Anyone regret going to 275/70/18’s on their stock Tundra?

Considering going to 275/70/18’s on my totally stock 2010 Tundra 4x4 TRD. It’s a utility + hunting truck, occasional 1-2hr family road trip, nothing big.

I figured I’d go a size up for a touch of extra ground clearance on the snow-covered winter hunting trails.

They are quite a bit heavier, and a little taller, so I’m guessing the gas mileage and power will take a hit...

... what do you guys think? Any regrets?

 

NOPE! I went from this.....
To this and I love it so far.....

 

Did you noticeably take a hit on gas mileage and power?

 

I’ve gone about 2 1/2 years and about 50K miles on mine and no regrets. Mileage went from 16 to about 14.2. They rubbed the front forward little mud flap bad in reverse and at full lock, but I think that’s because my wheels are aftermarket with +25 offset. Like I said, no regrets at all and am thinking of going with a slightly bigger size now that I recently installed Bilstein 6112s. Otherwise, I’d definitely stick with that size if I were to renain at stock height up front.

 

I may go back down. Killed acceleration and braking. Gas milage went from 14 to 13.1. Part of the difference is weight. I think the stock Michelins were 5 ply and the bigger Ridge grapplers are 10.

But bigger does look better.

 

I have 20" wheels but went up a size to a true 33" (Michelin defender) from stock bridgestones. I didn't lose any mpg or power as far as i can tell.

I very highly recommend the Michelin defender lxt ms tires. Sounds like they will suit your needs very well.

 

I’m very pleased with the cooper discoverer I put on. Not any significant change in mileage, 14.5mpg +/-.
This size suits the truck much better and actually required no speedometer recalibration.

 

How about the change in braking or power?

Looks really great....!!

 

Not noticeable, really. I carry a considerable load, so I don’t have the neck snapping acceleration anymore that it’s famous for, but when I choose to get on it, she jumps out there and moves. Likewise, braking is great too. I’m pretty sure that going much larger than this you’re liable to have regrets.

 

Another size is 285/65 for stock. It's what I have. 1/2 inch taller and 1/2 wider. No noticable difference. Had to remove front mud flap with +20 wheels.

 

Older Tundras must have come with smaller tires. My ‘18 has 275/65R18 tires stock, so 275/70 would be the same width and only 1/2” larger in diameter. Would lift the truck a quarter inch. I don’t think I’d have any issues with that size. MPG loss would come more from our tendency to put heavier AT or MT tires on our trucks when we replace them.

 

Not sure at the moment. I was stock for a year, then put a Icon stage 2 lift on recently with 275/70/18 Cooper St Maxx tires paired with method Roost wheels at +18 offset.

Didn't really notice a drop in gas mileage, but I did notice braking, steering, and accelerating took a hit as well as on-road comfort. Part of me thinks I should just throw the stock wheels and tires on with the lift though.

Will probably keep my 17 tundra for another year, then upgrade to the 2020 tundra when it comes out.

Sort of miss the stock driving dynamics and look occasionally.

 

you can get p rated 20's in a 33" tire with some brands. I've considered this option to fill the wheel wells but haven't committed yet.

 

What rails are those?

 

Go Rhino GB20. They seem pretty sturdy and stick out a little which should help prevent door dings.

 

I definitely noticed a difference in braking and acceleration as well. To combat the acceleration, I turn on Tow Haul mode and turn off Nannies.

 

Thanks for all the replies. I’m going to try the 275/70’s.

 

Do you have any pictures of this, I have same stock setup and wanna see what they look like. Thanks.

 

Not a great pic. Looks close to stock but a little better IMO. Fills in those huge wheel wells better

 

What size are they? 275/60r20? That's what I am thinking in BFG Ko2's.

 

Absolutely no regrets here! My truck came stock with the 255/70/18 bologna peels and looked horrible. Same height as 275/65/18, but skinnier. I originally moved up to a 265/70/18 and then to a 275/70/18. The stock tires are 32.1" tall and the 275/70/18 are 33.2" tall. Definitely a nice improvement!

 

Weight is the enemy when upgrading to any real 275/70 all-terrains, as virtually all of them are E-rated.

I had 275/70 BFG K02s on my ‘17 SR5 with a 3/1 lift, and I could definitely notice the difference in acceleration and comfort on the street. That truck got 13.5 all day long, but I didn’t buy it to hyper-mile and sip petrol.

They were fantastic in virtually all other respects, and they look great.

 

Mpg did take a hit after ko2 275/70r18, but they look good!

 

I regret going with 275/70/18 KO2.
I should have gone bigger.

 

Do the 275/70’s rub on stock-height Tundra’s (my 2010 has the off-road pkg with Bilstein’s) ?

 

I made the same mistake. Bought the 275/70s while stock, but then upgraded to a new suspension system soon after. The 275/70s looked too small. But, they had plenty of life left in them, so I let them run. They are finally getting replaced tomorrow with 295/70/18.

 

I prefer the 32.1" tall 255s, they only look small if you've lifted your truck.
225s are lighter so they spin up & slow down faster than larger tires.

 

Every truck is slightly different, but probably 99% of people don't have any issues rubbing on a stock truck with that size. I ran it stock on mine for about a month.

 

I think the ST Maxx looks really good in 275/70/18, and appears much larger than it is. Also saves a ton of weight over 295.

 

Mine did along the front little flap in the front fenderwell area, but only in reverse and while turning. I think that’s because my aftermarket wheels (MB 352s) have less backspacing than the stock wheels (+25 vs +60). I haven’t heard of anyone with stock wheels rubbing that little front flap with that size tire.
