[86moneypit]

I got a set of 37x14x15 iroks on 15x10 steel bead lock look alikes on a 86 runner. what pressure you guys run on the street to get the best performance on street and wear.

thanks martin

32

[IronClad]

90psi..


Serriously every single truck is different. YOU have to experiment and figure out what the right psi is right for YOUR truck.

[86moneypit [OP]]

yeh i was thinking that just seeing what people run

86 runner with all the crap

[Runar]

Street pressure should always be above 20psi at least, regardless of tire size.
I would guess ~25psi for that tire size for a Runner or simlar size truck

Cheers

anywhere between 25-30psi for the street

85 runner 37x12.5x15 rad iroks 20-25 on street  its a dd.

best thing is pait three stipes across tread and drive a little bit watch the paint wear, you should know what to look for paint missing in middle to much air, piant missing on outsides only not enough air.

thanks for the tip i like useful info like this

[Dr Phat]

32-1/2 PSI

[86moneypit [OP]]

why 32 1/2 psi whats with the 1/2

[Steve_925]

i ran mine at 35 psi with same set up. the more air you put in them the less tire that is touching the asphalt which means less drag and less wear. and when on the trail aired down the tires would wear on the outside more so they kinda even them out

[86moneypit [OP]]

makes sense thanks i had them at 22 and they feel heavy

[Dr Phat]

Steve, wouldn't that just burn out your centers quicker?

[Steve_925]

Steve, wouldn't that just burn out your centers quicker?

i never noticed the centers wearing more.

[yota_krawler]

3-8psi

works great

[86moneypit [OP]]

on the street

[yota_krawler]

small joke.....

[86moneypit [OP]]

10-4 

[Dr Phat]

Just like my 1/2 PSI lol.

[86moneypit [OP]]

i tried 27 today with some chalk across the tread and it seamed to be pretty good. it steered a little better to.

do you know where i can get a 1/2 psi increments air gage. 

[Dr Phat]

Its in the same aisle as blinker fluid in autozone. Ususally right across from the parts counter where you can pick up exhaust bearings. Hehe.

[86moneypit [OP]]

man i want to go to the autozone by you,mine has all the normal crappy parts.

[blackyoter416]

are they radials or bias ply??
im running my bias plys at around 15 on the street, too high of pressure will burn up the center real quick.
if they are radials id run them at atleast 25 or 30

[86moneypit [OP]]

bias

go to napa and get a 90-379 air gauge low pressure set up
