I usually maintain a tyre pressure of 34-PSI at front and 32-PSI in rear, i hope it is correct for chevy optra. Earlier i use to keep 32-PSI in front and 30-PSI in rear, which resulted in low pickup and heavy moving. Upgrading the tyre pressure helped in avoiding such problem.

This could cause vibrations while braking.
Check your tyres for damage/tread wear/flat spots and replace if necessary. |
I am on stock rims, i am too even somehow inclined towards getting the alignments and balancing re-done which was initially done in showroom at the time of service around 4K kms back.
Rear tyres were checked for the damages and punctures on last weekend only, as this week's tour was in cards from last month. Tyres were fine without any damage or flat spot.
