I had planned on replacing our 2010 date code Load-Star 12” 5.30-C bias-ply tires with radials and moving the bias-plys to our utility trailer at the end of the season. But as luck would have it the 12” 4.80-B tires on the utility trailer had dry rotted and lost air after 11 years. So I jumped on a set of 3 Radial Velocity TR088 ST145R12 D/8PR from Giga-Tires.com for $93.00USD and moved the old Pop-Up tires to the 4x6 utility trailer. There was plenty of clearance and they should be fine for a few more years. I had the new tires mounted at my local Costco for $14 each which included balancing and Nitrogen. I never balanced trailer tires before but since it was included how could I say no. Not being familiar with this brand and the lack of reviews I’ll be rolling the dice when the Pop-Up hits the road next month. Wish me luck and I’ll let you all know how they do.
