Wheels and tires dilemma, Accord V6 EX-L?

I recently purchased a '10 Honda Accord EX-L V6 Manual. Winter is quickly approaching and i want to know my best options, being that the winter here in Pittsburgh last year was a total nightmare.

the car came with 19" wheels, meaning the tires are 245/40-19. Tires for them are quite pricey (http://www.tirerack.com/tires/TireSearchResults.jsp?autoYear=2010&autoMake=Honda&autoModel=Accord+Coupe&autoModClar=EX-L+V6&sortCode=57375&width=245%2F&ratio=40&diameter=19&minSpeedRating=H) but i feel i can manage to afford them. The problem lies with winter. Would it be worth putting out the extra money for 17" steel wheels and mounting snow tires on them, or would this car do fine with 19" wheels and all-seasons?

i've never had a manual transmission with this much torque, nor have i had a car with 19" wheels, so i'm a bit paranoid about it. With the way this car whips around, i could easily see it being problematic if not driven carefully.

Winter is "quickly approaching"?

Its June.

Winter tires do not even go on sale until October and winter tires on their own wheels are ALWAYS infinitely better than any so-called all-season tire.

First off that is not the correct size tires for this car and it did not come with 19 inch wheels. The correct size is 225/50-17. Look in your owners manual and on the drivers door post and you will see that someone has installed aftermarket wheels/tires. The tires on the car now are 3.21% smaller in overall diameter than the OEM tires. Your speedometer is reading 2 mph slow. This is adversely effecting your fuel mileage. Know that a 225/45-19 will work perfectly with the set of tires you now have if that will save you any money. You can go to a auto salvage yard and purchase a set of 17 inch OEM wheels off any Honda and then buy a set of 225/50-17 snow tires and mount them on those wheels to use in the winter on the front of the car. This is acceptable and the 19" will be fine on the rear. Or you can sell these 19" tires and wheels and buy a set of 17" wheels like the ones that came on the car with the correct size tires.
