Why should this be in the sd area? Seems to me a PSD owner should be asking his questions here. Also seems there's a little too much bossiness going on here from some.

I came to this area because there may be PSD specific concerns re lifts and tires--AND, I am finding the answers I need here.

Lighten up, Tim. Is your concern the amount of space all this talk takes up? I mean, putting this in another area won't solve that.

 

OOOOF!

With this being the 6.0 forum, I beleive most questions pertain to 6.0's. Lifts, tires, etc. relate to the SD, thus the reason for that forum. I frequent both and enjoy the info garnered from both. And I'm not saying he shouldn't post it here.

Tim, I think it's kind of like the oil preference threads here. Some folks are just tired of seeing them.

 

Tim has already authorized the thread's presence here, after Hjudge voiced his opinion on why he posted here instead of the SD thread.

If there was not a little bossiness going on, this forum would be in just as bad a shape as some of the others, of which we will not name, because everyone would post in total wreckless abandon without a care for order, or anyone else for that matter. Look around. Youll find it.

There is no other particular "concern" with the post being here, other than the fact that it INITIALLY APPEARED slightly out of place. All is fine and well now; let us not start a debate or argument over an issue that is not one; and get back to answering the man's question.

 

word.


anyhoo, 315's, on a 10" wheel, with how much lift? and do you ever wheel this thing?

not a flame, curious....

im learning from many "experts" like the ones that did my lift, all i can dit under my truck is a 35" tire, i have a 6" lift...
seems the problem, and i can see it with my 295's already, is that the tire will hit the front bumper while turning. if you correct this with a smaller backspace, the tires will hit the leaves...... i am a bit cornfused myself.

i would like to find a wheel offset, and backspacing that would allow me to run a 37" tire with my meager 6" lift. i like stability, and i just dont want 8" of lift to run the tire size to get a bit more clearance for this massive sterling rr axle.

anyhoo, not trying to hyjack a thread.

 

Because this is the 6.0 Forum! Tim has the unenviable job of trying to maintain some order here. I don't think it is too much to ask to follow the rules here.

 

Nitto Grapplers are #1 in my book. Darn good tire.

 

I have 315's on mine with 10" rims and the only thing it does is rub the wheel well just a little when turning. The only lift I have is the leveler kit. I had to modify the lower valence on the front end by 1" to clear it. It still looks factory.

 

Just an FYI:

I also experienced a little trouble over on the SD forum. IMO some gassers there seem to think we have nothing to offer. My experience revealed a feeling that some off them think that 6.0 owners feel that we are superior in some way.

Some angry personallities over there.

I bowed out of their silly game.

My 1.5 cents worth...sorry for falling off topic.

 

i bought a 2004 ford f-150 crew cab with the southern comfort package and it has a 315 on a 20x8 rim and it looks good becase the rubber sticks about 1/4 of an inch

 

I stand corrected. But if we are so concerned about posting in exactly the right place, why were we not directed to the tires section? Guess I'd better go back and re-read all the rules, huh?

 

I have 315s on 8" wheels and my friend has 315s on his stock X lariat wheels and they work just fine and look good too.

 

I did a hit and run over there when they were raggin on you. I think it is the same people from the dieselstop that makes it such a lousy forum.

 

Last pic in my gallery shows 315's on stock rims. Suspension is stock with camper package, hope this helps.

You might want to have some one turn your wheel all the way to full lock and look at the tire it will rub the spring usually on the drivers side, and when you run 315s on stock tires it will crown the tire and will cut your tire life in half the least you can run and get a flat tire footprint is 9.5 rim which is usually only offered in the 16.5 rim . you can run what ever you want but you will probably get poor milage. good luck

 

Hjudge49-

Tires - Yes 315's will fit on the stock rim, However they will buldge quite a bit. Most tire manufactures specify at least an 8" rim for 315's. Some tire installation shops will not install 315's on the stock rim, and some will. If you are considering heavy hauling or towing I would recommend going to an 8" rim. Most 315's are not E rated (D), but most have a load rating of 3195#'s per tire (Nitto, BFG, Toyo). This should be fine for all but the heaviest loads.

Rims - Also be very carefull when shopping for new rims to replace the stockers. Superduty trucks require a hub-centric design (vs. lug-centric). Hub-centric wheels have the center hole percisely cut so the wheel is centered on the truck via the hub. Lug-centric wheels use acorn type lug nuts to center the wheels via the lug-nuts. If you read your owner's manual Ford is very specific and cautions against use of lug-centic wheels. With lug-centric wheels the weight of the vehicle is placed on the lugnuts. With hub-centric wheels the load is placed directly on the hub and not the lugnuts. Many run lug-centric wheels and report no problems. I personally haul heavy loads, and often load the bed of my truck to the load rating (camper, snowmobiles on a deck), so I do not like the idea of a lug-centric wheel. Again, just a personal preference, as some are happy with lug-centric wheels.

Superduty trucks have a center hole diameter of 4.93" or 125.22mm (look for a wheel with these specs if you want hub-centric). Bolt pattern is 8 x 170. The downside is that hub-centric wheels are very very expensive due to tooling costs (i.e. since the center hole is percisely cut, and can only be utilized on a few vehicles). Weld wheels makes hub-centric rims for the superduty, so does Alcoa, but there are very few others. Expect to pay 300-400 per wheel for a hub-centric wheel. Also make sure the wheels have the proper load rating for your vehicle. I have seen many wheels mounted on superduty trucks that are only rated for 2,220# a piece! (this is not even enough to support the weight of the vehicle, without a load) - Scary.

Proper backspacing and offset of the wheel are also essential to prevent rubbing and interference problems. Look for a wheel with a 4.5" backspacing. This will keep the wheel offset close to the stock wheel offset preventing problems with steering scrub radius and keep the wheel bearings happy. Wheels with 3&5/8 backspacing are for GM trucks and will push the wheels way outside the fender, and cause rubbing problems at full lock on a superduty with only 3" lift.

If you really want to use the stock rims in conjuction with a 3" lift, you may get a little rubbing of the tire on the leaf spring at full lock. If you offroad heavily a 315's and a 3" lift will producing some rubbing as the suspension articulates. A 295/75/16 would be a better choice if you punish your truck offroad, otherwise I have seen 315's run on a 3" lift.

Sorry for the longwinded post, I hope this made sense and helps.
