I'm a clyde, down from 265 in January to ~225-230 now.
And I keep falling down. I never went down a single time in 2000 miles on my old hybrid, and now I've been down 3 times in the last 1000 miles on my road bike.

Your road bike might require more precise control of your CG than your hybrid did. That is, the hybrid might be more tolerant of "sloppy" technique than the road bike. You might need to be less abrupt in your movements.

The center of gravity will be in a different location on a hybrid than on a road bicycle. Also, since the OP is a clyde who is in the process of losing weight, his centre of gravity may be changing somewhat which could be affecting balance. Put the two situations together ... and it could be a double whammy of balance issues.
pbd, my suggestion would be to work on balance as you're losing weight. Maybe take some yoga classes that put you into balance poses.
If you haven't already, I'd suggest checking your bicycle fit. Go through some of the online fitting advice or go to the shop where you got the bicycle and have them set you up on the trainer and do a fitting.
Also, it might be an idea to go to a quiet parking lot and ride around practicing cornering at very slow speeds first, and then gradually increasing your speed as you get used to your new center of gravity on the bicycle and your own new center of gravity.
And yes, go for the wider tires. You don't ever need to feel bad about replacing Michelins (bleck!) ... but in general you don't need to feel bad about replacing new tires because you're not throwing them out, you're just hanging them in your garage for future use.
