Anyone know, will F-Sport 18" which just launch to specific AWD model can fit with RWD model?

Some street of my country thus I may go for weekend trip may not suitable for 19" Wheel which available for RWD model.

So, I had plan to change my order from F-Sport 19" to F-Sport 18". Will they work with RWD model?

The spec of F-Sport 18" Wheel Set ;
18"x8" , offset 40mm

They recommend to use 225/40/R18 for all of wheel. But Can I run the width tires such as 255/40/R18 with this set of rear?

 

yeah it should be good..... but the rears... i don't think 255/40 will fit... mayyb 255/35

 

At here, 19" tires are not easy to find because the road condition were not good enough. Especially, the price is very high around double from 18"
