I just can't make my mind up about these tires. Half the people say they are great, the other half are not to thrilled. It makes it hard to pull the trigger on them.

In the winter these tires are not very good, better than the stock tires though. I am running 40psi on my 305/55r20's and have about 8,000km on them so far with very minimul thread wear. I run that low of pressure because I have stock rims which when pressure is increased too much the center likes to balloon out. That would cause alot of excessive wear. Very happy so far in that aspect.

I got a set of 275/65R20's with a little over 12k on them and they are outstanding. Never have any trouble with traction and handled old hunting roads with ease. Couldn't be happier with performance.

I've had them on my truck (2010 F150 SCREW) now for 3 months. We're experiencing one of the most brutal winters we've had in decades in NW MI. Over 130" of snow so far and ver cold. Satisfied with the traction of the Toyos on ice and snow compared to my Michelin AT summer tires. I also plow with no issues.
IMO there isn't a tire made that's good on glare ice, except for studded tires, which are illegal in MI. Best to slow down when icy. 4wd can get you in trouble in a hurry when there's ice.

I have a 2011 fx4 SCREW with a two inch AS level in the front and 295/60/20 toyo at2's on the stock 20's

I contacted toyo and gave them information about my setup and they suggested a psi of 45 for both the front and back. I inflated to the suggested 45 psi, and then did the old school 'chalk test' to figure out how they would wear over a long period of time. Come to find out, 45 was too high and the center of the tire was receiving much more wear than the outside, so I lowered the psi to 39 and they seem to be doing much better.

hofstet-i'm originally from TC area, my parents still live up there, I've been hearing all about the massive amounts of snow from my mom. good luck driving around in that stuff, I don't miss it at all.

There could be a few differences in our pressures.

1. My tires are a little narrower. Less likely to get the ballon effect.

2. I run 18s, you run 20s

3. My truck may be heavier than yours due to what each of us carries. My truck is about 6400lbs as it sits right now but I carry a lot of stuff. Tools, straps, axe, shovels, chains, come-a-long, rope, jumper cables, and a bunch of other stuff. Add in wife, kids, and all the crap they pack. It adds up fast.

4. I found this pressure to be a good compromise in a smooth unloaded ride and being able to hook up to a trailer or heavy load without needing an air source.

So far my tires really show no signs of wear with over 6k miles. Sounds like your doing it right though. Each truck and person will prefer a little different pressure for their liking.

So basically to figure out what psi to run the tires at, i just need to do that chalk trick and see where its wearing?

Guys, I bought 285/55/20 Extremes 2 weeks ago and drove about 2000 miles on a road trip. My 13 Ecoboost Crew 157" 4wd did not like them at all. Averaged about 15.4 mpg the entire trip.

I decided to take them off and give them to my brother who had just purchased a 13 5.0 Screw. Drove his stock 18's back up north and averaged around 18.6.

Today I went and bought a new set of 275/60/20 AT2's and mounted them on new platinum rims. The fit is great, no rubbing without a level. MPG are actually trending up after about 100 miles of running around today. Truck feels better and the tires don't seem to hold it back like before.

FYI for those of you that are thinking about the Extremes due to their looks, they will reduce your mpg and performance.

Don't blast me if you love your Extreme's (as I loved the look), I'm just trying to inform those who are trying to make a decision.

I've heard more positive things about the AT2s than the Extremes.
