    185 - thread width / tire width
    55 - % of thread width as tire wall (height) 185x55 = 101.75
    r15 - wheel radius 15"
    82 - load index 475 kg
    v - max speed rating 240kph

    once ibang size ang kinabit na tires versus sa stock specs.. speedometer readings will not be accurate.

    185/55/R15 - Current rolling circumference 1762.81mm

    195/55/R15 - New rolling circumference 1795.98mm

    difference = 33.17 or 1.88%

    cruising speed of 60kph is actually 61.13 kph

    share ko lang experience ko dyan sa changing the tire size.. stock size 145/70/R13 on a 5.5" wide rims, palit ako ng 175/60/R13 on a 6" wide rims

    The result, sayad sa rear fenders pag 4 passengers sakay.. since yung stock specs ay hindi usle sa body nung car at yung new specs ay nakaapekto sa offset ng wheels. The solution suggested ng casa - return to original stock specs.

    My solution - since i like the wider tires, i installed lifters. sa pagpapalit ko pa lang ng tires tumaas na ng 3.5mm yung tire wall plus around 1 and a half inch na lifter.

    In your case, I dont think 5.5mm increase sa tire wall/height would be enough para sumayad yan sa fenders/body since you are maintaining the same rim width... minimal lang un eh

    possible din because of the width of the rims + wrong offset.

    with regards to rolling circumference....is there a way to calibrate the speedometer kung sakaling baguhin yung tires from stock to a customized size?
    if yes, saan po ang shop? TY po Masters!

    thanks mga sir, clarify ko lang, does this mean mas malapad ang 195 vs 185? di po ba mas maganda kung malapad ang gulong kasi mas stable ang takbo ng auto? yung height, yan yung sukat from the rim to the thread? yung wheel radius yan po yung sukat ng rims? thanks!
