So i’ve been researching what winter wheels/tires i can get for my type S this fall and im finding that there is zero fitment info anywhere. Almost no sites have type S as a wheel fitment option so i thought maybe someone with a better underatanding then me could explain if my math is correct on this, and hopefully it will assist some other owners as well. Im looking to go down a size to 19’s for the winter…
stock wheels
5x120, 9x20, et 50, center bore 64.1
mm breakdown…
Wheel width =9x25.4= 228.6mm
centre of wheel = 228.6/2= 114.3
hub to outer face of rim = 114.3-50= 64.3mm(center of wheel minus et)
hub to inner edge of rim= 228.6-64.3=164.3mm (wheel width minus hub to outer face of rim measurement)
im finding very few options in the same 9” width (these are winter wheels, they need to look good but im not spending the money on vossens or some high end brand to drive them through salt covered roads) in a 19” wheel. The only options available being 8.5” or 9.5” with et from 35 to 45. Here are the measurements on the wheels i’ve looked at…
19x8.5, et 45
Wheel width =8.5x25.4= 215.9mm
centre of wheel = 215.9mm/2= 107.95
hub to outer face of rim = 107.95-45= 62.95mm
hub to inner edge of rim= 215.9-62.95=152.9mm
hub to face change = -1.35mm
hub to inner edge change = -11.35
this would imply that the face of this wheel would sit 1.35mm closer to the hub then stock. With the stock wheels being extremely close to the caliper to begin with (and the car generally looking like the wheels are a bit too “sucked in”) i would say this fitment is not a safe choice.
19x 8.5, et 42
Wheel width =215.9mm
centre of wheel = 107.95
hub to outer face of rim = 65.95
hub to inner edge of rim= 149.95
hub to face change = +1.65mm
hub to inner edge change = -14.35mm
an increase in the hub to face but not enough for me to comfortably say it will fit as the measurement is based on the distance of the face of the wheel, not the back side of the spokes of the wheel. Its too close to take the chance.
19x 8.5, et 35
Wheel width =215.9mm
centre of wheel = 107.95
hub to outer face of rim = 72.95
hub to inner edge of rim= 142.95
hub to face change = +8.65mm
hub to inner edge change = -21.35
this option has what i would consider almost ideal hub to face change, but the 21.35mm (meaning the inside edge of the two front or two rear tires would now be 42.7mm further apart then stock) is too much in my opinion and maybhave too much of an effect on scrub radius.
19x 9.5, et 40
Wheel width =241.3mm
centre of wheel = 120.65
hub to outer face of rim = 80.65
hub to inner edge of rim= 160.65
hub to face change = +16.35
hub to inner edge change = -3.65mm
An increase of 16.35mm from hub to face would be too aggressively “stanced” at stock height for me but some may like it and it should clear the brake calipers no problem.
19x 9.5, et 45
Wheel width =9.5x25.4= 241.3mm
centre of wheel = 241.3mm/2= 120.65
hub to outer face of rim = 120.65-45= 75.65mm
hub to inner edge of rim= 241.3-75.65=165.65mm
hub to face change = +11.35
hub to inner edge change = +1.35
this size of wheel would be 11.35mm (75.65-64.3) further out from the hub then stock and 1.35mm further in to the wheel well, as in closer to the suspension then stock (165.65-164.3). To me this would seem the safest as the increase in hub to face distance should make clearing the caliper no problem, with little change to the inside fitment.
so basically what all this means is that since i cant find a 19x9 wheel that i like, it seems like the best option for fitment would be 19x9.5 et 45, although 11.35mm hub to face is probably more then i would like, any less at 9.5” width would start encroaching on the suspension more then id be comfortable with.
Does all this look correct to someone who is knowledgeable on the subject? Im likely ordering on-line with tires installed and i really dont want to screw it up.
Vossen makes a lot of high-offset wheels specifically for Honda/Acura applications. They may be working on one or more wheels that are compatible with the TLX Type-S specs.

They do and are orderable. The HF5 and HF1's are good looking...IMHO....and cost $750 each for the Type S sizing...not counting opt. special order center caps. BBS has a wheel...SX...that has a 42 mm offset.
Still hard to find out IF they will fit and clear. It's cheaper than the Vossen's. Also, Enkei just came out with a 20 x 9 wheel....it's 9 1/2" wide and has a 40 mm offset. $420.
Go to "Fitment Industries" and you'll find lots of wheels. The BBS SX's....machined/gray...look nice....are $1980 for the set. Again....fitment is still being determined. Personally I don't like using
spacers....or centering rings...but, on the rings...IF they are of high quality, then I can do it. Just prefer "hub centric" wheels.
Is your "et" number the wheel offset?
I.E. 19x 9.5, et 45 being 45mm of positive wheel offset
That's alot of math, do you know the stick Type-S wheel offset?
Checked TireRack, no Type-S winter wheel/tire package option yet

stock summers are 20x9 et 50. Off set changes with wheel width though so a 20x 9 et50 is not the same as a 20x10 et 50 or a 19x8.5 et 50. Its an easy way to really throw off your wheel stance.
a lot of high end wheels like vossens and bbs as people have mentioned will have more wheel width options, but for the northerners like me, no one really wants to drop 3-4 grand on wheels to drive in the snow. I love the stock summer wheel package and intend to use them for summer use but i need something for winter that makes sense, hense the 19” wheels with less width options.

Wheel stance is just a minor appearance issue. The major issue is fender rubbing. Too low an effective offset will push the wheel/tire combo further out from the wheel well, and rub against the metal fender and/or plastic bumper whenever the vehicle goes through bumps and dips on the roads, while carrying a couple more passengers.

Agree, gotta factor in the wheel overall width. You mentioned wheel scrub radius, the other factor on changing wheels is bearing load but from the mm numbers you presented I don't think that'll be a problem. Honda/Acura typically use NTN bearings for their vehicles, and they're fairly robust.
I take it there are no cheap steel 19" wheels available yet that met the bolt pattern and dimensions you're looking for?
