Tire option

[bgenlvtex]

Thanks. I don't have stock tires and couldn't easily find it on the inside of the wheel. The door information suggests that the stock tires/wheel should be set at 37 psi, but that can't be the max inflation for the wheels. There is no max wheel pressure numbers in there. I read somewhere that most wheels have max pressure over 100 psi.

Design burst pressure and maximum operating pressure are certainly different numbers.

I will guarantee that maximum operating pressure of the wheel on that Gladiator is nowhere near 100psi.

Currently have wildpeak a/t at3w
185/70 / R17 load range c
I run them at 45 psi
Says on it max 50 psi
for max load 2755 lbs

I drive a mile of gravel roads at least once daily. I got sick and tired of tires with small tread void because those are the ones that'll pick up gravel and then bomb your paint once you hit pavement again. I have found that tires with wider voids in the outer tread blocks are much nicer to live with. Recently, the Milestar Patagonia M/T and Cooper STT Pro have proven to be great. The Falken A/T3W, BFG KO2, Shitto Terra Crappler, etc. are all really bad about throwing rocks everywhere.

I won't buy any 4x4 tires other than the Cooper STT Pros anymore.

For the OP's purposes, for example, the 34.5" LT295/70R18 Cooper STTs have a max load rating of 4,080 lbs. http://us.coopertire.com/tires/discoverer-stt-pro

Seems like that would be one option that would work for you.

And that type of tire/18" wheel combo would allow you to still retain some off-road capability. since you have a Rubi, it would be a shame to cancel out all of that vehicle's off-road capabilities by putting street tires on it.

The number in the door appears to me to be neither of those. It doesn't say "max" anything; just a recommended tire pressure, I think, at which the GVWR can be achieved.

Yep, I'm not anywhere near my truck.

You will likely have to dig for the information, but I can assure you the installation of an LR E tire, and the air pressure required to obtain the maximum load @ value will exceed the maximum inflation pressure of the wheel.

Okay. Thanks. I crawled under my truck and looked at the matching spare wheel, which mercifully was mounted inside-down.

It says: 5/6H = 60 psi max; 8H = 80 psi max.

What do the references to numbers of Hs mean? Is that the number of bolt holes? If so, why would that matter? I can see number of lugs affecting max load, but that affecting max pressure seems counterintuitive to me.

For what it's worth, the load rating of the OE wheels is "proprietary or not known" but the load rating of the Mopar Gladiator accessory wheels is only 1,950 lbs. which is far less than the tire rating. So, one can't assume that the OE wheels will never be an issue.

That is probably a multi use casting insert that is re-usable. There is no 8 lug design for that wheel.

And look at all that nice void in the Chinesium casting will you?
