I have to smile and yes I should have noticed this before now. I bought a 2011 Skeeter FX. I remember in the description (good tire tread). Well I focused on the boat and trailer and really didn't look at the tires after al the tread looked great. I ran through the boat and trailer with a fine tooth comb. It was a great used boat in fact looked new except for the normal wear you would expect.
So I bought it in March 2018 and fished about every weekend until I put it away mid November. I put a lot of miles on it this summer.
So I am heading on a 600 miles round trip the end of February and I finally checked the tires in detail. Lol. Two on the left side where Chinese Goodyears built 21/10. That makes them over 8 years old. I had two different brands on the right side. Carlisle built 34/12 and a Maxxis built 22/15. The spare was a Carlisle built 22/17.
What I never noticed the two Goodyear where well worn no tread on the inside.
The Carlisle looked brand new. The Maxxis was decent.
For the life of me I can't figure out why there were 4 different tires and I knew I was looking at the good tires and just never gave it a thought to take a hard look at the tires.
Well today we put 4 new ones on and since since the spare was good we kept it.
So the moral is good tread on a used boat means get down and read the dates.
Lol I'm really feeling lucky that I made the the year on the two old tires
Another thought these where Chinese tires and nothing went boom, in fact I give them credit for making 8 years.
If your asking I bought the Carlisle Radial Trail HD tires. I run them on the other trailers I have with no problems and they are abused. Another option would have been the new Goodyear tires but they rate no better than the little less expense Carlisle Radial Trail HD.
Both the old Carlisle and Goodyear did not have a great reputation.
