Ozone exposure is a known source for tire or rubber degradation - outdoors or in a storage area near electrical motors (heat pumps, HVAC, oil furnaces, freezers/fridge). Most likely source is cold weather, driven or not, below freezing. Age of tire is its mfg. date not the date the vehicle is...

Driving on PS4's in colder temperatures is a challenge for the tires, handling, and safety; keep it parked or invest in better "weather" tires.

Are you on PS4's? If so a damaged tire/wheel is more likely than a flat spot. How low were the pressures and at what temp were they at when checked/adjusted?

As this started in early November (with cold temperatures(?)); it's more likely the tires were underinflated causing vibrations, or you've thrown a wheel weight, than a cold tire flat-spotting issue. Make sure pressures are correct and if vibrations continue have the tire(s) re-balanced before...

How long have the tires been on this vehicle? If well before the issue with vibration started and no unusual wear patterns have occurred then a damaged tire or thrown wheel weight are the most likely issue. As suggested, try moving fronts to rear and see if vibration changes.

Are you on the OEM wheels or aftermarket? At least one poster has had "clicking" issues with NSX wheels.

London, England (where minus is below 32 F rarely) or London, Ontario (where it's often below 0 F)? You'll destroy PS4s if driven cold below 20 F; otherwise you'll just wreck the vehicle or kill yourself - none are good outcomes.

A heated garage (above 20 F) implies the snow/salt mix will melt = salt water

Was the battery charger still operating when you got back from vacation? Any chance there was a power surge or lightening strike while you were gone? If you had "no issues" prior to this it's likely something was fried.

A heated garage, with a snow & salt accumulation on your vehicle, is not your friend! Best to leave the vehicle outside or, if you can, turn the heat off in the garage.

How many qts of replacement oil was needed - believe the newer filters only hold 1 - 2 cups?

FWIW - Honda cautions against using DOT 5 "Brake fluid marked DOT 5 is not compatible with your vehicle's braking system and can cause extensive damage." May or may not have to deal with sharing a common reservoir with the clutch system

...after installing a set of proper winter/all-season tires!

OCD - it's fine.
