275’s on stock ‘21 pro wheels?

Double Post

 

My TRD ORP had BFG KO2 275/70R17 Load E with no lift and stock TRD ORP wheels and did not rub. The only complaint was the Load E tires were not comfortable. If was too firm to me even running at 32psi and especially for Mrs, she hated it. Originally tire shop put 40psi and it was pretty bad. I had BFG KO2 265/70R17 Load C before and right when I pull out of the tire shop the first thing got to my mind "oh sh*t, what have I done.". Probably why 275/70R17 and 255/80R17 are not a common choice for 4Runner world.

Later I got a lift and BFG KO2 285/70R17 Load C on stock TRD ORP wheels with minor trimming on bottom of front fender was the best upgrade for me.

 

Sooo…. What’s the conventional wisdom here about putting a set of the lighter 285 70 17 Falkens on the stock ‘21 TRD Pro wheels?

 

285/75/17 on the previous gen pro wheels, aired down to 15 psi every weekend, no issues.

 

With TRD Pro wheels its little tricky as they don't meet the minimum width for Falkens 285/70R17. Only TRD Offroad wheels meet the minimum requirements for them

With a lift and some good wheels 285/70R17 Load C tires are a nice balance for offroad fun and on road comfort.

I have Falken P285/70R17SL rated tires for more on road comfort and to run on trails carefully kinda deal.

So my vote is stock height & good 265/70R17 or lift + 285/70R17 SL or Load C.

 

Thanks for the information. Do you have the 285’s on your stock TRD Pro wheels (wheels not “rated” for 285’s). If so, With or without a lift?

I do light off-roading in NM so wouldn’t be terribly concerned about lighter 285’s on the stock rims. However, I went with heavier Falken 275 70 16’s on after-market rims on my last T4RSR5 and, as you point out, the weight was noticeable and the dreaded wobble raised it’s head. Don’t want a repeat performance on the ‘21 Pro.

 

My TRD Pro still running stock size 265s and stock suspension.

My Limited and TRD ORP both got TRD Offroad wheels with 285/70R17. Limited got the lowest lift where front is 2.25in (reduced 1/4in from original 2.5) and rear is 1.5in lift. Only very minor trimming was needed to fit 285s.

 

Gotcha. Thought it might of been on your LTD with off-road wheels. BtW, it looks great.

 

Sooo… I was ready to pull the trigger on the Eibach pro lift kit you guys referenced but as the final step in my due diligence, I called Eibach to verify fit for the application etc., and they told me this kit won’t work for the 2021. They say there was a change made by Toyota in the front suspension after 2020 model and this kit won’t work and they haven’t yet developed a kit for ‘21 and newer. Guy I spoke with at Eibach said “might be a couple of months” before a replacement is developed. Seems the rear springs on the kit are still good to go - not the front.

Curious to know, T4Running: Do you have the referenced Eibach Pro Lift Kit on your ‘21 TRD Pro?

 

Are you still running the Eibach springs? How do you like them? Looks like you take it off road a fair amount. Anything noticeably different in how it drives compared to before?

 

I have Fox 2.5 now but used the eibach setup for quite a few trips and they always performed well.

the only thing they changed was adding some stiffness and getting ready of body roll

 

I’m running 285 70 R17 BFG KO2S on my stock rims with a Westcott Precollar lift. Lots and lots of folks run the 285s on the stock TRD Pro rims and air down with ZERO issues. You’ll be fine with the 275s or 285s with lift.

 

I wonder what is the real reason for this wheel width requirement.

Is it like the center of the tire would wear out more since the walls are pulled inwards?

Is it because the beads have too much stress it been pulled inwards?

Love to know the reason why tire manufacturers have a minimum width requirement. Anyone know why?

 

I just put a set of 275/70/17 Falkens on my 2023 Pro the other day. They fit great and I have not experienced any rubbing. I wanted 285s but Im not ready to lift it yet so I went with the 275s for now.
