So I'm sure that this topic has been talked about already, but I haven't been able to find it.

 

I have a 2009 Silverado 4WD with the the RC 2'' leveling kit, and a 1'' block kit in the rear. I also have the GM mud flaps on both front and back. Stock 18'x8' wheels with the stock 265 65 18 tires.

 

I am going to put on a set of Cooper AT3's or BF Goodrich All Terrain's and want to go up to either 275 65 18's, or 285 65 18's. Although the price for the 285's is significantly more, I would like to put them on.

 

My concern is if they will fit or not. The mudflaps do take up a little bit of space on the inside of the wheel well, and I dont want to rip them off with the bigger tires. Any idea how noticable the difference in size would be between the 275's and 285's with the naked eye?

 

If anyone knows for sure, or has experience with this same set-up, please let me know. Any pictures with the same set up?? It's too late to take $1,200-$1,300 worth of tires off and get money back if I see they rub! Thanks.

To the naked eye will be on an individual basis, but I dont think it would be much if at all.

Yeah I typed that wrong. I meant to say 275 70's as the other option. Anyone else have that exact setup? Have you guys seen those tires fit in person, or is it just your opinion? Thanks for the comments. When I figure which ones I'm going with, I'll get them put on a take pics. Anyone have advice on Cooper AT3's or the BFGoodrich All-terrains? Opinions?

I've seen both sizes actually fit in person, on a 1500 with a level kit. As far as BFG vs Cooper....I've had great luck with BFG's. I haven't tried the coopers yet, but I've heard great things about the AT3's. I really think either one is a great choice.

I also forgot to ask. Where can I get my truck re-programmed for the bigger tires? I would like to keep my speedo and odometer accurate. Is that something I can do myself, or go to a dealer...or?

You will need a tuner to change those. You can go with any handheld that has that option, or my favorite..... Blackbear Performance. Its all controlled electronically.

What sizes will be offered in the C load rating?

 

 

The 275/70/17 and 275/65/18 are offered in a Load E or Load C rating. Those are the only two I know of. There are also other sizes in P-rated...but they have fewer sidewall plies and shorter tread depth.

The 285's will be just fine....and look great...but they're pricey! The 275/70/18 is another option as well

      HighMileage oils or stay with Dexos 1 ?

      By Z45 · Posted

      dexos began as an effort for GM to control the oil change market because the Quick Lube Industry was eating into dealer service department profits big time. So they attempted to get other oem’s to develop standards as well and that would make it hard for Quick Lubes to compete because all the oems would be different. GM faced lot of industry push-back, mostly the quick-lube industry and they went to licenses. Still GM it making a ton of money (est'd 30-40 million in 2025) off the license structure as they charge a hefty fee to get oil tested then require a royalty on ALL gallons sold applicable to GM vehicles.

      Those are parts changers. It can get expensive though. I was a mechanic for 30 yrs. My truck has made this noise since new. I really don`t know what it is. It really doesn`t bother me. I`m still in warranty but have not brought it to the dealer.   I`m not buying the oil pump prime thing. Screw the TSB. I believe it`s in the trans pump gears. They rattle when that piss poor ULV oil drains off after a while. I believe those sharp tooth gears, with backlash, can rattle when dry. Not a vane style oil pump. Wonder who`s right? Me, or the TSB?🤔   Maybe I`m wrong?

      On the PCM side, blue PCM connector, pin 18, solid gray color (no stripe) wire circuit 435.  That is the EGR low circuit which an issue on that line (be it the wiring, the PCM or the EGR valve or system performance) will trigger P0401 when it tests that code.     There is also a VERY old TSB that states to make sure you clear the DTCs ANY time the PCM is unplugged, reprogrammed, or if the EGR valve is unplugged or replaced as the PCM has an auto zero function in the PCM for the EGR pintle data   61-65-59: SMU - SECTION 6E - ENGINE CONTROLS - CLEAR DTC'S - (Nov 25, 1996)   "CLEAR ANY DTCS FROM THE VCM ANYTIME AFTER DOING VCM REPLACEMENT/ PROGRAMMING, TURNING THE IGNITION ON WHILE THE EGR VALVE IS DISCONNECTED, OR REPLACING THE EGR VALVE."   Some diagnostic aid notes in the GM diag on P0401 for a 1995 S10 Blazer:   Diagnostic Aids Notice: In order to prevent further damage if the EGR valve shows signs of excessive heat, check the exhaust system for blockage (possibly a plugged converter) using the procedure found on the restricted exhaust system check. If the exhaust system is restricted, repair the cause; one of which might be an injector which is open due to one of the following reasons: Stuck Grounded driver circuit Check the oil for possible fuel contamination if a stuck open fuel injector is found. Poor connection or damaged harness - Inspect VCM harness connectors for the following conditions: Backed out terminal BL 18 Improper mating Broken locks Improperly formed or damaged terminal Poor terminal to wire connection Damaged harness Intermittent test - If connections and harness check OK, monitor a digital voltmeter connected between terminal BL 18 and ground while moving related connectors and wiring harness. If the failure is induced, the voltage reading will change.
