I have a question on tire sizes.

I got a 2020 4-Runner Trd pro. Currently running 285/70/17 I'm thinking of possibly running 35s in BFGoodrich Mud-Terrain KM3. Or maybe a KM3 in a 295/75/17 or 295/70/17.
Any recommendations? Also, I have a westcott lift which I believe is 1 and half inch lift. Right now I have some room that's that I'm running a 285/70/17 I will post pics

 

Start cutting... body mount chop or body mount relocation kit.

Plan on some serious offroading?

 

The people at my Offroad store told me there's no need for 35s. Which I disagree what are your thoughts?

 

I'm currently running a 285/70/17 RIDGE GRAPPLER

 

You rig, knock yourself out.

 

Enjoy the 285s...

 

Here’s a good informational video with moving up to 35s on a 5th gen 4Runner.

I guess the question is why do you think you need 35s? Offroad store said they aren't needed - is that based on your use case? Location?

From what I've read, anything over 33" you are probably going to want to regear, on top of BMC and other cutting to get them to fit. Major mods.

If you want or need them, can afford the mods, and don't mind hacking up the truck then go for it! I have 285s and, in all honesty, probably don't need them. I like the looks and peace of mind even though it doesn't really give you much more clearance. It's as far as I'm willing to go though unless I had a dedicated offroad behemoth and if I were that hardcore, I'd probably just buy a jeep and resign myself to lots of maintenance and trail repairs
