I recently talked with my local auto custom shop about a 1 1/2" suspension lift w/ bigger tires. Since the TB is so new, they could not find a compatible kit. But I am still moving forward with bigger all-terrain tires from my RS stock 225 / 55/ 18 to 225 / 65 / 17 Falken Wildpeak Trail. I understand my speedometer will be off by over 2 mph at 70 mph. Has anyone had any other issues after changing out tires (performance, braking, acceleration, etc)?
