any help appreciated on this one. i can get them for around the same price.
im actually not spending a dime. the KM2s are out. i dont care about the ride. i got a 4runner to use as a truck. not as an LX470 grocery getter yuppie. so, i got dents, dings, holes, have smashed windows offroading from slamming into tree roots while in trenches, etc.... this is oriented into what will get me past my obstacle while wheeling w my buddies (one who has a 1st gen 4runner S.A. w 37's detroits f+r, and 4.7 xfer case, and no lift - he is quite unstoppable, and the other w a wrangler locked front and rear w 35km2s. so im lookni for max ground clearance. 285s just seem a little overkill width-wise
i just want to make sure the 255's are stable enough on the road.
Of course this is just my opinion.
check with brain he ran the 255's for a while and is now back to a 285 i believe, might want to ask him why on that, but he seemed happy enough at the time with them...
here's his build thread maybe he mentions something about them in there.

I'd say either are good, but if you are on the stock rims the do 255's w/ spacers. brian2sun mentioned he liked having the spacers because it gave him more stability with the tall skinnies. I personally like a wider tire better, but it does rub more. Really you can't go wrong with either as izz said.
Brian2sun went to 35's not 285's(33's). I have been running the 285's and really wanted to go to the 255 and so do a lot of other people. There is only 1" difference in width and have less rolling resistance. You will be fine with the 255's and personally would be my choice, however I do not do a lot of mud. If you do a lot of mud then it is a closer toss up with possibly a little lean to the 285. All other conditions the 255 is the winner in my book.
285= more square contact patch when aired down wider but not as long(mud)
255= long rectangle, better for conforming to rocks and other objects. cuts throug the snow and to the road.
The actual surface area is close in size but in different shapes. Of course this is just my opinion.
