Ok i have a 04 NBS 2wd f150 that i'm going to be adding a 6" procomp lift to in a couple weeks. I have been looking at either the 305/55/20 nitto grapplers, 33X13.5R20 procomp extreme terrains, or the 35x12.5R20 cooper STT's. I am going to be useing my OEM 20's. Will i have a rubbing problem with any of these tires. I pretty much can rule the procomps out and the coopers are a maybe and the nittos will definatly fit right? Thanks

Also what does the basic procomp come with for the back. 3" blocks? Will that make my truck sit perfectly level?

 

I believe the basic Pro COmp kit will come with a 3 inch block. Sometimes, the kits will sit a little low in the rear. A 4 inch block may be a better choice.
You can easily fit the 305/55-20's (33x12.50). If you are using the oem wheels you can probably fit a 35x12.50-20 with no more than minor trimming.

 

Ok. Know i definatly know the 305's will fit but i want to go bigger and possibly get some bilsteins and raise them up to get 8" of lift. My main concern is that i cannot find a A/T with a 35 inch height that will fit. Nitto and Toyo make a 35 A/T but it is a 325/60R20. That wont fit will it?

The only 35 i can find for a 20 inch wheel is the Toyo M/T and Cooper STT. I love both those tires but they weigh 80+ lbs a piece. They also have a 12.5 inch width. I'm not worring about trimming i just dont want to get the Toyo M/T or Cooper STT and have them rub on the knuckle on turns because i will be useing the factory 20's. Does the factorys 20's allow enough backspace for a 12.5 to work with the procomp lift?


Does anyone make an A/T with 35x12-12.5R20 specifications.

 

I see your point. I don't know if the new Pro Comp knuckles would allow enough room to fit a 325mm wide tire with the oem wheels. Are you gonna keep the oem 20's forever? If you are a couple of manufacturers are now making 285/65-20's (like the BFG AT KO)which are basically a 35x11.50-20 tire.

 

Yea, I know about the 285 BFG's but to be honest i really dont like the BFG's A/T's the KM2's are nasty tho. I really want a wider tire you know. I just ran across some 305/60R20 Toyo A/T's They are kinda pricy but they are a 34x12 and i think that they would be perfect for what i am looking for. They will fit and they are slighly bigger than a 33. So right now i am stuck between the 305/60R20 Toyo A/T and the 33x12.5R20 Toyo M/T. I would get about the same MPG with both. What do you think? A smaller more aggressive tire or a bigger less aggressive tire.

 

Both are great tires. If you don't do any off roading, the A/T's would be a better choice.
