Greatest tires ever
Seller Verified Purchase
I bought these tires for my trailer for a 20" Fourwinns Wake Boat; they are perfect. Would recommend these to anyone needing trailer tires. Boat is approx 6,000lbs.
Seller Verified Purchase
Trailer Tires and Mower tires is what I buy. Always a great deal and very happy with my tires. Alot cheaper than going to tire store, about half the cost.
