2021 Limited Tire Size Question

First time poster, have been spending a lot of time searching past threads to learn. I just traded my 2015 double cab with TRD off road package for a 2021 Limited. Stock shocks, 20" chrome wheels and tires. I did the deal knowing I'd want to change up the '21; if no other reason very much like the look of an 18" wheel over 20" and not a fan of the chrome wheels.

Took about 5 minutes to determine I liked the ride of my 15 with TRD off-road package better than the 21. My primary objectives are to tighten up the ride, improve the look, not lose significant MPG (can live with 2-3), and not have axx-sag when I'm towing my ~ 4,500 pound boat (truck sits about level with boat hooked up with the standard 2" rake). Have driven Tundra and Sequioa before that, with the standard "boring" Michelin Defender LTX's which have served me well; I'm looking to man-up a bit and try A/T. About 18k miles per year, close to 5k towing my boat, nothing "off-road". In Wisconsin, live in the "country" so snow traction important.

After gobbling up information and considering a number of options, I'm presently looking at this: Bisltein 5100's front and back, Toyota sway bar on the back, 18x9 20 offset Fuel wheels, Toyo Open Country AT3 tires. The guy doing the work is encouraging me to stick with the stock size 32" tire (275/65R18). I really like the look of a bigger tire, would like to go with the 33" (275/70R18).

Anyone run a 275/70R18 on a set-up I described above? If so, any rubbing or other modifications required?

Thanks in advance for any input.

 

If you keep the 20” limited wheel offset (whatever that is) you should be able to get a 34 with a little rub. I just installed 285/60 R20s (boring defenders) this weekend with room to spare.

 

275-70-18 and 285/70-18 fit stock trucks, stock wheels no issues. Wheels with less than +60 (stock offset) may need adjustment on plastics, remove front air flaps. Generally a Tundra can fit 33/34 w no lift, depending on how wide the tire is and depending on rim width and offset. Tons of pics of setups here so look around. Folks have fit 35s unlifted, but that may be more work than you want to do.

5100s will work fine, TRD rear sway is a great mod and you may want to look into RAS (active suspension) for the rear. Will stop sag when towing, hauling, lifts the rear about an inch and no negative impact on ride like you would get with heavier leafs or add a leaf, blocks. I think RAS is a better alternative than lift shackles. RAS helps support the leafs where lift shackles can cause leafs to flatten quicker.

Here is my truck w 275/70-18 (ran them stock before the lift) , Eibach Pro Truck suspension set at 2 inch lift in front, RAS in rear for an inch lift. I also run TRD sway bar. The truck drives and handles much better than it did stock.

 

Highly recommend the Roadmaster Active Suspension to help your rear leafs out.

 

First question I always ask when upgrading is “What is my budget/what am I willing to spend?” I just recently hurdled over this issue. I have an SR5 and stock SR5 wheels are the ugliest stock wheels out there. So wheels were a must! Personally love bigger tires and smaller wheel look. I don’t intend to off-road much, I daily drive mine, and occasionally tow.

With my budget, I went with 35x12.5x18 with Falken AT3’s. Skeptical of all terrains because of highway road noise but Falkens had good reviews. Don’t believe I needed a BMC, but had it done anyways in case. Minor adjustments to front wheel under cover plastic.

Went with Bilstein 6112 in front and 5160 in rear. CB shims in front and CB +3 shackles in rear. I run the 6112 at middle setting so gives the truck a slight rake. It levels out when I tow anything heavy.

Hope this helps. My set up is about $5-$6k. might be more than what you want but just an idea if you did want a basic lift and large tires for a decent budget.

 

Great looking setup. Wish ida bought Cement when i bought my truck

 

You say you want the truck to be level when towing like it is now - but I don’t see anything you’re doing to lift the back.

I tow a boat that’s a little heavier and went with coachbuilder +2 extended shackles to get some rear left.

 

Thanks to everyone for your input. I ended up going with Bilstein 5100 on front (middle setting) and back, TRD rear sway bar, Fuel Blitz gloss black 18x9 +20 wheels, Toyo Open Country AT3 275/70R/18 tires. Just completed but so far extremely pleased with the ride and handling characteristics. With limited miles, MPG about 1.5 less than stock per the truck read-out. I do have minor rubbing in reverse at full lock. Hooked my boat up, very limited ass-sag. Have the Road Active Suspension kit on my radar, will assess after I start towing again next spring.

Next up is installing the Diamondback SE! Thanks again for the input.

 

Can you post of few pics showing the poke with those tires and the +20 offset wheels? I am considering new wheels, run same size tire.

 

Depends on the tire. I did 275/70R18 on +25 offsets and had rub.

 

5100s, middle clip, 18*9 25mm offset, 275*70*18, no rub
