Many thanks guys for the further info; I knew you would have all the answers!

I had heard that Tempest wheels were also retro fitted to Typhoons as they were of a superior build to the Typhoons original fitment, so all rings true. I did manage to uncover the rest of the text of the part number on the tailwheel tyre which revealed the part number 41-A2346 if that makes any difference. I’ve also been told the Westland whirlwind also had the same tailwheel tyre.

Still no news on the other main wheel but I’ll be sure to keep you posted. 🙂
