Find some take offs
As above, the search function is where to find the answers.
I note that you did not say if it was 18" or 19" rims and I assume summer type road conditions only. As such, as long as the tyres are XL rated, pretty much anything will be OK, particularly if they were take offs.
The current "summer" tyre that Land Rover is putting on as OEM is the Michelin Latitude Tour HP 111V XL. I noted a set of four 19" takeoffs on eBay awhile back for a thousand dollars.
