    Not real sure on the km on the front bearings Stroker ,around 15000 to 20000km i think ?as after i took them out when i was making the new wheel i gave them a good clean and greased them up they felt ok to use again . The new set was put into the tool box for when we needed them.
    This front wheel is the one where i cut the original hub in half and bolted both sides to a 15x31/2 mag wheel .It is still working great no problems .
    The first front steel wheel i made was to heavy and did not end up to good it was to hard to balance . ,

    Pops, Nice job on that front wheel! You really can't beat those Centerline rims for a place to start when making a wheel for a sidecar rig. They are much stronger than a cast aluminum rim and if damaged can be "massaged' back into shape to get you home. We flycut the mounting faces for the hubs on both sides of the rim to insure true running brake rotors. Cheers:freaky

    THere it is 135/80 Nankang vs 145/65 Firestone Graspic about a 1/4 inch clearance each side in my 1150 fork axle center is 10.5" off the ground handles like a sports car, I see now why the EML's still command so damn much money car wheels work on pavement.DB

    My switch to 65 profile tires front and rear left me with a lowered front end, it handled fine but level is better,I'm straightening up the wiring harness under the tank ( I had ABSi removed and battery is on sidecar frame) so I thought the front should have some attention. I had a put a 12-56 spring on the Ohlins but had not preloaded it at all so first off I gave it a 1/4" of preload then placed a 3/8" spacer on top of shock walla the subframe is level. I think I'm going to remove part of my spacer and put the fatter than I realized rubber washer back between the shock top and the steering head casting. My front shock is Ohlins the top mounting is a stud it can be easily replaces with a longer one if I need a thicker spacer.DB

    I got out for a little tire testing finally 35 degrees still ice under 6-7" of wet snow in unplowed area's. Continental wintercontact worked very well.

    As long as one modulated throttle it kept trying even when we got down to the ice, it kept chewing till I packed enough snow under rig to hang it up.
    The Firestone/Dunlop Graspic whatever wasn't as bad as I figure it would be as long as I kept my turning arcs reasonable she held on like grim death.I think a Karoo or TKC would be better as I wouldn't be pushing such a big footprint, but all and all this will probably be a acceptable all around combination.
    I still am amazed at he handling on pavement there's no substitute for a larger tire contact patch and a swaybar.DB
    Claude thanks again !!!!!!

    The above pair are the tkc and the 145/80/15

    I almost forgot the 145/65 Dunlop Graspic vs the 135/80 nankang, and largest of all was a 19"Metzler Lazar 110/80/19.

    Dave, as seen on your pictures, you have about 2 inches difference, in betwwen the 19" OEM front tire with TKC 80 and the 15" Sstoker rim with the 145 car tire., So your front end has dropped by about 2" (cause the rear car tire has the same height as the OEM 17" MC tire)

    So my question: How important to have a level bike (your seems level) for the handling of the rig, or do you have to raise the front and or lower the back.
    I'm asking because one of my neighbour get the Stroker 2 car wheels set up (not mounted yet), and we were both brainstorming about the importance or no to have a level bike, with no satisfied answer.

    I didn't get my earlier post finished and really should have added one more image I seem to have lost.I've driven this same setup with the 145/65 Dunlop smallest widest front and it was very sporty handling on pavement and gravel.I've driven it with worn out 19" Metzler Tourance that went away very fast in the front, didn't like this much at all. !9"Metzler Lazar 120/80 very nice way better than worn Tourance but not enough tread for anything but pavement and taller than tkc. Best all around compromise is the 135/80 Nankang pictured on the bike, I have not tried the 145/80 yet.I took a tire groover to the 135 trying to make her bite a little harder in the soft bits, I've added even more than in the below image.[​IMG]
    Onward and forward,thru all this up and down the sidecar frame has never gotten any more than half a bubble out of level on a 48" level lay across it. DB

    Just in case I haven't made it clear big tire patches and auto tires are great !!!!!! But!!!!!! When the chair tire starts pushing wet heavy snow your about to get stuck.But what the hell I'm not a Uralista and Urals sure have there place.DB

    just to give you all a laugh related to speedometer drives. if doing a single sided swingarm leading link with adjustable trail, twin brake calipers on the right and using 1150 GS rear wheel on the front be sure not to forget about the speedometer drive near the end of the project when you happen to see It hanging across the seat area in all it's glory. :eek1 LOL......Yes we have it figured out but all of us here at the shop are more bald than before from scratching our heads on this oversight. No, we did not put a bicycle speedometer on it even though it did cross our minds and would have worked. Pics will be in another thread at some point. :D

    Thanks DB
    I guess I'll have to buy a chunk of aluminum and make a pair of adapters large enough for my auto wheels.

    I've been changing and balancing the bike wheels for a few years, but have been hesitant to do the auto wheels. I've been having them done at a chain tire store, but their selection of tires is limited and they didn't seem too happy when I asked about bringing my own tires from another source.

    You guys are fortunate you can run those enormous 135, 145 and larger tires. I am pretty much limited to 125s on my 15" wheels laced to the original BMW hubs . . .

    Not much selection in the 125-15 arena. Michelins or Firestones. Nothing remotely "dual sportish" available.

    Hook up with Stroker and have him build you a front wheel. You'll like it.

    Duncan - the front isn't really the issue. Plenty of room there. It is the rear that is the constraint. The swing arm limits how wide you can go. And my swing arm has already been modified to make the 125 fit (barely).

    I don't know that a much bigger tire would make much difference in how the bike performs. A larger size would just give me more options for tires. I really wish I could find a studdable snow tire in the 125-15 size so I could do some winter riding.
