what tire pressure are you guys running?? just wonderin

 

34psi

 

even on 555's?! ... i thought all Nittos are suppose to run higher?

 

ive heard the same, but i thought it was only like 2 psi. check your sidewalls

 

lol ... soo howwould i go about checking my sidewalls.. and what am i looking for???

 

how do you guys like your 555s? Im thinking of buying a set. I currently run the Toyos prox 4. Yay or Nay?

 

Put some white shoe polish on your side walls, then race it. If your tires are rolling over onto the sidewall in a turn, the polish will be rubbed off = you need more pressure. If the polish stays on, reduce pressure to increase the contact patch until you know where the limit is.

Or if that's to messy for you, buy a laser thermometer, and check for even tire temperature across the thread after a good thrashing.

 

This is actually a slick and easy way to check rollover. Just two or three equally spaced "stripes" from the shoulder to an inch or two up the sidewall and you know exactly how much tire roll you have.

 

had them and hated them....running toyo T1S's now and much happier

 

Dam! Hated them. If you dont mind me asking, why did you hate them?

 

I have the 555's and I love them. Of course they are not as sticky as the stock Yokes, but I have been very happy with them. They are quiet, wear well, and have a good price. I would recommend them to anyone that does more city/highway driving then track time. Max PSI on 555's is 50. There are better tires out there, but for the money there tought to match.

 

33psi on the fronts and 30psi on the rears (235/45/17). When the tires get hot, they work very well... Nitto Tire is a subsidiary of Toyo Tire

 

are you talking about the 555 Extreme Performance? If so, how's the quality thus far?
