I'll start finding out how well these things help in many aspects starting tomorrow evening, as I'm having the wheels rebalanced (or their balance checked) and then having them put on the vehicle.
I don't have a torque wrench, and considering I just got these, a rebalance is a good idea. I might invest in a good torque wrench and jack for the future. I will be asking how they'll torque, as the Mazda manual calls for 85 ft·lb, yet their inspection said the lug nuts are currently torqued at 100 ft·lb. I don't know how they checked that and if it's accurate.
Won't have much weather until the weekend and who knows if I'll drive during anything, but it'll be consistently in the 30-40ºF range for highs, so I'll at least get cold dry roads to test on, if not wet or a touch snow covered later. And I can compare both performance and road noise that I have with the directional Falken tires currently mounted.
I'll have to have balancing and mounting done in the spring for a new set of tires and wheels then as well. I might be able to get replacement wheels for just the front, but for sure a new set of all-seasons... or, if I'm daring, some kind of performance summer type, but not likely. It's not a turbo or supercharged car, so I can't see it mattering one bit at that point. GOOD all-seasons absolutely, but no high-end summers.
