36psi Vs. 42psi

[ecomodded]

I notice with my car at 50 psi in the rain while 'speeding' the front tires start to plow a bit on hard corners / extreme winding roads, that traction loss starts at 50mph while driving in a posted 30mph zone. The rear has not started to loose traction in the rain on me yet though .. and that's in years of driving it at 50 psi

On a random note, I checked the pressure on my new front tires (yea yea I know I should change the back too), and the shop filled them up to 39 psi! I think they must've checked my rear tires and discovered my higher than normal inflation pressure, and matched the front.

Does anyone maintain the pressure difference between the front and rear tires, e.g. placard says 30psi front, 34 psi rear when increasing pressure? Does it make a difference?

I do, my car is rear heavy and has bigger rear tires so I maintain higher pressure in the rear. I think it's a good idea since you are allowing relatively more compliance where it's lighter, and you're changing the handling less as you're not effectively stiffening up one end of the car.

Hi guys! Last week I installed a partial belly pan in the 2002! And on a recent trip we averaged about 25.75 MPG going 75 mph (no I was not driving)
And the average FE is up to 22.71

My front tires are rated at 45 max, and I run them at 55 psi. It feels really responsive with the rack & pinion steering. The rear tires I keep at 50 psi, they're different tires and rated a little lower for max pressure, can't remember exactly what they're rated for.
The car gets great roll at these psi's, but if it's wet outside I pretty much just creep it around since there's a better chance at hydroplaning at those pressures
I haven't noticed any funky tread wear from the higher psi, but I definitely feel every bump in the road!

High psi doesn't cause hydroplaning. It's the opposite, actually. But perhaps what you feel is tramlining or twitchiness caused by the high pressure.

Yeah, what he said!

When I bumped the Van up to somewhere around 65 PSI (The air pump read it as 48 and I didn't double-check it with a gauge then) the rolling distance was increased. We also felt many more bumps in it and rode around like that for a week before one of the tires went flat on us and we found what happened.

Gee, What increase does Boxy get going from 35/39 to 40/44 and 44/48? Does 51/55 get even higher?

I can confirm that 36 is spec for my 2004 Odyssey and for my sister's 05. I expect the 02 would be the same, being the same generation as mine, and the 08 being the same as my sister's.
