[This review was collected as part of a promotion.] Heavy duty tire.

Vast improvement over the regular tires Ive been buying.

We pull a trailer over 10,000 pounds. Before we discovered the Greenball Towmaster ASC Load Range F tires we had numerous blowouts on our travel trailer. One blowout, the tire cut through the floor of our travel trailer & required a lot of repair. Our most recent set of these we installed in 2017. We have never had an issue after we installed these. We plan to buy another set this year. All Steel Construction... Steel in tread & sidewall. Highly recommend these trailer tires.

Installed these Greenball ST225/75/15 Tires on my 38 Foot / 11,000 pound Travel Trailer after the OEM (Keystone) installed "Hi - Spec" Tires started to blister on the side wall after just two years and 7,000 miles of use. Just looking at the Greenball tires reveal the stoutness of the side walls and do weigh considerably more than the poorly manufactured tires installed by the OEM. Hopefully, these new tires will last the normal five to six years of normal operation with no issues and if so, we will purchase another set.
