Check to make sure that 'rub' on the right front fender isn't the wiring or a screw head touching the side of the tire, but I'd think it's more likely that you're running juuust a tad too much air in the tire - 18 psi in ANY Spyder tire, front &/or rear, is
more than enough to carry a well overloaded Spyder with a heavy rider, and while a half a psi isn't usually all that much in the overall scheme of things, that could be the half a psi that's causing your tire to rub when you're turning. And while I'm talking pressures, you really don't
need (or likely even
want) 22 psi in the rear - 20 psi,
maybe, if you're running for hours at a time, fully loaded (or over-loaded!) at high speed, on hot roads, & in hot conditions, but that sort of pressure is not really ideal or necessary for anything much less, and so it will be compromising your rear tire's wear, traction, performance, & wet weather capability!
It might take you a bit of a while to get used to running lower pressures than you're used to in these tires, but they
are car radials running on
car rims under a lightweight vehicle, so they
will feel a little different to driving your car &/or riding on motorcycle tires, they are
MEANT to feel different!! And they work differently to motorcycle tires too, the contact patch on a motorcycle tire changes shape as you lean, that's a big part of how they work - for a motorcycle, but you really don't want that to happen on your Spyder!! So the sidewalls on your Spyder tires (whether they are the lighter construction OEM tires that need more air to do the same job, or these stronger built more capable car tires that don't need that much air pressure due to their heavier construction)
need to be able to flex somewhat more than a motorcycle tire in order to keep the whole tread face/contact patch in contact with the road surface as you drive/corner etc; to allow the tread in that contact patch to flex and mould over/conform with any irregularities on that surface, all in order to maximise your tire's grip and let them work their best for you, especially in the wet; and to work with the suspension to give you a controlled and smooth ride - and over-inflating them,
even just a little, starts to degrade all of that so that they won't be quite up to doing their best for you - and when running a 'proper' car tire instead of the lightweight Kendas, over-inflating them by just one psi or so
WILL cause them to wear quickly in the centre, as well as compromising their overall wear, traction, performance, & wet weather capability!
