tsx_07

So far, I never filled air in my 1.5 months old TSX but yesterday i noticed front tires looking somewhat deflated so I decided to fill air but to my surprise, tire pressure was already 32/30 psi in front and back as recommended.

Is it normal? I am pretty sure the front tires were not looking this deflated before.

its probably flatspotting, it happens when you left your car on a spot for a long period of time.

So that means the wheel won't turn as a circle, therefore more gas is wasted? =[

For about 5 seconds until the tire warms up a bit.

To the original poster -- I prefer to run my tires higher than the recommended. I use around 36F/35R and it feels great. Many others use a higher-than-recommended pressure as well. Run a search for the "-10% rule" as that's what I've based my pressures off of (with a bit of downward adjustment to get a more comfortable ride).

^ Thanks. I'd try that.

If I remember correctly, the TSX's came with around 36psi in the tires right off the lot.

tsx_07

all four of 'em?

I believe the recommended pressures are 32F/30R but I've been driving with 36F/34R. I even had it up to 38F/36R for my last road trip to Nor Cal to get better mileage.

Might have been 36/38. I know it was higher than the tire was rated for. I think they do this for shipping purposes.

tsx_07

Really???

Why not drive at high pressures everyday then?

jlukja

At 38/36 it feels just a little too hard, particularly around town where I enter/exit driveways, drive over poorly maintained roads, and have a section of freeway nearby that seems bumpier than usual (605 southbound between South Street and Carson).

I see..but out of curiousity, did it actually give your better mileage? I have been getting about 22-23 mpg (75% city, 25 % highway) but i have just 2500 miles on it as of now. i understand after 4-5k, it probably should shoot upto 27-28 in similar driving conditions.

jlukja

Your mileage should improve as you get closer to 8K-10K miles. Mine did. And, yes I did get better mileage with higher tire pressure. Coming back from Nor Cal I averaged just under 35mpg for the tank, got something like 514 miles before refilling.

tsx_07

514 miles? thatz awesome !!

So I take it you don't have an 07 TSX?

his screen name lies!

i noticed this as well on mine, i have around 1100 miles on it. the fronts are noticebly 'deflated' more than the rears look. i attributed this to the front of the car being heavier than the rear.

tsx_07

Nope. I registered before i bot the car with an intent of buying an 07 but then getting an '06 car for about 3K less appealed to me and i went on to buy an 06. Now I am wondering the benefits of TPMS.

alucardx

benefits: being a lazy piece of a crap and not checking the tire pressure the old fashioned way

dom

I'm all for not being a lazy peice of crap and doing it the old fashioned way but the TPMS system in the 07 TSX doesn't fall into that category. I bet 2% of people check their tire pressure regulary. This ensures safety and better MPG as people will now start paying alot more attenton to their tires. Its about time.

I run 36/34 usually. Works great, good balance between comfort, handling, and mileage. Sometimes 34/32 in winter when everything seems to be stiffer, gives a little more comfy ride. Be mindful of the 10-deg rule (+/- 10F = +/- 1psi) -- the colder it is out, the lower the pressure will be in your tires aotbe.

tsx_07

To me, TPMS is more like a nice to have utility like auto door lock. Not that you can't check the pressure regularly like locking the doors yourself, but it would be a nice to have feature.

Well...front tire looks flat because your engine is in the front...therefore heavier...
