i just got done replacing stock tires (P-rated 275/65r18) on my newly purchased '11 XLT scab w/Duratracs LT(E) same size at local Discount Tire. These have a max limit psi of 80 and after doing some research here & online i've concluded that i should run 'em around 45psi (even though the DT guys only set 'em to the door sticker number of 35psi). I totally forgot to ask them about my TPMS (re: reset ?) and to be honest, i'm more confident in the opinions of this forums' users than those of the DT guys...ftr i don't currently haul/tow/offroad so almost all driving is road,in the upper midwest. So, my question is, do i need to hit my local Ford dealership to have them reset the tpms sensors ?

Yes 45 is a good psi, your DT guys should have set it there but if you take it back they can set your air and set your TPMS to look for 45psi instead of 35. If you take it to the dealer you will likely have to wait an hour or more for a 5-10 minute job.
