37s on new Tundra

You have to do 2 things:

1) Wheels - Get wheels that are 8.5-inch to 9-inch in width (17X8.5, 18X9, or 20X9), nothing wider. The wheel offset is very important. Get one that is between +20mm to +30mm.
2) Trimming - In addition to lifting your truck, there are some additional trimming that needs to be done. If you don't do this, you'll rub and just damage your fenders, inner fender lining, etc. Watch this video to become familiar with what areas under the fenders that need to be trimmed. I hope this helps.
