What are other members are using on their 20s wheels? I am running 235/30/20 and 275/30/20, running 7 pounds over factory pressure recommendation. 37 in front and 44 in the back. debating should I used more

Tks in advance

 

I am also interested in this... I own a 987 boxster S with 20" techarts and now, after a year and a half with the wheels I cant seem to find on the net any info on the recommended tire pressure for a 20" wheel. Tires are 245/30/20 and 305/25/20.

 

I would start at 38PSI all around and adjust to your preference...44 in the rear sounds a bit high.

 

i was running 44 in the rears and breaking loose alot (Stage II 996tt). Also noticed moderate amount of increased wear in the middle of the tire so lowered to 41 rear, 37 front and very happy

 

Tks for the input, I lower to 39 in front and 42 in rear, so far so good

 

I have been running 37 in the front and 42 in thr rear on my 997 TT with Champions and P2S's

 

There is no real tire pressure for a specific wheel size. It all depends on a combination of tire spec and vehicle weight.
