Bought brand new 2012 Kubota
M7040 and asked for it to come with industrial tires which were provided by Kubota Canada.
MITAS made from some "behind the iron curtain," country.
No info on sidewall about max pressure to set bead, ....
Next I ordered a very expensive set of TRYGG studded chains which are designed to be installed with no fitting required.
Chains came and were too long.
TRYGG asked me to measure the diameter of the new tires installed on my new tractor.
Trygg provided the tire dimension data used world wide by the Tire and Rim Association.
My new tires were 3" smaller in diameter than the industry standard which meant my chains were about 10" too long.
Kubota Canada would not even talk to me about this and the dealer was powerless.
TRYGG is a great company and had me ship the chains to their Canadian distributor/factory and they were rebuilt to fit my undersized tires. Free.
Now the rear tires are cracking like they had been in the sun for 20+ years.
I never thought a company like Kubota would put junk tires on a new machine but clearly they did.
Before I bought my new tractor, I had a Nuffield 465 for about 30 years. The name brand tires I bought after getting this well used tractor stood up for all of the 30 years.
You can buy low priced tires and get what you paid for. Short life. Don't leave the tractor in the sun but indoors.
Even on a new tractor be very wary about what you are getting on your new tractor.
