With a little negative camber, how does tire pressure affect tire wear?

I have 15" steelies on my 91 crx si with kumho 711's dropped with Ksports. The front has a little negative camber. Rear is pretty much at 0. Normally I keep the tires inflated to 28psi per the glovebox suggestions. I was wondering if I should keep it lower to have the contact patch all the way across the tire, or increase the pressure? I want even wear with the most traction. As in, not a lot of center tire wear or inner wear. I realize there will be more wear on the inside with teh negative camber.

TIA!

 

first of all, you need to make sure the TOE is properly aligned, not the camber, to prevent uneven tire wear.

yes, TOE is the reason for tire wear, not camber.

you have the right thinking about the tire pressures affecting the contact patch tho. but ive found that its ok, and sometimes better to keep the tire pressures up a bit more than 28psi for better grip. it all depends on the tire. too low and you get a lot of sidewall flex and rolling over. and its usually not the same front and back when im done tuning. honestly, i keep my street tires more around 32psi. for some particular tires ive had, i had to keep the pressure new 40psi to keep it from squeeling.

but in general, for the street, i wouldnt worry too much. around 30psi is fine. autocross and track days, youll notice a difference in pressure changes which matter, and its a useful tuning tool, especially since its free.

but let me reiterate, make sure you get an alignment if youve changed your ride height.

 

I know toe has a huge effect on inner/outer tire waer. But when most of the weight of the front is on the inside of the tire, does that not effect the tire wear as well? I did get an alignment after I installed the Ksports btw. Thanks for your input!

 

with a 15" tire, the sidewall will flex more than enough that the weight is evenly distributed enough that it really doesnt matter.

what will wear more quite frankly is the OUTSIDE of the tire because of turning anyway, if youre into that kinda thing.

 

Whats the point in buying a coilover suspension if you arent going to use it I love the way the ksports improved my ride/handling.
