You don't really get much choice about tire width/sizes do you Martin?! :dontknow: Isn't your country one of those where the 'Authorities' will check your Spyder's papers to confirm the allowed tire sizes - or at least they check electronically to see what's in the system, and then compare that to what's written on the tire you've got fitted.....

So you're effectively restricted to fitting sizes that either match the OE Spec nominal size or that you can show match up to the original rolling diameter & width & then get approval for?! :banghead:
Here in South Aus, besides matching bead profiles & meeting or exceeding the load & speed ratings, we have a size range plus or minus for both rolling diameter and width that we hafta stay within when changing the brand/sizes of our tires.... which I'd think most do at some stage! :thumbup: On our Spyders/Rykers, it's actually pretty hard to go outside that range when going larger without making some fairly significant mods to fenders, steering, &/or swingarms. So for going bigger, those restrictions are simply not too much of an issue.... anything bigger than what's permitted simply won't fit! As to why anyone would ever want to go any smaller than the fairly generous lower limit in the first place is well beyond me! :shocked: Altho I guess I could fit a 195/45R15 on the rear of my Spyder & turn it into a 'tire shredding donut spinning weapon'...... altho the Nanny would probably object & dump it into Limp Mode! :gaah:
Lights are a bit different here tho - basically, if we want to change the OE lights, we can do that just so long as any alternatives we fit satisfy the legislated 'colour, brightness, placement, height, & width requirements' etc.... but there are quite a few bikes, trikes, & imported vehicles that have 'special exemptions' from meeting some/many/all of those requirements in the first place, so unless you really do your homework to start with, it's always a bit risky to change the lights too much!! :sour: But if we decide to
modify the lights that came on a vehicle that has exemptions, the mods only hafta satisfy the 'lines of sight' & 'visibility' requirements as well as matching or exceeding the lumens put out by the OE lights.... and THAT''s pretty hard to measure by the side of the road!

hyea: So there's a good chance that your light modification would be fine here - only we don't whatever we do cover or remove any reflectors!! For some reason,
THOSE hafta be there somewhere; and even if we replace them with lights, they
STILL hafta remain reflective when unlit! :shocked: So I hope the centre section of the lights that you covered wasn't reflective, cos if it was, you won't ever get The Beast registered here! :lecturef_smilie:
