S637 on Fifth wheel RV
Got these tires about 3 years ago for our 32 foot fifth wheel and they are great. The tire sidewalls are super tough and the tires weigh more than other trailer tires that we have used in the past. When we need another set of tires, I will get some more S637's and take the old tires and put them on my flatbed trailer for farm use. On this trailer, they should last forever.

Peace of mind for our 5th wheel
Got these to replace an older lighter set that came on our Montana 5th wheel. Only took one trip so far, around 1800 miles round trip. Didn't have any issues at all and our pressures and temps were stable the entire time even in the 90 degree Florida weather. No complaints at all, they have performed well for us so far.

Best tires we have found to put on our camper!!
These tires run flat across the tread and do not round off the corners like the usual tires that come on camper. Being a heavier ply they hold up under the weight.
