I changed mine to hankook v12evo2, differences are noticeable. All roads surfaces sounded like newly paved roads on the factory fitted tyres. My radio volume now turned down by 2 points on my favourite channel and can talk with passengers without raising my voice a lot now. Wind noise exceeds tyre noise by around 130km/h, when previously the toyo so damn noisy after 60km/h. Very surprised that it made such a difference.
Rolling resistance also a little lower, so can improve acceleration and fuel consumption a little bit. It really changed the driving refinement in city speeds quite drastically.
If you can wait a little longer to change (after september), i would suggest the soon to be released falken fk510 which has even better rolling refinement rating than the v12evo2 while selling around similar price range.
So my rant to mazda : Please rid yourself of fitting toyo tyres at factory. If you want to support japan products because you're japan company, fit it with falken fk510. It is cheaper yet better than the toyo in both price and performance metrics!!!
it is about RM1800 if refer australian website, but likely around 2500~3000 when installed. Seriously considering this but not in a hurry at the moment. Thinking of maybe changing it on the 5th year of ownership.
The kruk kruk noise can also be contributed by :
1) the strut bearing
2) the strut mounting
3) the top of the coil spring hitting the strut mounting
4) brake caliper movement
For me, i've done warranty claim on parts 1 to 3, but didn't resolve till date. Point 4 was discovered by a neighbourhood small franchised dealer. The mechanic there dismantled the front caliper and added more lube on the caliper pins and the pin chambers. It reduced the noise occurrence drastically, but only for a short 1 to 2 months period

Seems like a similar incident to a number of previous generation's mazda3 due to caliper pin design. Not sure whether this is an issue to the facelifted GVC version.
Same thing happened to me. The kruk kruk noise cannot be solved despite numerous visits to Service Center.
1. Replace the Lower arm [x4 times]
2. Replace stopper [x2 times]
3. Replace Strut Bearing & Mounting [x2 times]
4. Replace Brake Caliper [Greasing & EVEN IMPROVED PIN]
Other Items replaced:
1. Engine & Gearbox Mounting [vibration during idling]
2. Pulley Tensioner [leaking] x2
3. Wheel Nut rusty [QC issue]
4. Low paint quality - easily to get Stone chip [vs other cars]
I think is boils down to the design defect which unable to solve even on new CX-5 there are complains regarding this kruk kruk issue.
