Tire Pressure recommendation

[sparkyblue]

Awesome thread, haven't seen many running the Falken Windpeaks so I'd like to request RCTIP for:

2010 LX570 on Falken Windpeak AT/3W E RATED LT285/65/18

Currently running 35 cold F/R and they get up to 38 when hot.

The Recommended Cold Tire Inflation Pressure (RCTIP) for those LT285/65R18 E 125/122S tires on your 2010 LX570 is 37psi Front/Rear.

Sorry, Nitto doesn't make an ISO Metric Ridge Grappler in that size - please check the tire sidewall and ask again.

Hey @gaijin wanted to request pressure for:

General Grabber ATx 275/60/20 119/116S

Thank you!

Sorry, the General Grabber A/TX doesn't come in an ISO Metric size 275/60R20. Please check the tire sidewall and ask again.

Also, I'll need to know whether you are using these on a LC200 or LX570.

Hi @gaijin thanks for doing these.

RCTIP Request for the following:

Michelin Defender LTX M/S and Cooper AT3 4S - both in a 275/60R20 set up on an LX570.

RCTIP Request for the following:

Michelin Defender LTX M/S and Cooper AT3 4S - both in a 275/60R20 set up on an LX570.

For ISO Metric sizes I need to know whether the tire is SL (Standard Load) or XL (Extra Load/Reinforced), and also the Load Index / Service Description e.g. 116, etc.

Please specify whether SL or XL for each of these tires, and also the Load Index for each.

SL 115 T for both (in case you need the speed rating, too)

Maybe this belongs in the SQOD thread. Sorry for the drift. I understand how to get to the recommended pressure for road use based on load limit (ie 43psi for my KO2). And I understand conceptually the benefit of airing down for off road and sand. I’ve seen pics of bead locked tires down to 5 psi. And understand that lower pressure suggests lower speeds.

What I don’t understand is why it’s okay to do so without damaging the side wall. It seems like extended periods of time is spent at low psi when off road. And considerable flexing of the side wall.


Why is it then safe to just air up before hitting the pavement again? Are tires designed to be subject to that flexing as long as they don’t get overheated (with speed)? Or is there some degradation (side wall weakening) and one should expect to replace tires sooner than if they weren’t subject to off road use?
