Non-hubcentric wheels and spacers -probably stupid questions

[pardonthewait]

Hi,

These may well be really stupid questions so forgive me but I'd rather err on the side of safety.

The wheels on my superminx aren't hubcentric but lug centric, so the wheels are centred by the wheel studs and nuts.

What's the deal with these if I want to space them out, by say 10mm?

Will the wheels centre properly with spacers in the equation or will it cause me issues?

Can I just get a set of 10mm, 4x108mm spacers and crack on, using the original studs, or should I be looking at fitting longer studs?

The standard wheels and nuts leave about probably 5-6mm of exposed thread.

Again, it's probably a stupid question, but to be honest I don't know the answer and don't want to do anything stupid so a bit of knowledge would really not go amiss.

Cheers

Hey, if you only have 5mm thread left on the studs you would need to get longer ones to work with generic 10mm spacers.

^That. You cannot, under and circumstances, have less thread than nut. And no, don't cheat by machining your nuts down!

There may be 10mm, would have to measure, but I think it's shy of that.

About centering - with lug centric wheels will it not present a problem on that front?

Should be fine.
Id have possible concerns with thicker spacers, but id run 10mm with nutcentric wheels.

General rule with threads is that you have more than the diameter of the thread engaged. So a M12 thread needs a nut should be at least 12mm long.

Good rule of thumb, cheers. On second look I don't think it really needs the spacers. I've had the rears banded to fill the arches and thought the fronts might need a little nudge out but I think it's alright.

All good to know though!
