245/40/18 fronts
275/40/18 rears

Can anyone tell me what I should inflate to?
Thanks!

 

I just bot Michelin Pilots, same sizes. Discount Tire put in 40psi. (Wheels are 9.5")

Corners like a dream and I can still burn'em at will.

I'm gonna measure wear and adjust the psi if nec.

Love the tires!!

 

I have new Michelin Pilot Sport A/S. The front tires are 35psi; the rears are 32 psi. The higher pressure in the front tends to alleviate the feathering wear that can occur on the interior sides of the tires. Both Nissan and my dealer technician (for whom I have high regard) recommended those figures. My alignment is right on the mark.

 

Re my previous post, I should have mentioned I have 17" wheels.

 

Thanks guys, yep..Discount Tire put 40psi all around as well for me too.

 

I have same size setup as above. I was running 40 all around, but I was told that was a little high for street use....now I'm running 36F & 35R.

I've been on this psi setup for about 4 days now...... I'd be interested to see what psi everyone else uses.

Subscribing to thread...

 

Street: 34 psi front and rear with 245/45-18 all around. It seems to work pretty well but I might try taking out a little air to soften up the ride a bit.

Track: I try and aim for about 41 psi front and 40 psi rear with 275/40-17 all around. I need extra air in the front to keep the tire from rolling onto its sidewall, not a concern on the street.

 

I forgot to mention, street pressures are taken cold, track pressures are taken while hot.

 

I run stock tires at 45 in the front and 39 in the rear for the track. Helps with understear. On the street I run 38 all around.
