Guess I.ll put my 2cents whorth in.This spring bought a 2 year old Wildwood 29 foot tt.Previous owner had bought it new 2 years ago,towed it to florida,parked it for two years and towed it back to Michigan.Chinese 6 ply tires looked great.First trip for us we went 200 miles to northern michigan.30 miles into return trip rr tire blew.Pressure was checked before we left up north.Luckily only minor damage to the plastic covering underneath.Got home bought 4 new Goodyear endurance 8 ply tires.Feel much better about tires and the trailer sways less. Btw,Tomman,I,m one of your retired brothers.
