Hi guys,

I have a question about the tire pressure on my new 2016 RX 350. The right front tire pressure is always lower than the others. I wasn't aware of this until recently that I found out that tire pressure went to 28 while others are 35. I drove to the dealer and they inflate it to 37. The second day, the right front tire pressure when to 33 while others are still 35. When I drive it on highways, since it is still summer, the tire pressure all go up but the right front tire pressure is always lower than the others.
I am not that an experts on tire pressure. My previous car was 10 years on so there was no tire pressure monitor and I never check this regularly. So do you guys see something similar or do you think this is strange?

Many thanks in advance!

Probably small puncture. Keep monitoring and if it will keep going down you'll have to take it to tire shop.

i would keep an eye on it. Better yet get a inexpensive electric tire pump at Lowes or Home Depot and a good tire guage and measure and fill them all to close to the same pressure. $30 all in. It is not rare to have one or more tires a pound high or low. Your tires and the air in them was warm when the one was adjusted which is why I like to do mine when they are all cold.
Either way it should not go down any more until any cold weather starts. If it does it is not seated right or has a slow leak.
My thoughts on it anyway,

Betting on a small leak.

I had a similar problem on my Cadillac SRX and the tire was re-sealed by the dealership and the problem was solved. Evidently there was a slow leak from the seal of the tire to the rim.

If you can, carefully look all around the tire's tread for a small screw or nail. If you do see one, do not remove it. Have it repaired by your local tire shop, typically for about $20.

You could try to detect the leak by spraying soap solution on the tire and around the rim. Air bubbles in water is probably better method, but requires removing the tire and a big tub. If it turns out to be around the rim, then it's likely a mounting problem. Is there any road hazard warranty on the tires?

Thanks guys for the advice. I have about a gauge and will look for the leak.

Get a spray bottle and add some dish soap in it. Spray your tire in various areas, especially on the valve stem. If you see any bubbles coming out, there's your leak....

Submerging the tire in water is something my tire guy did when I had an inexplicable slow leak. The tiny bubbles broke the surface and isolated the problem to weights attached to the rim. Just remember the dealer doesn't warranty the tires so you may need to go to the brand''s authorized dealer for repairs. It's explained in the brochure you should have received with the owners manuals. Good luck.

What is optimal tire pressure for the 2016 RX 350 anyway?

There's a sticker in the driver's side door jamb, below the latch, that tells the recommended pressure for your car and tire. For my 2016 RX 350 with Bridgestone Ecopia H/L 422 Plus tires, it's 33 psi.
