It may seem this is in wrong topic, but here's my question. I pull a 16/5 ft astro-glass w/ 115 with a S-10 pickup and on some ramps it spins way to much when trying to pull boat out. It has 175/65/r15 tires, I need some with more "grip", any recommendations on a good size that would have more traction pulling the boat out of the water? Does great when ramp isn't soaking wet or its a good ramp, but if it has rocks ect its a pain, any suggestions? Need boat tires too, but one thing at a time. lol If its in wrong, please move.
