Ready... Fire... Aim!

[BobWBristolRI]

After 81 pages of 2,000+ wheel and tire threads (ugh), bought a set of 5 Goodyear Wrangler AT Adventure (LT 275/70/18s Load Range E). Why? Reviews only 'slightly' lagged KO2s in most categories, and I could afford them (hundreds cheaper than KO2s - 5 mounted, balanced, aligned).

RESULT - At 39 PSI, ride was smooth, quiet, nicely a little stiffer, but not much. Very happy with result.

Only issue: The LT275/70/18 spare didn't fit 'happily' on the spare tire carrier. Had to be spare washer 'shimmed' to get it to fit. Done, but I didn't see this in any of the threads about 'mild' upsizing of tires from stock with stock wheels.

QUESTION: Should I really worry about LT Load Range E tire sidewall heat by running 35-39 PSI for comfortable driving? After reading an eye-bleeding amount of forum threads, it would appear to a noob like me that my jeep isn't heavy enough to really cause an overloaded Load Range E sidewall heat issue (until the fall when I'm smuggling those gold bars out of the Superstitions - more updates and mods to prepare for that).

Happy with the result (so far) - the ride quality and the balanced look (not too much, just enough - for now). Curious and interested in observations, insights, and simply loud burps/farts/guffaws. Regards, Bob W, Bristol RI

I like the look. Good choice.

Glad to hear you're pleased with the new rubber, Bob. Thank you for sharing!

Why 39 when door jam asks for 36? Especially with a load range E.

Why 39 when door jam asks for 36? Especially with a load range E.

From my limited understanding (experts please weigh in here...) although the factory stock tire would be 36 PSI, these new LT (light truck) 275/70R18s have a much stronger sidewall, and are made for supporting upwards of 7-8,000 lbs ( Load Range E).

The reason that I opted for the LTs was sidewall strength for any off road driving, as P (passenger) tires are far more prone to sidewall punctures. The problem is (as I understand it) that these LT tires often carry a PSI of 60-70-80 PSI, but that makes them rock hard, bouncy, and not the cushiest ride for a (mostly) streeted Jeep. Granted, didn't need Load Range E (C would do), but that's what was available.

What I've been trying to ascertain (unsuccessfully so far, to date), is what is the best/optimal LOWER (tradeoff) tire pressure to run - that doesn't compromise wear or safety. The Goodyear guys were okay with 39 PSI, but were reluctant to go 35 PSI when they mounted this tire set.

Apparently, (and I'm guessing that it's really meant for much heavier, loaded work trucks) that running these LTs low (35-39 PSI) with a heavy load can dangerously overheat the sidewalls, and potentially cause a tire to fail. That is what I think the Goodyear folks were reacting to.

What I question (and don't know) is... am I perfectly fine to run these LTs at 35-39 PSI in my 4,300 lb JLU Sahara? My gut says yes, but again - not an expert. Also, I'm not familiar with the 'chalk' test that I keep seeing snippets about. Any/all insights appreciated (adding to the 2K plus wheel & tire threads for the next poor noob like me to read, eh?)

I run my E-rated Patagonias at 30 and have been fine at that pressure. I up them to 35psi if I'm just doing a long hwy road trip to get a bit better mpg.
I think I'd go down to around 32 and see how you like it.

Nice looking setup there!
