Tire pressures
 

I put Ford Racing “C” springs and Steeda billet aluminum C/C kit in the Mach last weekend. I took it to the local alignment shop today to get it all straight. They only do alignments and are the specialists for lowered cars or lifted trucks. After the technician told me he could not align the car, bad Steeda X2 ball joint, he said he inflated my tires to the tire manufacture max pressures. I have Sumitomo 245/45-17s in front and 315/35-17s in the rear. I have run for the past two years the Ford recommend 30 PSI all the way around.

What is the correct PSI to run for a DD?

i run 16 psi all the time in my car(rear), i have 315 bfg drag radials.

Re: Tire pressures
 

for street tires the proper pressure will vary since the proper pressure is really what give you a nice even wear across the tread of the tire. for me it was 38 in the front and 44 in the rear with 265/38/18 and 315/30/18.

Mine is a dd with the same size tires, I run 32 psi on all 4's.

275/35 295/35 18 cold pressure i run 32-34 front 28-30 rear.

I will adjust my pressure some what depending on the time of year.

Re: Tire pressures
 

i would just run what ever the tire says its suppose to be, your going to diff answer cuz not everyone is running the same tire you are
i've always done what the tire said on psi and its always been fine for me
