Tires sizes and shocks question

[BeachWagon]

I am looking to get some thoughts here. I need new shoes and they ain't cheap. I picked out some nice looking ones to choose from. I can get a set of 265/75/16 4 ply which will slide ride in and look good, or I found a set of 285/75/16 8 ply which will come to about $50 more... not bad....but..... Then I gotta add i lift if I do that. That confuses things. I have thought about throwing a spacer lift in which is easy enough, and then some spings, I have some failry new, 15,000 miles, shocks, but didnt replace the spings. There is so much on here but I like the idea of getting some upgraded Toyota parts, i.e. Tundra or Cruiser. Can anyone shed a little more light on what they would do if they were to go with the 285s, a spacer and spring set up to accomplish about 4 inches, should be enough for the tires right?
By the way, its a 2WD 1997 Limited, and is pretty much on its way to being a camping rig.

Thanks all ahead for your thoughts

Do yourself a favor and stick with the 265/75's. Going with the 285/75's will mean a lift, which to get 4" out of it would mean OME springs and 1"+ topout spacers at the very least/cheapest. THEN, you'd need new UCA's because the factory UCA can only handle up to 3" of lift before the ball joint starts to bind. Your gas mileage will decrease even more with the 285's. Not to mention you'll want an alignment no matter which tires you choose ($60+). It adds up quickly...

2wd.. get the 265's.

Thanks for the input so far. I see the point of the gas mileage and having to do the ball joints. Getting the 265s and then 2-3" spacers later on might just be the most economical way to go.
As a side note, eventually I will get around to doing the build thread on my Runner, I been taking pictures, but just haven't gotten around to organizing them so I can upload them.... this thing called working has me beat in the evenings!
