How is your ride quality with 20" wheels?

[paris1]

I've read quite a few comments in the automotive press about the poor ride quality of the CX-50 with 20" rims. Unfortunately, that would be the only wheel associated with the trim levels I would consider. So I'm wondering how folks who have that setup feel about the comfort level of the car?

The ride quality on the CX-5 sig. loaner i drove (19's) was awful. slow to respond, cumbersome, heavy, so much unsprung mass, took otherwise good crossover suspension tuning and made it feel virtually useless.

My wife has a '23 CX-5 with 19s and we've recently had occasion to rent the same car with 17s and there is a noticeable difference in ride quality. That's why I'm wondering if the same is true with the 20" CX-50 or if Mazda has tuned the suspension any better with the newer design. Also, my 2018 Mazda 3 has 18s and the ride can be a little rough, but you expect that on a smaller car with shorter wheelbase and besides, it handles a whole lot better that its SUV counterpart!

Massive, heavy OEM wheels and giant tires can't exactly be tuned for. That unsprung weight will constantly be working against the suspension. Even the 18's on your 3 are going to be heavy.

The 17's on my 6 with the same aspect ratio as a cx5 sig (55) felt much better.

I'm changing to some flow formed wheels in spring that are 10lb lighter per wheel than stock.. that will make a huge difference.

If you're serious about the cx-50, I would put lighter downsized aftermarket wheels on it.

Having driven a CX-50 with the 20's and another with the 17's, and CX-5's of both generations with the 19's and 17's, AND having swapped my 2nd Gen CX-5 19's for 20's with a completely different (and better) tire, I can tell you with 100% certainty that what you are describing is the fault of the 225/55/19 Toyo A36 on the 19x7" wheels.

I wasn't happy with the feeling that the rear of the car and the front seemed to respond at different rates, with the back lagging behind the front, when shifting direction at highway speeds. The main problem is that it's not a sporty tire and responds slowly.

My lowering springs with higher rates probably helped with this as well, so consider that into the equation. The car is much tighter now and responds instantly, both ends in sync.

So combine soft springs and soft sidewalls and that's what you will get. Get in a CX-50 with the 20's and it feels completely different. That car is more direct, with very little body roll, yet a bit harder ride quality than the CX-5, partly due to losing the IRS and partly due to the wheels. It feels like the sway bars may be stiffer, too, because I don't know how else to account for the lack of body roll. This provided a more enjoyable turning experience, in my opinion.

Regardless of what tires, the massive circumference and diameter of 225/55R19 is insane.

Even with good tires and lightweight wheels, im completely lost with this trend involving giant wheels and tires accounting for obscene diameters. Literally serves no purpose whatsoever and yet another reason why I would stay away from anything higher than a sedan, until the day comes that I need to.
