No sweat. Actually, I just moved from Dogtown earlier this summer. I hear from folks back there that STL got pretty drenched.

 

You're right. I saw them on 4wheel parts' site, but looking back, they're only 32.8" OD, which would make them a 70 series. It is a typo on 4wp.
Too bad, that was gonna be my next set of tires.
Have a set on my DMax that ahs 40k mi on them now with plenty of tread left. Will get 50k out of them easily.

 

Here's the pics. The tire treads are even with the edge of the OEM mudflaps. The bulge of the sidewall sticks out past the mudflaps, but the treads are covered. There's a couple of more pics in my photo gallery, but these should give you an idea.

The tires are the same weight rating as the Toyo Open Country A/T (3970 lbs.). They are much quieter than the stock Bfg's, and I've aired them up to 70 lbs. each.

Looks GREAT & Thank you very much for the pic's & info.

 

Real nice! Hopefully 35's are next!

 

we can always dream, can't we...i wish wish wish wish wish i could find a nice highway tread in a 35" tall load range E...

 

These measure 33.8" - call 'em 34".

Close enough?

 

Not quite the highway tread, but the open country tires in the 285/75R18 measure 34.8" tall, 11.5" wide with an E rating. The trouble is finding 18" wheels with the correct backspacing.

 

truckjunkie-they very well may have to be when i am ready for new tires again. At some point function has to outweigh form and, unless i can figure out a way to adjust the factory TPMS on this '08 so it doesn't trigger the alarm until 45psi all around instead of 65psi front, my next set of tires will either be a 285/75R17 or the Toyo M/T 35x12.50R17. I don't really need a M/T but i have heard good things about the Toyo as far as longevity is concerned. I also haven't had any problems with the sidewalls buckling on these load range D Nitto Terra Grapplers i've got now, but that TPMS light and dinger drive me nuts.

BroncoAZ-good find. i really have no desire to put aftermarket wheels on the truck but if i did, those would be the tires that would go on them without a doubt. Shoot, i may have to reconsider my desire to stay with stock wheels just so i can run those tires.

Now, if only someone would come up with a 295/80R17E (35.5x11.6R17) or a 285/80R17E (34.9x11.2R17) i would be ecstatic!

 

Does the 285/75 fit in a stock 4x4 without rubbing? How much does that throw the speedo off? I need tires, I want bigger, and would like to know how big I can go.

 

They are an inch smaller and an inch narrower than the 315/70/17 that everyone with the H2 wheels runs, they should fit fine on a stock truck.

 

If you have an (I think) 05 or older, the dealer can adjust the pinion factor on your truck from 638 revs per mile (stock 265/70/17) to 596 revs per mile (285/75/17). That will adjust your speedo and odometer at the cost of about $50. I'm not sure about the 06's and up - I thought I'd read they could only go to the 285/70/17 size (617 revs per mile), but I'm not sure.

As suggested in this thread, you could also invest in a Smarty and adjust the speedo with that.

If you leave it stock and add these 75 series tires, your speedo will read about 7% slower than actual.

No rubbing issues with the stock suspension.

 

So I have about 1K miles on these tires now, and I really like them - especially in wet conditions. They will not spin or slide unless I want them to.

But, I have come across an issue, and was wondering your opinions on what I should try first - I do notice that since putting these tires on the truck seems to bounce much more (feeling it through the steering wheel) than it did before. I've messed with the tire pressures some, but it doesn't seem to matter too much. I asked the guys that put the tires on to check the ball joints, and they said they were OK. Also I notice the bouncing only on certain roads and at certain speeds - but it's most noticable at 70 or so on certain sections of highway. Other sections of highway they're just fine (no vibration). I would think if they're out of balance I'd feel the bouncing/vibration all the time, right?

So I'm wondering if it's:

a) just that the sidewalls are much stiffer in these tires and thus I'm feeling more road imperfections

b) the tires are wider and I'm feeling more road imperfectons

c) I need new shocks or a steering stabilizer - the truck has 68K miles on the original shocks - on a side note - how do you check the shocks on a truck like this?

d) ?

Any thoughts? Oh - I did check the lug nuts and re-tightened them all to 135 ft. lbs.

Thanks in advance for any feedback...

 

The 285/75/17s are probably overwhelming your well worn stock shocks and steering stabilizer. They are alot heavier than the stock 265/70/17s.

 

I'm gonna say a. and c. on your list, and agree with surfram about them being heavier...

it's time for some new shocks after 68K.
