Different tire sizes

[JumpMan]

Might be a dumb question, but what size tires can I fit on stock wheels, at rock ride height.

No leveling kit, or lift kit.

strictly replacing tires with KO3’s. Looking to do 285/70/R17 to replace the stock 255/70/R17 without having to do a lift.

Following. I did a 2.5inch level though and want that size KO3 on stock wheels

I searched the older posts but found nothing definitive. I have a 2025 Ranger XLT that came with 255/65R18's. Can I put 265/65R18's on without any problems with stock height? Thanks.

I put a 2.5" level on mine and am running 275/70r17 on a +25 offset wheel. They fit very well, but clearance at full lock is very tight on the front wheels. Im glad I didn't go with 285 as I'm not sure they would have fit without rubbing or trimming.

At stock offset you would have a bit more room. I think people run 285/70r17 at stock offset with a level, but not sure about fitment without the level.

Is this correct? I was under the impression that to run 285's you'd need at least a level AND +35 offset, and that the stock +55 offset wouldn't work with tires that big. I'm not trying to disagree with you, I just want to understand because I plan to go to bigger tires and want to make sure I have the correct (or adequate) offset.

All the info related to my fitment is 100% firsthand and correct.

The other info isn't firsthand, but if you search the forum you will find people running 285 on the stock offset with a level. I can't verify that fitment firsthand though and also can't speak to whether they have removed or modified crash bars (I haven't). Rub also depends on how hard you are driving it.

Based on all the research I have been doing the past several days. I have no doubt at all that a 265/65R18 would fit perfectly fine, with no rubbing or issues at all.
I think the 275/65R18 is lis looking like where the limit is for max and not rubbing.

I have found some info on 285s fitting but it starts to get really iffy on clearance of the UCAs.
Some say spacers are needed some say they clear without spacers. I honestly think it would come down to the true spec of the 285 tires chosen. There is always some variance in actual spec compared to the stated sizes. Meaning not all 285s measure a true 285mm some a little more some a little less, and actual tread width can vary wildly.
Ie.
My Raptors came with 285 BFGs and I am running Falken 285s. They both state they are 285s but the BFGs have nearly an inch narrower tread width than the Falkens.

I went with the 265's.

Cool !
Would you happen to have any pics you could share?

When trying to decide on different combinations I find it really helpful to study picks of different combinations. I have not found any pics yet of 265/65R18s on a 6th gen Ranger.

Ready lift sells a 1.5” level and mentions in the fine print that 285/70/17 will only fit with their level after trimming and that stock wheels won’t clear a 285. I would go 265/70/17

Do you have any pic's to share? TIA

I found these pics just now in an open google search of a 6g Ranger with 265/65R18s.
Better then stock 255/65R18s but still maybe a little smaller then what I was shooting for.
‘Could just be the nature of the BFGs, they tend to be narrower then most where tread width is concerned.
