Attention resident wheel doctor Mr Chris York! And anybody else who has fitted 15" Vitesse alloys to their P6. Will these stunning billet aluminium Rostyle replica wheels fir my P6? Check out the following link: http://wheelvintiques.com/shopsite_sc/store/html/page8.html
I'm thinking about 15" or even – wow – 16" with 6" rim.
The PCD is different, right? Perhaps they can supply them with the right bolt pattern, but will that backspace fit in the restricted rear arch? I will have very tight urethane bushings and stiff shocks, but don't want the inner sidewall to scuff the trailing arms or the outer sidewall to scuff the d-post.
I found a set of tantalisingly close-but-not-actually-the-right-PCD slot mags last winter, but these little beauties are way nicer. What say you, fellow red-blooded V8ers? What with the dollar doing badly, and my 40th birthday approaching, and being in need of a serious cheering up what with my rebuild being so far from finished, I thought I'd ask you all before I make another bad purchase!
 
My word they're georgeous!

I'm afraid the thinking cap is going to have to go on for more than the customary 2 secs though! Once I've got my head round inches to millimetres (I know I was brought up on inches but it's a very very long time since I last used them!) I'm going to have to have a think about pcd's as well. Looks like there's enough choice it ought to be possible to sort something out with the right combination of width and offset though.

Mmm, looks like the yanks measure their wheels by something called "backspacing". NOT the same as offset! Oh dear. Means that for the same offset you have to calculate the backspacing affresh for each rim width. 4 letter word.

Well primary snag is the stud spacing. P6 is 5 studs at 127mm or 5" pitch circle diameter. These wheels are 5 @ 4 1/2 or 5@4 3/4. Unless they are prepared to drill some specially that looks like curtains. There has been extensive discussion on here about using a different pcd and the consensus is that it isn't possible. Adaptor spacers push the wheel out too far, the hubs have bosses cast in where the stud holes are drilled so you can't redrill a few degrees off.

I'll carry on and look at the "backspacing" just in case.
 
OK here goes for the "backspacing".

Key passage on my SD1 Vitesse wheels is: "I have measured up the modified wheels and get a dimension across the outside of the wheel of 190mm and a depth from the inner rim edge of the wheel to the contact face to the hub of 148mm. By my calculation that gives an offset of 53mm into the car. The figure for the offset is unaffected by the rim size (it is relative to the centre line of the rim) so this dimension could be quoted when buying any width rim to give an exact central location within the wheel arch."

So the "backspacing" as defined by the yanks (Diagram to show "backspacing") is 148mm. 5 3/4" is equivalent to 146mm. I should think you'd get away with that provided you didn't go over 205 section tyres.

The Vitesse wheels are 7 1/2" overall width. I'm pretty sure this is 6 1/2 J, ie 1" for the two rim lips to hold the tyre in.

So your looking for a 6 1/2" width rim with 5 3/4" backspacing. Diameter doesn't matter here - just affects what profile of 205 tyre you use. eg for 15" the correct profile is 205/65, for 16" 205/60. 17" and 18" don't have a close diameter equivalent.

Looks to me like the closest they come is 17" X 7" in a 4 1/2" pcd with a 5 1/2" backspace. I reckon that's pretty well cock on for offset but they would have to make you specials for the stud spacing. Tyres would be 205/55 for slightly larger diameter (657.3mm vs 651.6mm) or 205/50 for slightly under diameter (636.8mm vs 651.6mm). Provided I had an overdrive box (LT77/R380 manual or ZF HP22 or HP24 auto) I'd go for the 50 profile in the knowledge I'd have to get the speedo recalibrated. A smaller diameter helps things fit in the arches.

Over to you to see if they'd do a special stud spacing.

Thank you Chris for your prompt and comprehensive reply. I knew you'd be the man to ask. Special merit for wrestling with the problem after midnight. You have accrued a good quantity of beer tokens for your stalwart service, albeit redeemable only once we meet in the UK! Once I finally get my car back on the road I'll have to come back over to Blighty and socialise with other club members at a gathering. I was at Blenheim in 2003 in NKT599M, before I realised just how rotten the base unit was!
Wheel Vintiques also make these 'Magnum 500' Rostyle replicas in steel, for considerably less money (those alloy billet wheels are ever-so expensive). I'll get in touch with them today and enquire if they can do a custom-drilled set to fit the P6 bolt circle. They just look sooooo 'bling'!

i`m in two minds how to fit the jeep 17`s i`ve got onto my p6,one option is the spacer method previously mentioned...have found a seller on ebay that is considerably cheaper than the usual $100 for 2 that i`ve come across,the interesting thing here is that you dont have to stick with the 5 x 5 pcd,the inner ones obviously do but you can have a wider range of outer pcd to match your wheel,if you employed this method you wouldnt have to worry about asking for alternative (read expensive!) pcd,just remember the jeep uses 1/2" unf threads not 7\16" like the rover!!

im thinking its easier to order those gorgeous wheels with a different back spacing to match in with the spacers than it would be for them to change the pcd too??

there was a set of jeep wheels for sale a few months ago on ebay inc the wheel adapters,i contacted the seller and he said he had had the adapters machined down,narrowest i have found so far are 1 1/4 inch so i guess you could go narrower but i dont know how much he took off

hope this helps a bit

Jeep alloys are the same pcd as the rover, so it's just a case of getting the offset right to clear the arches, if you need to space them out then you just need standard spacers (not adaptors) which are quite cheap. Problem comes if you need to bring them in.
 
Re: Will these drop-dead gorgeous alloys fit on my P6? - Billet

the wheel adapters are quite useful even if you are keeping the same pcd..to get the jeep wheels on you will need longer studs x 20...spacers x4 and then get some spigot rings machined up to centralise the wheel...used spacers a long time ago...had lots of wheel vibration because you cant centralise them...never again!!...the adapters are bolted on straight out of the box...overall cost is about the same and less hassle
