Dakowner, no one need apologize for discussing any normal technical concern. No one can take a munfacturer's posted mileage rating at face value, any more then you can take the salesman's word on maintanence issues. The best way to assess mileage is to discuss it with a group of users. Some of us, like myself, are here to research a vehicle they might buy in the near future, so it's not quite the case that "we all know what we were getting into" - some of us want to know before getting in, thank you. Greggpats, it's nice that gas cost is irrelevant to you, but it's of interest to some. If your major concern is acceleration, well, good for you. That's boring for me. If my driving were the 10K/year you use as an example, I'd be less interested in MPG myself, but that's a low figure, and I'm not willing to assume that $1.75/gallon is normal any more.
#1879 of 1886 Bigger tires, what effect?
Sep 26, 2003 (10:06 am)
Have been shopping for tires for a couple of weeks. Original tires Goodyear Wrangler, 265/70x16 with 77,000. Wanted Bridgestone AT Revo's, but not available 'til Nov. Decided on Yokohoma HT-S Geolanders. Same size not available without a wait also, so have ordered 275/70x16s. Tire is about 1/2" taller overall. I know it changes over effective gear-ration by small amount, but will this effect computer parameters? Will it need to be flashed(i.e. by dealer) or is this small enough of change that computer will compensate? Any thoughts on this will be appreciated! Jim

This is a safety concern.
The factory service manual warns that the ABS can be affected if the overall diameter of the tires is changed from factory-delivered.
Additionaly, if you run an automatic tranny, the speed sensors that control shifting may be affected. (do not forget that there are sensors at the INPUT and OUTPUT of the tranny that feed into a computer to control shift-points, shift-length and overall shift-quality.)
There is also a sensor in the rear axle housing that feeds tire RPM to the onboard computers. These computers need to know the tire rating in "rotations per mile" entered into the computer. ALl calculations are based on this pre-programmed setting.
Either pay the dealer to update the onboard computer or use one of those "programmer boxes" to change it yourself.

I agree with Bpeebles. One thing I would add is that with respect to an automatic transmission, it should eventually readjust the shifts points on its own as it goes through the learn cycle a few times.

the truck is a Sierra 1500HD,2wd,4 spd auto trans,300 horse V8,leather,Onstar,XM sat radio,electric seats and mirrors,regular on road tires,3.73 rear end, locking rear dif,6 disc ,bose stereo am/fm,...anyway lots of bell and whistles..compared to my sparten quad cab.
By the way,if any of you guys want the Fit Kit made by Thule for the 00 Quadcab let me know and I will let it go for $10.00 plus shipping.
Tire talk, I replaced my factory rubber with the Dayton timberline highway series and when i sold the truck they had 31,000 miles on them and had plenty of tread left.
all for now,

I finally got the leftovers from my Quad Cab sold on Ebay. Got the Leer topper sold locally and my spare set if tires with the Blizzak snow tires shipped off today to spend the winter on a Dakota R/T that lives in New York. I've still got the brand new spare tire from my Quad (15x8 with the 255 65/15 Eagle LS) that has been sitting in my garage since my truck was new. I forgot I had a cruddy tire and rim from my 93 on it as a spare when I traded for Monster Quad. Guess that will go to Ebay too! How did people get rid of their extra things before online auctions?
Monster Quad is fast approaching 6,000 miles with no problems other than a lazy headlight. The drivers side lo/hi beam does not turn on on the first time. Turn it off and back on or flash the high beams and it turns on and works till the next morning/evening. I put some of those Xenon headlight bulbs in and those might be part of the problem. I upgraded the factory radio with another factory radio. I found a kind of rare radio with the code RBU. What makes this different is it will work with headphones as well as play through the speakers. My daughters have questionable taste in music and being a nice Dad I usual let them listen to their "music". The RBU radio has a headphone switch on the faceplate. When you press that the radio turns off the rear speakers and you listen to whatever you had selected thru the front speakers. For example say I was listening to an FM radio station. That would make available to the back seat passengers the cassette tape or CD player part of the radio. They pop in their CD and with an infrared remote control select the tracks they want and listen on their wireless headphones (also from Ebay, came from a Chrysler Pacifica) The CD player (or tape) plays independent of the FM portion of the radio and everyone gets to enjoy their music. My only question is why didn't they have these things 15 years ago. I really would have enjoyed those family vacations. My next step is to hook up a 6CD changer or satellite radio so the rear seat passengers or myself have additional choices. As long as I stay with the Mopar parts everything is still controlled by the rear seat remote control independent of the front seat passengers music choice. Rick

Stephen, your trucks sounds really cool. 300 horses should move you along quite smartly. Enjoy!

Rick, any sound system that would allow listening to a ball game while the kids are "twisting and turning" in the back seat, can't be bad. Happy to hear that you sold the stuff that was now surplus to your needs.
