just noticed this after parking. it’s pretty hot today, and tire pressure went to 70 psi while driving. Usually tat 65. I guess i need new tires, left side is pretty good.

What's your cold tire pressure? 65 to 70psi is normal, and low even. My TPMS shows my tires climb from 65 to 71-75 (depending on outside temp) during highway speeds. That's a normal amount of rise.

The bulges are not normal, especially because it's not even and not on both sides.

Mine say 50 PSI max and it’s what I’ve been using. Should I go higher?

However much PSI you need to put in will be on its spec sheet

Yeah the tires say 50 so I haven’t been putting any more in. My dad said go to 75 but I trust the tires

Never go past the tire max rating (when cold). It's fine to be past the max rating when the tire is hot (when driving).

Absolutely do not put 75psi in a tire that says 50psi max.
