Correct Tire Pressure for 18'' A-Spec Rims

Correct Tire Pressure for 18'' A-Spec Rims
Does anyone know what the correct tire pressure is for the 18'' A-Spec rims?
I know that for the standard stock 06 rims on a manual, the front two tires are 39 PSI and the back two are 36 PSI.
I went to the Acura dealership and they said that for 18'' A-Spec rims, the correct tire pressure is 36 PSI all the way around.
Does that sound right?

Okay so the correct tire pressure is 39's in the front and 36's in the rear. Correct?
It's weird that some people have 35's in the front and 32's in the rear listed on a sticker in their door. Why would Acura recommend different pressures for the same kind of wheels?
Thanks for all the help everyone!

It's weird because the TL owner's manual says that for stock 17's, the correct tire pressure is 37's in the front and 34's in the rear for a 6 speed manual. The pressures are different for an Auto.
Gosh, what's with all these different tire pressure readings!

I know for high speed driving, i.e. road trips, you'd want to have higher PSI. It just depends on the road conditions and tire brand/type/speed rating. MPG is also affected by PSI levels. I recommend higher PSI in the front than the rear on the 6MT. I've been playing with PSI levels after getting my 19's I'll have to see what works best.
Remember some tire shops / lube places don't know better, they put 35s all around.

I just experimented by putting 39's in the front and 36's in the rear and the ride is perfect.
Awesome!

Dealer and private mechanic recommends...
I notice when I bought my 06 TL, the pressure reading was 41 all around. I thought that was excessive since the door jamb recommended much lower psi. The salesman told me they must know what they're doing, the mechanics put 41 psi all around.
One day I got a nail out of my tire at a local garage. The mechanic said he recommends reading the max. psi off the sidewall and put about three pounds less than what is stated on the sidewalls. Sure enough, it was 41 psi.
Two different opinions both say 41. I get better gas mileage, a slightly stiffer ride, but you get used to it. The mechanic said that tires last longer at the higher psi.

Higher than recommended pressures will reduce ride "quality" (or increase ride stiffness) and stiffen the tire sidewalls, which is good for tire wear and vehicle control, but reduces tire tolerance for impacts by decreasing tire flex.

So wait....is it 35 front/32 rear or is it 39 front/36 rear?
Does it matter which pressure combo from the two I choose? I'm assuming the ride will feel a bit different for both.

Lower pressure may result in softer ride, but lower gas mileage and maybe slightly more tire wear. Higher pressure will result in minor MPG improvement (no more than 0.5 MPG) while stiffer sidewalls will give better transient response and less tire rollover, but watch for rear-end "twitchiness" at speeds exceeding the legal freeway speed limit.
Don't go over 40 lbs. cold for everyday street driving.

Crack in wheel. In post-Katrina New Orleans, there is a lot of demolition going on. I happen to have to drive towards the landfills where inevitably nails fall off of the numerous trucks making runs to landfills. One day, my fourth flat I believe, my mechanic couldn't find a nail. He looked around and found the culprit. The aluminum alloy wheel was cracked on the inside of the wheel. I would have probably never found it. I called Acura. At first they were reluctant to replace it, stating it was caused by a road hazard. When I started to complain, they said alright bring it in. They replaced it right away with a brand new wheel, no questions asked. I wonder if keeping my tires inflated at 40 psi contributed to the crack? The higher pressure would give the tire less cushion if I hit a pothole. I just don't know. The problem was discovered after I drove from New Orleans to D.C. and back. So there was a lot of high-speed, high heat-generating driving. Could that have contributed to the crack? I wonder. Anyway, I'm going to change my 40 psi all around to the 39/36 pressure to see how that works. I hope the mileage doesn't drop significantly. I average 32 on the highway. It's a 2006 5M w/ navi.

You might see an improvement in handling from 39/36 due to reduction in understeer and rear-end sensitivity, compared with 40/40, to make up for any loss in MPG.
I think 39/36 is recommended for the 18" wheels like the A-Specs; recommended psi is a little lower for the stock 17" wheels with the 6M. I like to run 36/33 with my 5A, which is a little above recommended.

i have no clue why, but acura changed their specs for 18" tire pressures :
04-05 18" tire pressure on sticker is : 39F 36R
06 18" tire pressure sticker says : 35F 32R
but were talking about the exact same specs wheels (difference of TPMS added but that's all)

There may be a difference after 05 because the ASpec rims went from an 8.5" to an 8". Not sure if it was after 04 or after 05 but that may be the reason for the difference in tire pressure standards.
