I would like to replace my regular tires with "low pressure" tires and rims to allow me to launch boat on sandy beach. I understand that wide low pressure tires won't sink as far into the sand and hope this will allow me to use ATV to move trailer. Trailer is Eagle for 18 ft. Wellcraft. The trailer would not be used on road or at speeds greater than a few mph when these tires are used.<br /><br />Any experience/ideas and where to locate tires and rims in Ontario, Canada would be appreciated.<br /><br />thanks
