Lightweight Rims And Tyres

Recommended Posts


I heard that with lightweight rim and tires we can improve the pickup of our cars (IS200).

1. Is it true and by how much?

2. What is the weight of our stock 17” rim with Dunlop SP9000?

2. I intend to upgrade to a 6.2kg rims with light weight performance tires. I am not sure what type of lightweight performance tires there are out there. Any recommendation? Will these configuaration provide better performance?

3. Is Continental SportCompact 2 and Yokohama AVS dB a lightweight performance tires?

4. Which one is quieter? Are they more silence than Dunlop SP9000?

Any weight saving will improve performance but because wheels/tyres are a rotating mass the weight saving is about 4x the actual weight. e.g. if your wheels/tyres are 25kg lighter it's about the same as removing 100kg from the car.

AVS dB are quite, much more so than the SP9000. Wouldn't think they are any lighter though.
