Not sure if this should be in the Trailer section or not, but Do yourself a favor & check your trailer tires. Yesterday while heading to the lake I heard A strange slapping sound. It was changing with speed so it had to be a tire, I thought it may be a rock in the tread or something like that. I have All Terrain tires & they always pick up little stones in between the treads. Anyway, it started to really bother me so I pulled over to take a look. Most of the tread section on one of the trailer tires was hanging off, I'd say about 4", & it was just slapping around. I was basically riding on the cords, stupid me does not have a spare so I limped it to the launch area. It was only about another mile & the speed limit is 30 mph on that road. I dropped the trailer & headed to Wal-Mart, only because last week I noticed they had tires on nice rims for $70, just bolt them up. I grabbed two of them & back to the lake. Now I do have a spare because the other old tire looked pretty decent. I just thank God that this didn't happen when coming back from the other "big" lake, that's all highway @ 65 mph or better pending traffic. I know you should not have a single axle boat trailer over 55 mph, but on that stretch of road you will be run over if your not up to traffic's speed, whatever it may be. Anyway, just wanted to pass on my "close call" of the week. Check your tires.
