Should be in the 15kg area, 33lb for the 17”.
That is what the Toyota steelies (17x7) are quoted at.
Good data point to reference, thank you!
I plan to put 35x11.50R17 Toyo AT III on which ever 17" I got with, they weigh 63lbs each so if I weigh 93-96lbs per corner I'm good with a 13-16lb increase from stock given the overall size increase and swap from P to LT tire.
