Crawl Ratio
Crawl Ratio : Crawling is how slow you can go offroad - this is especially "helpful" on rocks - thus the name "rock-crawling". As a rule of thumb you can say you have a decent low range when your crawl ratio is over 40:1, but if you are into real offroading and run bigger tires the aim is to go over a ratio of 70:1. It is not strange to have specialized rock crawlers with crawl ratios in the 200:1 region!. Enter your values on the left side, press Compute and your answer will be on the right.
