First post (woohoo)

Well I bought myself some dynapro atms' 235/65/17 for my 2015 subaru forester. I went to the local "big o tires" shop and drop her off and run some errands with the ol' lady.

An hour or two goes by and they call and say that they will not fit. They tried to tell me that the clearance with my current tires is less than half an inch of clearance and all this yada yada.

I open my trunk and can tell they never even pulled a tire out or even attempted to see what can or can't fit.

So my question is.

While my subi currently is sitting on 225/60/17, the tires look PUNY and have a large amount of clearance including around the strut housing. I am dumb in assuming that the 235/65/17 dynapro atm's will fit no problem? I am thinking that I just happened to get a lazy person waiting for their friday to end or something. I just don't want to take the sub and the new tires to another tire shop and end up with the same issue.

Will they not put larger tires on a car if it is larger than the oem recommendation in their computers?

If I thought they lied to me, I'd go somewhere else. I asked someone at discount about tire in same size.. They told me they weren't sure if it would fit or rub, but would gladly mount them and try

The Forester has 17 x 7J (7" rim width) wheels

Maximum tyre width for a 7" rim is 225mm

When in doubt, ask the dealer's service or part dept.

I have heard "online" about many people running this tire with zero issues. Just trying to see if I will have the same exact situation happen again. I am thinking of just pulling all the tires and taking the tires/rims in and just put them on myself and skip the issues. Plus if there is any rubbing etc I can bang and cut at it while at home versus dealing with it at the tire shop or driving down the road.

If anyone is running the 235/65/17 on their forester and have zero problems feel free to post about your experiences whether good or bad.

I have only heard of one other person who had a shop tell them they would not install them but that was just due to their comp saying they would not fit.

it will also matter what your rim offset is. a smaller positive offset (ie, +40 instead of +48 (stk)) helps to place the tire more outboard instead of closer inboard toward the strut assy. another concern is the tire clearance to the front Lower Control Arm (LCA) when the steering has been turned to full lock, left or right. this clearance varies on whether or not the car is moving fwd or reverse, during full lock. this tire-LCA clearance varies by just about 1"! see for yourself in a parking lot. it's quite disturbing how crappy of a bushing design subaru implemented in the LCA.

yeah the rim offset does matter. I think +40 and lower is the preferred offset when i researched it here. (I think there was a debate going on with offset in the thread i found)
I honestly tried 235/65/17 yokohama geo g015. Fronts fit, the rears did not. Hit heavy on the wheel well.
My local discount tire tried it on the 17x8 rims I got for the vehicle. Hit heavy when it was up on the lift. Even heavier when they dropped it to the floor.
So I decided to go 235/60/17. Not as tall as 235/65/17 butt works for me.
Here is a pic of how close the rear tires are to the wheel well

Doesn't it mess up your eyesight system?

from what i've read on various posts (because everything's true on the internet), a 1" lowering or raising of ride height still allows the Eyesight to function properly. i have Eyesight issues even with my current 100% stock setup.

i myself, am looking at 225/65/17 BFG AT KO2 tires on 17x7.5, +40 wheels, and Mann Engineering 1" Lift Springs. should work since LP Adventures states their 2" Lift Kit (spacers) + 225/65/17 tires are still compatible with Subaru Eyesight.

i take it your suspension is stock? yes, that clearance to the front part of the rear wheel well is a concern of mine too. i'll be switching to 225/65/17 BFG KO2, on 17x7.5, +40 rims & Mann Engineering 1" Lift Springs.

the LP Adventure 2" Lift Kit spacers insert between the rear subframe and chassis, so this rear suspension linkage articulation clearance issue is mitigated. but, i personally don't like their rear subframe spacer kit. IMO, the spacers don't keep the rear subframe fasteners in the same load condition as the stock configuration.

 

[88maroon]

No i recently got the ADF 1" front and 1 3/8" rear strut spacers installed before trying 235/65/17 on 17x8 +40 offset.
I knew it would rub, but didnt think it would rub/hit the hard. The front wheels looked great. Hit a little when we had the steering wheel turned all the way which was expected. Just how hard the rear wheel hit the wheel well was a surprised to me.
I think getting strut spacers or i think for my model multilink spacers would help with putting the rear wheel centered in the wheel.
But that is another set up in the future and i would probably trim/grind some stuff in the wheel well before even trying 235/65/17 again.

 

[duckboy]

i guess some of the clearance loss comes from the rear subframe to frame bushing compliance. i think someone sells a rear subframe bushing insert that fills the bushing voids to help reduce bushing compliance. i think whiteline makes a set.

A lot of tire shops will not touch any other tire size than what is on the door. For liability reasons.

I usually end up bringing them to the tire shop off of the car so they don't know what they are going on. Or, if they ask, I figure out what size vehicle has that size from the factory and just say it's for that.

 

[Canada2018]

There are a few that have put them on here https://www.subaruforester.org/vbulletin/f72/will-235-65r17-hankook-dyapros-fit-784901/

 

[holmesbr2]

Check with the car racers in your area. They will know who will mount what. One of them may even have a tire machine. Dropping off wheels and tires and picking up next day mounted and balanced is nice. Usually cheaper than a tire shop.

Alright so it has been a minute BUT my buddy is a shop manager and said he will see if they fit. They fit perfect and clear everything. I have stock rims on my 2015 forester and I have zero rub anywhere. I took pics and will post them once they upload. 235 65 17 dynapro atms on stock forester 17" rims.

Thanks for sharing...super helpful! Anyone w a stock SJ try this with the new Cooper Discoverer AT3 4S in 235/65R17? Would like to get a sense of that specific tire model rubbing on a stock SJ. Thanks.

I'm running wildpeak 235/65/17 with Method 502 offset +15. No rubbing
