should have posted in the freelander section, but for what it's worth, if you searched, you would then know the following:
1) preferable to replace all 4 at the same time
2) worst case replace 2 on the same axle
3) ALWAYS fit the new ones on the back
This will go a long way to avoiding any of the VCU/ IRD issues that can be caused by fitting new tyres to the front only.
If you need more information, please search, there is loads and loads, what I have put above are the facts based on what has been written many many times. The info is all here.
