My wife taking kids up to mountains for snow fun. Snow chains recomended. She drives a RWD Infiniti EX.

Does she need 2 or 4 chains???

thx in advance

 

You only need chains on the drive wheels. Make sure if you have not used chains much that you drive a very short distance and see that they have not become loose. This is common. You will then need to tighten them up.

Also make sure to get the rubber band tighteners. They help make sure the chains don't get thrown off and damage the vehicle.
