Olek,
As I told before (check below on the forum) for the first time I do plan to update all my BRDM series with a new RUBBER (full picture) wheels (Wheels are ready, while new moulds for other parts are still in progress).
As long as those wheels works for BTR-60 and BTR-70 then it's a good idea.
Hope that one day You will see lovely armored vehicles

(remember I didn't say when!)
Sincerely, Alexey.
