In order to keep your speedo fairly accurate, you should have 265/45/18 tires on your rear wheels. The 256/50/18 tires will be too tall. Also, make sure that your wheels are 9" wide to accomodate the 265s.

A 255/50/18 would be the better choice to keep your speedo accurate. The 55 series tire's diameter would be too large. Look at these tire comparisons: http://www.1010tires.com/Tools/Tire-Size-Calculator/225-50R18/225-60R18/255-55R18/255-50R18
