Just remember that the 'laser' bit is just
one of the methods/tools available to make the task of doing a wheel alignment easier to physically do as well as easier to get it right - but there are a fair few other equally as accurate wheel alignment methods, altho they are usually a bit more complex to do & get right, but that shouldn't be an issue if they are done by someone who is appropriately skilled! :thumbup:
That said, I 'aim' to get all of my vehicles re-aligned whenever I fit new tires and whenever I do any work or driving/ryding that might adversely affect their alignment. On our 4WD's & road cars, that means they get re-aligned & their wheels re-balanced about every 10,000 km, which is also when I rotate the tires front to rear & across, ensuring the tires wear evenly & last a fair bit longer before they wear out. On my Spyder, I do an alignment with every new set of front tires, and like PMK up in post #2, also whenever I do any work that might change the alignment or any ryding that could've upset things up front.... but then I do have easy access to the alignment gear & it doesn't cost me anything!
And I don't 'rotate' my Spyder's tires either, flipping them on their rims then swapping them from left to right & vice versa, which I believe
IS the recommended practice for the OE Kendas at every 10,000km
IF you're lucky enough to have yours last that long! :shocked: The 'flip them on their rims' bit is to keep the directional tread rolling in the right direction when you swap them from one side to the other, but that's not strictly necessary for non-directional tires anyway, altho it might help even out any excessive wear that's happening only on one side of your tire's tread. However, since a good wheel alignment generally means minimal uneven tread wear like that, swapping the tires from one side to the other pretty much becomes an exercise in futility. Sure, it might help the OE Kendas last longer before completely scrubbing out one side of the tread,
IF you are still running on the factory alignment; but if you've had a good wheel alignment done then even if you're still running the OE spec Kendas, they should last reasonably well up front without any scrubbing or scalloping. If they are still wearing poorly despite a good wheel alignment from a competent operator, then it's probably time to carefully check & remedy any front suspension wear/issues before you replace them with a better tire & check the alignment anyway! :thumbup:
