I have a standard 3.0cdti signum with standard wheels and 215/50/17 /91w tyres on, will I be able to fit 225/50/17 onto the origional rim?
Many thanks!

this thread should answer any questions..

There seems to be a lot of debate as to whether the 3.0 V6 CDTi should be fitted with Extra Load tyres (as it does from the factory). 91W are Standard load. Have a read of this: http://forum.vectra-c.com/showthread.php?t=25832
Hey,
Cool thanks for the links guys.
I'm going for some 225-45-17 rated at 98w (Pirelli pzero) so looks like they should be ok!
Cheers!

Deffo be ok with them at 98W, not sure about 225/50's though. usually go for 225/45....
There have been loads of threads on this very subject, might be worth a search....
The "50" part is actually a percentage of the width I belive and is not an actual measurement in mm. Going for 225/50's would throw your speedo out too much. 225/45 keeps the diameter of the tyre as close to the original as possible.

hes on 17's - isnt 50 the std ratio ?
Not if you go to 225's it isnt. You have to drop the profile to 45's to keep a similar tyre diameter
They should be fine. I believe you'd also be fine with 95 load rating on 17s. 225/50/17 is not a profile recommended by Vx, so best not to for insurance purposes. Also a 225/50 would have an even bigger sidewall than a 215/50 as the 50 is a percentage of the width of the tire - your handling would suffer a bit due to the larger sidewall. With 225/45 you'll find a much greater choice of tyres available and also a bit cheaper as it's a much more common size.

hehe sorry I think peeps read by thread before I edited it!
I will be going for 225-45, I called black tyres who suggested that changing the ratio would mean my car would spit the gearbox out the back as it was changing the rolling radius to much, so I had a little chuckle at that rather extreme response!!!
I'll be ordering some 225-45's online later!
