What is the biggest tire size I can fix under my 2006 Quad cab 4X4? Thanks for any help.

 

315's (35 in.) are the biggest size most stuff under stock 4x4's. Some get slight rubbing on the control arms, some dont. Nothing a leveling kit wont get rid of though.

 

Just like dodgeman stated but keep in mind that's with stock rims or rims with a hell of alot of back spacing and you'll need a leveling kit..

Hope that helps...

 

With stock rims a leveling kit will not help the control arm rub lifting the front does not move the tire out from the arms. However you will want to consider this if you opt for the 315 70 17 I am runnin this size with out a kit but want to get one on before i go off hwy its pretty tight to the fender. 285 70 17 are good especially if you have an auto.
