KNEW IT! You tried to lie to me
Honestly I can't see the 37s weighing much more than anyone elses 35s, they measure out at about 36" on a truck and are only 12.5" wide. 8.6" rear would help though, and I hope you at least have the 4.10s...
They are not good on the road, from what I've seen, be happy to get 10k out of them, but at 100$ each its not bad.
You beat me to 37s, that was my plan once these tires wear out
