Your new tires are 5.8 ounces heavier for each tire. I'm not sure the weight alone would be that noticeable on a steel framed 3 speed like that Gazelle.

Indeed it is rod drum brakes.

The front wheel spins 50 sec.
The rear wheel spins 30 sec.

Then, I notice the rear wheel is slightly rubbing the brake rod...just barely rubbing the sidewall. The old tire had alot of clearance here. This confirms that these new tires are indeed much wider.
