Does anyone know if these tires will fit a stock height 4X4 Super Cab. I have a problem as my garage door has a 80" max opening and I think this truck is about 77" now. Thanks

 

KGM, I doubt that you will actually get 3 inches of overall lift by going with 305's. More like one inch + or so.. You have to remember that even though a tire is say 3 inches taller, you only get to benefit from half that number since it is actually only 1.5 inches taller around the circumference.

So if you aren't sure check it at a tire shop...

I did a quick check on a tire calculator website and a 265/75/17 is just under 33 inches whereas a 305/75/17 is just about 35 inches. So your overall body/ride height would only be about an inch, actually a little less with the squat that tires have. With that having been said, an inch in ride height changes the look dramtically and the increase tire circumference is very noticeable, so don't think it won't look any different after you do it....

Hope this helps... and you should still be able to limbo that 80 inches..

Here is a website that you can reference tire sizes..

Chris...do you know the largest tire that will fit on a stock 4X4?

 

I believe the 75 number refers to how tall the tire section is in relation to the width. The section is actually the tire so you have to multiply times 2 (one on top of the rim one on bottom) and add the rim highth (why doesn't that spelling look right?) Anyway, my 305/70/16's fit pretty well. I think you would be pushing it to stuff a 35" tire in there without a lift.

The best way to know for sure is to see if anyone else has done it - obviousley the reason you are posting here. What brand of tire is this? I have not seen that exact tire size before.

 

I've now been told the 285/75/16's are the way to go with no lift. Anyone want to add any opinions?

 

I am assuming you have an F150. Correct?

 

16" Rims are usually SDuty.

 

A 285/75 16 and a 305/70 16 are the exact same diameter(at least with BFG's) with the 305's being a little wider, naturally. I have 305's on 16X10's with no lift and they fit and look simply awesome. The 285/75 looks good on a 8" wheel but IMO, the 305/70 is too wide for an 8" and a 10" wheel should be mandatory. But like I said, that's based on looks and just my opinion.

One question for KGM though, are you sure about the 305/75??? Never seen that size tire before. If that is actually correct, that's a pretty tall tire and I would have to say it would not fit a stock truck. It would be alot taller than a 305/70 or a 285/75.

 

Galaxy...I was wrong on that 75 number. You setup is just what I'm after only I want the KO's. BFG does not make the 305 in this tire. Any ideas?

 

The 285/70/17s fit fine on a stock F150 4x4, many members here have them on there truck. I have not seen anyone with a larger tire on a stock f150 4x4 than this. They may rub when you go over a bump or turn the front tires tigher. The 285s are a touch over 33" and those are about 35". So thats an entire 1" more all around of cleareance that you need...

It would be intresting to know if anyone has put 35s on a stock 4x4 even with the torsin bars adjusted.

 

I did some research on this and found that this board has 2 members (with galleries) that have the Goodyear MT/Rs 305/70/17s on there stock 4x4s.

This one is a screw...

So apparenly it is possible. Not as much clearance so I would have to ask them, but as far as the 305/75/17s go they are 35" in diameter and these are 33.8" in diameter. You can see how close they are, so the 305/75/17s may not make it.

 

Here's what I was told today when I went to 4Wheel Parts by what I thought to be a knowledgeable salesman. The 305/75/16 will rub with a 10" rim, even with a 3" body lift. Also FYI they now have the 3" kit for adjustable pedals. He said you must remove some of the plastic at the lower part of the valance for the 10" rim not to rub. He claims the 285/75/16 on a 8" rim will work on stock height, and the 295/75/16 on a 8" with a 3" lift. I still am not sure which way to go, I love the look of the 10" but I like the way the mud flaps keep the truck clean. Will the wider tires throw crap all over the sides of the truck? Anyone else with an opinion?

 

I think the stock factory Ford 17" rims are 7.5" wide. The Goodyear 285/70/17s and the BFGs (same size) both state that they will fit on a 7.5" rim. The Goodyear has some very good reviews and is a bit cheaper than the BFG, it is supposedly quieter but has a softer rubber so I don't know what kind of life it will have, the extra traction should be worth the shorter life??..

At almost $25 less a tire I think I will be going for the Goodyears. As far as size goes, the 285/70/17s are in my future, now all I have to do is get that Money set aside, just a minor setback. Hmmm how good is the security at the goodyear tires plant???

It seems that it is a lot easier to find tires in the 16" rims vs the 17"s

 

Plus, for people with the factory wheel, 7.5" wide is not all that great and narrows your options further. Well, not really though, cause like dcovell said, there's not that much out there to begin with. That's why I changed to 16's.

Anywasy, FWIW, I was at the dealer yesterday and they had a brand new truck that they fixed up to sell and it had Explorer Pro Comp all terrain tires on it in a guess what....315/75 16 on a 16x10 AND...no lift kit at all. Just the torsion bars cranked up. I spent alomost 30 minutes looking under this thing to make sure I wasn't missing some stealth lift kit or anything but she was bone stock. They didn't have the bumpers trimmed or anything. So, I guess if you have a wheel with the right offset or something it will work. I personally didn't like the looks of it. The tire is too tall for that truck when it's stock but that's just me. But they did fit.

 

Hey thanks for the tire calc web page, it's the best one ive seen, I just leveled my truck and put 305/70/18 under it and it doesn't look right, the tires don't fill out the wheel well, so Im thinking stay with the 305 for the just go up to a 305/75 or 305/80 if there's no rubbing, it looks like I have more then an inch and a half on each side so it seems like it would work out.
