As I said in the PM, as long as you are leveled you should be good. That tire measures out to a 34.5"x12" so it is 1" over a 33, which usually equals out 32.5" round on the truck. My 33s are currently worn down to 32". I am going to buy the same tires and I am not expecting any rubbing or any possibility at all, but that is my 2007. I will of coarse level, but only 2". It will work!

 

Thanks, I may do that. Appreciate the offer.

Yeah thanks. I did some calculations last night. Think I did it all correctly. This is what I came up with.

Based on stock wheels & tires:
18" diameter
7.5" wide
+44 mm offset
32.1" diameter tire
10.8" wide tire

With the 305/55/20's and XD Monsters:
20" diameter wheel
9" wide wheel
+18 mm offset
33.4" diameter tire
12.6" wide tire

According to my math, the overall setup would be 1.3" more diameter than stock, stick out roughly 1.8" more than stock, and gain me 0.22" of clearance on the suspension side of the wheel compared to stock.

With the 295/65/20's and XD Monsters:
Same wheel specs
34.45" diameter tire
12.13" wide tire

According to my math, the overall setup would be 2.3" more diameter than stock, stick out roughly 1.6" more than stock, and gain me 0.44" of clearance on the suspension side of the wheel compared to stock.

Now based on that, it seems like either should be fine. Now just have to decide which look I like better. Haven't decided if the 295's look too stuffed with just a level. I've always wanted to get close to 35's, but not sure if its overkill here. Darren why don't you just pull the trigger already since you have the monsters and I can get a proper image even though not the same body style! Haha.
