#1 of 39 Chevy Suburban OEM Tires / Wear Problems
May 06, 2007 (6:50 am)
I am trying to find out what were the correct tires to have been originally installed on a 2004 Suburban LS 1500 4x4 with 17" wheels (assembled in Mexico and delivered to North Carolina, if that matters).
I purchased this vehicle new in June 2004, and it currently has 22,000 miles. Twice I have taken it to the dealership because of uneven tire wear and cupping, and have paid for alignments both times and had the tires rotated. With three tires now severely worn, I finally noticed that the vehicle was delivered with mismatched tires. Three tires are Dueler H/Ts (highway tread) and two tires (including the spare) are Dueler A/Ts (on/off road tread). The one A/T on the ground is the only tire not showing uneven wear. All the tires on the ground are 265/70 R17.
From what I have been able to find out, the different tread pattern, with its different rolling resistance and slightly different diameter could have been the cause of the uneven tread wear. I never hit anything or did any off-roading to knock out the alignment, and I always monitored the tire pressure. I have driven probably less than 500 miles in 4-wheel drive.
Any info about what should have been the correct tires that I can bring in to talk to the dealership would be appreciated, along with any other advice or suggestions. I have seen one source site H/Ts as OEM, and another sources sites the Bridgestone catelogue as specifing A/Ts as OEM. Would there be an intentional difference in OEM tires between 2-wheel drives and 4-wheel drives, or between Suburbans and Tahoes?
I know it is odd that I have gone nearly 3 years without noticing the mismatched tires (especially since they are raised white outline tires). The A/T came on the passenger side rear and I approach from the other side at both home and work, and they really don't look that different from the side (although the tread does look very different). I am still a little surprised I did not catch it earlier, but neither did the dealer or assembly plant evidently. Thanks.

I have a 2002 Tahoe 2wd with original
LT 265 R70 16 tires and am ready to buy new ones. I am thinking about 265 75's instead of 70's. I know it will throw the speedometer off 2 or 3 mph but will they ride a little smoother than the 70's. Any info would be appreciated.
#8 of 39 Tire Pressure Sensors
Jan 07, 2007 (5:38 am)
2004 Suburban has factory installed "automatic" tire pressure sensors. I had them all removed with a tire replacement due to a defective one and its high replacement cost (~$70 each).
Idiot light is now constantly illuminated and odometer display reads "check tire pressure". Dealer claims there is no way to remove the annoying reminders. Has anyone had success in eliminating these and suppressing the dashboard reminders?
#9 of 39 Spark Plugs, Tire Sensor Indicator
Jan 10, 2007 (7:15 pm)
I just replaced my spark plugs & spark plug wires on my 04 Tahoe Z71. The ownerís manual and dealer tell you that the stock plugs are good for 100,000 miles. BS, on all 8 of my plugs the tips where a dark brown in color. I had 51,300 miles on stock plugs. They use AC Delco spark plugs, which were obviously bad. I replaced them with the E3 spark plugs. I bought the new E3 spark plugs at Kragons for $5.99 each; this is less than half the price most places are charging for the Denso Iridium plugs. The E3 plugs are a 3-prong plug in which all the prongs are attached together at the top. They look very cool and are suppose to give a lot better and hotter ignition burn of the fuel. By the way, my Tahoe was running great prior to me changing out the plugs and wires. You can not tell by the way it runs or the mpg it gets if the spark plugs need to be changed. On my last tank of gas I got 18.2 mpg with the bad plugs & plug wires. I suggest that the plugs be inspected at a very least at 50,000 miles if not sooner. 100,000 miles is way too many miles. They were all easy to get to except the one in the back on the passenger side. There wasn't much room to get a socket in there. Also there is a heat shield around each spark plug. The spark plug wires go through the end of the heat shields and attach to the spark plug. There is a spring on the inside of each heat shield. You can not see the spring until you pull the spark plug wire off the spark plug. This is very hard to do because of the tension between the spring and spark plug. You will need at a very minimum a pair of Channel lock pliers or pliers to pull the spark plug wires off of the spark plugs. It is amazingly hard to get the spark plug wires off of the spark plug.
I also replaced my spark plug wires with MSD 8.5MM Super Conductor Spark Plug Wires. They are a lot better than the stock plug wires and only cost $64.95 for the set performanceproduct.com. I recommend these plug wires or if you could afford to put out $283.00 plus S&H & Taxes then buy the Nology Hotwire spark plug wire set. Don't wait until 100,000 miles to change out your plugs and 150,000 to change your plug wires. You will be happy you did it. In addition, you will not need to put the heat shields with the springs inside them back on when you use either of these spark plug wires. Iíve read from a previous post that someone said the springs where caring some of the spark from the coil through them, and grounding out on the heads causing a little loss of power and mpg. He said you could see this at nighttime. I didnít check it out prior to changing my spark plug wires but it does make since that they would by the way they are installed. So this is good information about taking these springs off. They are not visual do to they are inside the heatshield. I recommend that if you buy a better spark plug wire set then just donít put the heat shields with then springs in them back on. I guess you could try and remove the springs from the shield also. But by the time you get the shields off using a pair of pliers you wonít want to put them back on, believe me.
To the person who has his tires air sensor light that comes on and stays on, this means that one of your tires has below the recommended tire pressure. I have 45psi in mine. I run 305 70R16. I just changed my tire pressure to 45psi. At 45psi compared to 35psi I get approximately 2 more mpg and my Tahoe rides a lot smoother. If your tire pressure drops below I believe itís 28-psi the indicator light and your DIC will let you know. My sensors work great and have let me know in the past when one of my tires had a slow leak and the tire pressure dropped. I have an air pump I plug into the lighter, which works great for pumping up the tires. I bought it at Wal-Mart for around $10.00. Itís small and also has a light on it so you can see at night if you need to. I keep it in the back of my Tahoe and recommend this to everyone.
