oh boy ..
this can be as 'bad' as 'what tires to use' ..
or 'which oil' etc.
and ...say you are running these LT's at 38 front, 48 rear.
I like that just fine. Very much so ..and I recommend going by the tire
sticker on the van's door frame.
I adjust tire pressures for handling first, load second.
I think that's what VW had in mind with their tire pressure
recommendation.....best handling.
If carrying a big heavy load ..
sure, add some pressure, and of course never exceed the max pressure
cold, shown on the side of the tire .
other vanagon owners though ..
see their vans as trucks and adjust tire pressure according to load.
I've been driving almost 50 years ..
and I have never thought ..'let's see.....max load on this tire is say
1,720 lbs at 55 psi ..
and I think I have 1,400 lbs on that tire, so I should adjust pressure
to whatever that percentage is of the max tire pressure ..
not how I think I'll tell ya ..
perhaps for tires on a load-carrying utility triailer, but for a rear
wheel drive 2WD vehicle ..I adjust for handling.
Having been a car and motorcycle racer in parts of my life, and always a
performance/handling focused driver, I adjust for best handling ..
which will always be more in the rear, relative to the front, just like
VW says.
I've started many trips with rear tire pressure in the high 40's ..
an hour or so out on the freeway ..things well warmed up ...man that
feels harsh.
so I let some out ...get the rears back down to say mid 40's ...like it
much better.
I run fronts in the mid to upper 30's, rears in the 40's ..just like you
are.
re 'sway' ..
do you mean 'handling like a boat' ?
whole other discussion.
this is getting plenty long already.
just one story..
85 Westy ....and 85 westy's and weekenders are noticeably too high in
the front.
guy says his handles like a boat ..and it does.......terminal understeer
and leaning over in turns.
the way I fix that ..
I get the front down with 'normal springs' ..85 GL front springs are
perfect.
If I can ..
I run dedicated front and rear wheel sizes and tire sizes.
my nicest handling vans run 205/65 R15LT's on the front, 215/65 R15's on
the rear. They don't handle like boats .
you may hear many other opinions ...lol !
