I suspect the answer is Yes.
I had assumed Asteroids are off X300s, but I see from the "tramlining" thread that everyone is discussing 17" tyres on XJRs.
I have a set of reparable but damaged Asteroids with 18 x 255/40 tyres sitting in the man-shed, not mine but on "appro" from the dismantlers.
I can buy them and send them to be fixed, but no point if offsets etc, are all wrong for the X300
Will they fit?
thanks

 

They're originally off the X308 XJR (they were optional). They fit and they look great, but I wouldn't want them on my car - I prefer the way mine drives on 16" wheels to the 17"s that were on it when I got it...

 

thanks Ziggy
I finally got the Asteroids into a local wheel guy today who says he can straighten them
They are 18" of X308 and I want to put them on X300 - is that OK to do?
I assume offsets are the same - is X308 suspension almost the same as X300? I thought the main change in 300 to 308 was the move to a V8 engine..

 

FWIW I have X308 wheels on my X300. In my case they're the standard XJ8 wheels.

They fit fine *except* at the front, where the wheel center holes foul the wheel bearing dust caps.

I very artfully reshaped the contour of the dust caps. With a hammer and drift

All's well.

Not sure if you have the same problem with the wheels you've mentioned.
