245/75R16 General Grabber AT 2 Tire Pressure Recommendations?

Max psi with a ratio of no less than 10-15% lower. Soften shocks. You have a good deal of stiff side wall, that will not give you much play or flex.

Call general. Most companies are more than willing to help you get your vx setup properly. If you get your tires s at the right pressure they will last you longer and you will buy again.

You should be nowhere close to 80psi. You guys telling him otherwise are dead wrong.

Your tire pressure is a function of load range, contact patch and vehicle weight. Over inflating your tires will help gas mileage some, but at the cost of traction and teeadwear. There is an ideal range that maximizes youre contact patch and keeps the sidewall from bulging. This is what you should find by doing the chalk test and visual inspection. My 285/60/18s have a load range of 116. I got a chart from the manufacturer with the tires load capacities at different psi and found one that was 1/4 of the vx loaded weight (i estimated about 5k total lbs for towing and hauling cargo). My pressure shoyld be around 28 psi based on that chart.obviously this seems low and I wsnt crazy about it but calculations dont lie.

I put my tires at 28 and they looked good and rode well. I eventually chalk tested higher and higher psi until I found a sweet spot of pressure and wear. It was around 36 psi.

Hello!

I just bought the 245/75r16 General Grabbers At2 today, i wanted to know what was the final result for this topic. I set them up at 40 psi for now.

thanks.

sorry about my english, I live in Guadalajara, Mx

I see the topic and I am like.... huh? Just seems so weird having 255/35s on my STi and 285/60s on my VX. Don't remember how long it's been since I had some skinny cowboys on some wheels, heh.

After doing the chalk test weekly over a month period, I settled on 46 psi. They performed flawlessly during the (few) snow falls that we had this winter. I monitor my pressure and temperature on with my Orange brand tps I mounted in an extra, altered, ashtray.
