Static problems do occur on gas trucks,usually after the customer has switched from standard to white non-marking tires...the non marking tires don't ground the ruck to the floor and the operator usually gets a nasty shock getting on and off the truck...I had a customer that switched and I installed chains on all the trucks I used heavy 1/4 thick linked chain as it dosent wear as fast....I made them long enough so that there was 3-4 links laying flat on the floor underneath the truck....mounting point is up to you,wherever you have access to I guess
