Tire Upsize - Which One? The defective tire showed itself. Although tubeless, it had gone totally flat, changed it with the spare one & the wobbling stopped totally. However I am considering an upsize of my tires & have almost zeroed in on Bridgestone Potenza G3. However I was working out the specs to see what suits best & have worked out several options (please check the attached file for the workings, hope I've done it correctly).
To summarize the calculation in the file, the same is as follows:
1. OE Tires: 165/80R13 which would mean that the Aspect ratio in height would be 132 mm & including the rim size (13 inches) total height would thus translate to be ~ 18.2 inches. So to ensure that the CG of the car doesn't go higher after the upsize, stability being a very important factor I considered the following.
2. 185/60R14: The aspect ratio in mm for this configuration would be 120 mm & the total height would end up increasing to 18.4 inches. 0.2 inches more than the OE & Aspect Ratio being lesser in height. - Would aspect ratio being lesser lead to any change in the ride comfort/quality and would being 0.2 inches taller, would that affect stability?
Not sure whether the following two can be installed on a Palio SDX if yes then:
3. 195/55R14: The total height ends up matching to OE fitted tires in this case, however the aspect ratio reduces by 25 mm (almost an inch) - Would aspect ratio being lesser lead to any change in the ride comfort/quality?
4. 195/60R14: Total height increases by 0.4 inches. Aspect ratio is lesser than OE by about 15 mm. 0.4 inches taller, is that safe? Again, would ride quality be compromised?
5. 205/60R14: Total height increases by 0.6 inches, aspect ratio is 9 mm lesser than OE.
Experts, please help. Please suggest the best tire I should go for & whether it should be Bridgestone Potenza or Michelin? |
