Hi Paul

Thanks!

Now I know what to look out for.

 

I changed the wheel tire combo on my 1970 Mustang from a 4in. x14 to a 15x7in. wheel and tire. I was running a 215x15ln. 60 series tire. I knew that the speedo was going to read fast. I used a cell phone app that uses GPS to give an accurate speed reading. I found that it read approx. 3 mph. faster below 45 mph. At 50 mph. it was reading 5mph. faster. I didn't measure the tires before hand or try to make any calculations.

 

All very useful information, Thanks

 

My hand book reads


15" lattice 6,5 x 15 235/60 vr 15
16" Lattice 7j x 16 225/55 zr 16

 

Going back to the page I suggested earlier, using the 15" as "OEM", and the 16" as "Package 2" and using malc4d's sizes:

Suspension clearance: 100% clear (leaves even more room than OEM)
Fenders clearance: 100% clear (leaves even more room than OEM)
Wheelwells clearance: 100% clear (leaves even more room than OEM)
SPEEDOMETER: When speedometer reads 60mph (96.6km/h) actual speed will be 59.2mph (95.3km/h): 1.3% slower.

Hope this helps. I wish I could find some 16 inch lattice's, as I really like the look (though I loathe car-wash time). Modern Starfish it is.

 

The secret is to never let them get too dirty.

I use a slightly modified tooth brush to clean lattice wheels. I can do a wheel in 90 seconds. Practice, practice, practice.

But, if the dirt and brake dust is allowed to become caked-on....well...that's a different story.

Cheers

Im trying to get some 16 wheel dust covers to put behind my wires. I had 15" covers behind my lattice wheels and dust wasn't a major problem.

 

I would be very reluctant to change to 16inch, as for one thing, I'm paranoid that the bigger Wheels might spoil the look.

 

Very good advice Doug

I always give mine a quick rinse with the Power Washer after a Trip.

18" on mine, from an XK8


BB , lol

 

They look great with the 'Body Kit' but probably not on mine.

 

you have a good point there

My own correction here: My Pirelli Pzeros are not 245 tires, but rather 235's (it must be those broken neurons...). The actual Pzeros on my Revolvers are 235/50-ZR17. My bad.

Cheers,

 

Interesting, yet whenever I get to see these cars with the 15" wheels anymore, to me they seem to be a little too "fat" on the rubber, perhaps a little bit antiquated. It may be because I tend to see far more face lift cars around here with the 16" Five Spoke rims than cars with the smaller Lattice wheels. Not only that, but I'm also used to see my own 17" Pzeros on Revolvers, thus I've gotten used to the seeing XJS with lower profile tires.

Are you actually concerned about the size change itself, or may it be rather the fact that you will be putting the more modern Five Spoke face lift car wheels on your pre-facelift car and you're just not quite sure whether this amalgam won't go south on you? I have actually heard forum members here with the opinion that some wheels won't necessarily work the same on a pre-face lift car as they do on a face lift car because the subtle modernizing changes of the face lift XJS make it more receptive to more modern wheels. However, the Five Spoke wheel was designed for the XJS, so face lift or not, I think you'll love the way they'll look on your car. You can always look at picture galleries and there you'll probably find some pre-face lift car with Five Spoke wheels for your reference. In fact, I have actually seen here, in the Forum's gallery, a pre-face lift coupe with no less than the 17" Revolvers that I have on mine; I believe it is a silver coupe and, with those rims, he must have a lower profile tire for sure. Not that you're going in that direction, but it is at least a reference for you.

Cheers,

 

Hi Reinaldo

No offence intended but I just don't think the 5 Spoke Wheels would suit my pre-facelift Car as to me they just look wrong, being a mixture of Ancient and Modern design.

So unless the supply of 15 inch tyres runs absolutely dry, then I will be sticking with those on Lattice Alloys.

Having said that, I may consider putting on Chromium 5 Spoke, on my 95 XJS Celebration Convertible, in order that I can fully achieve the Celebration 'look'

Although the Wheels on this Car, were the alternative option of dished Alloys, which I also think suit the look of the 'Face Lift'

 

No, no offense at all, OB. It turns out that you, yourself, agree with the opinions I've heard about possible mismatches with wheels and cars from a different period. I actually don't remember ever seen a pre-face lift XJS with the Five Spoke wheels on it, even when I've seen all kinds of wheels on pictures of pre-face lift cars. I have even seen several pre-face lift cars with the Revolver wheels, yet not seen one with the 5-Spoke ones. Hmm, now I'm curious and I'll do a little research.

Cheers,

 

Pre-face lift XJS' with 5 spoke wheels are rare, yet you find a large number of them with very modern looking wheels.

I saw two pre-face lift cars with 5-spokes wheels, of which one has the TWR kit on it. Funny that there seem to be more pre-face lift estates with 5-spoke wheels rather than cars. For you to compare, I'm attaching pics of two cars and two Estates with these wheels. I absolutely respect your opinion and I only want to mention that I do find that these pictures do not show any bad mixture of Ancient and Modern that I can see, but more pictures help by giving you more info regarding your kitty's potential future looks.

And, just for your reference, I'm also attaching a beautiful dark blue pre-face lift coupe with the XK8 17" Revolvers and this one, too, looks really nice with no conflict of old and new, really, and not really different from what my own '94 chromed ones look.

Cheers,

 

They look fantastic on a pre-facelift, depending upon the colour. Mind you, I am biased...

Not for me 'Greg' I'll stay with my 'Lattice'
