Correct. Diam diff is three tenths of an inch, with the front being the taller tire. Doesn't sound like much but over time can be enough for trouble.

 

Simple solution, use 215/45/19 (fronts) 245/40/19 (rears) for a overall height difference of less than one tenth of an inch. The difference in rolling circumference is less than half of one percent. Insignificant. And the rear tire is larger than the front tire, the way it should be.

Yes I'd prefer zero, but suddenly driving staggered rims on a G37x doesn't sound quite as scary. Just use 215mm wide front tires.

 

can i see a pic of the coupe x with the 19s since i have the coupe x with 18s and id LOVE to see how it looks. thank you.. u can email me at bmwbusiness007@aol.com thanks

 

i would also like to see pictures as well please post them

 

I actually have the sedan X, not the coupe. I would imagine that the X coupe with the 19's would look almost the same as the regular coupe S but would sit just a tiny bit higher.

 

i just want to see after market wheels on the awd coupe

 

Neal is this statement correct?

 

Of all the tire brands we carry none I have come in a 215/45-19. Wonder if the FREE meant 225.

 

if it is 225 what is the rolling diameter

 

The 225/40-19 is 27" tall.

 

and what is it for 245/40/19?

 

26.7" would be a tad shorter than the front tire.

 

I have a 04 awd and I am running staggered. Run 225/40 f and 255/35 no problem what so ever. I even drove from Seattle to Cali, got a flat and ran a 235/50/17 spare and had no problems.

 

19's or 20's ?

 

i got a 2007 G sedan X and i got the vossens cv1's 20x9 front 245/35/20 and 20x10.5 285/30/20 and i have no problems except for when coming off a pkwy ramp reall hard on the turn my rpm's are getting stuck as though my awd system is leveling the power to the wheels until my car goes flat again. this is driving me crazy but other than that i have no problems
