Tires are we tired of them??

acf,

>> because it will throw "the computer" off <<

Technically he is correct. There are a lot of computers in your vehicle. There is the computer that controls the shifting of the tranny, the main ECU that controls emissions, the computer that tells the SRS how fast you're going, and more.

The easiest solution is to acquire the speed sensor gear that Christo sells. When running 33" tyres (285/75 or 305/70) it will put your speedo and odo very close to actual and it's an easy install and relatively inexpensive. The tranny will shift at the proper speeds and all sensors and ECU's will be accurate.

That being said, it's not a big deal and I seriously doubt there would be any problem without the VSS gear change.

Thanks, Beowulf, called the dealer for grins and their service dept. told me flat out not to do it.

They would indeed say that. As a representitive of the manufacturer they can not recommend modifications. Doing so infers liability if something doesn't work right.
modifications of the vehicle as produced are at the discretion of the owner (within the law, IE de activating emissions and so on) and are done without blessing from the manufcturer or the dealer body.



What I can't quite figure out is how come every body is buying rotors for their 80's and pads for their 100's at the same time............. That doesn't make sense to me

Hey Dan, who's the guy doing a package check?

 

[cruiserdan]

That would be General George Simpson Patton JR.


You'd need big ones to do the job he did...

Brent,
That looks really nice. Is that stock suspension? I just ordered mine today ( Revo 285s) but its in back order maybe a week or two. Can't wait on mine after seeing the before and after pics.

I've replaced the OEM shocks and springs after 10 years with Rancho 9000 shocks ( use setting 6 of 9) and OME 861/862 (I think) medium duty springs. Springs lifted the truck about 3/4", tires another 1 1/2".

Just back from a 540 mile drive to Needles for some canoeing with the scouts down the Colorado River. Road manners of the 285/75/16's were very nice. I'm happy with handling and looks!

Cruise control saga was intermitent. It wouldn't work, rest stop shut off engine, back on freeway and it would work.

Haven't done any speedo recalibration yet. Speed test with OEM tires - 65mph on speedo 62-3 on GPS. Tested on way home this weekend with 285's going a little faster so I wouldn't be run over on I-15 back to SoCal - had cruise set at 74 on speedo, GPS read 76-7mph. There is a definite change in the speedo from reading to fast from actual GPS calc'ed speed to reading slow compared to GPS speed. Just as expected based on the tire calculator. 77 actual vs 74 speedo = 4% variance. I'm ok with that. Curious if my mileage on odometer is also affected???? Assume it would be, but don't know. Anybody care to answer this one?

Thanks! There are a few of us that heartly agree with this statement!

green..........that's the cat's meow!

>> Curious if my mileage on odometer is also affected???? <<

Yes, same percentage as the speedometer. This was one of the main reasons for adding the correction gear. If I ever sell it (no plans) I can sign the mileage disclosure certificate with no reservations.

That's what I was afraid of. The speedo correction module Christo sells correct all that, right?

 

[Beowulf]

Yes, and very effectively in my case. GPS = 75, speedometer = 75. Since your truck was off to begin with it might not get you back to actual but I think he lists the % of correction supplied by the gear.

The best solution is what Rick, Tyler, and others have done and that's the Tru-Speed. It will also let you have 2 settings for when you get those 35" tyres. You *know* you want them.

[Brentbba]

Thanks B. Will look at the Tru-speed as well.

285's is all I'll go. We'll leave the 35's for the rest of you. Besides, I wouldn't fit her into the garage anymore, so I couldn't call her a garage queen any longer.

Easy, raise the roof.

Not a chance. hehehe

B - Truspeed is the brand Christo sells as well, so when I do get one - he'll be the source. Instructions on his website look straight forward, but how easy is it for a dip s*** w/o the electrical manual? I can strip wires easily enough and use butt connectors - no soldering gun here.

I really would prefer an accurate speedo and odometer. Anal retentative accountant in me.

And no Dan, I'm not getting the electrical manual just yet.

 

[landtank]

Not that I expect Christo to admit to this but that install setup is MINE . It cuts into the harness behind the clove box. It is a little tight back there but it can be done with good results. I basically tapped into ground and 12v on the plug by soldering the Truespeed harness to it. I personally don't like Butt connectors especially when tapping into something that is connected to some sort of Computer module. If thge connector loosens up and some spiking might be a problem. The Video signal from the speed sensor gets cut in half and then spliced to the two lines from the modulator. Using the supplied velcro I stuck my unit on top of the heater core. There is just enough room up there and I haven't had any issues of it coming loose. I did make a jumper incase the module let go I could get my speedo back, wrong but at least something to look at and CC would work.

Another point for having the switch for a second calibration is for mileage reimbursment


My boss is now on this forum now

 

[e9999]

uh, didn't realize this speedo was electronic...
too old I guess, I assume all speedos are mechanical...

[Brentbba]

Rick - too bad you are in Boston (no - not because of the Red Sox - I'd personally like to see them kick the out of those Yankees).

I'd offer you a to help another cruiser owner do this. I don't own a soldering gun. I'm good with splicing, but all I've ever used is the butt connectors.

 

[acf]

So with bigger tires, speedo display is slower than actual and actual mileage is less than odometer reading?

 

[Brentbba]

Speedo is definitely slower based on my simple GPS test.

I think, however, that the odometer will register less miles than actually traveled if I've got this correct. You are now going faster than being recorded, therefore, traveling more miles than being recorded - right?
