Title: Wheels to fit 4x4"......
Post by: ROD on May 01, 2009, 12:11:42 PM
Looking for some rear wheels.....
 Will 4x100 fit to the 4x4"?
 Some of the wheels I like havent got enuf 'meat' on the hub area to re-drill holes between the existing ones.
 Make up adaptors?

Simple answer, NO, 4x100mm aint the same as 4x4" PCD! Morrag,( if using steel wheels the 4x100mm PCD types, can sometimes be "persuaded" to fit 4x4" pcd, but its not best eng. practice, to say the least!)

Here's some 13" classic mini alloys that would fit

there was a guy on ebay selling adapters already made up 4" to 100mm. I'll see if i can find him.

that set sold, but if you read the listing, he says he has more of them, may be worth emailing him?

Morrag ,thanx .
 Peanut,alot of those about but I need something like 15's with lowish profile tyres ,thanx anyway.
 xj750 ...Ive e mailed the spacer guy! Thanx

if you get stuck and need one, i`ve got a 1:1 scale drawing of the adaptor plate.

I reckon I might be able to make the adaptors myself ,but I'm a bit worried about getting them dead accurate .

As Mr M has said before, the difference in the pcd is only 1.06mm, thats 0.53mm per hole........basically bugger all. While i dont generally disagree with morrag, i personally dont feel its worth the effort and i happily run 100mm pcd wheels on my reliant axle.

'tis true ,its only 1/2 mm. I s'pose it depends on whether the nuts are the type that recess into the wheel ,or sit on the surface of the wheel.The recess type would be harder to get on . In any case,if the nuts werent tightened equally ,the wheel would be pulled to one side?

and dont forget your happy to fit discs with 100mm pcd  ;).
Ultimately the decision has to be yours, but listen to all sides before making your choice.

so the Nova discs fit the 4"pcd ok?


Title: Re: Wheels to fit 4x4"......
Post by: tbone on May 01, 2009, 08:45:00 PM
The wheel studs on the nova are a larger diameter than the reliant, so natuarally the holes in both disc & wheel will be larger too. This tiny size difference allows them to go over the studs, if, like Mr M has done, you replace the original studs with 12mm ones, you`ll need to drill the hubs anyway, unless you are a precision engineer, the chances are you`ll `loose` that 0.53mm when driling.

Mr T when I machine the Reliant hub carrier to accept the Nova discs, I ensure that the disc sits on the new "register" that I machine, and therefore the slight PCD diff. does not become an issue.Morrag

Morrag's quite right to point out it's not perfect engineering theory, but in practice it works fine. Over enthusiastic wheel nut tightening will probably stretch the studs more than half a mill anyway. He's also right about machining the centre boss down to fit the discs so that they centre on the shoulder.
Personally I'm quite happy to run 100mm wheels on 4" studs, but you're responsible for your own safety -if you're not happy, then buy Imperial wheels.  ;)

So, machine the Reliant hub carrier so that it leaves a slight raised lip in the centre to locate the centre hole in the Nova disc. ,then drill thro the stud holes in the disc to align the new 100mm pcd.I was thinking of doing it that way previously ,but wasnt sure how close the stud holes  were to the edge (corners) of the Reliant hub.

Mr T I hate to "nit-pick" but the diff. is actually 1.6mm, around a sixteenth of an inch,100mm to 4" PCD, and whilst I have already agreed that you can get away with this on a 'countersunk' style of wheel nut location, if you are using tube nuts.......Rod, I have redrilled quite a few ex-Ford fittment wheels to suit the Reliant PCD, and there is usually sufficient 'meat' to do so, but I also normally use drilling jig, Morrag

You`ll get no more arguments from me. I`m only a bloke with a shed and a spanner, others here are far more qualified to comment on such topics, if i had a sense of humour i`d restrict my forthcoming posts to humourous comments only.  ;D

Hey Mr. T if I have been too pointed, then please accept my apologies, no offence intended, honest! I will now,"shutta my mouth",Morrag

No offence taken and certainly no apologies neccassary. You have answered the query correctly while i have attempted to voice the opinion of the unqualified shed builder.
Different views are what make forums interesting and dare i say exciting places to be, without people like ourselves who are willing to air their opinions it would be very quiet around here.

Meanwhile ....back on track  ;)
       What Ive decided to do ,is buy some Nova discs ,and use them as a template to re drill the hubs. Coupled with a pair (aint found any yet) of 4x100's this will at least allow me to set the axle height to build the frame. Thanks everbody for your wise words of wisdom . Without the various views on these engineering probs no one would be able to make a decision!There is a fantastic array of grass roots problem solvers on here!
            Regards

If there was never a diference of opinion, we would all be riding and doing the same thing ;)
