      18" wheels and AT tires on a SPA XC60 T8

      Hello there folks, picked up my Fusion Red XC60 T8 just a couple weeks ago and we're totally loving it. The Mrs and I are looking forward to some serious road trips and off-road trips in 2019, so some real tires were the first order of business... Unlike the XC90s, as best I could tell all the 60s have the same brake rotors and calipers, so I was reasonably sure 18" wheels would fit and sure enough they did:




      Funny how silly the stock 21"s look in comparison lol...FWIW those are MSW Type 49s, 18x8" with a +42mm offset, wearing 255/55-18 BFG A/T KO2s.

      Those AT tires look amazing! I was pretty happy with the more aggressive look my winter tires gave my T8, but this is a whole new level!

      I personally love the look of both the street tires and the ATs. Very different looks, but both are great.

      Those look awesome.

      The width going to be an issue or at the wheels on the 21" the same? You probably have the fender extensions?

      > I gotta think those are going to be pretty noisy!

      Well, let's say it's not bad? :-P
      On most road surfaces it's no louder than the electric motor whine though obviously a different pitch, so yes it is noticeable. I doubt the actual DB level in the cabin changed, but will test that with a DB meter in due course...
      If as the tires age they get louder, I do still have my 21s I can run and just save the 18" AT tires for snow and OR trips.

      > The width going to be an issue or at the wheels on the 21" the same? You probably have the fender extensions?

      No fender extensions or anything no, not at all required. The stock 21s are 255/40-21, and the 22s are 265/35-22, so 255/55-18s were not a problem from a tread width or tire diameter standpoint. The tire installers were a little worried that the more bulgy and knobby sidewalls might rub the upright, but it proved to clear okay.

      The stock 21's (255) already have a small OEM fender lip extension in the wheel well. When installing 22's (265), the wheel well lip is removed and not reused (https://accessories.volvocars.com/In...C60(18-)/2018).

      Honestly, though, I'd run the 22" fender extensions with off-road tires. That tread will sling mud all over your car.

      Link doesn't work but interesting, didn't realize those little plastic strips on the front arches are part of the 21" package, ty.

      Oh wait, I see, interesting...the 21s have the little black plastic lip extension, while the 22s have what I presume are larger body colored extensions:

      Need to go find pictures of those 22" extensions, might want to get those...

      Love it! How does it handle with the 18s both off and on road?

      Did some off-roading on my stock 20’s last weekend up in Big Bear, CA. Got to test off-road mode on air suspension and it handled exceptionally; but I bet your setup would be much better. Got some funny looks from a couple of Jeep groups but we just smiled and waved.

      On road traction is great but you can feel the tall tread blocks and sidewalls being a little squeamish if you push it hard, when turning at low speeds you can feel the blocks going thup thup thup on the pavement, and there certainly is a little bit of hum and mid to higher speeds (It's noticeable, but I doubt actually any louder than normal from a DB standpoint, will test that in due course).

      Off road they were fantastic, did a 10 mile loop on the gravel road you see here in AWD Mode and the ESC never lit up even once. Ride when in full Off Road Mode is very stiff because the air springs are maxed out, but airing the tires down would help that a lot (I run them pretty high, 45PSI, helps reduce pavement hum).

      Don't know how you made it work....
      Wanted to install my 18" wheels with winter tires on my new 2019 and it was a no go. The rims barely cleared the caliper. Installer could not add the balancing weights on the wheels as those would hit the calipers. I am wondering if this is because I have the R-design and it may have different calipers ....

      T6/T8 have the same rotor/caliper size.

      I bought a cheap 18" alloy wheel (not rim) as a spare tire off TireRack and it barely (1/8") clears the caliper, but it works so I kept it.

      My T8 is a R-Design as well...I would suspect it comes down to the individual shape of the wheel face, I'll take a detailed pic for you.

      I had 18" wheels too. They worked perfectly on my XC60 2017. When mounted on the 2019 version without the balancing weights, they also cleared 1/8" from the calipers. Unless your wheels do not need balancing (hard to believe all 4 of them would not need it though....), I really didn't see how this could work. Now, don't get me wrong- I'm not saying it didn't work for you - it just didn't work for me, with my set of wheels. I even asked the tire shop to use thinner balancing weights, and even with those, they were rubbing against the calipers.
      I personally think it would be a risk to drive this way as the caliper and wheel could get jammed and throw the car out of control. Had to order new 19" wheels...
      I will be selling my 18" winter wheel set.

