My 2019 GT Turbo is running on Kumho Crugen HP71 tires that the previous owner installed. The description & reviews on Tire Rack say "quiet & luxurious ride" and "minor tread growl". Do you think changing tires will give quieter ride?

 

For what ever its worth you already have a tire with a tread design for a quiet ride. IMHO unless you were to compare new to new and using a db meter I doubt your ear could hear any difference to a degree warranting a new set of tires from what you have.
ALL tires start to get harder as they are used and with age. This is a fact backed by comparing store new tires with newly manufactured tires and confirming the production date on the tires. All those tests were conducted using a durometer.

I choose to change my tires out at less than 40k miles because my durometer test shows them getting harder than new comparing my base line numbers. The funny thing is I went with a performance tire replacement which is not even close to the quiet ride new of the tires replaced and even my wife noticed that the normal daily drive seemed quieter. Both those are subjective and not empirical because to be human is to be fallible. However, when I test using proper testing equipment it is hard to debate or argue the results!

 

Thanks Calisto. Not sure I want to go that far. Also have noticed that this 2019 GT turbo has a louder exhaust sound than my 2020 GT non-turbo. Normal? Different muffler to sound sportier?

 

Sorry I never compared so I am not sure unless I went to MAZDA parts and see if there are specifically different muffler and resonator part numbers and then do a reverse cross parts check to see if they are the same for N/A and Turbo model? So basically, I don't have an answer. LOL

On a technical side the mufflers, CAT and resonators all really should be the same comparing this platform and between N/A and Turbocharged engines because the only time a higher CFM would be possibly beneficial (and that depends on the ECU calibration) needed in the exhaust would be towards the upper RPM range of each of the engines at abut 6K-65K range. So, IMHO if there is a nose difference it is purely for the effect TURBOCHARGED so "RACE CAR" ?

 

How old are the tires ? How many miles on them ? Due to the chip seal road surfaces and high heat here in Phoenix, tires get hard and noisy after only 2 or 3 years and 20000 miles here in the valley . They may still have plenty of tread and look great ,but they are loud and don't ride like they did when new. You may want to check the sidewall for the date they were built . Age can also be a factor.

 

Best car for fit and finish in its price class. Mediocre gas mileage. However, I downgraded it on noise, electronics, and software. In those categories about one generation behind with poor integration. Mine is a 2020. Maybe the 2023's are better, as are its competitors I suspect.

 

That statement is all opinion and/or driver habit based.
I get excellent gas mileage normally around 30-32mpg for all my driving which is better than my previous Honda CR-V or Hyundai Santa Fe.
My 2020 is quiet now since I replaced the very noisy OEM tires.
I don't purchase a vehicle for electronics or software so that has zero impact on me.

 

My 2023 also gets 30 to 32mpg on average, and i have been told I have a heavy foot. At almost 4000 lbs ,the CX5 fuel mileage is about as good as can be expected .The way the CX5 handles and rides is also best in class . As to the electronics , they work fine once you learn how to use them. Mazda got the important things right. The choice of tires that Mazda made is more than likely a cost saving issue, and the vehicle could be made quieter ,smoother, and handle better with an upgrade in tires . In the end the CX5 is still the absolute best choice in its class at the price . All anyone who test drives a Toyota Rave 4, Honda CRV, Nissan. VW , Hyundai, or Kia and than drives the Mazda CX5 knows this already .

 

No, this isn't ALL opinion lol. From Mazda's own website regarding the 2020 Mazda Cx5 AWD:

"Skyactiv®-G 2.5L four-cylinder with i-Activ AWD®: 24 mpg city and 30 mpg highway"

The "opinion" about the gas mileage, noise and infotainment bundle were, and are as a matter of fact, also shared by Consumer's Report. The poor electronics and software were reported by many reviewers also. I knew all this before I bought the car, so I'm not claiming to have been mislead by Mazda. I, and anyone that hasn't actually owned the car, really can't appreciate how much these problems with the car's modern conveniences influence the overall owner satisfaction. So, that's why I think it is important to put real life experiences, like yours and mine, on a thread started by a Mazda advertisement.

 

As far as the fuel mileage, mine has been better than advertised, and I have a problem with obeying posted speed limits . My 2023 CX5 is far quieter than my friends 2023 Rav 4 ,or my nephews 2022 Nissan Rogue. If your not happy with your CX5, you can always sell it and purchase something you think is better and like better . What possessed you to purchase the CX5 knowing of it's so called short comings ? Was it the great handling and ride ? The better than the competition fit and finish inside and out ? The price /value for money spent ? Did you buy it new ? Did you buy it used and get a great crazy low price . Something made you buy the CX5 ,what was it ?
