AT4 Oversized Tires

[Trailboss91]

Anyone successfully put 285/75r18 tires on a stock AT4? I am looking at this size in the Falken Wildpeak AT3/W, they measure out to 34.8” tall and 11.2” wide.

I'm on that size tire but have the 2" SST. Very minor rubbing when turned going over a bump. Normal conditions, nothing.

What wheel offset?

Stock 18's.

Have any pictures?

No good ones but here you go.

 

285/75/18 Nitto Ridge Grapplers

Stock 18s

No wheel spacers

Zero Trimming.

Zero way to go any wider of a tire without hitting the Ready lift UCAs unless wheel spacers are added, which will probably cause more rubbing issues.

Only rubbing as mentioned above (Slight rub going over a bump at full lock)

 

Truck has a 1 to 1.25" rake with the 2" SST.

Here is my 2019 with same Ready Lift SST kit.  Also some photos of clearance of stock 275/75/18's on  on Method NV's which are a 12mm offset versus 26mm for stock.  So 285's would be very tight with RL UCA - but there is more room with stock UCA's

For reference, here is my tire clearance with the RL UCA (Tire specs in above post). 

Note that the outter lugs on the tire are not offset in the image so clearance is less than shown.

I've articulated the suspension pretty well to check for rubbing and haven't caught any marks yet but it is certainly close. 

 

I'm convinced on this size tire, it will 100% come down to actual tire selection and not all 285/75/18's will fit without wheel spacers.

For those interested I went with the 285/65/r20 NRGs

I'm not adding a level for now, so these were the biggest I could go without trimming

They'll fit fine as long as you only drive in a straight line.  You WILL HAVE rub with the inboard front fender liner and "probably" in the rear of the fronts at the mud flap and/or liner.  I just installed 285/75/18 on OEM wheels on my AT4 with the Rough Country 1318 - 2" leveling kit and they just clear at full lock and no articulation.  I imagine if the suspension is heavily loaded while off-roading and near full lock I will rub the fender liner on the inboard side in the front.  It's really close without any articulation.  Tires I installed are the Toyo Open Country AT3 in 285/75/18 which are 34.8" x 11.3".  If I do rub it will be minimal and I can get a little more room if I zip tie the liner back as many have done.  Anything wider than 11.3" would cause me problems.

Has anyone run 295/60-20 tires on a 20x9 wheel with near zero offset and a leveling kit?  Ive seen other AT4s running this tire on a stock wheel with 26 offset, but not sure if the ~1" shift in wheel position would cause rubbing.  I'm also concerned with the difference between no rubbing on the pavement and no rubbing while light off-roading.  I could go with the 285/60-20 and be fairly comfortable, but I wanted the 295.  If i go 295/55-20, im not gaining much in diameter and it sort of seems like im not using my money wisely.  Why cant there be a 295/57.5-20?
