I'm thinking about getting the Cooper Discoverer ST in 285/75r16. These will fit my stock height truck right? I plan on doing a lift later but I need tires now and I don't want to buy 265's then when I get the lift wish I had 285's. Any other suggestions on tire's for mostly on-road and sometimes really muddy off-road. I'm more interested in function over form.
Yes, they will fit, as long as your stock springs are not sagging terribly. Check the FAQ for all the info you can read about what tires and springs fit what.
The FAQ is a sticky at the top of the thread list in this section.
I just put some 285 75 r16 hankook RT3 dynapro m/t's on my 95 the other day. took it out and ran it on some muddy climbs and through some deep soup and it was sweet. Had bald street tires on before that. Great tire for $150 each. Check em out. No problems running on stock heigth with saggy springs. Need that lift soon.
Wondering. When you go away from stock it adds weight in addition to adding height. For instance the Goodyear 285/75R-16 D (3305lbs and 65psi) weighs 58lbs. The OEM Michelin LXT M/S 275/70-SR 16 weighs (2601 lbs and35lbs) 41lbs.
Any estimates on percentage of gas mileage loss with all that weight and lower rolling resistance? Also what kind of pressure do you run with the heavier load tires for grocery getting?
interesting questions. I run mine a little higer than recomended around town. Around 40 lbs. A little more road noise, but better mileage. I will watch carefully to see how it effects wear.

I am rolling on Kumho Road Venture AT KL78 285/75/16. My previous set was OEM Michelin LXT M/S 275/70-SR 16.
Here are my observations:
- gas consumption: over 1K miles I observed approx. 10% gas consumption increase (I added ARB bullbar)
- comfort: I did not observe dramatic noise increase. Due to its 50/50 design the noise is noticeable but not annoying (like sometimes in MT tires)
- functionality: I tested my tires both on highway and offroad (75/25). I am very satisfy from their offroad performance (mud and sand mostly). With new set of 50/50 AT tires my rig became really all terrain vehicle.
It’s really too bad tire manufactures don't list rolling resistance of tires. The 10% mileage loss you quote assuming a 45,000 mile life of tire, 15 mpg (I wish) is 300 gallons of gasoline. At $3 gas this exceeds the cost of tires $900. However since I only put 4,500 miles a year on this vehicle on an annual basis not that big a deal if the choice is between a tire that matches my driving needs (snow & ice and moderate off road) and one that doesn’t. Keeping your eye on tire pressure and alignment would have same effect.
I think Goverrnator Schwarzenegger is going to require a listing for all tires sold in California some time in 2008, apparently not January.
The only rolling resistance figures I could find were on other posts that quote a subscription required Consumer Report review. The LTX had a relatively (for this type of tire) good rating. It would be nice to know how much difference size vs. tread makes. I think I’ll go with 5% of mileage drop on size and 5% on tire.
Where can I get the tires I believe they were on the H1 Hummers? What are they called? They have an up and down tread pattern, look directional like a semi-flattened M. /\/\ tread goes up then down then up and back down. You know what I'm talking about right?
