ADVICE ON TIRE SIZE PLEASE!!! I want to put 265/40-18's on my 01 gt but i read somewhere that increasing the diameter of the wheels/tires will result in a loss of torque. the rims i am getting are 18x9. i like the 40's because they fill up the gap nicely. i would appreciate some advice on what tire size i should get. thanks. also are 275 too wide to put all around.
