Hello,
I have a 1050D under restoration.

I need new tires. I have car tires today (215/75-15) and I want to change to tractor tires. Which sizes do I need?

I havet seen pictures of 27-8.5-15 but I have also read that it should have 6.5-15 (rear).

Thankful for any help I can get. Sorry for not writing in German but I don't remember much of it from school.
