Guys I just got Michelin pilot super sports. Not as impressed as I thought I would be but still much better than stock. I have 2014 6 speed V6 coupe. What pressure recommendations do you recommend

Assuming you bought standard sized, stick with the TP recommenced by Honda. You'll find them on the B pillar sticker

I try to keep mine around 32psi. I checked them the other day after about 2 months, and with temps cooling they had dropped to 28psi. Keep an eye on pressures, especially this time of year.

I have Michelin Pilot Sport A/S 3 and am quite pleased with them, I use 35 or 36 lbs in all 4. Owner's manual recommends 35 psi for high speed driving which they define as over 100 mph, but I think if you drive on 75 or 80 mph freeways 35 psi would be a good idea.

Why not set the pressure to the value posted on the B pillar and in the owner's manual?

What size did you get them in? What pressures are you running?

What are you unimpressed with?

On my G, 225/50/18 front, 245/45/18 rear, pillar sticker recommends 33 psi all around. This is fine around town. When I hit the curvy backroads, I bump it up to 35. At the lower pressure, the car feels more squishy in the corners - softer, less precise handling.

I have the stock size 235/45/18. I think recommended pressure is 33 in front 32 in rear and that's what I'm running. I guess I just expected more stability in cornering at higher speeds. I also have 22mm sway bar

Also I do mostly freeway driving 75-80 mph

I would use the recommended pressures as a minimum, they seem biased toward a nice soft ride. I have noticed better handling and tracking with a few pounds more. I have tried different pressures between 32 and 42 lbs and finally settled on 35 as a good pressure for my driving style. I think I can tell more about tire pressures in my car, on the roads I drive on, than some guy in an office building in Japan that may not even own a car. Seriously I realize they do some testing and know what they are doing but they are picking one pressure for all conditions and however much weight you are hauling around. This implies that it probably isn't all that critical. I think the important thing is never drive on under inflated tires. I don't think very many people die from over inflated tires but a lot of people have been killed because of under inflated tires.

Because it's biased toward comfort and my priority is performance.

My Michelins are 235/45-18 stock size for 2014 Sport. I agree with your assessment, pressures need to be a bit higher than 32/33 to eliminate the "squishy" soft feel. As I posted above I usually use 35 or 36 lbs, going higher than that doesn't really seem to do much except stiffen the ride and increase fuel mileage.

It's difficult to find a good medium. I remember reading some reviews that states the pss's had somewhat soft sidewalls. Roads around chicago are generally in bad shape, quite bumpy. Keeping the lower pressures helps mitigate this somewhat. The bridgestone re050a's previously installed had real good feedback and response even with the lower pressure. Tread rating was only 140, and they were shot in under 20K miles. Not to mention, after about 50% wear, got extremely loud. We'll see how the pss's hold up.

At 35 psi on reasonable smooth roads, the pss will really shine. I've railed some technical corners at a good clip without any issues, sliding or squealing. This assumes warm ambient temps and warmed up tires. Even 36psi was decent on smooth roads, but too much once I got back to the metro area with all the bumps and potholes.

More stability desired = greater tire pressure. If you are running 33 now try 36-38. As tire pressure increases so will impact harshness. I guess you'll need to find the cross over point between stability and harshness with these tires for your preference. By the way, what is the max pressure stated on the sidewall?

Good comment on pressure. My Pilot Sport A/S 3 are 44 psi max.

 

[trusaleen1]

Thanks for all the good info. Looks like 35-36 seems to be what I'm looking. And FYI max pressure on the sidewall says 51.

Tire pressure is a controversial topic. The Honda recommended spec is always the safest choice but you can experiment by adding a few PSI until you find the sweet spot.

My Accord calls for 30 but the ride is too splashy for me. I've been running 32 front and 33 rear (I carry a full-sized spare) since I got new tires put on. 40K miles later, they're wearing great with no cupping. The few extra PSI also gives a buffer during temperature fluctuations.

Keep your car aligned, tires regularly rotated & balanced and you'll be golden.

Is there a way to see the TPMS reported numbers somehow or do I need a can-bus/obdII reader?

 

[GPz1100]

Honda uses an indirect [dumb] tpms system in this car. It bases loss of pressure on a significant change in wheel speed. When a tire deflates its diameter changes. You would need a third party tpms system to get actual numbers. Some companies sell valve cap covers with transmitters. Not a good idea imo. It relies on keeping the valve core consistently depressed.

Check your tires weekly or every other week and you'll be fine.

The Generation 9 Accord does not use individual TPMS sensors in each wheel, I'm not sure about previous generations. The Gen 9 cars use the wheel speed sensors and detects a low tire by looking for a wheel that is turning at a different speed than the others (indirect TPMS). So the actual tire pressure in psi is not monitored.

The indirect TPMS has a couple of advantages, no batteries to go dead, no RF sensors to be screwed up by the tire changer, and you don't need to buy extra sensors for your snow tire wheels.

I have had indirect TPMS on two different cars, my present Accord and my 3 Series BMW. This system seems to work fine and I have had no problems with it on either vehicle.

Thanks for the info. Do you know how sensitive it is? Like if one tire is at 30 psi vs 32? I assume Honda calculated wheel speed at some threshold (30psi) to trigger TPMS alert. If you use a different size tire or rim is there a way to re-calibrate it?
