Help with new tires!!!!!
I have a 2011 f150 4x4 screw with 3.73 gears. It currently has stock 275/60/r18's 31'' tires on it now. My plan is to put a new set of toyo open county at ll's in size 275/65/r18's 32'' tires on the truck shortly. I will be keeping truck suspension stock. From what i have read i should have no problems with rubbing. My question is will i a notice a difference in power when i put the new tires on and how can i calibrate the truck to the new tires?
Thanks

I am getting ready to get new tires also and searched the forums on tires and sizes. From the threads I have read you should not have an issue with that small of a bump up. Any more and you will notice a drag at start and mileage drop. I was going to go with the Toyo's but I feel they are overpriced for what they are. However I am going with the 275/60/20. I am going to give the Falken Wildpeak ATW3's a try. Can not beat the price.

I run Toyo's on my truck and like them.
As far as the OP's questions:
You shouldn't rub at all with that size. In fact, I would suggest going up to a 285/65/18 that measures out to 32.5". These would be about 1/2" wider and 1 1/2" taller than stock. It would be an overall difference of 4.87% in diameter. So, your 3.73 gearing would then be equivalent to 3.55 which is what a huge demographic of F150's come with stock.
Your fuel mileage would change a bit but likely not too much.
As far as calibrating the speedometer, go with the Hypertech unit and tune it in using a GPS. I did that with mine and it's dead on

I hate to ask for the cheaper version but what would be the cheaper version of the programmer or should i really get a good one? What would the benefit be of getting a good programmer compared to the cheap one just to change tire size and speedo calibration?

I don't want to hijack this thread, but I'm shopping for tires too. I'm planning on doing a 4" lift with some Nitto Trail Grapplers 295 / 60R20. I have 3.55 gears....How bad do you think it will change my mileage and performance? I'm already tuned, so that should help a bit.
