Quick update...
Seems that once I signed on the bottom line, the need to keep me informed was thrown out the window. After waiting a week and getting no update when my tractor was due (my tractor is in stock), I rang to find out. I was told they had to send to Australia for the Industrial tyres - even though they still hadn't told me the brand and rating - something I had specifically asked for before they were fitted.
I now have discovered the industrial tyres on their way are only 6-ply, which I think is too little.
One of the other company's quoted me a set that were 12-ply rated. This seems more more realistic and their price was half what I have paid. Unfortunately, I have to go with the company I purchased the tractor from so I don't have to pay for two sets of rims.
My Ag tyres on my current machine are only 6 ply and they are definitely under-rated for the loader work. At times it seems like they are going to roll off the rim!
What do you guys think??
