Looking to put on bigger tires

Hi, I have a 2008 Tacoma and I recently installed the Rancho quick lift shocks, they advertise that I can increase two tire sizes. The original size is 245,75,16. Is 265,75,16 two sizes bigger? And if so has anyone put the 265,75,16 on their factory toyota rims? And did the 265's fit on and clear? My concern is the clearance between the tire side wall and the upper A arm/upper ball joint area. There just dosn't look like much room and the 265's are just under a inch widder. I'm afraid they will hit the upper A arm. Dose any one have any experience with this or any suggestions?

 

They will fit , depends on the lift you may need to take off the front mud flaps.

 

Agree they should fit fine!i have 285 75 16 and did minor trimming and mud flap removal. Also bmc just to be on the safe side.
