Topic: tires

[Howard Shannon]

Currently I have stock size tires on my 05, 275/70/16.  They are michelin atx m/s.  I like them a lot, handle well on road and handles dirt roads well.  I'm looking to upgrade with a little more aggressive tire.  My trail goals are back roads, touring, logging roads, snow, some mud.  Not a lot of rock crawling if any.  

Couple tires I like,  michelin atx a/t 2 and cooper discoverer at3.  I even like the tmaxx and dare I say the duramax.

Reviews are positive on all of them.  

My question, does any one recommend any of these and is so, is gas mileage affected much and would it be wise to get the tire a little bigger then stock like a 31 inch? And would the 31's affect gas mileage?

Gas mileage will be affected any time you go bigger and heavier. How much depends on your driving habits, weight difference and size difference.

For your type of driving, I would go with the tried and true BFG All-Terrain K/O. I don't how they compare to the ones you listed in terms of price but I can't imagine there is much difference. I'm bias though, it's the only tire that I have run on my previous and current truck.

Tried Cooper off a couple recommendations and good reviews and have been impressed with the tires - not mudders by any means but capable in mud, snow, foliage and pavement.

I only went 31" with my 09, and they are very capable but 32" or 33"  would have been the better call. Makes the X look more propper in its stance. It may take a mile off your mpg but depending on your commute it may not be an issue. I'll definitely want to upgrade soon.

Thanks guys for the info

Btw, if 275/70-16 is not a typo, you're already at a 31" tire. You can bump up to a tire that is roughly a half inch taller with 265/75-16 or choose from one of the tire sizes that is roughly a 33" tire. Remember that it all depends on the manufacturer too.

285/75-16
255/85-16
305/70-16

These are metric sizes and need conversion to standard. The first number represents tire width in millimeters, the second number represents the aspect ratio (or the sidewall height compared to the width), and the last is wheel diameter.

For example, there are 25.4mm per inch; therefore 285 is 11.22" (285mm/25.4mm).
Then, 75% of 285 is 213.75mm or 213.75/25.4=8.415". This is sidewall height.
Lastly, to get overall diameter, multiply the sidewall height by 2 and add the wheel diameter. (8.415x2)+16=32.83".

HS...updated your poll with tire diameters to help gather info for you...let me know if that was what you were looking for?

And like that I get it!  THANKS!!!

I run the Hankook ATs on my Cummins. Did a lot of snow driving when I was in the east coast, they handle it very well and clean up nice. Mine was a Load E tire, so you might want to look at the reviews for D rated and see what people say.

Thanks, its good to know my tire size is a 31, now just comes down to, does more aggressive tread pattern like an a/t, effect gas mileage, like the cooper at3 or the michilen ltx a/t.  If gas mileage not changed much, I would consider cooper tmaxx.

31s are a good entry-level upgrade to stock tires.  Once you have a bit more of a lift, you will move up to 33s. That's what I'm going to do by the end of the year.
You might as well start getting used to the fact that the more you get into offroad and the upgrades,the more your mileage will suffer.  More so with engine/Hp/Tq upgrades.
