If cost of tires isn't the point, and ergo neither is the frequency or expense of changing tires on a single-sided swing-arm as you corrected me on earlier, then why f$#@ with your safety? ..
My comment about you buying it because it was cheap, is a misplaced attribution. Sorry. However i will amend it to say that i think you are being cheap at the potential expense of your safety. A tire and a spare goldwing rim assembly .. a bargoon at $100 eh? How used is the tire? Did you inspect your wheel bearings in that Honda hub before you installed it - bearings also tend to wear harder under the increased centrifugal stresses acting upon them from the increased overall weight of the rotating rubber. Or was it a new darkside assembly that someone chickened out on/didn't follow through with?
Not sure what you are inferring with 'you think bikes are expensive by a boat'. As for the boat (what's the point of this, in this discussion?), if i wanted a boat and had money to waste, i'd just as soon pour a bucket of money straight in the lake, and save me the trouble of scrubbing a hull at the end of season. No thanks. You are also not the only one riding and buying assorted expensive bits since the 80's, so you can stow that holier than thou declaration - again not sure why you feel the need to bring that up.
My 'pointing out of context' was to indicate that YOU have two weeks experience, on an undocumented tire, "that you were gonna give a try, but wasn't sure of" .. that is hardly the safe way of going about this.. taking a second hand rim, with an already mounted, undocumented (second-hand, used?) tire with an unknown history of installation or usage.. and lets give it a try on this darksider thing! You are certainly no voice of experience at this point, to be defending the honor of car tires on motorcycle rims.
PS: I read a few threads about the handling getting all funky at about 5 mph on your darkside forum, as some darksiders transition over a driveway lip onto a roadway.. were you aware - at all, that this is the point at which a fair amount of mis-match bead seat failures occur? That uncomfortable handling feeling is the tire carcass deforming the bead seal as it rolls over the point of the driveway/roadway curb transition and is the precursor to the bead rolling off of the rim while leaned over low speed. All it takes is the softer sidewall to deform more than the bead can maintain seal on the rim. Funnily enough, some of your fellow wing darksiders can't even seem to decide between "speed it up a bit over the transition" or alternatively "just take it easy" as the solution. What an innovative approach on what is symptomatic of a potentially serious safety issue.
The other guys with 13-14 years with millions of miles.. again, unless i see the tire and rim engineers saying it's safe on a single-track motorcycle, IMHO, it really isn't. I've certainly heard of incidents over the years myself.. including incidents on single-track motorcycles, and involving car tires mounted on unmodded motorcycle rim assemblies on sidecar rigs as well.
Also - correct me if i am wrong - but were there not recommendations made for minimum tire inflation at 42-45 psi to compensate for the soft shoulders of these automotive tires, as seen in posts on the darksider's forum?
How does an increase of 5-6 PSI sound, from road friction/changing air temperature internally/external conditions increasing the tires PSI under operation, these darksider wheels are now essentially over-inflating to 47-51 PSI, with dynamic road use stresses involved? Would this not also increase the risk of a bead seal failure in the form of a blow-out, or a roll-off scenario occurring, if there are cornering demands taking place with the tire at the same time? Would this not increase the risk of blistering of the carcass, de-lamination of the tread, or a blowout caused by road-FOD - even on an automotive tire, on an automotive rim, mounted on a car - the correct application for the tire?
The last time that i looked, the Kumho's on my sidecar rig specs label indicated max inflation value being at 35 PSI. I run them just a few PSI less, for a little extra traction in certain road conditions.
But whatever i guess.. there is nothing more to do, but to do your own thing, Fatwing! It's obvious that i am neither going to convince, nor agree with you - and nor will you, with I.
What about the millions of miles that have been accumulated in the last 13-14 years along with my 2 weeks?
You really know how to take a post out of context I'll give you that.What I said was that the tire was already on the rim that I bought for a spare.I said it was a $100 for both.Nowhere did I say that I bought it because it was cheap.Yes I recently went Darkside after a lot of studying the subject.In no way did I do this because it was cheaper,but because it has been proven to work and work well.I've been buying $250 + rear tires since the 80's,so believe me cost has next to nothing to do with this move.You want to play you got to pay.You think bikes are expensive by a boat.
BTW I missed the part about the tire rubbing.That's a different story obviously.
