YES.
Thanks to everyone that chimed in on this discussion. Although in "theory" there seems to be a good argument, all of you that are actually "field testing" with thousands of miles on these rims/tires are proving the "theory" wrong apparently. It still concerns me a bit, but worth a try.
1) I understand that everyone is using the R1 swing arm and rim regardless of year correct? Will a newer 5 spoke style wheel fit on a 2002 swing arm?
2) Will a 2002 engine mate up to a 2004+ swing arm and rim?
3) And the tire of choice is a 205/40/17.
4) And tire pressure of about 20lbs. Correct? I have Sumitomo tires myself for the front already and wanting to match the tread for the rear. So I will see about finding one from Sumitomo on Tirerack.com.
One more question. The rear swing arm and shock/spring, any extra adjustments needed while riding with two people (ground height clearance)?

Arguments why car tire and motorbike rim do not cause problems on a tR1ke.
1. The mass pushing the tR1ke rear wheel to the ground is low.
Rear wheel load I measured: (more or less)
Empty tr1ke: 150kg rear wheel load
tR1ke + 90kg driver: 200kg
tR1ke + 90kg driver + 90kg passenger: 250kg
Fully accelerating motorbike has almost full load on the rear wheel:
Motorbike + driver = 230kg + 90kg = 320kg
2. tR1ke suspension is always 90 degrees to the load.
Motorbike suspension is 90 degrees to the load only when driving straight forward.
In corners it is less. So rear suspension and rear wheel bridge are designed to handle much more torsion stress than it gets in the tR1ke.
3. Real life tests experience proves no problem are to be expected.

If you need this much convincing, you may not be ready for a trike ;D

No.... I am just not 21 years old any more and believe I am indestructible and will live forever. I became "aware" sometime around age 30 (now 37). I still would like to jump into something that has the same 0-60mph performance of a Lambo/Ferrari with no where near the price tag. And go for a drive just to listen to the sound of the cylinders racing, and the whine of the transmission spooling up. Maybe I could start mainlining Adrenaline yet again.
Who has the most unique and custom sounding exhaust to date on here?! :-)

No. Might have some video clips on YouTube. Look up plazmanian username, or green TR1KE

Well here's a very exciting clip looking at the rear wheel, it doesn't look like it but i'm cornering as quick as the understeering front tyres will allow.
The rear tyre's a Toyo 888r run at 19 psi
PS...apologies for the poor sound quality I didn't bother with the external mic.

It's quite mesmerising how the chain slackens and ripples etc
Like a really expensive lava lamp!

Think I saw a cyclist in a one frame, but he was gone so quickly I doubt he saw you ;-)
