my 07 outlander has 225/55/18 H rated OEM tries. [/align]Is ok to replace with 225/55/18 V or T rated tires[/align]or is ok to replace with 235/50/18 tires?[/align][/align]

 

"V"'s (higher speed rating than "H") are fine... I would not go with a"T" (slower speed rating than "H")... I would also not change the tire size as thisaffects the height/width ratio and may cause rubbing on turns, not to mention possibly causingyour speedometer to be inaccurate...

......do 235/55/18.

they will be a little fatter. (good!) and the o.d. will be close enuf to stock that speedo error will not be anything to worry about.
