I put six of Hercules H902s 275/70R22.5 on our new to us 06 Safari Cheetah 40PMT and they ride nice. The GoodYears it came with were 10 years old, but had only 15,000 miles on them, sad to see them go but we didn't want to risk it. I have 110 psi and use the balance beads (never heard of them before) and it's a smooth ride. GO for it.
