Khumo Tyres low max sidewall
 

wondering why the khumo brand tires that you see on most Korean cars these days have such low max pressure rating. its max pressure is only 3 bar or 43 psi. i did notice when i took the company car for a tire change that the sidewalls are very very soft. ive got khumos on my Tucson currently inflated to its max. how much more can i safely inflate them? daily route is about 35 km highway speeds

I run about 50 psi in everything I have from snow tires only rated to 35 max sidewall to 51 psi rated summer tires... I've not had any issues at all.

FWIW, I'm running 70 psi in my 44 max rated tires with no problems.
