BMW i3 Tires: Get Ready For Winter!

The aggressive tread and the specialized rubber compound of Bridgestone Blizzaks should help me get through all the bad weather this winter brings I live in Northern New Jersey and we can get some pretty bad weather in the winter. The temperatures in January and February are routinely in the 20s (Fahrenheit) and can even dip down below zero from time to time. At those temperatures, you really should have dedicated winter tires for proper traction, even if the roads aren't always snow covered. In fact, most tire experts recommend that you buy dedicated winter tires instead using all-season tires if the average temperatures where you live are below 45 degrees in the winter.

An Aerospace Engineer from the UK Compares the i3 and the i3 REx

What I didn't know was that Lukas is an aerospace engineer. A few of my friends are engineers and the one thing I've learned about them is not to ask a question about something without expecting an answer that involves thoroughly explaining every aspect of the subject. Well, I found Lucas is not very different from my friends! :) His response was about three times as long as any post I've ever put up here and below is actually the condensed version! Warning: We're going off into technical geek land here folks! Special thanks to Lukas for the time and effort he put into this guest post: To REX or not to REX: 24h with the BMW i3 BEV and another 24h with the BMW i3 REX: Greetings from darkest ...