      Sorry folks, big pics, hope they tell 1,000 words:






      So looks like even though the wheel weights on the face side of the wheel were stuck right there at the highest point of the rim surface they still don't conflict with the caliper.

      YMMV...

      I got 19" wheels for 2018 XC60 T8 and the weights rubbed at first. Had the tire place re-balance them with the weights as far in as they could ( towards the center of the car). They no longer rubbed the calipers are only on the outside of the wheel.

      The T8 has stricter restrictions because of the additional electrical engines. As to positioning the balancing weights further in the rim, I asked my installer to do it and they said they can't because that is not recommended/legal. Need someone to check the rotational physics on this to know if this is true or not ....
      I am getting my 19" wheels next week, so they should work on a T6. Will post photos.

      18" wheels and AT tires on a SPA XC60 T8

      Love the wheels! Did you buy them local or online? If online, would you mind letting us know where?

      Also, are those painted gunmetal?

      While I found and selected the rims via Tirerack, I actually purchased them through my local America's Tire Co. shop that did all the fitment work. Linky: https://www.tirerack.com/upgrade_gar...nmetal+Painted

      if tire installer had spun tire 180 deg. around the rim, then most likely there would be a lot less balancing weights added.

      Planning to purchase this exact setup right now for my T8 - what did you do for TPMS, re-use existing or new? Thanks for the excellent inspiration!

      There isn't any tpms sensors, as far as I understand. I purchased winter wheels and tires when the car first came out and tire rack didn't know what sensor to use, so I had them put in xc90 sensors. Found out later they aren't needed. The car uses the abs wheel speed sensors to detect a change in tire speed from a decrease in pressure. That's why your supposed to inflate your tires to the correct pressure and then go into the menus and have it "relearn" the tires pressures.

      That's a VERY tight fit.. Any dirt accumulated on the inside of the rim WILL rub the calipers.. Plus I'd question how's brake cooling with such a setup.. But to each his own I suppose..

      Can't say I'm significantly worried about those things, remember a Momentum T5 comes with 18s as standard and as best I've been able to find all the XC60s have exactly the same brake package.

      What I _am_ worried about is when significantly off in the wilds doing something stupid and bending a rim enough it won't spin. THAT would suck, Death Valley has it's name for a reason eh? :-P
      Which is why I selected rims that were not on the super light weight end of the spectrum and looked to have a strong spoke profile ('looking' strong isn't a great measure but it's better than nothing), and I have a tow hitch mount full sized spare carrier.

      Two front brake sizes can be found on the XC60- 322 mm or 345 mm.

      You must account for rim shape/design and offset when it comes to brake clearance..

      Indeed I see the two sizes, but those show up on all engine levels...maybe some markets have the larger and some smaller? It's not really explained:
      https://www.media.volvocars.com/glob...specifications

      FWIW, C&D's spec site says 13.6" (345mm) for all US models, so looks like we all get the nice brakes:
      https://www.caranddriver.com/volvo/x...60_2019/401789

      And yes absolutely the inner face of the wheel is critical to clearance, people looking to do the 18" thing should talk to Tire Rack or their wheel/tire specialist and talk their way into cost free test fitments, or of course just find a set of the OEM Volvo 18" wheels.

      Looks fantastic, and perfect timing for the Polar Vortex snows!
      How's it handling the slippery stuff?

      I have a question, if anyone who has researched this stuff can help me figure out the answer. I have a set of Volvo OEM 18x8 wheels, style 233 (offset +42.5 mm), that I have been using with Nokian Hakka R2s, (235/60 R18) on my 2016 XC90 t6 for the last three winters. They work fine on the XC90.

      Does anyone know if I got a 2018 XC60 T8 if I would be able to use them on a twin engine XC60 (currently fitted with 19s)? It seems Kranvagn was able to do 18s on his T8 XC 60 without a problem.

      I guess my specific questions is: Is there a difference in brake rotor size, or in anything affecting wheel compatibility, between a 2018 XC60 T8 and a 2016 XC90 T6? If anyone has any experience/insight, it would be very much appreciated. I am very far from an expert on wheel and tire sizes.

      Thanks.
