Tires/replacement tire/wheel


can I replace original tire/wheel 205x55x15 by 205x40x16 without compromising safety?


No, you would be compromising safety.  The load carrying capacity would be less and that leads to tire failures.  Very bad.

May I suggest you look up your vehicle on Tire Rack and find what tire size they say will work - both in terms of load carrying capacity AND physical space under the fenders.

I have over 30 years experience in the design, manufacturing, and testing of tires. I have served as the technical advisor to the "800" number. I have authored or co-authored many publications - usually without credit. I can answer almost any technical question, but please don`t ask me to compare brands. I probably have prejudices because of my work experience.
