Tire PSI question

quick question-
I just got a set of BFG AT2 put on my 17’ crew max.
They are 285/75/17 and pre inflated to 70 all around.
It seems a bit much?
Any input would be greatly appreciated!
Also have the 5100 on the truck set in the middle (level).
Thanks in advance!

 

Way too much. First step call or email BFG and give them your truck info (lift specs, wheel size/offset, tire size, etc.) and they should be able to give you a starting point for PSI go with that monitor and adjust as necessary. I did that with Nitto surely BFG can point you in the right direction.

 

Thanks man.
The max says 80 so I assume it’s not too far off. Maybe 60-65.

 

My Nitto LT275/70/18 are 80 max but Nitto recommended about 38 rear and 36 front. I do 38 all around and am getting good even wear. YouTube the chalk line test to adjust for even wear.

 

Way too much, between that tire pressure and 5100s pre loading the coil springs that truck must ride like the flintstone wagon.

Go down to 40-45 and do the chalk test to fine tune. It'll rude so much better and increase traction, tread wear and tread life.

 

60-65 is likely still way high. Most I’ve calculated for LT tires on a tundra is 55.
What are the specs of the tires that came on the truck originally?

 

Go for a ride. After a half hour or so stop and run your hand over the tread. If its warm in the middle and cooler on the edges, too much air. If its warm on the edges and cool in the middle too little air.

 

I have 43 lbs in the LT tires on mine. Same temp all the way across.

Thanks all.
I’ll give the chalk test a go tomorrow

 

I run 32psi in my 285/75r18s and the middle of the tread is still wearing faster on my Toyos RTs.
