Will the 225/40/19 fit the Brembo wheels?
Question for those running Blizzaks 25's on their brembo wheels. Will the 225/40/19 fit the 9" wheels without any issues? I dont want it to overstretch where I cant even drive above 75mph.

According to the Tire Specs on Tire Rack for the Blizzak's, the 225/40/19 will fit from a 7.5-9" rim, so you can safely install those on Brembo wheels. I don't know that you will like the ride, being 1" shorter than the factory 255/40/19 tire, but if you already have a set and are trying to save money, or if you found a smoking deal on a set of the 225 size, you are good.
If I were you, I would get the 245/45/19 Blizzak. They are slightly taller than stock, +0.6", slightly narrower, -10mm, and cheaper, -$33 per tire, than the 255/40/19 factory equipped tire size.

Well its a bad idea to go down in size if for no other reason than it affects the load rating on your car. The replacement tires need to meet or exceed the load rating for current tires and this ignores the cumulative effect that going to a shorter and narrower snow tire will have on handling and braking since the contact patch will be smaller.
Ordinarily going from a wider tire to a narrower tire of the same diamter will change the bias of the contact patch giving it a more longitudal foot print, going to a narrower tire that is shorter in diameter reduces the contact patch overall, well at least in a dynamic state.
Now for the snarky part in what is probably a very rare scenario ...
Keep the bill handy in glovebox in the off (heaven forbid) chance you get in an accident due to loss of control or a tire failure. Your lawyer (payday) and the lawyer of anybody else(payday) involved in the accident will certainly be interested in who mounted and installed these tires on your vehicle.
You could certainly take the wheels off and just have the tires installed at a shop then bolting them back on to your vehicle but I dont know how that effects your liability (may the force be with you) in the matter.

Make sure you take and post pictures of your set up if you do this.....Should look like azz.....And be good for a laugh...:
The ricers would like the look....
You had better hope you are very careful driving with these since you will likely destroy your rims on any size potholes,and the outer rim flange wont have any protection because of the stretched tire,,,

A 225/40 is a very short sidewall tire. If the roads in your area get potholed, you'll very likely be bending up those nice rims with so little rubber protecting them.
If you end up going that route, run pressures over 40 PSI to give yourself a bit more rim strikethrough protection.

The load rating for the 225/40/19 @ 35 psi is 1279 lbs per tire, or 2558 lbs per axle, or 5116 lbs for the car.
The 225/40/19 tire is only 1" shorter than the factory tire at 26.1" compared to 27.1", which translates to 1/2" shorter sidewall. Quick math tells you that you have 3.55" of sidewall compared to 4.05".
Now, while a 26.1" tire on a 19" wheel seems short, there are other high performance cars that are running shorter sidewall tires from the factory. The Porsche Cayman R, for example, runs a 25.5" front tire (235/35/19) on a 19x8.5" wheel, and the Corvette ZR1 runs a 25.8" front tire (285/30/19) on a 19x10" wheel.
I'm not advocating that you run the 225/40/19, I personally wouldn't recommend them, but if you don't have the money to buy a more appropriate sized winter tire for the car, than according to the tire manufacturer specs, you will be safe using the smaller 225/40/19 tire. If in doubt, call Bridgestone directly and inquire.
The negatives will be a rougher ride, less suspension compliance, more edgy handling, and less maximum carrying weight. Also, due to the shorter tire running at max rim width, the tire sidewalls won't flex much, and as stated above, you're putting the wheels at higher risk of damage from pot holes and other road hazards.

I wouldn't run the smaller tire. What I'm not understanding is why buy a $30k+ car if you can't afford new tires? Not many tire shops are going to put a tire on that isn't of the factory "door sticker" size due to legal reasons.

You guys might not hear about it that often but I work for a company that does and they get a tire industy trade paper and it is filled with law suits that arise from the improper installation of tires all the time. As an example, placing new tires on the wrong axle cost BFGoodrich and the tire shop 22 million dollars simply because they put brand new tires of the same type, size and speed rating on the front axle. Using outdated flat repair methods cost an company 7 million dollars in another instance and so on.
Fortunately tires are ruggedly over engineered but thats not an excuse for doing something simply out of convience, the job needs to be done right simply because a driver and a car do not operate in a bubble that might only be a minor issue if a problem occurs with a vehicle by itself can easily ballon into a major problem involving several vehicles and thats where it gets sticky because all the people you pass on the highway were in no way involved in the descision to use what could be an overloaded tire.
Personally knowing about the woeful lack of training in the tire industry overall I feel something drastic needs to be done, something more than million dollar lawsuits and firing the tech or sales guys. IMO if they make a bad choice they should be held every bit as accountable as somebody who commits premeditated murder and it needs to be very public with very bad results for that person ( up to life in prison, huge fines in addition to a huge lawsuit).
