Hey all, so I have my 2018 sport 2.0 T. Right now stock OEM all season tires. I know that our tires are rated for 33 psi all the way around. However, for performance driving, a very old family mechanic told me many many years ago that putting a few more psi of pressure in each tire is good... I’ve been the psi of pressure by 38 all the way around, would help. Is that still true? I’ve been putting about 38 psi pressure on my tires. Thanks for any help I really appreciate!

I run/set mine to 35 PSI... my mechanic had set them to that on delivery and each time it was serviced so I check/keep it at that every month when I check tire pressure. Don't know why he did that and never asked... trust him enough that I figured he had good reason to do it. 🙂

If your running the OE Michelin Primacy, then the max psi is 50 not 33. Thirty three psi is what Honda recommends for ride comfort ect. If it were Europe, same tire would have higher psi "recommendation". So you technically are not overinflating your tire, based on the max psi. I always check the max psi of my tire and look at the weight of the vehicle, tire size and type, and driverain layout to determine my psi. Your mechanic is correct, on top of that you will get better fuel economy. The only time you want lower pressure is for drag racing. Imo 38-40psi is good for that tire. You will get better tire life, as well. The recommended 33psi is a little low for my liking considering the options. But as I mentioned earlier, they feel Americans want a softer ride. You can try 40psi if you like, but it will be a stiffer ride. Anything beyond 40psi isnt necessary imo, the car only weighs 3400. If it had another 500lbs or so on it, then yes. Im at 6/32 on my original tires right now so new shoes coming at end of next month probably. Going to switch to Conti DWS06 all seasons, and a wider/lighter wheel.

yeah dude as you can tell i do love things on the stiffer side, which is perfect. At least my mechanic knew what he was talking about. That’s for sure.. thanks again for the suggestion which backed up my idea completely! :) (y)

I will say that for my next “good” set of tires, a lot of things will be different regarding them of course.whenever my car is ready for new tires, I’ll either put on ultra high performance all season tires, or just summer tires onto it. Just not sure yet. Of course though, I’ve got time to figure that part out though. 🤪😬🏁

Can't go wrong with Michelin PS4. It a max performance summer tire that handle amazingly in the wet. If you don't need winter handling, they are def where it's at! Cheers

Based on my needs and preferences I just changed to the Michelin CrossClimate2. It's too soon to give any feedback on performance, mileage, etc. You might want to check them out: https://www.tirerack.com/tires/tire...VR9CC2XL&vehicleSearch=false&fromCompare1=yes

I always use the 90% max rule. I've been doing this for decades with good results. I get a lot of push back about this rule, yet I've always gotten good traction, mileage, wear, and comfort from my tires.

My tires are rated at 50 PSI max. Therefore, I inflate mine at 45 PSI (50 * 0.9 = 45). So far so good. Most people feel this is way too much for them. The ride may be stiffer, but I don't notice any unusual harshness or discomfort with that PSI.

Regardless of whether you inflate as high as I do or not, 33 PSI on a 50 max tire is only a 66% inflation rate, and just way too low IMO.

The 36 PSI is recommended for "High Speed Driving" ("If you drive at sustained high speeds (over 99 mph or 160 km/h), adjust the cold tire pressures as shown below to avoid excessive heat build up and sudden tire failure.")

Hi everyone..
Max press on my tires is 50 psi. I have a 2020
Accord touring hybrid.
I routinely drive
8-12k a month (not a typo) as a courier who obviously drives mega highway miles. I get excellent balance,
wear and a very comfortable ride
with 42 psi and very good mileage
on all seasons in sport mode exclusively. I do not use the other modes. Upwards of 42 mpg all day long on city or highway
roads. I've had my car exactly one year and it has 78,000 plus miles on it. Hope this helps somebody

Have you tried them at 40psi?

Yes I have.
I guess it depends on type of tire, tire pressure and driving habits.
I just got back from a 705 mile trip to Owensboro, KY from Chicago and got 42.2 mpg. 14 hours driving.
And I drive normally. 72
in a 55. 78 in a 70.
Hope this helped and good luck.
