old tyres adjustment depend on tyre condition and brand... mine went for almost nothing due to too old.
yokohama has no issues of smuggling because its been imported in large quantity and almost all shops have real stuff. It comes packed from japan and importer pastes his warranty card. You can easily spot a smuggled yokohama vs imported yokohama... The reason why i had to go through all trouble was because of michelins... Yes 195 is not oem size, it is 185 but michelins were not available in 185. The difference is 2% and according to tyre sites, you can upsize or downsize within 3% of oem size
For urgency, check if tyres have sidewall damage, too many punctures, date of manufacture? tread left? ABS kicks in frequently. Yokohama advan db is 7-7.5k per tyre
Yea that's what i am saying, putting new oil and bleeding the system is supposed to be part of service, ye 3s walon k paisey bana k tarikay han
