So you are suggesting that Jack's friend, the owner of DT, is feeding him a line? I'll take Jack's word over your supposition, thank you.I also don't by the line that any aftermarket tire seller was told by BRP not to sell tires.... I think that's just a way to pass the buck and get out of doing them out of fear of liability.
:agree: And with the thousands and thousands of successful, real world test miles that have been logged I'm going to stick with auto tires and never look back. I bet there have been just as many miles put on spyders with auto tires as there has been with OEM's, if not more.I'm not a tire expert but I don't believe a spyder uses a tire at all like a motorcycle does but more like a automobile.
Bingo! By jove I think you got it!:shocked:I'm not a tire expert but I don't believe a spyder uses a tire at all like a motorcycle does but more like a automobile.
This was brought up in another thread and I believe it needs it's own thread. When mounting a car tire on a motorcycle rim these are the reasons it is not recommended.

Does anybody remember who posted those pictures; I lost my computer that had them...pps:

The Spyder rim does not look like a car rim to me. More like the GW rim above. Look at the huge bead humps just like the motorcycle rim above. Car rims don't have that. There is no dropwell either. Only difference I see is the cut down on the sprocket side to allow for an angled Schrader valve to be used.

Rob,
Thanks for (hopefully) putting this one to bed! :thumbup:
OK, I was at Netzley Tire yesterday to have a new car tire (Yokohama s-Drive) installed on my Spyder. I can assure everyone, as can Ron and Derrick Netzley, that our Spyders have rims with an automobile bead design, and NOT a motorcycle bead design, per the diagram above. While my wheel was off, we took a very close look at it and also compared it to another car rim that was also in the shop. The bead area was exactly the same.
While the Spyder rim has no "drop well" like the automotive rim in the diagram above, the bead area, both width and diameter were the same. It looks nothing like the motorcycle rim shown in the diagram. Especially significant was the diameter of the bead lock area, which on the Spyder rim is the same as an automotive rim, and not nearly as sharp a curve as the motorcycle bead.
FWIW, I had a Yokohama s-Drive installed on my Spyder, and the tire tech said it fit absolutely perfectly - even better than the original OEM Kenda tire, which is a tad too wide for the rim. The s-Drive was about 1/4" narrower than the Kenda (205/55R15 vs. 225/50 for the Kenda).

:thumbup: Now we need Steve to come in and tell us why BRP emailed Discount Tire not to sell us Kumho tires :dontknow:.
You actually provided your own answer to this issue... :roflblack:
But BRP can justify this, by reminding everyone that "only motorcycles tires; belong on motorcycles..."
They have to suffer under the watchful eyes of Federal regulators; we don't! :yes::yes::yes:
You're dreaming again Bob. Not a Chance!
Dave,:thumbup: Now we need Steve to come in and tell us why BRP emailed Discount Tire not to sell us Kumho tires :dontknow:. Jack got that info from the owner of DT. I hate companies that lie to customers ( Steve said they did not do it) to make them buy their over priced parts. Anything sent to dealers discouraging them to mount car tires is bogus. Shame on you BRP :lecturef_smilie:
