I am super tempted to go for the 285 Duratracs but I'm not sure it makes sense to put nearly another grand into a vehicle that is worth next to nothing.
Not to resurrect a super old thread, but this is *exactly* where I'm at. My needs are also really similar to OP (including living in CO and needing to consider uphill power on highways, traction in the snow, and moderate and very occasional off-road use).
I have a 3ish" ToyTec lift that's a few years old now, and I have a set of 265 Yoko AT/S's that I got before I knew I was lifting. They were great for the first few years, but their winter performance has sucked these past two winters.
So, I know I'm buying Duratracs, I just don't know if I'm getting 285s or sticking with 265s. I was all set to decide to stay with 265s because of all of the horror stories I've heard about reduced power with stock gearing, and knowing that I already need all the power I can get to maintain highway speeds up the high highway passes here.
However, I was recently told that because I have a factory e-locker, I have 4.30 gears. That's news to me, and I was told that I won't notice a huge difference if I switch to 285s because of the gearing.
The reasons I'm leaning toward 265 are:
-My 97 has 215k, and as valuable as I think it is, I know it's not worth much anymore and I sincerely doubt I'll be able to sell it for anything that would be worth it for me knowing how much blood, sweat, tears, and money I've put into it. It seems like dropping $1k in 285's is a silly investment for a car that old, no? I know with the way I'm doing preventative maintenance on her I can maybe eek 300k out of her, but I also know that it definitely won't be the $6-10,000 car I feel like I have now.
-While I have no frame of reference to know if I would benefit from 285s, my 265's have gotten me everywhere I've ever wanted to be. I don't crawl with my runner, but I certainly take her off-road to awesome camp sites and trail heads. On the other hand, hardest trail I've been comfortable driving was a 3 on TrailDamage (Italian Creek), and I honestly have no interest in doing anything where I feel like I'm going to break something important on my daily driver again.
So, if I haven't needed 285s yet, why should I get them now? Admittedly a big reason is the looks of 285s on a 3" lifted runner versus 265s. Another reason I was thinking is for better traction in mud and snow on trails, but I have no evidence that says 285s would be better than what I have. I also have no idea if it would have made a difference the one time I did get really stuck in mud and needed an "extraction".
Convince me otherwise?
