Pros and cons.....

You can do what you want; but remember, the designers of the TT and TV build their product to perform around the materials they have selected. That includes the tires.

Marginal or not those are the materials that were selected to do the job.

Of course if you are the expert and are compelled to up-grade there is nothing stopping you, except perhaps the manufacturers warrantee.

Almost everyone upgrades a few TT or TV items; because it just makes them feel safer, better, etc.

I always figured they put that size tire on for a reason.

Yep, and the reason is that smaller is cheaper.
