275/70/R18 Tire Question

[MH]

I am looking at putting a new pair of shoes on my Tundra w/ out lift. Haven't decided yet between BFG AT/KO or Nitto Terra Grappler.

If I go w/ AT/KOs will throw on 285/65/18s.

Nitto makes a 275/70/18 in addition to the 285/65. Searched through posts and did not see anyone w/ that size. Would it fit stock?

Any opinions on which size would look better?

I installed the Cooper ATS 275/70/18 and a leveling kit from customtoyz which is a 2.25" kit. The tires only rub slightly on the skip plate in a hard turn. I trimmed the skid plate and good as new. The cooper is a 33.2" tire I looked at the BF & the Nitto I liked the tread pattern better for my use and it comes with a warranty for an ATR 50,000 mile. It's a 10 ply but I'm running about 50-55 lbs and they ride great and they got real good reviews.

Just for info, I put BFG AT/KOs, 305/65/18 on my stock wheels last week, no problems except the already mentioned trim on the skid plate. Look and ride great. Here's some pics.

I bought the Nittos. Luvem. Quiet, good ride. Did not affect turning radius. See pics. Click camera.

TundraNC...did you install a leveling kit as well? If so, which kit did you go with. I'd like to purchase the BFG AT's in the 305/65/18 size and need to figure out whether or not I need the leveling kit. Great looking truck!

Thanks, Tex, I have the Tough Country kit, you can just see the spacer at the top of the front springs in the 2nd pic, but you won't need any lift for the 305 tires, just the minor trim on the skid plate.

Those running boards are the best I've seen for a stylish look. I also like the bed bars but none of that would make sense on my performance 2WD Tundra.

The step rails are N-Fab, and the bed rails are actually a Dodge part, obviously I painted them both to match. Thanks!

just do yourself a favor and get a leveling kit man..why put on bigger tires without one. Will look better but with the kit it will be 200000 times better

BRENT87,

Thks for posting pic. Those tires look great. Was leaning pretty heavily towards the BFGs but think the 275/70/18s look really good.

Brent do you have any type of lift on your truck?

[Brent87LT1]

No lift. No rubbing. 275/70-18. The last truck I lifted 2" in front for tires cost me 1.5 mpg. I drive about 90 miles/day to & from work so every little bit counts. Also, since I removed the stock running boards, my wife & kids have enough trouble getting in at this height. I do plan to install AMP-research steps. When this is done, I may raise the front a little.

[TundraTX5707]

Thanks for the info.

Do you figure the lift is what caused the decrease in the mpg and not the tires (or part of the decrease)?

Did you notice any decrease in mpg going to the nittos?

[Brent87LT1]

First Q: The tires probably did hurt the mileage some. (I did correct the speedo) But from what I know about aerodynamics, the less air under the better. As with almost all cars/trucks, the bottom is not smooth like the top. So the higher you raise it, the more air underneath, the worse the mileage.

Second Q: I have noticed a little acceleration drop. Can't accurately figure the mileage b/c speedo has not been corrected. Waiting on a power programmer to come out that does more than just correct speedo.

The stock tires are so light weight. I probably added 80 lbs of rotating mass.

I am 5 inches taller than stock and still get 17 city from 5.7 4x4, so take everything with a grain of salt.
