Make your own Big Wheels?
« on: February 26, 2017, 12:49:48 pm »
Anyone attempt to fab a wheel center?
Precision required to achieve decent balance kinda makes me back off.
Guess I could build a 'lathe' as I think the secret would be the ability to spin the pieces, at least during markup.

Don't know that I would go this far (semi-truck rims). Pics are from an ad on CL a few years back.

    Considering how cheap custom rims are today, there is no point in trying to booty fab something like this.  Plus, flat centers have no strength when pushed into a corner and will bend the centers easily.  Go with some custom wheels with pressed centers that are machine welded and call it done.

    Agreed. Build vs Buy definitely leans to Buy.
    I toured the Centerline factory years ago, and I like the idea of the work-hardened (essentially forged) aluminum centers.

    Flex isn't significant going from 6.5 inch bolt circle to 15-16" rim, but I bet it starts to pose a problem for 6.5 out to 19" (like these), 20" or even now 22".

    Curious how things go in circles. Model T had, what, 30-inch tires?

    Personally prefer to just pick up OEM take-offs, since the replacement tires will always be among the cheapest for a suitable fitment. Problem is, my 8 on 6.5" isn't 8 on 170mm...
    So ridiculously close; 6.693". If I were re-engineering it, I'd have gone to 200mm to allow larger bearings. Sigh.

    I don't understand this.  8 on 6.5" is 8 on 6.5".  8 on 170mm is the oddball Ford pattern that everyone hates.

    My Bad, partly. Chevy switched to 8x180 in 2011, and I had heard that Dodge did a year or two later when they went to metric threads. Wrong. RAM is still using 8x165.1, as you say.

    Offset is still all wrong for an old axle though. Actually, it's the old suspension design that's the issue. Leaf springs vs coil. The coil design allows them to tuck the wheels inboard, so they can put wide tires on and not muddy the side of the truck (too much).

    Okay, I surrender to logic.
    Clearly the wheels are out there if you want to mount over the road tires.

    This guy is selling 19.5" rims and tires for $900. But the tread wouldn't do you any good offroad, and isn't that a major reason for going to larger diameter? Hmm, okay, I suppose if you just want lower final ratio to save gas during a lot of highway miles. But if you're going to do so many InterBore miles, wouldn't you want a modern rig with all the distractions? Justasking.

    I believe that 19.5 are one of those tire sizes thats expected to be phased out within the next few years.
