Hi all. Thanks for any help you can give me with my first post. I have asked this question on the SIP forum but had no answers yet... http://www.sip-scootershop.com/Communit ... 35623.aspx
I am customising a VBB into a street racer - P200, PK fork/discs etc... Hoping to go wide tyre (as wide as possible while still being affordable and sensible). I like the idea of tubeless. Was thinking SIP Tubeless Wide Tyre Rims. 3.00-11" (Art.No. 83048000) with 130/70-11's for the rear and 2.50-11" (Art.No. 83058000) with 110/70-11's for the front. Plan on using Jockey's Boxenstop Serie Pro Engine Mounts (Art.No. 17474200).
I have a few questions about this setup, and if there is a 'better' setup.
I like the idea of maximising wheel diameter. Almost 12" without the $$$ conversion. But going 11" seems to severely limit tyre options. It seems the Heidenau K61 or K62 and the Meztler ME 7 Teen are the only options (130/70-11). No ContiTwists in 11". And it seems the Metzler doesn't come in 110/70-11" so that really only leaves the Heidenau tyres? Unless I go 10" on the front with 3.50-10" tyres. The SIP article for the 3.00-11" rims (Art.No. 83048000) states, "Because of its wider rim width we recommend the use of a 2.50-10“ SIP tubeless rim at the front." Does anyone know if there any issues with the 2.50-11"? Will there be be issues with fitting a hugger on those 1.5cm radius bigger tyres? Perhaps the 2.50-10" rim is a better option on the front for these reasons?
I see the 10" SIP Tubeless Wide Tyre Rims have been discontinued (81048000)... Why was this? Seems I need to solve the problem at 11" if I want tubeless (which I do). I also note the catalogue hasn't been updated with the 11" version.
Any other comments or suggestions about this setup welcome. Thanks =)

Not meant to. Many kits have spacers for the hub to shift the wheel away to the left. Cut the engine mounts to move it all (mostly) back in-line to the right. The SIP tubeless wide tyre rims are machined so they don't need a spacer.
I've solved one of my questions tho. Re-did the calculations. A 110/70-11 for a 2.50-11 rim has the same diameter as a 100/90-10 (~3.50x10) for a 2.50-10 rim. The 11" setup is 10% wider and has 15% less sidewall. (But is also offset 4mm left). Also, the only tyre that comes in 130/70-11 and 110/70-11 (also 100/90-10 and 3.50x10) is the K61. Guess it's not a bad only option...
