No, as others have said this is not advisable. But what you can do is rotate the front tyre to the back and put a fresh one on the front. That way you only need one new tyre.

At my last job I was asked to get a certain cert as one of my yearly goals. When I asked for time to study, I was told to do it on my own time. I said “If you want me to do this on my own time, clearly it is optional and I’m not doing it.” and then I didn’t.

In my case there was no raise to be had from doing it though, so it was easier to refuse. Good luck!
