Ghost_Ls8--hey thank you for your response, have you had any problems with your speed odometer being off? Also I have not heard of using different sizing on the LSE, I have of other sports cars, what made you use this combination on yours? Do you have any idea what the difference in the width of the tires are? I really just am interested in replacing my current factory ones with a wider tire. They just look nicer and would help with the handling of the car. Thank you so much for your response and look forward to us talking again. larry
