.
I’m in Biloxi, Mississippi. It was about 100 degrees with high humidity today. I really have to walk inside the air-conditioned mall.
