Which dungeon are we talking, here? I try to keep up a brisk pace without necessarily chain pulling because in lower level dungeons there may be TP issues.

It's annoying but as a tank, if I saw you running ahead to pull mobs, I'd just go take them off you. Then I'd ask the healer if they're okay with big pulls, then I'd pull everything I can. But depending on what level, there are certain dungeons that's not reasonable because I don't have the right cooldowns (level syncing) and the healer lacks sustained healing power, also due to level syncing. So what may seem stress free to you is actually an intense encounter for the healer and tank because the tank may have to work hard for group aggro and the healer becomes a healbot, spamming cure for the tank to survive.

Consider their perspective. And communication goes a long way. Ask for the biggest pulls the tank and healer feel comfortable with. There are some dungeons it can't be done (mobs tethered, mobs hit too hard, no good cooldowns). There are others it will work for.
