My GP 1.4 Dynamic 2009 Model (~ 35K kms) has 14" steel rims and JK Tornados 165/80 R14. I know it hasn't run much considering 2009, as I was away from my GP for some years, but last year it clocked around 18K kms. Here is my problem, wherein I need expert advice. As you guys must be aware, while driving the 2009 models, there are lot of underbody scrapping due to low GC. I am looking forward to change all the JK's and deliberating on the below options- 1) Upgrade to 185/70 R14 with better tyres, i.e. - Bridgestone, Yoko or Michelin. In this case, GC remains almost same or theoretically, it will be (-) ve 2.5 mm Aspect Ratio: Existing>> 165 x 0.8 = 132 Proposed >> 185 x 0.7 = 129.5 2) Get OEM 15" Linea steel rims with caps and put 195/65 R15 tyres on them. Not interested for Alloys as of now, because of the quality of roads I generally drive here. Not that alloys are not sturdy, it more of replacement costs for defects. In this option, my GC improves by 7.25 mm approx. (not sure whether my calculation/interpretation is correct here) Aspect Ratio: Existing >> 165 x 0.8 = 132 Proposed >> (195 x 0.65) + 12.5 = 139.25 3) With OEM 15" Lines steel rims, which is better option, i.e. - 195/60 or 195/65 ??
