Was it just a heavy tire or a heavy tire with lots of rolling resistance.
I've done both, too. And I haven't noticed heavy tires, but I have noticed larger rolling resistance is quite noticeable on hills. If you want to do an experiment, that's fine. Just make sure you're measuring what you think you're measuring (
i.e., difference in tire weights and not differences in tire composition/pressure).
