Hi Flemrod, welcome to the Forum. :2thumbs:
Sadly, posting your questions in here will not help too much, cos very few members actually come in here to check out all the new joiners all that often, which is why
SpyderBOT's post above yours ends with the message:

It shouldn't take too long for all your joining processing and checks to be completed, and once they are, you'll be able to either add to any existing threads on the subject (it
ALWAYS pays to do a search first!

) or start a new thread asking your questions, only do please try to briefly state your question in the thread title, cos that'll help anyone else searching for the same or related info, now or maybe years into the future!

However, you do realise that all Spyders come with Power Steering (DPS) don't you?? :dontknow: The early versions, pre 2013 in particular, did have a lot of issues with that, and many failed early in the piece so that '2nd or later' owners never realised what they were missing! So if your wife's 2011 is hard to steer, there's a very good chance that the DPS isn't working as well as it should, if at all! :helpsmilie:
So that pretty much means that your wife really shouldn't find steering a Spyder all that hard!! I certainly haven't, despite the numerous rounds of shoulder surgery I've required to repair the somewhat significant damage that contributed to me being 'retired hurt' after serving in the Oz Military. In fact, after my first bout of shoulder surgery proved the point to me, from there on in not only did
I find that riding my Spyder early on was beneficial and actually helped my recovery after every round of surgery, but all of the various Doctors, Specialists, Ortho Surgeons, & the Physical Therapists I've been treated by are now convinced that (relatively gentle, at least initially!

) Spyder Riding has contributed greatly to my long-term recovery, regaining almost all of my 'pre-injury strength' and despite their fears otherwise, a
full range of movement - I can raise both hands straight up above shoulder height and even have almost full strength at full raise too, all things that they were all
sure would
NEVER happen due to the extent of my injuries! :yikes: But Spyder riding was a stress free movement exercise that gradually increased my strength and range of motion as I worked up to it - along with other PT as well, of course.
Besides, these Spyders and Rykers we ride come with
CAR type 'J' Rims & beads, CAR type steering, and CAR tires, altho admittedly, many find that the OEM tires are really pretty crappy and just about any reputable &/or good quality car tire you might fit is likely going to work better in every respect anyway!! nojoke
As for going wider on the rear,
DON'T!! :yikes: Altho I doubt you could go much wider anyway, there's just not that much room; but the Spyder is very light and already has an over-wide tire for its weight & power etc, so much so that the OEM tires will pretty much
ALWAYS wear out in the middle due to them 'ballooning' so that you only ever run on the middle few inches of tread at the best!! :lecturef_smilie:
So going narrower up front &/or going wider on the rear as you've considered is only
likely to detract from the Spyder's Road holding & handling capabilities, while going slightly larger up front, saaay, to a 165 or 175/60R15, and slightly
narrower on the rear, saaay, to a 205/60 or 215/55 or 60R15 (instead of 225/50) with good quality car tires and running them at a (lower) pressure (18 psi all round for a/mkt car tires is a good start! But
NOT for the OEM tires, their lighter construction
needs the higher pressures listed on the tire placard to perform even as poorly as they do! :sour: ) which is more suitable for the better tires under the lighter load they're carrying, and that will tend to improve
ALL aspects of your Spyder's ride & handling, as well as allowing for easy steering - just so long as you don't go too low (14 psi is about the minimum for the Spyder's loading.) :lecturef_smilie:
So I wouldn't go planning on fitting motorcycle tires just to make things easier for your wife, as I really doubt you'll actually be
helping her at all, more likely the opposite!! :banghead: Still, there's lots of info and numerous threads on the Forum already discussing tires and pressures at great length, so while you're waiting for your joining processing to be completed, you could do a bit of searching and a lot of reading! :thumbup:
Looking forward to seeing you out on the more frequented public pages soon! :cheers:
