Replacement Tires

So I need to replace all 4 tires on my 5th wheel due to cracking sidewalls. The size on it currently is ST205/70R14. This size is a bear to find and are quite pricey. I'm looking at going with ST205/75R14. I'm pretty sure I have room for them. Any thoughts on Radial vs Bias plys? Anyone know of a cheap source for trailer tires?

The 5th wheel is only a 21'. The current tires are BF Goodrich Lifesaver Radial ST. Load Range C. When I look at the tires now I know for sure I would have plenty of room for the 75 series. It would also help with my nose high attitude when hooked up.

If you'll provide a little more info, we'll try to help. Look at the side of the tires. What load range are they? I would imagine load range "C" or "D". Also let us know the maximum weight and tire pressure listed on the side of the tires.

Those are very small tires for a 5th wheel. What size trailer do you have? What brand tires are you replacing?
