I just got my Falken GRB's mounted today on the stock rim....I LOVE THEM SO MUCH BETER THAN STOCK!!! A little more noisy but well worth the grip!!! The place that put them on put em at 32psi. I was wondering what I should have it set at...and that is when the tires are cold right? If I check and the tires are cold and it reads 32 and I drive to the air pump and it reads 33psi ...and add 1 psi...will the cold temp then be 33psi?

Thanks every one!!

 

1. You should see if you can get a hold of an engineer and ask one or two of them (two calls is a great test!).


2. The pressure you measure at should be DEAD COLD (as in move the car a few feet). The "cold pressure" will need to be changed with changing temps. It wouldn't hurt to measure the tires (one or more times) with your car at home (dead cold) and then after a few blocks to a few miles. I was really surprised to see how much the pressure in the Toyos would rise over a short, easy run...

3. Keep an eye on the tire wear. You can use a penny or whatever is handy (they even make some inexpensive dial calipers with a "depth gauge" built in -- measure the depth of the tread from the middle of the tire to the inside and/or outside.

Comment: some of the tire pressure recommendations for a given tire have been all over the place (as reported by members here).

 

BTW, glad your enjoying them!

Feel free to experiment with some pressures above what you are using (33/33), (34,34), (35,35), (34/32), (35/35), and so on...

The front-to-rear will alter the oversteer /understeer (front/rear balance) and the change in pressure will alter the ride and handling (depends on the tire)...
