It would be good to see your 4Runner in Ouray at the next FJ Summit, you are not that far away.

Yeah, my brother has a FJ and wants to go with me too. Just might do it! Thanks!
I have the same size but in BF MT KM2... (spare tire included) and NO PROBLEM... They fit perfectly!... But now, I'm using my truck 99.99% street, now I want those...

Did you keep your toytec coilovers set at the factory shipped setting or did you adjust? I'm about to install the Boss kit myself and I really like your truck's stance. I also purchased the S/T Maxx 255/80-17's.

Factory shipped settings. Thanks! You'll love it!

I didn't go through your whole build... But can I ask?
Did you do any trimming, mud flap removal, or BMC in the front for rubbing?

I have not. With the stock wheels there was no rubbing, but with my Konig's the driver side rubs the mudflap slightly when turning at low speed. I haven't tried to remove them yet since it's pretty minor.

Less weight per tire, less wind resistance, less rolling resistance, less wear and tear on suspension and steering components, they're better across the board.

Tires look great....I ran some 33x10.50's on a lifted 2dr Jeep XJ, being swampers they were killer in the snow and awesome in mud. Never even aired them down, in 26in of snow I seriously had no real issues. I like the tall and skinniness of the 255/80/17 and may run those when its time to replace the 285/70/17's my truck came with.

Mpg have been decent. Averaging around 16.2-16.4 daily driving. Mix of city and highway. I drove to the lake last night and only managed 15.7 but there was a good wind and cruise was at 79-80 most the way. If I slow it down to 70-75 its much better.

I've been keeping it around 40-42psi cold. I tried 45psi and it was starting to feel like it wandered a bit on the highway. At 35psi (spec) mpg's were taking a big hit.
Remember that when you calc mpgs you have to factor in the taller tire over factory to get an accurate comparison.
Since the new tire is taller you will end up traveling further with every revolution of the tire. Get the diameter for each tire and divide out to see how much further the larger tire will travel as a percentage - likely 3-4% further-ish.
Don't have the calcs for each tire, but it will likely result in around 1-1.5 mpg difference when calculating using gas used and distance traveled.

I currently run 265x70x17 duratracs and have been looking for 255x80s to get a full 33" tire. However, I live in Boston and drive through some serious snow and shitstorms for half the year.
Anyone have any real world experience with these coopers in snow? Are they good? Can you compare these to the duratracs perhaps (which are GREAT).

We've had an extremely mild winter here in OK, although I'm staring out my window now looking at snow and ice all over the roads. It's been nothing more than a light dusting though. I'll say in what we have had the Coopers have been fine. As far as the real deep stuff though I don't have any experience in that.

hello :yo:
Really like the stance of your rig; I'm going with OME (light, don't carry that much weight around with me on a daily basis) w/the S/T Maxx in 255/80 on stock wheels. Question, do you have KDSS? Just inquiring if you have any lean to the passenger side if you do, doesn't look like it in the pics. Also, what psi have you settled on?
Thanks!

No KDSS. No passenger lean. Mine leans slightly to the driver site. I keep them around 38-40 PSI.
