looking to upgrade worn Michelin Primacy tyres 225.55R16 on Performance old school mags to 17 x 7 rims with more of a star pattern similar to XJ13 rims. What other marques have the same 5 stud pattern. I believe I need 5/120.6.
I think BMW and if in Australia Holden have that bolt pattern?
The 5 stud pattern is common, the offset is not. Youāll need to shop carefully to find non-Jaguar wheels that will locate properly in the wheel wells.
Additionally, the Jag hubs require a larger-than-typical center hole. I think some BMW wheels have a large enough center hole but I donāt know which ones specifically.
I once had a machine shop enlarge the center holes on a set of aftermarket wheels for my Jag. Easy. But, might not be possible in every case.
Cheers

My understanding is that the XJS wheels are hub-centric (centered by the center hole, not by the wheel lugs)ā¦ http://www.bernardembden.com/xjs/rimtire/index.htm
ALL OEM wheels are hub-centric. Only the very worst aftermarket garbage is located by the lugs.
Agreed, but the originator of this thread is asking about wheels from other marques that have the same stud pattern; I was trying to point out that the bolt pattern is a secondary issue, the hub is the primary issue. The XJS bolt pattern matches GM wheels from the 50ās and 60ās, but the hub is different; I think later model (1997 to 2007) XK wheels do have the same hub, but the offset may be different and could cause tie-rod interference for XJS front wheels (as could wider wheels).
Here is another good reference on wheel fitment: https://www.lawheel.com/wp/category/fitment/
Best case would be for some responders to say what actually worked for them (I still use my original wheels).
Thanks for input folks. WayneC1 has nailed it, Iād prefer not to reinvent the proverbial āwheelā and prefer to take advice from real world experience.
Surely after all the years the XJS has been around, the number of adjusted race cars and boofheads like myself seeking a trickier car, someone has actually upgraded successfully. Iām all ears. Many thanks. Yes, Iām in Australia. Cheers, Dan.
only a handful of wheels were made without a center bore for hub. I bore too small can easily be bored larger at any machine shop. a larger bore is easier yet. hub centric rings are available in almost any size and dirt cheap. I paid $6.00 shipped free for a set of 4!
The convertible was bought 9 years ago with a set of wheels fitted by the PO claimed to be from a BMW.
They look OK, although the wheel nuts do not engage all the thread on the studs, a slight mismatch.
Maybe the PO got the wheels at a bargain price, otherwise you could find a set of updated Jaguar wheels.
Went through this with our E-type. A very inventive hot rodder took an axle from a Chevy, fitted a guide in each stud hole and used a valve grinding cutter to move the holes just a tiny bit to match the BMW bolt spacing. This opens up a world of BMW wheels. Unfortunately not all have the right hub hole, but many have an offset that works for Jaguars, which are kind of āfront driveā type. I think for Jaguars the ones that are closest to a ābolt onā are some 5-series from the '80ās - while others can be bored, as suggested.
When the cutter moves the holes the taper is deeper, of course, but the change is minimal.
This isnāt a trivial set up as the guide needs to match the cutter guide bore and the whole assembly must be fixtured.
We have āSuperliteā minilite clones which were originally made in Australia, now VTO imports them from China. They are for 5 bolt, 15 inch shod Corvairs!!
The 17 inch XJR6 rims will fit.
My 84 came to me w/ bolt on wire wheels. I promptly swapped them for a set of starfish XJ-S rims to match the spare in the trunk. True, it limits you to 15 inch rims. But I do like the look.

Iāve had the Australian Super Lites on my E for over ten years and the bolt pattern, 5 on 4.75, was standard on most mid sized Chevies for many years.

The āCorvairā or Superlite (now VTO) wheels are nearly the only āChevyā wheels which have enough positive offset - which is, if I recall, about ~23 mm plus. The American 5 spokes and the like for vintage Chevies and Corvettes normally donāt have enough positive offset. For a series I E-type the + 23 (or so) is for a 6 inch rim. Donāt know if a wider rim will fit at this offset. Unlike the E-types, I saw an XJ-S post somewhere that showed the clearance up in the rear wheel well with some aftermarket stuff.
BMW is 5x120 mm. Jaguar (and Chevy) is 5x4.75 inch, which is very close, 5x120.7 mm.
Some may say less than a 1 mm doesnāt matter, but this is an application where it may matter the most.
As others pointed out already, the Jaguar hub limits the choices severely. Bore size for GM wheels is 70.3 mm, while the Jaguar calls for 74.1 mm.
Unless the wheels are aftermarket and have larger bore size that requires an adaptor, no standard OE wheel will fit.
To me, the best approach to larger wheels for the XJS is the Revolver 17x8 from the early XK8:
Well, if thereās enough meat perhaps you could have a machine shop open it up. And if thereās lots of meat, perhaps you could have them cut the mounting surface back to get you the offset you need.
If you get the center bore right, I wouldnāt worry that much about the 120 vs. 120.7 hole pattern. In fact, if youāve got the thing at a machine shop anyway, you might even go ahead and elongate the lug holes by that much.
All above is true. Iād do it in a heartbeat but the machine shop rates in my area are prohibitively expensive. I will be looking at adding at least $100 per wheel for enlarging the bore size and/or fixing the bolt pattern 5x120 to 5x4.75".
Not to mention that the Jag lug nuts are the Mag-wheel style while BMW uses (typically) cone-seat bolts and to do it right, one will have to invest in a set of those tooā¦
At the same time, CL is full of ads for Jaguar wheels at bargain prices.
No, I wouldnāt do that. I wouldnāt tighten down a set of cone-style lug nuts on a circle that is 0.7mm off. Iād drill the holes out and use the mag-wheel style lug nuts.

Bought aftermarket 18 inch wheels for a late 80s Chevy Camaro. Canāt recall exact offset but as K describes, that fitment element posed the biggest challenge. Wheel shop bored hubs to correct Jag spec. for minimal $. Been good to go ever since. I will try and locate exact specs but it was done over 15 years ago. 1989 XJS
