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.

Replying to: toe1 (Jul 30, 2007 9:33 pm) 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.

Replying to: ealexand46 (Dec 10, 2006 4:38 pm) 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?

Replying to: toe1 (Jul 30, 2007 9:33 pm) 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. I’ve 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 didn’t 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 don’t 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 won’t 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 it’s 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. It’s 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. |
