How much air pressure should you run on 305/70/16 tires?
I had tires rotated and the shop had them at 35psi. That was just too low and didn't drive well. I have about 42psi right now and they drive better.
I've heard everything from 35-50psi.
What do you run?
" Michelin LTX A/T 2 Load range E tires that are size 265/75/16"
I don't haul much and I don't tow.
How much in the front tires and how much in the rear?
Had the tires balanced, still shakes. Had them balanced and tires rotated on the wheels for optimum placement. Still shakes, no visible bubbles for tread seperation. What to check next?
View 6 RepliesI do 98% of my driving unloaded and almost never tow. (Kinda weird for an F350 huh) I know that the truck recommends going with 65psi front and 80psi rear but the rear tires seem to not be wearing evenly across the tread pattern. The edges still have the little rubber stubs sticking out of them even after almost 3000 miles. Should I be running a lower tires pressure in the rear when empty or should I just let tire rotations take care of the uneven wear. If I should air down, what pressure would be recommended? The front tires are wearing normally at 65psi and they have more weight on them then the rear.
View 14 RepliesWhat is the cause of my New Tires are starting to Cup and or Feather pretty bad. Is this a aligment issue? Camber? I am just not sure because it feels like the truck drives Normal...
View 9 RepliesI have an 05 Excursion Eddie Bower. Ordering new tires tomorrow and trying to figure how large of a tire I can fit on my factory rim without any issues My Excursion is completely stock!Going with the BFGoodrich All terrain K02's. I was going to go with 315/75R16's. Is that too big? Will I have rubbing issues? Will that fit the stock rim without any issues? Or how about 285/75R16's if the 315's are too big?
View 14 RepliesMy Excursion only has 74000 miles and I just replaced the original shocks with Monroe Reflex and combined with my Goodyear Silent Armor tires was running beautifully. Then after a "deal" from Ford, I replaced the Goodyears with LTX-MS2's and had the alignment checked since my Goodyears did have a little cupping after 45000 miles. They also checked all the front end components and said that everything was in good shape! Upon driving it home, the Excursion steering was extremely loose and I was ready to return the tires and get new Silent Armors, but I figured that there probably was something screwy with the alignment that they just did. So I brought it back, test drove it with the tech at 75 mph and he decided he needed to recheck the alignment. After the realignment, it drove beautifully, but after reading the posts on various forums regarding the proper toe-in on the front, I am questioning whether the alignment is set properly?
After the 1st alignment (in degrees):
LF Camber .3; Caster 3.0; Toe .01
RF Camber -.2; Caster 3.2; Toe -.03
Total Toe -.03; Steer Ahead .02
LR Camber .1; Toe .12
RR Camber -.03; Toe .16
Total Toe .27; Thrust Angle -.02
After the Realignment (in degrees):
LF Camber .3; Caster 3.0; Toe -.03
RF Camber -.2; Caster 3.2; Toe -.04
Total Toe -.07; Steer Ahead 0.00
LR Camber .1; Toe .13
RR Camber -.3; Toe .18
Total Toe .31; Thrust Angle -.03
Just put new tires on my excursion 4x4 powerstroke and I'm getting cupping just on the inside of both front tires it already has new ball joints and steering box tire rods are tight and all joints in the front. what else could cause it?
View 1 RepliesThe stock 265/75/16 tires need to be replaced and I was considering swapping 285's on the stock wheels. Will I notice an increase in fuel consumption? I realize that calculating mpg will need to be adjusted due to larger tires since the speedometer will be slightly off.
View 14 RepliesI recently purchased a 2000 Ex Limited 2wd. It is stone stock except a slight lift. This lift gives it a pretty significant rake that I'm not a fan of. I'd like to get this thing leveled out without spending a fortune and I believe that would require the knowledge of the FTE.
The pictures below show the rake and existing suspension mods. With 285/75 16 Tires there is about 6" clearance from tire to fender on the front and 9.5" in the rear. It has a 2" spacer under what I imagine is the stock front coil spring and a 4" block below what do not appear to be stock leaf springs (guessing because the anti wrap spring is not present).
