The ST718 features curbing ribs which help shield the casing from sidewall damage. Its all steel casing construction resists punctures, increases vehicle stability and contributes to more retread cycles. This tire features an application specific tread compound which resists the effects of scuffing from sharp turns and gives longer mileage. The ST718 is an excellent commercial tire rib for urban and metro fleet operations.
Bought 6 new ST718 tires for a Trek Safari 26ft RV, so far I have about 2000 miles on them, it has been great! We drove through the Apalachian Mountains in WV, Fancy Gap, VA, to FL doing 75mph occasionally, handled well including banking load in the mountains. I have the G/14 ply rating tires, supporting more weight per axle (about 350lbs). Pressures set to manufacturer recommendations, 110psi cold. Great value and fast shipping to installer by TireEasy. The customer service was responsive as well when I called for assurance. Thank you!
