Can I put ( 4 ) 225/45/18 blizzak lm-22 on my '03 6m/t coupe with sport package? I know the original pilot rears are 245/45/18. Will this cause a problem? Thanks.

If you want to use the stock rims you can use 225/45/18 but only for the fronts for the rears you will have to use 225/50/18 or the stock 245/45/18. Good luck trying to find a matching front and rear pair in 18" size, I tried and no luck. Anyway for the price that those will run you, you are better off getting a cheap set of 17 inch rims and 225/50/17 front and 225/55/17 rears, thats exactly what I did.
