What is the OEM spare tire size and brand?


Recommended Posts

Posted

Well some of you know I had my spare tire stolen off my truck a few weeks back. I finally got my replacement spare wheel and the spare tire hoist. So all that is left is to get a new tire mounted on the wheel.

 

Can anyone tell me what the spare tire size is? I'm thinking its probably 265/70r17 since thats pretty close to the 275/55r20's overall diameter, which is what the rest of my tires is.

Also, can anyone tell me the spare tire brand? More for curiosity sake. I will likely go with the least expensive tire possible, but if the OEM tire is a close second in price, I will go with that.

 

Thank all

Goodyear, 285/70/17

 

That's nearly a 33" tire.... I don't think that is the correct size.

Unless GM is doing something different these days, the OE spare is always the same size and brand as the rest, the only difference is they use a cheaper steel wheel. I believe Good Year is the current OE tire and is what your truck likely came with, however checking on my end there is a plethora of brands available in 275/55R20, so you could just go with the cheapest you can find for the spare which is likely to hang under your truck unused and collecting dust anyways, so no reason to spend big money on it.

Do you have 22's on your 4 corners?

Yea, I bought a new spare wheel, but I will get a cheap tire for it. I know it wont ever get used, but better safe than sorry.

my exhaust looks like crap for a 12 day old truck.

Hope that is mud and not rust.

No, factory 18's. 265/65/18 goodyear white letters.

Base Z71 wheels and tires.

 

Yes, I notice the spare is larger then the factory wheels and tires.

I didn't put any of them on there. Have to ask GM why.

Hmm. thats interesting. Well. I guess I'll see whats the better deal at the tire shop.

wonder why I got a 285. Seems to big to me. I'm glad it is the same size as my new tires.

But why? 265/70/17 would have been same as what is on my truck.

 

I'm also a 1/2 ton 4x4 Regular Cab. Not a 2500 or anything like that.

Ok... I just went out there and washed the tire. I wanted to know for sure.

It is a 265/70/17. Even that picture looks like a 285. Weird illusion or something.

lol, no worries. The picture does indeed look like 285. Thanks for checking further.

 

 

100% sure Goodyear Wrangler HP, p265/70/17.

 

Thanks. I had a hunch. Much appreciated.

    • That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
