drive tire sidewall has little dry cracking run or not

If it was my operation I would fastrack to the drive tire line that I planned to use as long as my wallet afforded to do so. This would protect wallet in the future from unseen collateral damage in the diffs. from running mismatches.

Your new cap will self destruct under heavy loads. Use it as a spare for temp use or when you get a new set of tires.

If you run the weathered tire, run it at recommended pressure, 105 psi.

A good set of tires is essential, try not to cut corners here if you can so it doesn't cost you more later.

 

I wouldn't hesitate to run it short term, but would strive for a good base set of the same height to avoid other unnecessary issues.

I would be willing to bet that she'll pull better. You'll probably feel like you have a new turbo.

Might be a good idea to drain the bottom off the fuel tanks. After the truck sets overnight the water will settle to the bottom.

 

Are u hauling logs?

 

Hate to be bearer of bad news, but them some old tires. Starting in 2000 they began using 4 code.

Read more here. Go to markings.

If the last digits are only 3 numbers then the tire was manufactured before 2000.

So that means your carcass was built in the 47th week of either 1997 or 1987, My guess would be 97. Either way tire is at least 14 years old!!

 

Log; I am a mech at my father-in-laws pole yard and we run mismatches some. Running poles is much like logs. Trucks with loaders and the bump around of a loader unloading the trailer. I agree with bender though. Keep your mismatches the same. We always measure and put the closest together. Also with the cold weather you will have better luck with them. Also always run stated psi on the sidewall. Mismatching stated pressures on tires will do the same as running to tread depths. We try to always replace in pairs or match the used tires we have. We have a good stockpile though. We see cracks and chunks on drive and trailer tires. Try to use best judgement. Keep cracks and such off steer tires at all costs. Keep new tires off with used if possible. Also you can run that so so tire on the front of a trailer. Try to keep your best on the rear as if they blow back there they will cause more damage than if they were up front. Tearing up lights and such. Good grab though...we got some deals like that last year on a bunch of mounted tires. Ran on trailers for a good while and saved a ton of money.

One more thing..if the filters were that dirty and wet and would do what bender said and drain the bottoms of tanks but also add some lucas or powerservice or some ATF. More than likely you got a bit through to the injectors. A good practice is to fill the filters up with AFT instead of diesel...or Lucas if you can afford it...lol. Each time you change your fuel filters this will give you a little cleaning for a little bit of money....some preventive maintainence.
