Fuel and gasoline will continue to rise in Ca.
$0.12/gal starting in 2015 in lieu of the already bs cap and trade scheme here.
Then add on the 70% reduction in sulfer. Administration spokesperson claims $0.75+/gal. oil industry says 6-7 cents.
The economy's gonna love this.
bring on a 275-80-17 E-rated w/4000# capacity.

They are doing ok. I've got 17K miles on the them and I'd say the fronts are at 40%. I say ok because they are doing as well as any other tires I've had. Rears are probably 70% but I have always gone through 2 sets of fronts for a set of rears. Last set if tires were 235 Toyo M-55's and got 40K out of the rears and those lasted the longest. Probably could have gone longer but the second set of fronts were done. The KM2's should get to 30 or 35k I'd guess. These don't have the "snowflake" either which may mean the compound is harder. A buddy has snowflake KM2's on his f450 and at 23K-ish he's getting ready to replace them.

My rig isn't a daily driver so I'm ok with how they are wearing.

i was running 275/70/18s which is like a 33x10.5 tire. went from a 325/60/18 which was a 33x13.5. definitely didn't feel as stable when towing and the steering felt kind of twitchy with the narrow tires. mileage maybe went up a bit but not enough to really notice.

didn't do much off roading but in the snow and mild field playing, they worked well.

Thanks for the info. I have M55s in 255/85-16 on my dually now, and am not super impressed with the rate of wear. They are a great tire, but cost vs wear... I found I can get KM2s from our wholesaler for $110 per tire less than Toyo MTs in the same size, and M55s are usually +/- $30 more per tire than the Toyo MT. $140 per x 6 tires = a whole lot of diesel!!!

spend too much time in sand, mud and snow to want skinny tires. They're great for hard pack and cutting thru shallow mush, but terrible when you need some flotation or greater traction in more unforgiving conditions.

and for this winter I had some used 235/85/16 bfg at on 16x8 american racing genaric wheels, I got 2 new general at2s 235/85/16 and put them on some old ford alcoas I had. The x8 wheels are too wide and dont keep the tire tall enough, so Ill get 2 more generals and mount the set of 4 onto some 16x7 cragar soft 8s I have, and keep the bfgs for spares.

I think I might sell the 285/75/17s or put them back on my diesel, and buy some 235/85/16 bfg muds, toyo mt, or goodyear mtr for the blue truck. I wouldnt mind getting rid of the Rockstars, but they were a gift so thats probably not a great idea. I know most people dont like the look, I do, its the weight factor that bothers me.

pizza cutter 235/85/16s on 16x7 soft 8s. Gave these tires to my dad, good highway tires but not much traction in sticky stuff.
