456's and 33's on a FJ

[kling-on]

ok so i know stock h7815 are 28 tall and my Swampers are 33( well real close)

so ....
33 div 28 = 1.17
3.70 X 1.17= 4.32


so since there are no 432 ... 410 are a o/d and 456 are u/d. would the 456's on road be that bad... i like the sound of the off road peformance but i do drive it to the trail any one have 456's and 33's and how does it drive. for next to nothing more i can have the 456's now ... think i should just shut up and do it ???? or stay with 410... i found both set up in drop outs ready to run and for $200.00 more i can have the 456's and the rest is a trade i already worked out soo swap 4.10 ...swap and $200 456 what would you do


thanks in advance joel

Do you ever plan to upgrade to bigger tires? Or ever plan to get a 5 speed or any other overdrive? Do you ever plan to go with any doubler or gears or something for an underdrive?

My feeling is go with the 4.10s so you can still hit a marginally good highway speed. Then, if anything, go with a doubler later.

want and afford are two different things ...35's are a yes but i got brand new swamper to use up first would love a rockbox with the 4.7 gear set ... but both are a ways off ... cash is tight for me ... the cruiser is just for sunday drives and wheelin and i dont go over 2500 rpms unless i'm passing someone

[7FootYeti]

If you are not really concerned with road performance, you may as well go with the 4.56's. I've got 4.10's and 33's and I'm still geared tall. You can always sell the r&p if you need to go lower anyway at a later time.

or get the 4.10's and give me the 4.56's

well if i want to get someplace fast a Cruiser is not the vehicle to do it in.... but it will go all most anyplace i point it .... just not fast

With the 4.10's and 33's, I can do just over 70 at 3k RPM. If you don't want to travel over 2500k with 456's = slow. Just make sure you use the right lane

70 on the speedo or "real" time 70... cause like that would add 1 mph for every ten so your doing 84 at 70 on the speedo if it real time then 456's at 3k would be 56 mph but speedo would make real time speed be 66 .... and well 60 is ok by me

[7FootYeti]

with my gear ratio and tire size, the speedo is darn close to dead on. I've checked it on the highway. It's off by about 1 or 2 tenths per 10 miles.

1/10 per 10 miles you need to add 1 mph to your speed for every 10 mph you are going

10+1
20+2
30+3
40+4... well you get the idea ..so at 70 your doing 77 i miss typed up there

[kling-on]

ok so thats 67.5 at 3k woth 456 Mmmmm

Wouldn't it be
10 + .1
20 + .2
30 + .3
70 = 70.7

nope that 1/100 of 10 but it would be 1/10 of 1



ie one tenth ..... 1 of 10 or one for every ten



J/K but it is true

[7FootYeti]

But what I stated to begin with is that I'm off 1/10th of a mile in every 10 miles.

Isn't that 1/100th?

So for every 10 miles I travel, my odometer registers 9.9 miles.

:oops: sorry missread you are correct for your statement but not the math you should show off 1/10 for every mile or 1 mile for every 10.... but the math could be off sorry

[yooper]

Actually your odometer is probably off more than that. I have BFG 33" A/T's on my FJ62. My speedometer is off by 11% and my odomoter is off by 17%. This is according to measurements taken with a GPS and by timing the truck using highway mile markers - both methods gave the same answers.

The numbers for your FJ60 should be similar, since the factory tire size compared to the new tire size is about the same, and our speedo's and odo's are both calibrated to the factory tire size.

i don't know why the speedo and odo are off by different amount. Probably all 60-series odo's are a little slow or something.

Get the 4.56 gears - your speedo will be almost right on then and highway travel will still be reasonable.

[Advent Horizon]

Well, if anyone cares, I run 33's and the stock 4.11's in my '40. I get about 17.8mpg on the highway with that arrangement (If I keep it around/below 65). At least, that was the last road trip I checked, when I came up here for school. Engine isn't stressed at all, and I'm plenty low enough for the wheeling you can do on 33's.

62 come with 4.11 60 come with 3.70 so its not the same as for the speedo plus you have a o/d that we dont .. wish i could afford a h55 BLING BLING

The mile marker method is indeed the one I used.

Not at all, I would hope you'd do the same for me

[Cruiser4242]

I run stock 4.10s with 35' tires, and I run about 70-75mph, at around 2700 rpms. I wouldnt want to run the engine faster, and I wouldnt want to go any slower, but thats on california fwys where avg speed is 85 or so. It works out well on the street, but with the 1st gear of the 3 spd. its pretty high. If you have a 420 or something, to get a little bit lower for off road, then I would stay high for gas mileage.

my .02

[muddogbob]

I've got 4.88s and 33s...BFG muds

[dd113]

FWIW: Stock 62 with 4.10s and 33s = 1900rpm @ 80 MPH more or less.

Gotta luv the A440 F!

[gunracer1]

6.72s with a set of 44 is about dead on on the speedo, and 5.13s are just about perfect on the speedo with 38.5s. so i suggest you put some real rubber on that thing and quite screwing around.
