My wheels + tire weight

[kazuya]

Just to share.. Had the opportunity to weigh the wheels + tires20" taiwan made 20"x10" + hankook s1 evo 285/25/20 25kg (rear)20" taiwan made 20"x8.5" + hankook s1 evo 245/30/20 23kg (front)17" BBS RX 17"x8" + CSC3 245/45/17 19.5kg If I use 17" instead of 20", it's like total of unsprung weight saving of 18kg (or around 144kg static weight saving according to formula I found) The car is faster & more comfort with 17" of course but 20" looks cooler...

I was using 4 sets of rim in a month. This is what i feel even no direct measurement.

16" style 33 > 18" Italy made style 65 > 18" Alpina Softline > 17" style 66

> = heavier

I recalled when I searching for 17", the style 66 is about the same weight as BBS RX...
But with 17" my car often loses power during hard acceleration in cornering (DTC triggered), not fun. Do you experience the same?

No chance to speed yet as the set only up to my car yesterday, but definitely feel the rims are much lighter than my 18" Softline.

20" taiwan made 20"x8.5" + hankook s1 evo 245/30/20 23kg (front)

17" BBS RX 17"x8" + CSC3 245/45/17 19.5kg

If I use 17" instead of 20", it's like total of unsprung weight saving of 18kg (or around 144kg static weight saving according to formula I found)

Thank you for the info ... i've recently change from 18" to 17" wheel, it's more comfortable and slightly better acceleration. Comfort due to taller and beefier side walls compared to 18". Cornering however 18" is better its more sharper than 17". I couldn't imagined if going to 20" lol

Summary: 16" style 33 is suck! Small and heavy! But SOLID!
