If you are still running the OE Spec Kendas, then there
WILL be a small triangle embossed on the sidewalls in alignment with/to indicate that the bars you are looking at are the tread wear bars. :lecturef_smilie:
If you can't find those triangles on the sidewalls in the immediate vicinity of the bars you are looking at, then you
ARE NOT looking at Tread Wear Bars; you are most likely looking at the Tread Block Stabilisation bars or if you prefer, the Groove 'breaker' bars - these are a little larger that the tread wear bars, generally start out with ribbing across their tops, and are designed to lessen block squirm & force any build-up of water/slush/ice to 'break out' out of the grooves as the tire rotates. They will wear level with the thread surface a fair bit earlier than the tread wear bars, and you'll be waste maybe as much as 1/3rd of the tire's potential tread life if you swap based upon those rather than the Tread Wear Bars! :shocked: So look
VERY CAREFULLY for those embossed triangles.
Btw, the Tread Wear Bars or indicators on
ANY tire are 'meant' to be clearly identifiable as '
Tread Wear Indicators' or prompts to replace the tires - most have indicators on the sidewalls/very edge of the tread adjacent to the bars, while some have labelling cut into the centre rib of the tire, labelling that starts out reading something like '
Tread Wear Indicator' that wears down to end up saying something along the lines of '
Replace Tire Now'! But the point is, there
SHOULD be a clear indicator that the bars you are looking at are actually the Tread Wear Bars...
if not, then they probably are not! :thumbup:
And yes, I agree with ThreeWheels, who has clearly identified your best course of action -
Dump the Kendas at your earliest convenience.
