[Lumps!] mag wheels

The bolt pattern is garden-variety 5-bolt, 4 3/4" circle just like many GM
cars…no problem there. The reason you can’t find any mag wheel listings
is very few outfits make a wheel with a center hole large enough to
accommodate the Jag center hubs…apprx 2 7/8".

Faced with the same dilemma I picked the wheels I liked and simply had a
local machine shop enlarge the holes, using my spare wheel for measurement
purposes.

As an alternative you may want to look at some of the wheels which have been
used on the XJ-S model. For example, the XJ-S “Starfish” wheels looks very
nice on the XJ6 cars.

Tanya & Matt,

First, welcome to the list. Good to have you with us. Great folks on the
list, very helpful and kind hearted people, you will fit right in.

As for the wheels, my neighbor has an '88 XJS and he found that the
wheels (Breyton) that fit a new model BMW 3 series fit his hub and bolt
pattern perfectly. Question is, has the Jag bolt pattern changed from
Series 1 to XJS through the years?
Listers, anybody know?
Back to those wheels, I have seen them and if the pattern works for the
Breyton wheels on the new BMW 3 series, then there are any number of
wheels being made that will also fit that car.
Check out both tirerack.com or discounttire.com , I don’t remember which
one it was, but one of those places has good pix of the wheels.

David,
I am certain that XJ6 and XJ-S bolt patterns remained the same at least up
to the point when the new style rear suspension was used.

Not 100% certain but I think the suspension changed in 1992 for the XJ-S
and, for the XJ6, the change came with the XJ40-type cars. Not sure of the
bolt pattern on these…could still be the same for all I know.

Yup!

The bolt circle stayed the same but I’m not sure about the offset…

I know that some of the XJ-S guys are using XK-8 wheels…so I’m thinking
that Jaguar has retained the same bolt circle on their cars…dunno 'bout
the S-Type though…

Doesn’t Rich Neary have XJ-40 wheels on his car?

XJ 40 bolt pattern is the same as SIII however XJ 40 wheels are 1/2" wider
and require a 1/4" spacer and aftermarket lug nuts to work on the front of
the SIII. rears are a direct bolt on using stock lug nuts. Can’t comment on
what fits what, but my undestanding is that all XJ’s XK’s and XJS’s have
4-3/4" bolt pattern and the new S type is different.

regarding wheel interchangability, here are two clips from my personal
archive, which unfortunately lacks any source information for these posts.
the first could be an extension of a posting on wheels and tires i have
attributable to steve chatman, and is brief though comprehensive, as proper
offset is discussed (offset is the difference between the wheel’s true
centerline and the face with the lug nut holes as measured from the back,
the author thinks [and i agree], which is important for maintaining proper
suspension geometry [don’t go too far either way, or it will give you
grief]). The second is an interesting tidbit if you are considering going
“all the way,” and is unfortunately also without an authors name:

first included post >>>>>>>>>>>>>

All XJ rims are interchangeable as far as stud pattern and offset goes - the
16" and 17" rims off the X300 will happily bolt on, note the XK8 rims won’t
however.

The XJ uses a PCD [diameter of the circle formed by the studs] of 4.75" on a
5-stud pattern with a 27-33mm offset depending on model. The additional
offset of the later models won’t cause you any grief, and it allows slightly
wider tyres.

The PCD / stud pattern is also the same as most Chevs (and many GM’s world
wide i.e. some Holdens, Vauxhall’s and maybe Opels not sure on the last),
but the offset varies a great deal on the Chevs’, so while some offsets will
work, other’s won’t.

second included post >>>>>>>>>>>>>

I’ve got 17x8 rims on my XJ S1, backspacing is 5 3/4 inches (I ordered them
with this custom backspacing so they would fit). They fit great and no
rubbing, even on a lowered car. There is little room either way. Also 8
inches is the practical max on an S1 - might be able to squeeze more with
minor surgery on the guards or on a later model.

hope this helps,
-slats

Hi,

if you want to go all the way in an S1, 17x8 fits with between 5 1/2 and 5
3/4 inch backspacing without rubbing anywhere, but things are real tight, so
try before you buy.

ROH makes a wheel called the ZS which is 17 x 8.5, P30 offset, 5 x 120mm
(metric, very slightly different to the jag PCD of 5 x 4.75 inches). I run
these wheels with 235/45/ZR17 tyres on my racing 454 S1. I had a steel ring
inserted into the rear of the wheel that was a tight fit on the machined
centre area of the hubs, and this keeps the wheel centred, meaning that the
minor stud pattern difference was of no consequence. I can vouch for the
absence of any vibrations up to 140 mph. I also had to have the centre bore
of the wheels enlarged to clear the jag front hub extensions. All up these
wheels were still way cheaper than anything else i could get in a similar
size for the car. The other issue was that they require the use of rod ends
in place of the OEM balljoints on the outer steering ends due to
interference. This requires the use of a male rod end and some hex stock
internally threaded to join the male steering rod to the male rod end - no
big deal, but requires replacing sooner than a balljoint because of the
potential for rapid wear due to the open nature of the part and the presence
of road grit etc. If that sounds too hard (I wouldn’t do it for a daily
driver myself) it’s hard to beat the 16x7 steel wheels that came standard on
poverty-pack X300 sedans. These are a bolt on.

Don’t get caught with Chevy wheels with insufficient backspacing. very few
will have the required positive offset to work.
