Ok, so I got a new set of tires for my truck. I got some 33x12.50R20 for my f-150. Oh yeah I traded my stock tires for these new nitto mud grapplers . Right now I am running 325-60/20 on nitto terra grapplers the truck and they did not fit so I have a spacer in there. My question is, will those new 33's fit on the wheel without the spacer. I was told that with my 3" level kit that those 325-60/20's would fit fine, but they did not. So, does anyone know for sure that these mud terrains will fit??!!

 

325s should be alittle too big for stock rims with a 3" level. You should have a rub on the lower front valence. 305s would fit just fine

 

it depends on the rims man. I personally have had the 35x12.5x18's on my truck which is the equivalent of a 325x60x20...no problems and I know lots of other guys who have done the same


You might want to get some 11.5" wide tires instead...unless you already have the 12.5" wide ones.

 

I already have the 12.5 tires. I am running the stock 20inch rim. The reason I am not getting new rims yet is that I don't have 1k to drop on new wheels.... So, I want to know if I can fit this tire on the stock 20 wheel and it fit.

 

yes, they will fit. at worst case, you'll have some rubbing at full lock. but the fender insert can be trimmed to eliminate about 90% of this rubbage

a beefy M/T will contact the upper control arm. but any A/T will be just fine

 

I'm confused, the A/T's I have on the truck now touch the control arm when I have the wheel turned all the way. These mud grappler's, they have an aggressive side wall on them.

 

are you talking about where the center joint is that the spindle connects to?

or where the upper control arm bolts to the frame?


I had 1/8" or so of clearance between the spindle area of the UCA and the tire sidewall. Luckly the tire was big enough that the side lugs were farther away from there...otherwise the lugs would have contacted that.

a Ground Hawg, Baja Claw...and I'm pretty sure the Mud Grappler will contact this area though because of the side lugs they have.
