Scrutineer, that block you have marked 'A' is a groove 'breaker' that helps stabilise the tread & make it do what it should with water etc, it is NOT a tread wear indicator! There are generally no markers on the side of the tread or on the sidewall of the tire to show where to find these, but there is generally at least one in each major groove of the tread.
The block you have marked 'B' looks like it IS a tread wear indicator and so there should be a small raised triangle embossed on each side of the tire tread that lines up with that block - the triangle is just a raised triangular outline about 1/4" across and 1/4" tall that is really located just on the side of the tread, not down on the sidewall of the tire. There should be 3 'lines' of those tread wear indicators with a similar block appearing in each of the major tread grooves around the circumference of the tire, & each 'line' should be identified by the triangle markers appearing on each side of the tread to identify that they are the tread wear indicators.
Your tire doesn't look too bad (yet, anyway - it should have a couple more thousand miles in it.) but the CanAm specified Kenda tires are really not much chop for anything apart from keeping the metal of the rim off the road - while for all intents & purposes they are constructed identically to an (exceedingly lightly constructed) passenger car tire that runs on a rim with a 'passenger car' design bead holder & they distort significantly when running at speed, increasing the wear in the middle of the tread well beyond that experienced by anything else; somehow BRP & Kenda have managed to get them classified as a 'Motorcycle only' tyre & claim that the VSS has been tuned to work
only with them at the risk of failure.... and yet the manufacturers of these stability & safety systems & all other tires all aver that
any tire which matches or exceeds the specified speed, load, wear, and weight ratings for the Spyder & doesn't exceed the rolling diameter by any more than about 3/4" will work perfectly well within the safe operational parameters of the safety systems & vehicle use - btw, it's actually Federally mandated that they do so.... that's what those ratings mean! :shocked:
So if you feel that way inclined, when the time comes around (& it doesn't look like it has yet) you can replace the Kenda tire with an OE spec tire of the same make from a CanAm dealer & put up with the cost & aggravation as well as the poor ride, handling, & tire life;
OR if otherwise inclined, you can fit a higher load speed & wear rated passenger car tire that exceeds the operational ratings of the Kenda crap in all respects & provides far better ride, handling & tire life, usually at a significantly lower cost than that charged by the CanAm dealers for the OE rubbish - I got less than 3000 miles out of my original Kenda rear tire before the canvas started to show & yet with little obvious signs of wear have already exceeded
3 TIMES that with the (funnily enough, cheaper....) replacement passenger car tire that is rated higher in all respects than the Kenda & at least for me, works better in
ALL respects too!!
Over to you.
