20x9 or 20x10

Good choice!

 

I don't have that exact wheel myself, but I have the same specs 17" x 9" with a -12mm offset.
You WILL rub the tire on the fenders. Trimming is easy to do as long as your open to it. If you take your time doing it will barely be noticeable that anything is different.
That fitment also yields 4.5" BS so you'll have the room for 33" tires down the road if you ever want to up size.

Here's my truck on 285/70-17 tires and 17" x 9" wheels with -12mm offset to give you an idea how they look -



Another thing to keep in mind is 9" is wide, a lot of 265 sized tires won't mount to a 9" wide wheel. Check the tire specs you want first to make sure that combination will work.

Being that you're looking at 265 sized tires your rubbing and trimming will be minimal, but I do want to stress that there may be some.

 

@eccracer104 so the trimming would be necessary on the fenders or something else?

 

Mostly just to the black plastic inner fender liner. The amount of rubbing and trimming required varies dependent on the alignment numbers (caster mostly) so it's hard to say exactly what will need to be trimmed. More often it's the black plastic inner fender liner in the front and back of the front wheel well. Also possibly a little of the rear bottom edge of the fender.

Eventually if you choose to go to 285 sized tires you'll more than likely need to flatten your pinch weld and do the CMC to alleviate the rubbing.

 

@eccracer104 i appreciate your help. One last question. I was also looking at the ultra crusher 17x8 +10 offset seems to be a cheaper alternative with a narrower wheel but a positive offset. Any more knowledge on those?

 

It's all numbers and measurements, easy to give input. 17x8 with +10mm offset will work perfectly with 265/70-17 tires, however it won't leave the room to upgrade in the future. You'd need a wheel spacer if you ever wanted to go up to a 285. With 17x8 and +10mm offset I highly doubt you'd rub anywhere with 265 sized tires.

This is what 265/70-17 on a stock wheel (17x7.5 +30mm) looks like compared to 265/70-17 on a 17x8 +10mm offset wheel.


Here is stock against the 17x9 -12mm offset -



This is a fun tool to use to better understand how all those numbers play a role in the fitment of aftermarket wheels -

 

@eccracer104 much appreciated

 

ive seen 235s mounted on a 9 inch wide rim. im sure 265 will be fine

 

You are more than welcome to install whatever you want on whatever. However, check this out -


I picked the go-to AT tire for half of TW. A C load range 265/70-17 BFG KO2.

Do you see where it says "rim width range" this is the safe and recommended rim width that this tire can be mounted too. I will not recommend anyone to mount a tire to a rim that's too wide or too narrow.

Now I did mention "a lot of 265 tires won't mount a 9" wide wheel" I didn't say all 265 sized tires wont fit, there are some that will like this P rated Firestone destination -



This tire is 100% safe onto a 9" wide wheel.

 

I bet every 265 tire would fit fine on a 9 inch rim. hell im running that setup right now

 

You're your own person, do whatever you want.

Here's some more manufacturers that also list up to 8.5" wide. I'd be willing to bet their R&D is more accurate than your assumption.

Toyo AT2


Cooper ST MAXX


Bridgestone Dueler Revo 2



Again, there are tires out there that WILL fit a 9" width in 265/70-17, just check before hand to make sure it does fit. Typically it's only the P rated tires.

 

you do know that's recommendations.

 

Correct.

Cars and trucks stretch tires all the time, I'm not saying they won't fit. I only said to check the specs and from there if either yourself, OP, or anyone reading this wants to exceed that recommendation at least they know.
