Lets say I run 35/33 PSI cold, with 205-50-15 S-03

How much lower can I drop the tire pressure and still be withing safe specs and not put uneven wear on tires.
Thanks in advance

 

why?

 

yeah, why? 32 cold is good.

 

i prefer to keep higher tire pressure in front for street. side door says 33psi for rear.. so my front would have to be at 35psi.. i get better traction when front tires dropped.. but then i end up even or higher at the rear..

lets say i'd like to drop fronts to 31-32psi cold and 2-4psi lower on rears...

Sounds like he wants to drag on the street.

 

I'm running 26lbs on my s03's cause i'm too damn lazy to stop and fill them up

 

this is for normal street driving.. mostly for highway.. i noticed less vibration from tires with lower psi at the rear and all the way around..

what got me thinking about it:
i had rotated/balanced tires, didn't adjust pressure, it was cooler the next day

as I pulled on the highway, i noticed no vibration in steering, where i'd still get very mild shake. I checked pressure and it was 35F/30R. While it worked for high speeds, it worked better with 2psi difference (35F/33R) when driving on street.. like more stable around turns.

(none of what I mentioned above is dramatic difference, but if you pay attention to the car.. it will matter)

tirerack suggested 32F/30R if I don't want to screw up tirewear, and no lower than 27 to be somewhat safe..
So I'll start with 32F/30R, and maybe end up at 33F/31R.

 

Don't use low tire pressures. The tires will overheat and your handling will suck - do you want unpredicatable handling if you have to do an emergency manoevre to avoid an accident? I think not.

Get solid motor mounts instead - this will eliminate wheel hop. If you want more traction - get Z10 traction bars.

You drive a FWD vehicle which unweights the front of the car during hard acceleration. Changing front tires pressures is the wrong way to get around this problem.

 

Which would be more beneficial to get first? And how much does each cost? Anyone?

i agree with what you say.. my main concern is road feel.. i lower tire pressure for wheel hop or run drag radials... but thats not in daily driving.. i guess i can't have it all in one... just trying to find out whats the lowest I can run and be safe and without putting more wear.

one thing i don't understand is how would low tire pressure cause tires to overheat?

 

I still have my dunlop SP5000's at 28 psi in the front, too lazy too fill them up

 

I have s03's...what is the correct psi for the front and rear for regular daily driving? Thanks

 

i placed 25Kmiles with even wear running 33-39psi... all of that should be within the safe range... as they wear... they vibrate more at high speeds.. so i was trying to see how low i can go and still be safe.. maybe improve road feel

I run 35-40 psi all around (currently 38) on my all seasons. Why, cause they have next to nothing for side wall strength.

 

The traction bars would be easier to install.

 

traction bars suck, i run around ~28 lbsin my azeins on street! eric
