OK< here we go again! This is my first gas truck in quite some time after owning diesels... so here we go.

My 2010 F250 V-10, 4.10 gears came with 245/75/17 wheels and tires. I switched to 33/12.50/18's and the performalce is simply lacking, especially when I tow! Now, I am not sure of the weight of the stock tires, but the Toyo M/T's weigh in at a whopping 75lbs per tire, not including the wheel. So, my question, could this tire just be too heavy for towing (rolling resistance) or do I just need to get used to the lack of torque from going back to a gas motor???

tia in advance for the help!
