You're right about decreasing torque. But you're wrong about losing speed.

A smaller tire buys you acceleration at the expense of speed. A larger tire trades acceleration for better speed.

So by using a larger tire, I would be a tad slower to get to 60mph but I can hit a higher V-max before I run out of engine revs.
