I would not think larger tires would effect anything. On the civy trucks, there are sensors on the wheels to sense a difference between any of the wheels. If the fronts are going 0 and the rears are going 35 then the fronts are locked up. I do know that larger tires does effect the computer as it wants to know how fast the truck is going. I would bet the 900 series kit has a sensor system also as this is the only way I know of to tell if one or more axles' brakes are locked up. I could be wrong. It has happened before.