I'd like to get the front end to sit about 3" higher than it currently is to better match the rear. Lifts of any type are foreign to me. What front springs (and other components) do I need (and what brands would you recommend based on hard earned experience) to make this thing work?
Started my treg this morning and got the tire pressure warning. Cchecked in convenience setup to see which one had low pressure, and it indicated all four tires were low. Filled tires up and checked pressure again (manually using digital gauge) and they were correct. Started up treg and still got tire pressure warning for all four tires.
View 4 RepliesJust bought a 2001 v10 ford excursion limited with 127xxx miles. I have a few questions.
1. I can't get the front tires to rotate while parked and stepping on the brakes. I thought it was caused by the 35 inch BFG goodrich all terrian tires and a lift kit i dont know how tall but apparently i'm just a sucker. From the searches i did, i think the problem is that either the power steering or brakes doesn't have sufficient pressure to power both at the same time. what is the fix to this?
2. I found metal shaving in the rear differential. For lack of picture, the best i can describe it is that it looks like shaving off an ice block. Also, the fluid is gray and consistency of sludge. I searched and some said the shaving is normal and others said fix now. Which is it? I assume that the rear differential fluid needs to be changed.
I have a feeling my 2012 C 3 may have low tire pressure. One of the tires looks kind of softer. Is there an indicator that warns when it happens?
How in general do I approach this? For the past few weeks my mpg was low, barely making it into low 40's. So, I wonder if the tire pressure can affect the mpg.
So had some new shoes but on the car, but the next day after having them installed the air pressure sensor tripped. Anyway i can somehow reset this without a (sigh) trip to the dealer? By the way, yes, I did check the air pressure levels and they are spot on.
View 2 RepliesI have read many of the comments re tire pressure loss but don't know if I have a unique problem or not. I own a 2011 GMC Terrain and my tire pressure is monitored through On Star. Every report I receive tells me my pressure is low in all tires - about the same amount, with little variance. Fortunately I own a air compressor and add air - virtually every 10 days or so.The dealer tells me all tires have small pores which cause leaks and I should go to a tire firm to have nitrogen put in the tires. (He didn't say it would seal the tires but indicated it would solve my problem?) Almost all of the comments on your site do not speak favorably of this. Any thoughts?
View 19 RepliesLast week I had new tires installed on my 18" Samarkands and the TPMS light has been on since. I've verified that all four corners have the metal TPMS sensors in place and the tires are at 40psi, spare is 38psi. I have driven over 100 miles since the tire change. In past the light would come on when pressure below 36psi, and would turn off when tires inflated.
Have this problem after a tire change? Are the sensors easily damaged? Discount Tire/America's Tire Store said to bring the car back so they could take a look, but first wanted to get Vortex input.
I just got 4 new tires installed, running 235-40/18 setup (stock wheels.) On the drive home, the flat tire warning sign came on. I've tried to used the SET button in the glove compartment to deactivate it. That did not work (it flashed one time then stay on).
I check the pressure on all 4 tires and they're all at exactly 40PSI. What the problem could be and how to turn this pos off without going to the dealership?
I am getting tired of these idiot lights. Now its the low tire light it comes on every time I drive and the tires are all up to pressure. I cant find a way to reset.
View 14 RepliesI just bought a used 2008 Prius Touring model and it has Bridgestone Turanza EL400 02 tires. Max pressure says 51 psi.
What do you recommend for tire pressure? I read a lot of posts about 42F/40R. Is that for all tires?
Because of the cold weather my tires went a little low in pressure and my light came on. Now i set all the tires to correct psi and light is still on. is there a way to reset the light without going to the dealership? went through manual and says nothing about resetting light.
View 24 RepliesI am aware that cold weather will decrease your tire pressure, but what is throwing me off is how quickly my rear tires seems to be losing pressure?
I park outside overnight, and it gets down to about 25 degrees F here at night. My front tires I run at about 38-40 PSI, and I JUST filled the rears up on Saturday to the same. I start my car this morning and both my rear tires are sitting at 30 PSI. This has happened ever since the dealer took my my wheels to refinish the rims about a month ago. Is there something they could have done that would be causing this? The can't think of a reason as to why the front tires are fine and the rear keep loosing pressure.
