Just purchased a 2008 lariat in dk stone. Looking to put some new tires on. what is the largest tire size i can go with my stock set up. the wheels are
20"'s. Thinking about going with the terra grapplers. thanks fellas

 

305 55 20 i think that's a 33 12.50

 

Really? Man that's a big tire for stock. Sweet
So that won't rub or stick out side fender flare?
Thanks that's got me really wanting to get tires now.

 

As far as I know on a stock 4wd that will fit. I haven't done it myself though. There's a sticky all about tire sizes.

 

can someone post the link to the sticky that says what tire will fit the 20 inch rim and stay inside the fender flare. i cant find it. thanks

 

Need a leveling kit for 33's on a 2WD.

 

its a 4x4 the tires on there now are 275 55 20 so i can go bigger than that correct and stay inside fender flare. i want the nitto terra grappler

 

If you are going to get bigger tires (34-35"), you need to think about re-gearing. That's a minimum of $800, possibly closer to $1K. Otherwise you run the risk of putting a lot of stress on the transmission.
