Trailer Tires
Honestly after driving for at least 35 years now and trailing almost all of that. The nitrogen thing seemed to be a fad in the NE. It was hot and heavy back in the 90’s and died because “I won’t pay for air.”- general consumer.
Honestly with trailer or truck tires, I only get maybe 1 year of driving out of tires. Due to work mileage that is. So nitrogen is not really helping me. But I do like the green caps! The average truck mileage is 30k per unit and trailers are like 15-20k on a set of 4. I can tell you that I was stopped one time on I95 near New York and they only looked to see if any tires were “LT” and I asked “why”- they just said “move along sir.” I did not get my answer. All my trailer tires are “S” which also has UV additives in the sidewalls to help protect from cracks while sitting.
