Hey I have a 06 Scab FX4 with the stock 20" tires. What's the largest sized tire that anyone has put on one of these? Keeping in mind no lift, no leveling kit, purely stock. Thanks, I tried searching but didn't come up with too much, mostly people who have aftermarket 20" wheels and/or lift's and etc...

 

I have 33" tire on my 20" rims but I have a leveling kit on the front. I'm not sure if it will rub without the kit

 

Would those be 275 65/20?

 

305/55/20

 

275-65/20 would be a 34" tire. The stock tire is 275-55/20 and is a 32", Nitto makes a Terra Grappler in a 275-60/20 which is a 33", that's the same size used on dodges w/20's

 

On the stock 20's without a leveling kit you can run 305/55/20's but you will have very minor rubbing at full lock due to the width of the 305. I am running this size on my 07 4x4 stock height. I really think I could get a 34" under there without the leveling kit, my 33's arent even close to rubbing as far as height is concerned.

 

You could fit a 285/55/20 with no rubbing, it's a little less than a 33" tire.

 

What about more height, such as a 60 or 65? Or does that not really matter? It seems like width is the bigger problem due to the front suspension but have plenty of height room.

 

Back from the dead...

I'll find out if a 34" will fit under a stock 4x4. I'm having my 275/65/20 BFG A/T's installed tomorrow. I'm hoping they'll fit fine. Although, I do plan on leveling it this fall.

 

Could you please pist some pics of your truck. thinking about the same tire setup
