2010 PreRunner 2x4 tires, wheels, RE_Gear?

Hi, I have a 2010 4cyl 5speed Tacoma 2x4 prerunner that is 6 lug.
The Factory tires on my truck are...245 75/16

Got some, 18" wheels with duratrac tires 275 70/18, from friend. This rim package was on his 4x4 2013 taco.

Was looking to install: 18" wheels with Duratrac. I have a 3" lift with Bilstiens 5100 front and AAL in the back.

My questions is:
Will my 4cyl be able to handle the big tires?
Do I have a 4.10 rear end? Should I consider re gearing to 4.56?
Anyone who has this combination on there 4cyl, how will my acceleration be effected by the bigger tires?

I do not do any heavy off roading, usually just driving around city and general commuting, occasionally hauling a car dolly (1000lbs), and very light off road.

Any input will be appreciated.
