I own a Vitz 2017 1000cc (yeah the boring KSP130). Wanted to upsize the wheels from stock 14 to 15. Hence, went searching for a good alloy wheel set, and managed to find a set (~ 5kg each). However, was hit by a different challenge. The recommended wheel size to upsize is 175/60 R15, which has a 0.9% increase in the overall diameter. Unfortunately this size is quite rare in SL, and I was not able to find a set till now.
However, 175/65 R15 is widely available in many brands. But, the change of the overall diameter is 3.9% which exceeds the recommended tolerance level which is 3% as I read. I know upsizing will effect fuel figures, that I do not mind a lot. Also the speedometer and odo meter reading glitches are not huge concerns for me. However, being a Vitz 1.0L the acceleration is pretty average now as well, therefore putting additional weight and slowing down the acceleration further is something I would like to avoid if possible.
Couple of questions:
1. If I manage to find a lightweight set of 175/65 R15 tires with low rolling resistance, where the combination of the wheel + tyre weight is approximately similar to what is there currently, would it stil feel slow in acceleration? Anyone who has prior experience?
2. Apart from the fuel consumption, speedometer + odometer readings, any other potential issues which can arise from going above 3% of original diameter?
Does anyone know a place to repair/service a seat reclining (mechanical) system? Seems both driver side and passenger side seats are kind of stuck.. Hoping to take it to a seat cushioning/carpeting place to get checked.. any other option?
Trump imposes tariffs on China and they impose higher tariffs in US products. For the EV batteries China is the biggest provider of earth materials and it will push US EV vehicle prices up. We are going to see a nice game coming up between two world superpowers.
