Upgrading Rims/Tires: Need help regarding OFFSET, TIRE measurements

[dL10]

good day mga sir/s.

ask ko lang po mga experts natin dito, this will be my first ever upgrade - plano ko kasi palitan ang 16' stock rim/tires (185/55/r16) ng jazz ko.

Balak ko po yung Rota Grid na 16', may mga tanong lang po:

-anong offset ang dapat?
-anong tire measurement ang ok gamitin at walang rubbing? Pwede po bang kapareho ng measure ng stock tires ko which is 185/55/r16 o hindi? Paki-indicate nalang po yung exact measurement at yun po yung hahanapin ko.

**I have no plans on lowering, nabasa ko po kasi ay yung offset ay regarding kung maglolower ng car. kaso nung nagcheck ako sa site ng rota wheels lahat naman pala dun may nakalagay na offset kaya nalito na ako. Di ko magets yung technicalities po.

a little help?

*dL10 you can search 'tire calculator' on google to adress the tire size and rim size issue. what i don't get is how the offset changes e.g. from 15" rims to 17" ones. so, were you able to figure it out?

Para safe sa rubbing, dapat 16x7 +45 offset na rims. Sa gulong naman, kung gagamitin mo ung stock mo, baka magstretch na siya tignan(banat) kasi ang measurement ng stock rims ay 16x6 +53 offset. mas ok siguro kung 205/50/16 na gulong.

kapapalit ko lang din from 17's to 16's sa 1st gen jazz ko at napakahirap mag hanap ng 16 rims na pasok sa specs ng jazz. kadalasan +40 o +42 offset ang meron.

since rota grids naman hanap mo, try mo tumawag sa Rota. Alam ko pwede ka bumili sa planta mismo. At least dun makaka-order ka ng may tamang offset.

offset and lowering are two entirely different things. see diagram below to better understand the offset.



your stock rims is +53 offset. however, you could use +42 as the minimum. choose rota rims with +45. kailangan mo ng mataas na offset para mas pasok to ensure that the tire would not rub the fender. karamihan for the size 16s are +40 only. marami pa rin tire shops na ipipilit sa 'yo na walang problema ang profile 40. sasayad sa fender lip mga yan kahit hindi ka pa mag-lower. sa mga biglang dip or on high-speed, mas pansin na sasayad. marami nang naloko, unfortunately.

magilas already mentioned that you could order higher offset with rota. +48 is the best kahit magdrop ka pa. he also mentioned that you cannot use your stock tires anymore as these aftermarket rims are often wider than stock. if you wish to re-use your tires, get an aftermarket rim with the same width if available. alam ko kasi karamihan ng aftermarket for size 16 has 7-inch width already. I concur with magilas that 205x50 is the best candidate if you'll replace your stock.
