Im waiting to find out which one, but apparently I have a defective Senta alloy (mechanic left a message). Looking at some on ebay. Are front and rear the same size (the wheel not the tyre)?

 

Fronts are 8.5 vs rears 9.5 rim width.

 

That's not what I'm seeing in the attached. The OP doesn't list his vehicle so we can't answer for certain but also I don't see the fronts ever being 8.5"

07 - are 8" both front and rear.

The 08 and 09 show 9" front and 9.5" rear

 

 

Seen that listing before, lots of errors. Need to look at official Jaguar stuff, like Cambo did.

 

Thanks for the replies. Its a 2007 XKR. Im in mild panic because im sailing to Le Mans on Wednesday. However having done a lot of research last night I've come to the conclusion i really shouldn't look at anything but brand new wheels. I have found people who supply them very near me (Coventry, England)

 

Having just acquired the same vehicle I'm pretty sure mine are larger at the rear..I'll check later with an update

 

Note that the X150 was introduced as a 2006 model in the UK and a 2007 model in North America. Make sure that your reference materials reflect that difference.

For example, the UK 2007 is the US 2008. Also, specifications varied by market; the UK 2008 XKR-S was not available in the USA and the US 2008 and 2009 XKR Portfolio models were not available in the UK.

Why make things easy?

20" Senta wheels were optional and, unless the OP is the original owner or has the paperwork, there's no way of knowing for sure If his damaged rear wheel is 8.5" or 9.0" wide unless you measure it.

 

I replaced my sentas on my 2007 xkr, they were f/8.5x20, r/9.5x20 the et f/49, r/26

 

Been out and I've definitely got different sized tyres front and rear but I guess i really need to measure the alloys then ?, but as Stuart says depends on original paperwork etc.

 

No measuring needed. Just take the wheel off and read the size forged into the wheel, its on the backside of one of the spokes.
I bought a set on ebay last year for my US 2007 XK, which came from a US 2008 XKR, and they are the same sizes as what powerhouse posted above.

 

Are you talking about the factory model year (MY) or registration year?

 

Sorry, I thought it was as it's from JCNA Concours Rule Book – Appendix B - Tires and Wheels, Last Updated 2010, but I get the point.

 

I'm pretty sure the Senta wheels are cast aluminum alloy, not forged.

 

Model year. For example, the first production year X150 is 2006 even if that vehicle sat in the dealer's showroom in London and wasn't registered until 2007 it's still a 2006 model. 2007 was the first model year in the USA.

Yes, confusing. The 2009 MY in the UK is the 5.0L, and 4.2L in the USA.

 

If you want to split hairs the X150 started at 2006.5MY...

 

I am sure you are aware that wheels can be straightened and its rather inexpensive.

If I were putting replacement wheels back on, I would just go with the wider wheels which your car was designed for, in terms of the opening and the car looking correct.

 

I am not convinced this is true, well not according to Topix anyway unless the factory MY and the US sales MY are two different things.

B00379 is supposedly the first 'production' XK and that is a UK model but Topix still lists it as a 2007MY. Even B00001 is listed as a 2007MY car.

When cars are coming down the line in the factory they are all the same model year spec regardless of destination.

All of the first 5.0L cars seem to be listed as 2010MY regardless of market as well.

B31936 is an ex UK 5.0L XKR that is kicking around NZ somewhere that has a VIN before the official start of the face lift cars and that is listed as a 2010 MY even though it was registered in 2008.

B34253 is a 2010 US car currently on EBAY and that is also listed in Topix as a 2010MY car.

 

You're probably right, my bad. I was just trying to say its part of the wheel, so you can always find out the exact size from the wheel itself without measuring.
