I just got my brand new Jazz 1.5 i-DSi after trade-in with my previous 2003 Jazz 1.4 i-DSi (Japan imported). I ordered 1.5 v-tech, but they were out of stock. Anyway, I enjoyed the CVT-7 and more powerful engine.

I am planning to change the rims from 14" to 16" or 17". Will it defect the performance of my Jazz?

 

The 17's will probably affect your performace, and if your car is lowered then you might have some rubbing issues.

Your best bet is to go with 15's or 16's at the biggest. Plus its such a small car 17's would look rediculous.

 

Larger rims will very noticeable adversely effect your fuel economy. Increased rolling resistance has a big impact on this vehicle.

You also have to be careful to maintain the ratios not to completely throw out the speedo. This site will help you recacluate the necessary width and aspect to maintain the ratio. http://www.carbibles.com/tyre_bible.html

 

Thanks for that link, vivid. I just spent about 15 minutes at that page. Good stuff.

 

It seem's that I have to learn a lot more... If the topic about tyres only had took almost 30 minutes for me to read through, looks like I have to take the whole day to learn more about the rest of my Jazz...

Anyway thanks vividjazz for the link. Got more stuff? How about the i-DSi engine? How it works?
