That's a significant issue for me. My 16s in Maxxis ST have a load capacity of 3,420 lbs. but the equivalent XPS Rib is 3,042 lbs.
That's significant for me in 2 ways:
1) My trailer axles are carrying 12,280 lbs. Ballpark, that is 3,070 pounds per tire if I assume that both sides of the axle are carrying the same weights. I know both of my axles are carrying essentially the same load (+/- 40 pounds) from a prior weighing.
2) My trailer's axles are very close to each other. Between my tires is only 1" to 1 1/2". I'd be afraid of going up a tire size and having rubbing issues.
3) It's a significant cost to change wheels AND tires. Tires were bad enough. The STs seem to be performing well.
