I've got a 253 and I plan to put a loader on it. If I assume half the tractor weight is on the front end that's about 2100lbs, and add the estimated weight of the loader at 750lbs that's 2850. The load capacity of most 6.00-16 tires is around 1500lbs so X 2 and you get 3000lbs. So my loader is capable of lifting 150lbs before I hit the limit imposed by the tires. I've had other tractors with loaders and have always ignored this problem and have been fortunate to never have a blowout. I know the factory offers a variety of wheels, I currently have 4.5-16s. They also offer an 8-16 wheel and a similar width in a 15". Can you all steer me, no pun intended, down the right path to choosing the correct wheels and tires to alleviate this problem? Or should I do what I have always done and just ignore the math?
