Hi everyone I need some advice, I have just fitted a new set of BF Goodrich
T/As 235/70/16 to my 2002 Cherokee (Liberty) and I unsure of the tyre
pressures for them. Will they be the same as the Wranglers I have just wore
out, which were 33psi or can any one tell me what they are running in their
BF T/As......... Many thanks

 

Normally if you go up in size, you can drop the air a bit, but only a lb
or two.

You can do a chalk test to see how much rubber you have on the road.
Put a bunch of chalk marks across the tire and drive straight a few feet
and see what is left. A good footprint will have an inch or so at the
sides max.

water tracks work well too. JP or one of those magazines did a pretty
extensive article a couple years ago about tire pressure, and the
comment was made that most vehicles ideally have different pressure in
every tire. Of course, ideally, I'd have an 18 year old redhead
girlfriend that would be rich, but you get the idea.

If the Goodyear Wranglers wore out evenly at 33, then the BFGs should be
fine. Personally, I have to wonder if 33psi is a bit too high for any tires
on that vehicle. If it was in my garage, I'd be thinking that 28 to 30 would
be about right.
