[COS-16SXL]

Have spent many a night planning how to swap my wheels for my neighbor's Cadenza wheels without their noticing.
Have always liked that look - BUT - the BIG question = How many $$$ - And -- what Size are these?

 

[Turbonut]

Got to say that I like the look, but not certain as to the year of the wheels, but I'm going to guess '14-'16 19"x8" 41mm and an A code wheel @ $100 each. The wheel will move out @ 22mm, 7/8" and the OEM tire size on the Cadenza 245/40-19 @ the same diameter as the 215/55-17 on the EX.
Don't know wheter I could stand the tire size/stiffness on our Turbo as the car rides like a truck, actually most trucks offer a better ride, maybe like a covered wagon would be a better example.

Personally I'd prefer to mount a 235/40-19 tire if going 19s on the Optima since its circumference (82.9") is much closer to that of the 215/55-17 (and OEM Optima 18" 235/45-18--both 82.7") than a 245/40-19 would be (83.9"). Sure the 245/40-19 may give you a wee bit more road "cushion" compared to the 235/40-19 due to the slightly-larger sidewall, but at the expense of a slightly more inaccurate speedometer reading.

I use 225/55-17 and the diameter looks great, as said before, same size as the 245/40-19 and actually the speedo is dead on.

They are actually 225/40/19 it rides good and they look good on the wheel slight stretch I’ll take some closer pictures

 

[Turbonut]

A 225/40-19 is a size that can be used on an 8" rim and not be considered a stretch.

Yeah you right

So If I'm -- 235 x 45x R18 -- on the '16 SXL, = OK ??/ NO? & best educated Guess on the Ride and Speedometer impacts If OK?

IF Not a typo, $100 ea would be purchased Where? Would love to get them ..........

Just wanted to add that tire sizes from the factory differ:
205/60-16 25.7"
225/45-18 26.0"
215/55-17 26.3"
235/45-18 26.3
245/40-19 26.7

As stated before I have 225/55-17 26.7" and speedo right on.

Thanks, T...... The '16's aren't the 20-Spoke look but I see some 15's with 'em. Good quality appears to be 175-200 Ea and some damage can be $125.
Will pursue with some local help but don't expect an easy acquisition.

Put in 2014 and there's quite of few A code wheels $100/$105

I use 225/55-17 and the diameter looks great, as said before, same size as the 245/40-19 and actually the speedo is dead on.

Not to beat a dead horse, but it would be expected that the speedo would be dead on since the overall circumference of each of those two tires are within a tenth of an inch of each other (84" for the 225/55-17, 83.9" for the 245/40-19); however, I believe the 225/55-17 isn't the OEM 17" size so its circumference is 1.3" more than OEM 215-55/17--meaning, on paper the speedo on your car should be off by a smidgeon, but perhaps in real life the difference may not be visually noticeable on your speedo gauge--that, or else you had the wheel sensor adjusted to compensate for the use of the slightly-larger 17" tire size you used (vs. OEM 17" tire size).

 

[Turbonut]

Checked on a GPS and dead on. Don't forget, most speedo's from the factory are under 60, not dead on. Also, at least with the Optima, although the tire sizes are a different diameter, however small, the suspension and trans components are the same for the EX turbo with 215/55-17 and the SX with 225/45-18, so even if one is correct which I have found not to be the case, the other is definitely going to be incorrect. Now add in the LX 2.4 which is the same as the EX 2.4, but once again different diameters.

Similar to our Acura original 235/45-17 replaced with 245/45-17 dead on.

Next time you're out check the speedo with the GPS and see what it reads.

Write more later, out to dinner with daughter.

 

[Turbonut]

Checked when out this evening, so just wanted to add 225/55-17 12,000 miles at 60 mph with the GPS, the needle is on the left side of the 60 mph hash mark.

 

[tonester]

Could be manufacturing tolerances between brands even if comparing like size to like size but even you'd have to agree that ON PAPER there is no way that a 235/45-17 and a 245/45-17 tire can give the same exact reading. Also theoretically the speedometer reading should change (even if an insignificant change) as the tires slowly wear down since a tire with less tread will have a smaller overall circumferance compared to that of a brand-new tire but that's a different discussion for another time.

Do you happen to recall the speedo needle location at the 60 mph mark when you ran the 215/55-17 tires? Just curious since if we were to assume that with the 215 tire the needle was right at the 60 mph hash mark, then it would make sense that with the 225 tire the needle would be a wee bit left of the 60 mph hash mark since the 225 is a slightly-larger circumference tire (fewer tire rotations to cover a fixed distance, thus the speedo would read lower).

Yes, I'd like to see that KIA Wheels Store, I have a few items I'd like to have.
