Tire Off Set Info

I have a 07 Crewmax with Bilstein on top level giving me 2.25 lift in front. I have been told I can run 34's with the right off set...

Here is my question- If I have neutral or even negative offset can I run a 34x 12.5? Does anyone have experience with this? Can I run a wider tire by pushing them out? How do I best figure this out without buying several sets of tire and rims to see what works? Thank you for your time and input.

 

You should check the wheel and tire forum here and look at the different setups in the thread, also check the suspension forum for tons of pics and info onthat size or 35 tires.

Generally, a wheel with about +25 will be near your sweet spot for that size. For comparison, stock wheels are +60. The lower the number the more the wheel and tire will "stick out" from the truck.

Lots of people running around +25 with 34, 35 inch tires. Too little offset and you risk hitting the UCA. Too much and you will rub other parts like body mount, plastics, flaps, skid, etc....you get the idea.
