Specs:

16x8"
4 9/16" back spacing
6/5.5 bolt pattern

I chose to go with 8" wheels for two reasons: For a bit wider tire footprint, and to fill out the area under the flares to get rid of the sucked in look. Here's a picture showing how the tires sit in relation to the flare. Sorry, I don't have a picture with a 7" wheel for comparison. The main reson I went with aftermarket wheels was to get a matching spare out back to eliminate the ugly black OEM one facing traffic.

I did, however, have to add 1/4" spacers in the front to clear the brake calipers. You might be able to get away without using spacers for this amount of backspacing, but you would definitely need to grind the calipers down a bit. I wasn't ready to do that, so I had custom spacers made at a machine shop using a local friend's design which he has been using for a few years without any issues on his '98 4Runner. I went custom because these are better than a standard spacer. I also purchased rear Toyota lugs and installed them in the front to allow more threads to be seated. I realize spacers are usually looked down upon, but they've worked for the other gentleman and they've worked for myself just fine to this point.

There is a significant amount of additional rubbing in the front wheel wells using the 8" wheel with 285's compared to the 7" OEM wheels. I have trimmed off a section of the plastic fender lining, but still have yet to grind down the body seam that is directly behind. I've still done a pretty good amount of wheeling as is, but the grinding really needs to be done.

These wheels are also offered in 3 5/8" back spacing, but that would have induced even more additional rubbing, which is why I elected to go with 4 9/16".

FYI: I am keeping my OEM wheels for the time being and am not currently interested in parting with them. I've received a number of email inquiries about selling them, that if I ever decide to do so, I should be able to find a home for them.
