I’m sure this topic has been discussed several times before in this
forum. Have made some search, but haven’t been able to get a final
answer. Pls excuse me for posting this topic once again…
I own a late pre-facelift convertible with the 15’’ lattice wheels.
To be able to get tires more easily (and have a wider choice), I am
about to buy a set of original 16’’ lattice wheels from a newer Jag
(not aftermarket wheels). I see these are wider (8’’ instead of
6.5’’) and have a different offset (33mm instead of 28.5mm).
So here go the two questions:
a) Have been told this is a direct bolt on. Is it true? Don’t want
to make any suspension and/or body modification (to fenders).
b) Which is the best (biggest?) 16’’ tire width/profile combination
that I can put that gives the closest rolling diameter to the
actual 235/60-15’’ tire and does not interfere with the body or
suspension of the car?
(“Convert P-metric Tire to Tire Diameter Inches”) from Currie Enterprises.
This will calculate for you the unloaded diameter of various tire and wheel
combinations, just plug in the tire and wheel size.
There are a haf dozen calculators on Currie’s site related to rear end
variables (wheels, ring and pinion, speed etc).
QUESTION:
What year and model Jaguar offered 16 inch lattice wheels? An xj-s? If not,
is the lattice pattern the same as an xj-s? The subject has come up before
but all I could find was two widths for the 15 inch wheel (6.5 and 7.0). I
couldn’t validate that a 16 inch existed.
You are probably aware but:
Bernie Embden’s photo essay on his web site is likely the definitive
statement on measuring for wheel width and offsets on the xj-s.
The TWR Jaguar Sport Conversion (and the similar Lynx Conversion) used 16
x 8 inch wheels (not lattice) and photos of these cars are in the brochures
section of jag-lovers. One of those cars pictured used 225/50VR16 front and
245/55VR16 rear. I think it’s an '89 brochure.

Stephen,
Tks for the info and for the calculator web page. Tks also to the
other lister who suggested another page in a private message. Yet,
the really ‘‘difficult’’ part of the question is not the diameter,
but the appropriate max width that can be fitted without modifying
the fenders/suspension.
Tks also for suggesting B. Embden’s page. Have been there in the
past, but had forgotten to check this time. As there is lots of
info there, I’ll check it later with more free time. Though it
seems more oriented to 17’’ and not 16’’ wheels, anyway width of tire
and offset info should be OK too. Don’t you think so?
Regarding your question, I have no idea in which cars (and if an XJ-
S at all) these rims were fitted as original equipment, but the 16’’
lattice wheels look basically the same as the 15’’ ones, except for
a lip that protrudes where the rim fits the tire. Same OEM, called
JML or similar. I saw these wheels at:
No affiliation. You can see a picture there, and I have better ones
that I can send you off-list if you wish.

Those could possibly be the 16" by 7 wheel fitted to XJ81s. They were fitted
to the 93 UK models and early 94 US models. Basically a 16" version of the
earlier XJS lattice style wheel.
I dont think a 7" width would necessitate major fender work, but I am not a
wheel fit expert. They will fit all 94 XJ40s , which all came with 16"
wheels as far as I know. 15" being discontinued in 93. They look the same as
those fitted to XJS but I do not know if they are built the same.

As an owner of a set of 16" Lattice alloys I can say without
reservation that yes, they do exist:) I could even dig up a P/N if
you want.
They were offered on 1993-'94 XJ40 V12 models and probably on XJS of
the same period. They will bolt straight on no problem as the bolt
pattern is the same and there’s enough clearance; been there etc…
The original poster and I went into some depth and finally determined that
the 8 inch wide 16 inch lattice wheel was offered on UK XJ12s as standard
and possibly the XJ6 and other variants as an option, and possibly those
cars in the rest of the world, but not US cars. In the US the wheel was a 7
inch wide 16 inch lattice.
We did not come across any information that could confirm that they were
installed on XJS. The vendor in question claimed they were and XJ40 wheel
( correct) but from 1991 model year ( doubtful). At any rate they are indeed
original to non US cars.

Daniel,
As I already told you privately, you were the ‘‘Sherlock Holmes’’ and
I was just the ‘‘Watson’’
Anyway, just a little correction for the sake of truth. The vendor
said the cast letters indicated they were manufactured in March 91.
This necessarily doesn’t mean were fitted THAT SAME MONTH in a car,
only in a car of that month or of later production, though I don’t
beleive too much later…

mine are 8" wide. The part# is MMB6115AA (7" wide is MHB6115AA btw).
Oddly enough the specified tyre size is 255/55/16 P6000 for the 8"
rim and 255/60/16 P4000 for the 7" rim. However I think the “255”
part is a typo, as mine are fitted with 225 and so are the 16"
“20-spoke” wheels that came off a '94 XJ81 recently.

Here comes new arguiing
The wheels I found for sale have another parts number casted in the
back side: CBC 9643 and bear the March ‘91 manufacturing date and
are for sure 16’’ by 8’’ (not 7’').
Anyone got info on them? Greg of CW?

Don’t know how difficult it is for your to import such wheels, but
apparently in UK the 8’’ wide ones are not THAT difficult to obtain.
At least in the www site I mentioned yesterday. I got very kind and
quick answers from a guy called Steve too.

Thanks Daniel.
So my search is now narrowed to 16 inch diameter, 7 inch wide in order to
find something locally here in the US. Good info.
Steve S.
That CBC-9643 number is a old part number, now superseded to the MMB-6115AA.
And one would assume it is also 8J x 16 size.
It seems to have been the wheel’s part number when initially used on the
Sportspak XJ40s. The catalog says "after (v)629286 up to (v)667828 and
indicates these wheels were not used in USA, Canada, Korea, or Australia
(which makes sense to me as the Sportspak option was not offered in the US
AFAIK).

That seems to corroborate what we know so far, that the 8" wide wheel was
not used in the US or Canada, that it was fitted to special XJ40s only ( ie
XJ12 and I guess sportspak XJ40s).
The XJ12s in the US were supposedly fitted with sports pak suspension, but
definitely have 7" wide wheels.

Bryan,
Very interesting info! Tks. Can you pls indicate what brand/model
of tyres you’re using? I was advised by another list member that
different brands of same size tires can vary a lot in width,
depending on the sidewall protection/projections that these might
have.
Besides, what profile is your tyre? /50 /55? Pls list full size.
