Ah I gotcha. Although it couldnt be any worse than with stock tires, heh.
Will there be a noticable loss in torque with just 29" tires? As I said, going through deep sand tended to want to bog the engine down. Taller tires would lower torque output, although being taller they would more easily "glide" over the sand instead of push through it. And, being a little wider they would sink even less deeply.
So, will I see such benefits using taller tires?
