The answer is, "Yes."
BTW, it would help if we knew exactly which model you're getting and what your normal number of daily miles driven was.
Seriously, you will get every opinion under the sun here. It's a personal evaluation, at best. You have to balance your budget with how fast a charge you want to have. I consider your current circuit borderline. It will likely recharge your car fully overnight on a usual basis, but if you really run it down or have a short night, it might not. Which means that you couldn't do two back to back days of max miles without some extra charging somewhere. That might be entirely fine depending on your situation.
If you wanted to go with a 40a or 50a circuit, I'm confident that you would always be able to charge overnight. If you got an SR, it will also charge the car as fast as it's capable, an LR can use up to a 60a circuit. Unless you think you're buying another electric car and want to plan a charging situation for the future, I see little reason to put in a circuit larger than the car can use.
