annual snowfall inches:
snow on the ground:
the two above maps may seem redundant but they’re not.
inches of snow is mainly a measure of how much moisture is in the air in winter.
days with snow on the ground is mainly a measure of whether it is warm enough for the snow to melt.
map below was created by government to assess resources required to clear the roads of snow and ice …
here are some charts to help you understand what tires are best suited for which weather conditions:
and here is a more detailed explanation:
and here is the only map i found that attempts to show which area is best served by which type of tire:
personally i think the above map is overly cautious. i drove rear wheel drive BMW with summer tires in a snow storm in connecticut and was fine ( didn’t die )
however if you move to New Hampshire you will definitely want to swap to winter tires in winter
and if you’re in NYC / NJ area ( like where i have been living mostly ) you should really be using all-season tires, but most sports cars here come with Summer tires and i am too lazy to swap them to winters in winter …
in Florida, California and Houston using anything other than Summer tires would be idiotic
in Atlanta, Charlotte or Raleigh-Durham-Cary research triangle it seems a toss up between summer tires all year or all-seasons depending on whether your priority is peak performance in good road conditions or more predictable performance in all conditions.
NHTSA map of deadly car accidents caused by winter weather conditions
not sure why so few fatal crashes in Massachusetts - maybe because of high IQs or high incomes ( expensive cars )
Texas has bipolar weather - mostly scorching hot but then it occasionally just freezes. Probably everyone in Texas has summer tires and nobody knows how to drive in the snow so when it snows they all die.
fatalities in Alabama probably because it’s all retarded Niggers there.
on somewhat of a tangent engine wear increases exponentially during cold starts
ideally you would never want to start your engine at temperatures below 40F or so
which also lines up perfectly with operating temperature range of summer tires
in other words if you live in a climate zone that needs tires other than summer tires you’re going to be putting extra wear on the engine until it warms up
of course combustion engines may not have a lot of life left in them anyway ( getting replaced by electric cars )
speaking of Lithium batteries here is the temperature range for them
so about 60 to 90 degrees F is where you want to be with Lithium Batteries
i can confirm here in NJ the performance of my PHEV battery goes to shit in winter
in theory if cars were intelligently designed they would maintain battery temperature in optimum range just as your human body maintains optimum temperature
but cars are mostly reverse engineered from consumer demand and consumers just want flashy zoom zoom - they are too dumb to ask even for door handles that can be opened in an emergency let alone for intelligent thermal management
anyway neither tires, engines or batteries really like to see temperatures below freezing is the main point here.
the 90F in Florida summer is not really an issue. the problem is it can get a lot hotter than that in the sun. with shade and ventilation Florida summer is fine. but in direct sun and / or without ventilation it is a problem.
i also noticed pavement in Florida is noisier because they seem to use a different asphalt mix to better resist the heat. this is actually what i hated the most about Florida - the tire noise from roads there. as an Audiophile who always wears earplugs to protect my hearing i was ANGRY AND FRUSTRATED by how much noise was coming from the tires in Florida.
