I thought it might be a good idea to make a FYI thread regarding tires for our cars (several members have mentioned this). Note that this thread is info that I have stolen from YOU guys and tirerack. If I get anything wrong please don't feel shy to post corrections and I will post them on this first page. I want this first page to be a place where people can find facts regarding sizes they can fit on the Global Platform Imp. In the thread following please post photos of non-stock rims you have bought INCLUDING the size info (thanks).


From Tire Rack, TPMS frequency is 433MHz

Bolt pattern = 5x100, +55 offset.

Wheel nut tightening torque: 89 lbf·ft (120 N·m, 12 kgf·m)*
*: This torque is equivalent to applying approximately 88 to 110 lbf (40 to 50 kgf) at the end of the wheel nut wrench.

Stock sizes:
Premium: 16" 206/55-16 width= 6.5"
Limited: 17" 205/50-17 width = 7"
Sport: 18" 225/40-18 width = 7.5"

Rim and Tire Size Calculator: https://www.wheel-size.com/calc/

Things to remember, the SPORT model has LARGER front brakes (rims and calipers) sport rotor size is 11.6" in diameter compared to every other models 10.9" up front but the rears are all the same at 10.8". People HAVE put smaller rims on the sport and bought larger diameter tires so as not to mess up their speedo readings.

Another thing to remember; if you are new to Subaru remember that if one of your tires needs to be tossed due to damage then you will have to do one of the following; buy ALL new tires or have a tire specialist match the new tire diameter to the ones you have (they do this by removing rubber on the new tire). This has something to do with the AWD system, if the tires are not the same size (or very close) it can ruin your AWD system. (not going to pretend to know how this works but it is a fact).

One of our members put 16" rims on his Sport Model, the clearance is VERY tight to the brake, his comment "Verdict: the 16" wheels I got from Tire Rack (16X7.5 SPORT EDITION P3 ANTHRACITE) fit on the fronts, but with a mere 4.5mm clearance between the caliper and the part of the wheel where the weights are applied."

Can you put rims from older Subies on your new Impreza? Comment from a member: "I just put 205/55/16s on my sport, plenty of brake clearance, handles as expected with snow tires. Steel wheels (16x6.5) w/General Artic Altimax, they were from my 2014 Impreza."

Can you put Crosstrek wheels/tires on my Imp? Comment from a member: "I put 2015 Crosstrek wheels my Sport today The wheels are 17 x 7 and they fit fine."

Rims from a WRX WILL fit our cars unless they are 2015 or newer.

Another great wheel/tire calculator (thanks BuzzBomb). tiresize.com/wheel-offset-calculator

Listen, I am NO mechanic so PLEASE tell me if something needs to be added to this list or if anything is wrong. Thanks. :wink2:

Maybe add offset? I believe it's +55 for the sport 18s but not sure if it's the same across all trims - or Canada for that matter.

Add torque specs since the question came up. This is pretty much copy/paste from owner's manual...

Wheel nut tightening torque: 89 lbf·ft (120 N·m, 12 kgf·m)*
*: This torque is equivalent to applying approximately 88 to 110 lbf (40 to 50 kgf) at the end of the wheel nut wrench.

Great info! Actually I just got a set of Sparco Asseto Garas for my Premium.

Here's something that could be useful to add too...

From Tire Rack, TPMS frequency is 433MHz
From this site, http://www.impreza5.com/forum/130-5th-gen-impreza-maintenance-service/3649-rotating-tires-tpms.html , it sounds like the TPMs have to be reset every time the tires are rotated (although the answers there didn't directly say if that was the case). It also sounded like some shops with older TPMs tools will have trouble recognizing the TPMS without the most up to date software.

I could be misreading that TPM tread though.

Thank you sir! :) I am going to add the part that you know for sure.

You have no idea how grateful I am to have stumbled upon this. I've been wondering about all this information for the last few weeks while looking for snow tires/rims. Thanks!

Minor correction needed to this:

Premium: 16" 206/55-16 width= 6.5"

Base is also this size and it should be 205 instead of 206. You can delete this post after the update.

After switching to my winter tires today I notice on the invoice a note saying "Alignment recommended after new tires installed". Do you guys do this after new winter tires are installed on your car?

If the car is driving straight and the tires you just took off show no abnormal wear I’d just leave it alone. The only time I do an alignment is if the car starts pulling to one side or the tire wear is uneven.

That's a good info source. I'm just letting you know you have a typo, because your original post said to let you know if something is wrong.

No, not if the tires are essentially the same diameter.

I found these on Ebay: https://www.ebay.com/itm/362370444704?ViewItem=&item=362370444704

The thing is, when you punch in any 2017 model it claims that they do NOT fit. I wonder if it is wrong? I contacted the seller, will see what they say. The sellers ad says they will fit but the Ebay fitment guide says they will not fit.

This would be a nice cheap way for many of us to have a set of snows.

May be add this to the summary? from manual section 9-3

The temporary spare tire must be used
only on a rear wheel. If a front wheel tire
gets punctured, replace the wheel with a
rear wheel and install the temporary spare
tire in place of the removed rear wheel.
