Hey guys,

I recently purchased a Veloster Turbo 2013, it came with aftermarket rims/tires - Michelin Pilot Sport A/S 3+ (225/40R18) summer tires. I'm not very car savvy, and need help with determining how much air pressure I should use. I'm wondering how much PSI I should aim for?

Thanks in advance!

Set at 30 psi. This will have good comfort, grip, and no tpms light as long as the tpms sensors are in the wheels and operating.

Fyi, I think those are all-seasons not summer tires. Pilot® Sport A/S 3+
Not sure if that makes any difference to you or not.

I typically aim for around 32 psi unless I have a specific event I plan on participating in (read, never anymore. lol)
If I am going on a road trip with a lot of miles cruising on the highway I will air up to 36-38 psi.

Ok, not to take from the original thread but this is still on the same subject matter so here goes. I'm always one to learn and maybe learn something new.

@trdtoy had suggested to use 30 psi for the tires and am wondering why and how you figured that particular air pressure.

I'm runningYokohama S1 summer tire with 205/50R15 size and use 34 psi up front and 36psi for the rears.
Handling is great with minimal edge wear on the factory alignment so would you have any suggestions here?

Thanks.

If I were to give a specific pressure recommendation it would be different each corner and the tpms light will come on if those are in the wheels and working. I just suggested 30 psi as that is high enough that it should not go low enough in the cold to trigger the tpms light but stiff enough to run good all around conditions.

Had my tires rotated by the dealer a couple weeks ago and I just checked the tire pressure. All 4 of my tires were at 42psi. The sticker in my driver's side door panel has 33psi as the recommended tire pressure so that is what I set them to. Max pressure listed on the tires say 50psi. Why would the dealer set my tire pressure so hi at 42?

Read in another post that the higher tire pressure better protects the rims...is that why?

Every tire is a little different. Overinflated could accelerate wear on the middle. Under inflated could accelerate wear on the edges. All tires are different but the door sticker is a good starting point.

The easiest thing to get the right spot is to mark the edges. You want the mark just above the edge of the tread when scrubbed during normal driving.

do this for the front, one tire would be enough and set them all the the pressure where the scrub is optimal. This will give you the best longevity although there may be a tiny less comfort.... or not.
