TIme to replace tires... Radial or Bias?
So, two summers and OEM tires are shot, worn out on the inside. Likely due to inadequate pressure (my fault I know) In searching replacements and looking at the load rating, I'm a little shocked. ...

I would recommend going radial for the sheer increase in gas mileage due to lower rolling resistance of radial tires. When the bias ply tires on my 2007 TT needed replacing, I went radial, and mileage jumped from 13 mpg to 16 mpg average. That's a 23% bump.
And for what it is worth, I'm not a bit surprised the manufacturer would put on absolutely the cheapest tires he could get his hands on, even if those were barely rated adequate for the load. Remember, they can charge you extra for the trailer if it has a microwave, or TV, or full-size queen bed. But getting a couple bucks extra out of you for tires . . . well, you gotta have tires anyway.
hmmmm I never thought about the mileage difference. Though I'm sure if I actually kept air in the damn things they might roll a little easier too. lol
That's a fascinating factoid about the rolling resistance/extra gas mileage difference between radial and bias-ply tires...I'd be most interested to see any independent links supporting it. 23% is HUGE!
