Lowered PSI for Comfort (6 Viewers)

[clindsay123]

Hi everyone,

I recently got a new set of wheels tires as I've been on a quest to find the sweet spot for daily driving in Los Angeles / durability in the Sierras and deserts of the southwest where rocks are plentiful.

I landed on 285 70 17 C rated Ko2s which came in at only 50 lbs per tire! My previous set were E rated Ko2s and I hated the jarring ride. I was disappointed to find that the C rated tires weren't much of an improvement in NVH, even at 35 PSI.

That said, today I lowered the PSI to 33 and they feel MUCH better. Seemed to have passed the chalk test as well.
I did notice there is a very small bulge at the bottom of tire (pictured below) and am curious if this is an issue at all. It's not too noticeable in person unless you look for it. America's Tire said it's totally fine but I don't trust them as they probably want to avoid me exchanging tires.

Thanks!

Looks normal to me.

If you were going by Toyota recommendations for load/pressure, you would run 36psi front, 39 psi in the rear. You certainly can run a few psi less day to day but I would run 36/39 or more when loaded up.

Thank you Coin, I know we are both suffering victims of the E rated tyranny

ya I’ll definitely up it to 35+ when loaded

Aren't even close to the stock tires so those numbers mean nothing.
Even switching brands can sometimes change what you should be running.

@x8o8drifter I converted the numbers, they do mean something.

50 lbs per tire is heavy. Been there done that. The 41 lbers ride much better and ive not had a flat yet.

Corection: I meant IF you don't do anything to correct them.
Like 99.999% of people will do.
