1. What is the "stock" tire size for a 2000 F350 7.3 Super Duty 4x4 SRW?
2. Is there a way to adjust PCM to accommodate different tire sizes?
hello, so yesterday at the local gas station I was talking to a guy who has a new, nice looking GMC 1 ton 4x4 nondually truck. we started talking about milage and he told me that going up 2 sizes and adjusting it in the onboard computer he was now getting 22mpg.
so I know this isnt an apples to apples kind of thing, and I do know that for example on my F250 it is geared to haul... but has anyone got real data on getting back down to a 3.55 gear adjusting tire size? has it made a difference ? especially if it is just a DD and not a work hauler. yes we all know if you go too far milage gets worse, but I always found for a non-work truck that the 3.2-3.5 rear gear ratio or equivalant eith by changing gears or tire size was a sweet spot for MPG.
right now at 13K I get about 17-17.5 mpg unless I am driving on the interstate and then I get a tad more.
thanks Fert
I have a 2007 f150 XLT with 18 inch stock rims. I also have a 2 inch leveling kit, how big of tires can i put on it?
View 6 RepliesI have a 2003 excursion 4X4 on factory 16" wheels. I want to keep my same wheels. Want to install 7" lift. How big of tire can I go? I was looking at the 345/75R16 and 365/75R16 BFG Mud Terrains. Not many manufacturers are making big tires for 16s. I want to go as big as I can without cutting or spacers. Will NOT put any type of Super Swamper. This truck will never see mud.
View 5 RepliesTime to replace the aging vacuum lines to the 4wd and probably anywhere I can find the old rubber stuff.
What is the size of the lines and are they mostly the same?
I'd like to order a roll so I can make ones like the front hubs longer, stuff like that.
So my brother in law calls me because he is stuck in the mud. I back up to hook up to him. One rear tire slips into the muddy rut. Other tire is on dry hardpack. The tire in the mud spins non-stop. The tire on the hardpack wont move.... I feather the brakes as I have read it will engage the truetrac. Nothing.... Is this thing junk? I was super ticked off. How do I test the truetrac to see if it still works?

View 7 RepliesWhile turning very slow and sharp on the farm, I heard a pop under the hood. I then lost power steering and brakes. I saw power steering fluid spurting in the left tire well behind the tire. Look under hood and saw fluid coming from a fitting on the side of the power steering pump. I have attached a photo....one photo with nothing and then other with a screw driver tip on the fitting.
It appears that the the pressure fitting blew out the side when I turned sharp. It has a nut from which it came (compression of some sort?). I can push the nipple of the fitting back into the nut but I guess the pressure is gone.
OK, so a friend's F150 just went up in flames in his driveway and he told me that the problem was the hot link behind a plastic/ rubber barrier at the main brake cylinder. I had a recall notice on my old truck but since I left the US and took the truck I never paid much attention to it, thinking typical overkill. Now I already heard from another buddy who caught lit brake fluid dripping onto the front tire and got the fire out before it spread and looked up the info today. Looks like our trucks are affected. Best to unplug the harness that goes into the brake master cylinder will prevent this problem from occurring? I never use cruise where I am, the roads are too small and slow.
View 6 RepliesIm just about due for some new tires before this next michigan winter. I have 18" rims with the stock 275/70s. What size can i go up to with out any trouble?
Also. I have michellin ltx/2 now. Mostly highway miles with some muddy job sites and also to my 8000lb camper 6 times a year.
I just see a fluid by the front passenger tire leak when the diesel is running and ac is on.There was fluid up by both aluminum lines going into a plastic canister in the engine compartment on the passenger side.I couldn't find any cracks in the hoses or aluminum lines..The plastic canister I believe is (AC ACCUMULATOR ) did have a hiss of air when I shut the truck off. I can't see where the clear liquid is coming from. Just started to leak by the front passenger tire.
View 3 RepliesI have reset my tire sensors twice and the low tire light would still come on, so I called the dealer today..he said you have to set the tire pressure to what is on the door jam.
65 psi front and 85 psi rear. I did not know that. I had been setting all to 65 psi.
Thinking about buying 2007 XLT Supercab 2wd with 235/70R17 stock tires and wheels. Have no plans at this time for a lift.
What would be the largest tire size replacement i could use in an all terrain tire? (thinking about BFG or Bridgestone Revo)...
just installed all my intercooler boots with plenum inserts. Had a torque wrench set at around 14 lb/ft and all of a sudden POP! the inside of nut on clamp stripped out. of course its on the boot going to the plenum. Any one have this happen? Brand new clamps from riff raff. Am I cranking to hard, maybe torque wrench isnt accurate, i don't know but didn't seem like i was getting on it enough to do that. the threads came out on the bolt looking like a heli coil. not to cool. Google it and another forum popped up , everyone was saying to crank em down. apparently you cant do that , not even 14 lb/ft. Anyways went to hd and threaded the bolt into their thread gauge. the only one that seemed to fit was 1/4-28 fine thread( which they don't carry in a nylon thread lock nut). Is this the correct size? How to gauge how tight to tighten the nut?
View 4 RepliesI just had my turbo and the EBPV on the pedestal rebuilt. Now I need to put it back into the truck. What is the procedure, if any, to adjust the EBPV? I only use the truck to haul a 5th wheel RV and the performance chip closes the EBP valve when going down steep hills -( EXHAUST BRAKE)
View 6 RepliesHeater control will not adjust, the one in the middle. I can turn it up and down, but it doesn't affect how much heat the heater is putting out. The other two work correctly. Do I have a bad switch or is the blender valve sticking? How can I tell? '99 F350, 1.25M miles.
View 1 RepliesSo i bought a Aluminum Flatbed to replace my rotted bed. Its about to blow off going down the road at this point. The new Flatbed is Aluminum with LED lights. I suspect i will need to wire in a load reducercorrect? Also this bed has no fuel spout so i need to fabricate something. I also plan on installing underbed tool boxes if there is space.

View 14 RepliesMy leaf spring swap is almost complete... its been almost 3 weeks with all the conflicts of life but its getting near completion. Just have to do front passenger side now.. Tomorrow and it should all be done.. hopefully... Any ways... my preliminary numbers are 40" front (ground to fender) and 41.5" rear.. Might be 1/2" to 1" off since I haven't finished the job AND the truck is sitting on dirt. Any ways, What size wheel/tires can I fit on there now? And will I need a spacer with that size?
View 1 RepliesI was wondering what the maximum size tire with no lifts or leveling I could put on my truck would be. I was looking at a pair of Nitto grapler g2's at 295/70r17 with my stock wheels. Would that fit?
