2024 CX-5 GS Ride Quality and Noise Levels

[SimpleCanuck]

I emailed Tire Rack,

They told me the Pirelli runs at higher load capacity 104 or 1984 IBS per tire vs 1764 on 100 OEM.

So I would need to run it down to 29 or 30 psi to match load capacity of OEM. And likely smoother ride. Is this legit and safe?

I don't want to hydroplane or have tread wear etc. ok with slight mpg hit.

It will definitely decrease your fuel economy, as you had already discovered I believe.

I'm curious if this method is legit. I mean 32 psi would be ok. But I'd like extra rubber to isolate me. I had a Lexus dealer install and balance tires and they gave me a 2025 RX350 turbo with 19s. It was very smooth and quiet. But I'm shocked that Lexus too has become sporty... No wood or leather, piano black plastic and pleather.

I hit certain roads and it's still very jarring, and bumpy. Not as bad as a CX-5 but wow I'm not isolated from road imperfections. Hit 70 to 90km per hour and surprisingly lots of road and wind noise.

Granted it's the base model but this is 68k CAD after tax! And high theft rate here in Edmonton Alberta.

I don't think Lexus is cushy soft especially considering it's a luxury car. It used Michelin Primacy tires.

As mentioned above, the CX-5 is tuned a bit stiffer for handling. It's what helps to make you feel like your are "driving" instead of operating an appliance. Regarding the Pirelli's, experiment a little with different tire pressures. Try them at 36 psi ( cold, before driven) and go from there. It's been my experience that tire stores set the pressure on new tires to what is on the manufacturer label on the door jamb. That may be fine and specified for the tires the car comes with, but replacement tires vary in load rating and stiffness.
My 2014 came with the Yokohama 17" (G93?) and those tires were so stiff (light truck tires I think) that they came off at 3,000 miles.

Just as a follow up and reminder. Tires pressures need adjusting with seasonal changes. Cold weather drops the pressure and warm weather increases it. Daily temperature changes make a difference. The rule of thumb is 1 psi change (up or down) per 9*F change. The tires at 35 psi on a cool 60* F summer morning gain a few pounds just sitting all day when the temps hit 90*. The sun shining on the tires raises pressure. I've seen as much as 2 psi difference from sunny side to shady side. High speed (freeway) driving as well as driving on hot asphalt raises the pressure too.
So, ya gotta "roll with it". Sometimes the tires ride superb and other times rough especially on rough roads.
I see Michelin mentioned. In all seriousness, next time maybe try a set of them. Maybe they'll give you a more satisfactory ride and still decent handling. They have a loyal following for a reason. Looking back, I've wasted enough money on tires that didn't work out for various reasons that I would have been ahead buying them. Could have done worse.
Subjects like tires, along with motor oils/filters and brake pads are going to get differing responses. Good and bad alike depending on respondents experiences. And I agree when after following recommendations it's disheartening if our experience doesn't match our expectations. But there are members here who like the Pirelli's, myself included.

No. Sir.

No. Sir.

No problem 34 it is

I haven't been following this thread but just went back to the first page of this very lengthy thread and read what the OP posted. Summary of my thoughts.
1) this is a mess
2) the YOKO's (G91) same as I had..... suck. They ride harsh. That's why they got changed at 3k miles. Subaru owners with them complained of poor snow traction also. Don't know , never ran mine in snow. Maybe you should have tried Michelin's.
3) the suspension is what it is. Why go through a bunch of expensive contortions to change it.
4) load calculators and low tire pressures. Looks like a confusing rabbit hole and you do NOT want to run low pressures.
5) Do you have leather seats? While waiting during oil changes at the dealer (around 2018, 2019) I'd check out the showroom models. Could not believe how hard the leather seats were. Got uncomfortable real fast. I was used to my broken -in cloth seats. Tires, suspension ,seats. It all adds together. But I'm sure you gathered this by now. Good luck.
