i am running Goodyear GS D3s on 17" S-Lites and use my car as a very spirited daily driver. i am curious what tire pressure some of my peers are running on the same? thanks for your input / advice.

 

mine are 16's but run 34psi in the summer time.

 

i failed to mention i have 38 psi as of last night and i am trying to determine if i am on the very high end of the range.

 

yes, you are on the higher end but ive seen people use over 40psi
for autox. for street i found that 38 is too high and makes the tires
hop too much, plus the ride is too firm. but that's just me.

 

I run 34 PSI on the street. At the track and autox, I run 40/38 PSI cold.

 

Tire pressure is largely a function of how many people there are in your car for street use.

Different story on the track where you can adjust pressures for track or driving conditions.

For any tire used on a MINI for street driving pressures are always in the same range.

For 2 people use about 33-35 psi cold.
For 4 people use about 36 to 38 psi cold.

38 is higher but still ok, no need to go higher as you will start to wear out the middle tread of your tires.

I would use 36 or 37 psi if you have 2 people.

 

I run 35 psi cold on 16's.

 

35 psi on my GS-D3's 225/40/17. I might bump it up to 38 for this weekends autcross.

 

i use 36psi street and 40/38 psi autoX
on 205/45R16 :-)

 

36psi on 215/45-17
