LOL

i havent reprogramed either the 20% # i just pulled out of my a$$

i noticed a big difference between city and highway driving with the stock 33's i had even gotten 21.3 mpg coming home from pismo one time

seems like milage is just the same now if im on city streets or runnin 70 mph on the freeway . i also have a couple hills on my way to work and turn about 5k rpm or more to keep my speed up . as someone had mentioned just have to drive with foot in it a little more thats what sucks the fuel down . i think the days of 20 mpg are gone once we switched to these 35's but its well worth it. i still havent cranked my torsion bars

Don't worry about seeing 20mpg again. I've been running base 32's for 15000 miles and haven't seen more than 18mpg.

If you need the clearance of 35's by all means do it. The extra buck a week for gas won't kill you. But if you are one of many H3 street users commplaining about lack of power the last thing you want to do is mod the truck to have taller gearing via 35's or 37's (slow will just get slowerrrrrrrr).

cool tommy lookin good man

Not as many peeps with 35's as I thought there would be..

What? Am I dead to you???? No programs, no chips.

H3's are good for pimpin in general. Whether its extra bling or extra gnarly offroad equipment. We get to see it all here.

Not totally correct. There IS a program change.

I went from the OEM 32's to the Toyo 33's and the dealership couldn't call GM, because it was Saturday and GM is only open Mon - Fri.

My main reason I was at the dealer was to have my rocker protection installed.

I asked if any GM dealer could do the reprogramming of the computer and they said yes.

The Hummer dealer is over 3 hours away one way and I made an appointment with the local GMC dealer who called GM to get the codes to reset the mileage/odometer reading which also affects the ABS system. Charge was $105.00

Don't know if they can do anything for the 33 - 35 size change.

here's what I'm thinkin'...

There is a program for 33's, but none for thirty-fives. I was at the dealership for 6 f'n hours yesterday. They could not get the TPM to reset

He tried w/the computer, but it would not allow him to change the tire size beyond 33.

That sucks

What? either mine works or it doesnt. I'll have to test and take it down to 20psi.

Morning All

Okay - I got a little geeky this morning after reading the above comments and decided to do some math. Here is what I learned: 315's may negativly change MPG, but not by much, if at all.

Looking at Bridgestones specs the Dueler AT 285/75R16 turns 633 revs/mile. Per BFG the 315/75R16 AT KO turns 601 revs/mile. This gives a "mileage factor" (MF) of 1.053244592. So for every mile the odomiter indicates, multiply that by the MF to get your actual mileage traveled.

You can see in the screen shot below what the adjusted mileage numbers are with the corresponding MPG. It really doesn't seem to make much of a difference.

Ipedog - I like the pic of your H3 up on the short stone wall. I think my wife would get mad if I did that on the wall in our front yard

S. </div></BLOCKQUOTE>

Actually... I'm a very bad man.

This was actually taken in an office park near where I work. I had seen the wall and figured it would be good for testing articulation. So, one weekend when I was in the area I gave it a shot! I wasn't arrested (or havent been yet! ), no damage to the wall, so its all good.

great info on your spread sheet thanks Ipe

That's weird, even when my fuel warning comes on the most gas I have ever put in was about 17.6 gal.

ipe, excellent spreadsheet workup. basically, mileage isn't negatively impacted, it's just what you see on the computer.

when i read the comment that there were no chips or programs, my assumption was that you were talking about aftermarket addons. my most sincere apologies. i'll go away now.

My mileage has dropped to around 15-16 mpg,, but worth it. The 35's really set the truck off. Its no rocket off the lights but it never was. Hey Green, I like your decal alot. I was farking around on powerpoint at work last night for the one I made. Pretty limited on software on our puter. See ya,,,

Don't do that, I heart teh tailgunner

Thanks Guys!

If for any freaky reason you want to track your actual milage this way, PM me and I'll send you the worksheet.

Yea I check my gas mileage at almost every fillup. Kind of obsessive. Always have a little solar calculator and pen in each of my vehicles. Then I write the calculation and mpg on my Chevron gas receipt.

Here is a pic with my MT/R 315's.... I will have some better ones soon.

WOW, snow in Phoenix

hey ket , nice wish we had snow , your truck looks great

Do you happen to know the size of the tires and rims on the red one? And are they BFG muds? Thanks.

hey kracker , are you wondering about the red one just above in the snow or the red one next to mine at dealer , the one at dealer has 33's toyo open country mud terrains mounted on a 20 inch rim not sure the width or make . Kets red one in the snow sets on 35's with stock wheels . my 35's are also on stock wheels that i painted black

And Ketkat, that snow pic looks like fun! I'm hoping to see some snow tomorrow. I was supposed to take my rig out with some jeepers, but they flaked. So I'm going to Shirttail Canyon tomorrow. There might not be any snow but I will post pics either way.

Great pics!!!
