Re: Custom Wheels and Tires Assitance for my 2007 FJ Cruiser
Rsivley is not correct about running 10.5" wide tires requiring a spacer. A 265 width tire (oem size) is 265mm wide = 10.81" wide. You can run a 285 width tire with the stock OEM wheels (basically what you have on there now) and not need new wheels or wheel spacers.
If you want to go with a 33" tire, you would run 285/75R16 with 16" wheels or 285/70R17 with 17" wheels. These are close to 33" tall. Manufacturer's specs vary. Here is how to determine tire diameter. For example a 285/70R17 means it is 285mm wide or 11.22". The 70 part of the designation means the sidewall height is 70% of the width or (11.22*70% = 7.85"). So to get diameter, you have two sidewall heights plus the rim width or (7.85" + 7.85" + 17.00" =32.7").
While some people can get away with 285/70R17 without a lift, i would recommend a 1-3" lift. I think you can run a 275/70R17 without a lift.
When it comes to lifts, sky is the limit. Cheapest is spacers, then it moves up from there for new springs, replacement coil over shocks etc. If you are going to do a lift the right way, i would say you are going to have at least $800+ in the lift (if you install it yourself). Do lots of searching here and read up about lifts, tires and wheels before you commit so you dont have to spend more money later redoing it. I can tell you my opinions and choices evolved over several months and varied quite a bit from my initial thinking.
