[Rogersk8ter]

If my tire spec is 215/60/R16, can i change to 205/60/R16?

 

what are the consequences?

 

save abit of tires cost?

 

save abit of petrol cost?

 

danger due to reduce spec?

 

etc....

Smaller diameter tyre.

So can accelerate timing faster

Lower CG, theoretically can karp corner more stable.

Hmm.. is about 1.8% in speed difference.. So should be ok.. just make sure when change tyre to different spec, the speed difference must not be too great difference.. as it will affect a lot of things.. I also not sure how to explain.. maybe more expert could explain more clearly and why it is important to keep within certain speed % difference and not varies too much.

Speedometer will read faster,fuel comsuption will go up[more turns per KM],more gap between the tyres & the fenders,stick to the standard size the best.

FC may be better with the lighter

FC may be better with the lighter tire. May need to inflate tire with slightly higher pressure.
