I would imagine this is going to become a bit of an area of contention. 235/65 is at least an inch upgrade. The one's I'm putting on are 29.17". It'll be interesting to see my fit, because I am also increasing the wheel to 17x8.5, and it'll be moving close to an inch toward the back, and poke out a full inch. We'll see what happens.
From CarsonB::
"Update on if the 235/65/17 tires fit.
I got them installed this week, specifically the Hankook Dynapro RF10 and no rubbing issues so far. In terms of Fuel economy, I have noticed the MPG is worse during accelerating but once you get up to speed its barely worse than stock. Road noise is the same as stock. It's pretty close to the strut perch so my only concern is it will catch a little if snow/ice gets on the tires but other than that it should be fine. The key issue I have noticed from so many people complaining that their tires wont fit is because they are all running spacers. I don't think that many people realize that spacers actually make your cars tire sweep out a larger arc therefore causing it to hit the fender well. It makes it look cool but I don't want to chop up my car for 1" extra of poking out, not to mention I would think that the tires would make the car less aerodynamic because the wheels stick out past flush with the side of the car therefore causing significant MPG drops.
My setup is stock wheels on a non lifted trailhawk. I can post pictures later if people are interested."
There is another a couple pages later, who cut out the inside of the Fenders, but he used 30mm spacers. He also didn't necessarily say he needed to do it.

Thank you for posting this!
I haven talked about wheel spacers quite a few times on here, and will do so again.
Wheel spacers are NOT a good idea.
Using wheel spacers means you are taking something that used to use steel on steel (with a thin layer of aluminum in between) being steel lugs to steel hub, sandwiching an aluminum wheel hub. If using spacers, you are then bolting a soft aluminum "donut" to a steel hub (weak point)… then bolting a steel wheel (separately) to that soft aluminum donut (yet another weak point)… and expecting it to hold up like steel on steel would??
Add to that... you've now added wheel arc (tires have to swing out side to side AS WELL AS front to back, just to do the same action as a stock set up's "pivot").
Add to that... That arc (since it makes your tires move FORWARD/BACKWARD more) will now contact your tires with the wheel well (creating yet another problem, on top of all the others).
Add to that... those wheel spacers now add that much more leverage on your wheel bearings/suspension that was NOT there before.
Is THAT worth the "cool" look of pushing your tires out 1-2"? NO.
Now people will jump on here and say "yeah, well they've been using wheel spacers forever and many have been just fine!". Yep... and many have NOT (google reports of wheel spacer issues).
Wheel spacers are NEVER acceptable. NEVER. If anything, use more wheel offset wheels. That will eliminate the "spacer" issues, but will still leave you with the arc issues (wheel well contact, front/back sweep, bearing load, suspension load), but at least your wheel won't fall off, and kill you, as you're going down the highway at 75.
I started off roading 27 years ago. I have NEVER, and will NEVER use wheel spacers and cannot stress enough how bad of an idea they are.
Sorry for the rant... but had to get that off my chest
