First the truck, 86 22r 2wd sluggomatic (auto), lifted about 4".
OK, here's what I'm thinking about.
#1, 31" (30.5" actuall height) tires with 4.88 gears, 60mph rpm's of 2258,
#2, 32" (31.5" actuall height) tires with 4.88 gears, 60mph rpm's of 2186,
or
#3, 32" (31.5" actuall height) tires with 5.29 gears, 60mph rpm's of 2370.

In any of these senarios, I'm going to use an ARB or similar locker so I can actually have 2 wheels driving when necessary.

Keep in mind, the automatic has an unreasonably high (numerically low) OD ratio of .7 to 1
From the factory, my rpm's at 60mph are only 2064, actually below the suggested power range for a 4cyl.

Thanks for your input!

32 with 4.88 would give you nice performance. I'm not familiar with 22re RPM's but I know my truck turns 2750@65 with 32's and I hae 4.56's.

 

The 22r series tends to run happiest in the 2300-3500 rpm range it seems, or mine does anyway.
Right now I have a 4.10 and 27" tire combo, it's a little better than stock.
I'll be getting a 3rd with 4.37 gears in it next week I think, so I'll have a better comparison to what the 5.29 32" would "feel" like.
Thanks,
Todd

 

5.29 so when you go bigger than 32" you dont have to regear again

p.s. notice i say when, not if

 

Ya, you're right about that one.
It may take a while to save up enough for a long travel lift (taller too), and I'll need to get the spring mounts swapped to the top side when I do that, but when that does happen, it'll be 33's going on there.
Either that, or I'll SAS it.
Haven't decided yet.

just sas it now

 

I'm running 5.29 and 33" right now, I wouldn't want to go any lower but then again I have a manual and I've got a set of 35s on order.


Sounds like you need 5.29.

 

Oh, I'd like to, but 5 things come in conflict:
1. Money
2. Time
3. Space
4. lack of another vehicle to drive, and
5. Money

I gotta move out of the city first, get a second car, then I'll be able to play.
