Largest tire size on bone stock 2016 Tundra TRD Pro

Hi All-

Not to beat a dead horse...and believe you me, I have searched multiple discussions on this topic, but the question is still not 100% answered in my head. I am wanting to swap the stock tire size for the largest/widest tire without any sort of mod, with the exception of possibly removing the front "spat" flaps?

I believe I have narrowed it down to the following sizes:

305/65/18: Remove spat flaps only?

295/70/18: Straight swap no mods?

285/75/18: Straight swap no mods?

285/70/18: Straight swap no mods?

I would prefer the 295's if the only mod was to remove the spats.

Thanks in advance!

 

Side note: I might pick up some "like new" 295/70/18 Nitto Ridge Grapplers for under $1k. 98% tread or so they say.

Could save me ~$1k if these would work.

 

within the link @Sierradevil listed. read this and that'll explain it. trd pro comes with 2" of lift on them i believe.
Second Gen (2007-2013) and Third Gen (2014+) Tundra
No Lift Kit
Max tire sizes are:

• 18″ rims: 285/65 R18 – 5/10ths taller and 4/10ths wider than factory. Trimming may be necessary.
• 20″ rims: 275/60 R20 – one inch taller but same width as factory

1.5 – 2″ Leveling Kit (or less)
When installing a leveling kit, you might be able to fit some wider tires than what we have listed. It may require some trimming though, but it is possible.
Max tire sizes are:

• 18″ rims: 275/70 R18 – One inch taller but same width as factory.
• 18″ rims: 285/70 R18 – 4/10ths wider and 1.7 inches taller than factory. Trimming may be necessary.
• 18″ rims: 295/65 R18 – 1 inch taller, 8/10ths wider than factory. Trimming is probably needed due to width.
• 20″ rims: 285/60 R20 – 4/10ths wider and 1.5 inches taller than factory.

3″ Lift Kit
With a 3″ lift kit, the options continue to get better. However, the wider the tire, the greater the likelihood of trimming.
Max tire sizes are:

• 18″ rims: 285/75 R18 – 4/10ths wider and 2.8″ taller than factory.
• 18″ rims: 305/70 R18 – 1.2 inches wider and 2.8″ taller than factory. There are Tundra owners running this size, but trimming is required. Replacing the stock wheels with after-market 18′s that have less backspacing is recommended.
• 20″ rims: 285/65 R20 – 4/10ths wider, 1.6″ taller than factory.
• 20″ rims: 305/60 R20 – 1.2 inches wider and 2.4″ taller than factory. There are Tundra owners running this size, but trimming is required (it’s a tight fit).

 

Sounds like 285/70/18 would be the way to go with no mods

 

get after it!
if it doesn't work.....

 

Just to further complicate things, I have 285/75R18 on factory Pro suspension. I removed the little mud flap in front of the front wheel. That’s it. Minor rub at full lock when off camber on a trail.

 

This is a pretty ideal setup, skinny 35s, stock wheels keep the wheel close to the pivot point and results in minimal interference. 285 likely has minor extra rolling resistance but gain the benefit of a much better clearance. Lowers the final gear ratio which may increase cruising mpg, or at least offset.

 

Thanks for the feedback. I was initially going back and forth between 295's & 305's but was concerned with UCA clearance.

Maybe I will try my luck with 285/75/18's

 

I'm reasonably certain 285/75/18 will work just fine.

I have a set of wheels with duratracs in this size on rims, but haven't taken the time to put them on my truck yet.

Others have said 285/75/18 works with TRD Pro, and I'm taking their word for it!

Thanks all- will get 285/75's installed and post some pics when done.

My 21 Pro removed oem wheels. Added SCS wheels and had to remove the little flap in the front. Running 285/70/18’s.
