The reason why they stipulate using the same tire size and manufacturer at all four positions is to ensure the same overall diameter. What most of you haven't taken into consideration is that while mixed tires may be the same diameter when off the ground, all bets are off when the weight is on. Also consider the fact that with different constructions, materials and tread weights each tire will 'grow' differently at speed due to centrifugal force.
You have bought a vehicle that is capable of excellent ride and handling, why compromise that to save a few bucks? If you can't afford to maintain something properly then maybe you need to shift to a less expensive vehicle. I'm not trying to upset anyone, I'm just spitting out the truth.
