Default 2009 XJ8 Portfolio - Downsize the rims?

Beautiful car, but . . .

Yes, the Selena wheel rims are beautiful, but they don't like my potholed city. Low profile rims don't give me enough rubber between me and the road, and I spend a fortune having them regularly realigned, repainted, etc. Replacements are almost unavailable, and even if they are, they cost about $1,600 a pop. [The last time I bought 2, I had one shipped from the UK and the other from Atlanta, and was told I had the last 2 in the world.]

So I want to get them back to pristine condition and mothball them. I'd like to use a Coventry wheel and downsize to get more tire. Has anybody done this? Is there any reason I can't get 19" wheels and tires for this vehicle? What would the correct offset be?

Any advice is welcome!

Kevin

Hello Fozard ,

My wheels are the Performance 19 inch ( standard on XJ8L ) but I am thinking of going to 18 inch for the very same reason , more rubber between the wheel and road .

Sepang wheels are 9 inch wide with an offset of 49

Coventry make a wheel called the " Whitley " it's also 15 spoke
there are two sizes available in 19 inch

19 x 8.5 with 42 offset
19 x 9.5 with 25 offset

The 19 x 8.5 inch is the closest to the Sepang wheel size

Hope this helps

Sid

There are a few 18" OEM rims that will fit the X350.

The first X350 Super V8's had 18's (2003/2004)

Also the XF, X150 XK, X351 XJ and F-Type 18's will fit.

But be careful with the staggered wheels from those models, you need a set of four "front" wheels, the rears are wider and with the X150 XK the offset is wrong.

I went with the Tucana 18 wheel and Michelin Pilots. Attached are your Jaguar options.

Smaller wheels and taller tires are a move in the right direction, but PGH and surrounds will still tear the living s**t out of your suspension even so.

For those who haven't had the pleasure ... Pittsburgh's road-shaped-objects are none too kind even to the underpinnings of right stout pickup trucks. Processed so as to align the potholes jest right, they could be sold as pre-fab deep bores for oil-wells.

No further drilling required.



Best advice I can offer is to get some other vehicle for commuting, (Buick's M18 "Hellcat" would be a good fit .. if one could get away with it..) save the Jag for "get outta town" and long trips.

I downsized from 20 Sepang to 18" Tucana. Much better !! There was actually a 17" available on the earlier cars.

ACK. Allowed taller-sidewall tires to give earlier VDP a softer ride.

Those should be a fit for the likes of my 2005 'base' XJ8-L, but the SC models had bigger brakes, did they not?

Rather unlikely they' d clear the calipers and such....

Default 2009 XJ8 Portfolio - Downsize the rims?

Had success fitting 18 inch dynamics over the brembos on 05 super v8.

Did not prefer the look, though they did fit.

Likewise I ran 18" Venus off an XF/XK on my Brembo-equipped XJR, didn't like the look, but it worked.

OK - looks quite aside ... 18" works on 2005 XJR and 2005 Super V8.. two questions remain though...

A) Will 17" fit both of those?

and

B) Will 17" (or even 18") fit Kevin's later (2009) Portfolio?

Someone out there in radioland already knows the answer, but I am not (s)he.

The supercharged cars have bigger brakes (Brembo in the earlier models, Teves on the later) but either way 18" is the smallest you could go.

Cambo is correct, however, just for reference, 17 wheels fit the rears on my Brembo SV8-just.

I have Whitleys in 18"s on my car. I thought about going with 19"s but am glad I kept with the higher sidewall for ride compliance.

Well, thank you to everyone for the very helpful advice (especially Sean for that detailed attachment). I am now more confident about downsizing, and I'm sure the extra rubber will help the poor car to survive the local roads! My pocket book may cause a delay here, but I will post an update when I have finished the change! Torrid, I think that those Whitleys look very smart. It's great to see a picture of them on the car. Thermite, I'm fond of your home town which is now my home, but will never get quite used to the climate and the roads! I have actually bought an elderly awd for those days when it's -20 outside and the city forgets to plow the streets (the Portfolio is spectacularly uncontrollable down some of our steep hills in such conditions) but there's no point in having such a beauty as this if you're only going to keep it for 'Sunday Best' - life's too short and I want to drive it as much as I can!

Thanks again, everyone.

Kevin

I got a set of wheels from here:
http://www.nicheroadwheels.com/sport-series-c-1772.htm


If you shop around you can get 4 wheels for about $800. They also have better wheels and custom wheels for about the same price as OEM. I'm thinking about getting another set of wheels from them in 18 or 19 to get a better ride than the 20s.


Also, I found that Ford Focus ST's have the same size wheels in 18", so there is another option out there too.

They are plowing the streets now? Must have gotten hands into Federal funds. Go figure..

PGH - too-often ugly as only cubic miles of poorly-maintained 1880's brick structures on bad pavement can be - *is* a place centrally located near to lovely scenery on 'interesting' 2-lane blacktop that a Jaguar can love. Western and Northern PA, much of WBGVA, lots of MD, and Western NY State on up into New-Ink Land or Canada.

But your AWD? Here's a more local acid test:

Seek out 'Cutler Street' over on the Northside, 15214, just 'round the corner from our old home (now bare ground again..) on Chester Avenue.

Best 'tires' to navigate its cobbled slope are probably Swiss rock climber boots ....on healthy feet, strong legs, good lungs, and an unimpaired sense of balance. Using the adjacent 'sidewalk' - a staircase, actually - is cheating.

Take a camera.

The 'street' could be mistaken for a retaining wall. Even in Hong Kong or parts of italy.

Although it's taken ages, I wanted to put a closing note on this thread. Thanks again to all who chimed in. I live in Pennsylvania, and the testing station I sometimes use, and the dealer, both told me that I would fail my annual 'stickers' test if I put 19" wheels on the vehicle, since the door jamb information only specifies 20" wheels. In Pennsylvania if you go to a (legit!) testing station, they must fail you under the rules.

I now have one clean set of the original Selenas in a rack in the garage, and a new set of 20" Coventry Whitleys on the vehicle. They look very handsome. I can 'afford' to hit a pothole and lose a $300 rim now, but I still plan to keep the car off the road during the winter!

Just went over 30,000 miles, and I still get a lot of admiring comments on this beautiful 'last of the breed'.

Kevin

OK, so would these 17" wheels fit my 06 SV8 or not?


17" Axis Sport wheels and tires


The seller has a listing of what vehicles the wheels are supposed to fit that includes "2006 2006 Jaguar XJ8 (Super V8) Jaguar XJ8 35 to 45 63.40 63.40 12x1.5" He says the bought them from a neighbor who had them on a Jaguar but he wasn't sure which model and that the wheels and tires were purchased in a package from the Tire rack. Tire rack only lists 19" and 20" wheels for my SV8 so it may be the same thing as the inspection limitations for them.

I would consider these for my 2006 Jaguar Super V8 even though the diameter is 26.3” VS the OEM 255/40R19 tires 27” diameter because I am assuming 17” tires with more side wall might give a little softer ride than the 19”. Tire rack has these tires new for $107.45 each or $430 a set. The seller said he could take $850 for the wheels and tires.

No they will not. You need 18" to clear the front brakes.
