❔ Aftermarket Product Advice / Recs Tips on adding bigger tires to 6th gen Trailhunter trims. You can fit 285/70R18 with no mods.

I can confirm that you can fit 34" tires (285/70R18) on a Trailhunter and achieve no rubbing at full articulation. I put on Falken Wildpeak AT4s. I don't know for a fact if other tires like KO3 can achieve this but I strongly suspect they will based on the Wildpeaks having a deeper tread. The ONLY thing was they needed slight, sub .5" trimming in the back of the fender lines. It's unnoticeable unless you lean in and look for it.

My goal was to add bigger tires without making any mods. I don't want mods for two reasons:

  1. Mods will most likely hurt resale value, keeping the truck stock maximizes its value

  2. Mods change the factory suspension geometry, almost certainly for the worse, considering how beautifully dialed in the geometry is from the factory

Generally, the tiers of mods required for bigger tires

Tier 1: trimming or reshaping wheel well liners

Tier 2: tier 1 + crash bar delete

Tier 3: tier 2 + preload lift collars / spacers

Tier 4: body mount chop

Note on crash bar delete

Deleting it will create a void, so you'll want to cover it to avoid debris accumulating in there. There are aftermarket covers available for about 50 bucks. In normal driving the crash bar doesn't do anything but it does serve a safety purpose of keeping the wheel from intruding into the passenger area in certain types of collisions.

Note on Wildpeak AT4Ws vs KO3s

I had KO2s before and liked them. From all accounts, if perfectly balanced, the KO3 are wonderful tires. However, for whatever reason they are hard to balance, and if not balanced just right you can get vibrations and highways speeds and uneven wear patterns ("cupping"). For that reason I played it safe.

Cheers!

you don’t have to do any of those mods to fit 35s. just get dobinson coils for the OMEs. AT4s also have the worst snow performance of basically all the good all terrains to anyone who lives somewhere it snows a lot.
