I am sure this has been brought up in the past, and likely there is no simple answer. But is there a website one can cross reference wheel sizes etc and offsets?

The modern ones are all 5 x120. But I am worried about offset etc?

Thanks for any direction.

 

I use this web site:

https://www.wheel-size.com/size/land-rover/defender/

 

The offset is the reason the Range Rover wheels won't fit. Couldn't use my 19" LR4 winter wheels either, since they have an offset of 53. (Defender offset is 41.5)

 

beside the example below actually most range rover wheels will fit. If you have a p400 or v8 you will have to go with a 19 or larger wheel to ensure the brake calipers clear

make sure the offset stays in a similar range. i know the range rover sport svr wheels fit and look great.
