Thanks for the replay. I appreciate the time you put into it. Don't worry about the rambling.
That's a heck of a lot of info there. The offset info you gave me is priceless. I'm really glad you posted here. I'm thinking of going 35x12.50x17/18 AT for ride quality & ability to stop and keep traction in wet environments. I understand the repercussions of moving to a larger tire (speedometer won't read true & there should be a mileage hit).
Is it possible to get a tire with those dimensions to fit with a negative offset?
