PennSilverTaco's "Perfect 5-Lug Regular Cab" Build, Aspergers, and General BS MegaThread!

These twatwaffles still haven't responded to me, even on Instagram!

 

I am currently at almost 101,600 miles. The oil was changed at a little past 99K, and all other fluids have been replaced in the last 10K miles. The owner's booklet calls for replacing the spark plugs at 120K. Should I replace them sooner?

 

tire size?

 

Factory was 215/70R15. I'm running 225/70R15 Cooper Discover AT/3s on the factory wheels...

 

Yes. Yes and yes. How long can they last isnt the question you should be asking. It’s are they performing at the same level as when new. In your case the answer is no way. Plugs are cheap and (relatively) easy to change. No reason not to do it. Plus, the longer you between changes the larger the chance that you seize the threads.

 

What brand should I get?

 

OEM Denso plugs. No reason to run anything else.

 

whats the difference in weight of the AT3 tires and what it came with stock?

 

I have no idea, about for years I ran 235s with aftermarket 16-inch wheels and didn't notice a huge difference.

 

increased tire weight increases rolling resistance which will decrease the performance and MPGs especially in the 2.7l engine, my guess is the AT3 tires weigh a lot more than the stock All season tires it came with

 

True!!

 

at 120k miles as rec'd by the owners manual, they should be an Iridium plug

 

Doesn't seem to be a decrease in performance...

Maybe I should go with Cooper Cobras next time around?

 

My 4.0 v6 had 3 ngk and 3 denso.

I asked on here and people said that was stock from factor.

 

I’m betting all the idle time. I watch my trip fuel economy with a Scangauge, and sitting around idling hurts a fair bit.

 

best MPGS would be stock size at the same weight or less than the factory rubber that came with the truck

 

Sounds about par for the course, maybe even a little better.

 

I believe the Cooper Cobras were the same size...

Also, why was mileage seemingly better with the 235 Michelins?

 

You mean my current figures?

Also, do you have a square body K5?!?!

 

Thanks Lil Yachty!!!!!
