You probably will get rubbing from that fitment, it's too big. The stock tyre is 215/60/16 and the one you have is a bit taller. Can you be a bit more specific as to where the rubbing is? Arches. struts etc? Generally when someone is fitting off road or heavy tyres with a higher sidewall (70/75 profile) they put them on 15" rims and it would be a 205 section (205/70/15) to keep the diameter close. I would imagine your local shop should have pointed this out to to you. The speedo will now be out as well, a reading of 100k/mh will be closer to 107k/mh, if that's important.

I made a boo boo on the last reply, what I meant was when you are doing 107km/h on the new boots, your speedo will show 100km/h. I guess the relevance of that depends on the local Police. Unfortunately spacers will only help with the strut rubbing and could likely move the sidewall to a position where it contacts the arch (although a 3-5mm spacer should be ok). The problem with contact on the mud flap is caused by the increased diameter and short of cutting the body work (no) there really isn't much of a way around that short of removing the flaps, but other areas may then show up.

this is from
Plus One Tyre Sizing: Learn How To Plus Size Tyres & Wheels
covering Victoria.
Find the link on the page to Victoria.
Contained within is....
The overall diameter of any tyre fitted to a passenger car or passenger car derivative must not
be more than 15mm larger or 26mm smaller than that of any tyre designated by the vehicle
manufacturer for that model.
The overall diameter of any tyre fitted to:
 4WD passenger vehicles specifically designed for off-road use (typically MC ADR
category). All wheel drive (AWD) vehicles including those AWD vehicles that may be
certified as MC ADR category, (also commonly known as soft roaders) are not
included in this category;
 4WD goods vehicles and their 2WD equivalents if the chassis and running gear are
essentially the same as the 4WD version (N ADR category); or
 any medium weight goods vehicle (NA2, NB ADR category).
Must not be more than 50mm larger or 26mm smaller than that of any tyre designated by the
vehicle manufacturer for that vehicle.
Note: Increases in tyre diameter are subject to compliance with all other requirements
specified under this clause (Clause 4.2 Non-Standard Tyres and Rims) and may
therefore be limited by other factors such as insufficient clearance.
Speedometer accuracy must be maintained for the selected tyre and rim combination to within
the degree of accuracy specified in ADR 18 where applicable. It is suggested that the degree of
accuracy is in accordance with the most recent version of ADR18.

My records show your model Forester GT was equipped with 215 60 R16 tyres.
Now, fitting 215 70 R16 tyres has altered the rolling diameter by 46mm which is larger than the specified 15mm.
The 2 inch increase limit does not apply to light SUVs only for full blown off road 4WD.

So, you have given Constable Plod all he needs to issue a defective vehicle notice and your insurance company all they need to decline a claim should you need to make one.

Your tyres foul the suspension and do not fit properly. Please consider reverting back to a standard tyre?

ok i have a 45mm lift from kingspring's = NOT un roadworthy
215/70r16 = no longer rubbing due to putting SG forester rear struts in ( if you cant tell the difference unless you look at the part numbers stamped on the strut) and on the front was just a matter of removing front mud guards.

215/60r16 = 664.4
215/70r16 = 707.4
so that gives a difference of 43mm "Must not be more than 50mm larger" self explanatory. car goes where the big boys go!!!! :)

as with the speedo 100km/hr on speedo is 106.47km/h but has been fixed buy Speedo Corrector MkII Kit - Jaycar Electronics speedo corrector so when my speedo reads 100 I am doing 97km/h (GPS cheeked with 4 different apps and 3 different gps units)

as for when i get pulled over by MR POLICE well IF he knows his Law's I will be fine. If not i will get my defect notice and then go to work and get a RWC.
but honestly mate i think the car handles better with new tread than the slicks i was on!! to go back to 215/60r16 find me some real all terrains that are under $200 and I will keep them in mind for next year :)

The SF suspension has a lower spring perch than SG suspension. 215/70 R16 will fit fine on SG suspension (I've been running this size for YEARS, and never had rubbing). Since you are using SF suspension, it can rub. I would look into either "modifying" your suspension with a hammer and smacking that spring perch a bit to have them clear, or get yourself SG struts (may be easier to find used as you need the top hats, spring and strut). They bolt on, you'll get a little extra height out of them, and they ride nicer.

Or get a set of 15" rims and put your 205/70/15 or 205/75/15 (which is 39mm taller) profile dirt boots on those, save your alloys from the beating and likely breakage they will get in the muck if you are looking at some off roading but if they are permanent fit then the rest is up to you.

I am surprised to hear 01gt say his Foz handles better on studded than road tyres, is that on tarmac? There were BFG All Terrain boots on an Isuzu Trooper I bought many years ago which were dangerous on a damp road but particularly in the wet even though there was around 7-8mm tread. Also, the heavy tread pattern generated excessive noise and vibration although I wasn't aware how bad until I put road tyres on it. A friend who had the same model with the BFGs ATs allowed me to compare them, he was surprised too at the excessive noise above 30mph. Even with the tarmac boots I never had any trouble getting grip on the dirt except one occasion where I got stuck in sand and dropped the pressure down to about 6PSI which worked a treat. However, those were a different type of tyre so comparison is not fair.

If you are going to be using heavy tread rubbers on the tarmac, the increased noise and vibration on longer journeys at highway speeds might be something to consider because it can cause fatigue more quickly, if they are your full time tyres. I find my Forester doesn't tolerate cheap boots. The set I fitted when I bought the car were generic whatever brand because cash was short but they weren't cheapies either. I put up with them for about three months and then bought a set of Avon ZV5 which were more costly but the back of the car is now more willing to follow the front through corners especially in the rain, less wheel spinning, more comfort and less noise too. In general, tyres are often a subjective choice so see if you can find anyone in your locality with a Foz on HD rubber and ask them what they think.

The link below will help define what rubbers fit what rims. Put your stock size in on the left column (I've entered the OEM wheel size for your car) and then try out whatever you are interested in the right one and it will tell you about diameter, circumference and speedo correction.
