25 OT Larger Tire Fit

[Caraddictionisreal]

What is the largest tire size anyone has fit on a stock 2025 OT or OT+? I have a 24 OT with the Westcott kit and 285/75r17s (34s) with almost no rub. I have a 25 OT on order (we'll see how the tariff treats me) and am hoping to fit the same size on a stock (no lift) 25.

Great question, I just picked up my 25 OT+.

I haven't dived too deep into this thread but pour a cocktail and enjoy...

From experience I would say 285/70R17 or 285/70R18. I was informed that 285/75R17 would be the largest tire that would not rub, but I have discovered that indeed it is not the case. Basically, at full turn the front tires rub the rear lining and the bracket. I ended up removing the liner...

would love to know this as well... wondering if 35s would fit now?

if you had to modify with the higher westcott lift to fit 35's, 1" is not gonna do anything different.

I’ve heard some say 285/70r18 will fit, but I went with 275 Nitto Terra Grappler G3’s since it was the largest size in an SL rating. No lift or rub

Curious if anyone with a 25 OT has tried this yet. Not looking to lift stock suspension but would like to upgrade tires. Considering 285/70/R18 on stock wheels or try a 34" setup with 17" wheels if the 35" still requires modification.

I’d say 34” depends on the offset of your rims but it’ll be close and will vary based on tire choice. 34” may also not fit in the spare location if having a usable spare matters.

What affect/impact to vehicle warranty does these tires/wheels/suspension changes have?

 

[munkeeboi]

magnuson moss act. Manufacturers must prove that a specific modification directly contributed to the failure of a component to deny warranty coverage

I did 275/65/r20, stock 25 OT+
no additional lift, Toyota Sequoia 20" wheels

Plan on going 285/70 on stock OT when the OEMs die
