Re: Are 31's too small for 4.10's??

The OP says AW4.
I'd run 4.10's with my AW4 in a second if I could afford the swap right now!
Some might suggest 34's might be a bit big for 4.10's but it depends mostly
on what you're into. If he finds 4.10 to low for 31's, run a 32x9.5 for the
winter but I'd suggest trying them this winter before he sells them.

Re: Are 31's too small for 4.10's??

Hi Jeff,

The formula to compute rpm with tire diameter in inches and speed in
km/h is:

rpm = ( ratio * kmh * 209 ) / diameter

Your pal's Aisin-Warner auto trans has a 0.75 overdrive.

At 110km/h, assuming his 31's are actually 30.5", he should be seeing
around 2000 rpm with his 3.55 diff. A change to 4.10 would give 2300 rpm
at 110 km/h - much better.

What does he have for a transfer case? NP231? Unless he has a 4:1 low
range conversion, the AW4's 2.80 1st gear would really suck when
climbing rocks with 4.10s and the 34 inch swampers. Better to regear
with 4.56 or 4.88, sell the 31s, and buy a set of taller street tires
with a narrow contact patch and a decent snow tread: 33x9.50R15 BFG AT/KO.
