Looking for larger AT tires to replace my originals without doing any mods?

I went with 275/70R18s because it was the best balance of price, size and looks. It fits without any modifications, isn’t too big to cause huge drop in MPG. Bigger sizes were a lot pricier (I got a great deal on my Falkens at $178/tire).

I have a 2.5/1 lift and could have gone bigger but the tires work for me.

 

I have lost about 2-3 mpg when upsized form 275/55/20 to 275/65/20 (31"± to 34"±). But, keep in mind that the circumference of the tire is now different, so you actually go further with each rotation, so calculated mpg is not correct. In my case the new tires are 7% bigger so my mpg is actually 7%± better than calculated. That helps to soften the perceived blow a little.
I also added the lift at the same time, so the added wind resistance adds to it, not just the tire size.

 

i corrected my calculations for the increase in tire diameter.

 

Got them on the wife's 4runner in E-load, they appear that they are going to last a long time granted there is a bit of weight difference between Tundra and 4runner.

 

Good info! Interesting how such a seemingly small change in tire size can make such a big change in fuel consumption. Makes me wonder if I should stick with the stock tire size, especially since some of the tires I'm considering are a bit heavier (more unsprung weight = more fuel consumption and less power as I just found out), more aggressive tread (more rolling resistance) and if I go to a bigger size, again a hit to fuel consumption and power.

Although I imagine the benefits would include marginally better clearance, better traction and it just looks more bad @ss, which is important, but I'm actually going for an understated, clean and under the radar look. I want my truck to look good, but not stand out in a crowd. Better traction and clearance off road is more important, as is a tire that will hold up to off-road and gravel road driving. And of course, since I tow my travel trailer, I need an LT or higher weight rated tire.

 

In got Cooper AT3 XLT... great tire with the mountain snowflake too. The price point was also great!

275 70 18

 

Those look good! I have those on my short list too - they come in less expensive than BFG KO2s or Falken Wildpeak ATW3, at least at the tire shops I called. I think it's the XLT. Looks fairly aggressive and the the tread wraps around the sidewall. Good to hear you're happy with them - nice to know a Tundra owner likes them. Some times tires can work really well on one vehicle but not another, but you've got them on a Tundra.

 

Thanks... they look much better in person too.

Ko2s was one of my other choices. These tires were 300 dollars less.

 

That's a pretty significant savings, and a bonus if they're better than the more expensive KO2s! I think a lot of people (myself included, in the past) just buy BFG KO2s because of their excellent name recognition and large share of the All-Terrain tire market. I know some people like them and some hate them, I guess you get that with every tire though. I might have to take another look at the Cooper Discoverer XLT though. They looked pretty good when I researched them last week. And those ratings (from tirerack.com I think) look really good, pretty high marks in every category.

 

I have been reading forum post after forum post for the past month. I can't for the life of me decide between 275/70 r18 nittos or ko2s.....I own a 2015 trd OR with stock 275/65 r18 tires with no leveling or lift kit. It seems with either selection I go with, I shouldn't see rubbing issues..but I still can't decide. May be a stupid question here but does a leveling kit alone lower mpg?

 

I think it all affect mpg. When the truck sits higher there is more wind resistance, so it will affect mpg, especially at higher speed.

 

Sounds like a good plan! I don't have any plans for a lift right now as I just replaced all of the suspension last year with OE style parts so I have the stock height, and can't justify ripping it out to do a lift. Maybe in a few years when it needs replacing anyways. But, I've heard from many people that the 275/70R18 is a great choice for the reasons you mention, like no modifications (maybe remove or heat and bend the front mudflaps to clear on full lock when backing up), and no huge drop in MPGs. Plus it should give about a half inch lift and is about a 33" tire which many consider the sweet spot.

I'm with you there! Still trying to decide, but will have to make up my mind soon. KO2s were my original choice since I had them before and they're quite popular. But so many people are raving about the Falken Wildpeak ATW3 I'm seriously tempted. Nitto has some good tires too, I kind of like thier Exo Grappler, still has the 3 peak mountain and snowflake rating. And a few other tires too. When there are so many good choices out there, it's overwhelming and hard to make a decision! I'm not going with a leveling kit because I tow a travel trailer sometimes and I think it might throw off the stance/balance with the tongue weight on it. If anything, it's an extra expense I don't want to deal with right now.

Makes sense. I hear a 2" lift is a good compromise (probably 2" all around), gives you a bit more clearance without effecting the wear and tear on parts, making the truck less stable or top heavy, and much cheaper that doing a taller lift yet still gives you a lot of clearance benefits. That being said, a lift or leveling kit is not in my budget right now, I'm buying 4 new tires for the Tundra and just got 4 new tires for my travel trailer, and I'm getting a new tonneau cover, so that's it for a while.

 

Where’s that tire page with all the tires on it?? Looking for all hybrid tire brands
