Do you know 255/45/19 will fit on the stock rear rim?In terms of actual performance in the snow you need 18 inch tires...check out this from tirerack.com
A Minus Size Tire and Wheel
Minus Sizing is simply traditional Plus Sizing techniques used backwards. For example, a 2003 Volkswagen Jetta GLX VR6 would store its original 205/55R16 (or optional 225/45HR17) tires in favor of Minus One or Minus Two size 195/65R15 tires on 15" wheels.
In both of these examples, not only would snow traction be enhanced, but the cost of a Base Model or Minus Size winter tire & wheel package is usually lower than a package maintaining your vehicle's original size tires and wheels.
So for us M guys - you go with 255/45-18 all around.
I may have to upgrade to 19s...as many have said - the 18s sure make the car look...well...plain. UGH!while tirerack is correct...I run 255/40/19 and this is my 3rd winter on Blizzak LM-22...i have 8 mm of tread left...no problems driving in last weeks 12" snow dump....
so for the majority of us...19's will work just fine
I run OEM M6 staggered wheels with Blizzack LM-22 in size 255/40-19 all around based on a recommendation from Tire Rack. They work great, both for cold weather (below 40 degrees F) grip and traction in snow. No complaints at all.Anyone have experience with the blizzak lm 22?
By the way this will be the first winter I'll be driving this car.
