So Im putting either 285's or 305's MTs on my 2005 trd that has a 3" lift. I know already that Im going to have to get wheel spacers to have enough room to fit them on and I know that I can fit the 285's on but my questions are can I fit 305's if I get a wider spacer and my friend whose a mechanic said it might effect the way the truck runs or something because of different sensors on the motor from going from a 31" tire to about a 33" but he wasn't sure. If any one has these size tires and knows anything about it please let me know so I can get the right tire. I basicly want the biggest tires I can fit without lifting it more and without it rubbing tooo too bad (I can deal with a little). I also have been going through ball joints like a ma f'er for some reason. The ball joints themselves don't go but I keep ripping the boots open and then same thing with my inner cv's. I do do quite a bit of off roading and my friend said becasue its IFS and lift and its too much for them. I didn't know if this was BS or if its not BS if there was anything I could do like heavy duty ball joints or something. Any input appreciated!
