I didn't even think about weight distribution but I think you're right, good point. You could scale the car and adjust and use the formula to find the psi for F & R seperately by only multipling by 2 in the first step and dividing the GVW by the percentage of weight on the F vs. R, basically seperating the calculations to find the max. for the front and rear based on the weight distribution of your vehicle.

I'm still confused. The max tire pressure is.. the maximum pressure.. If it says the max is say 50psi, and you measure your cold tire pressure (I believe the 'max pressure' rating is cold pressure) and it's 50psi.. that's 50psi. Why would really any math need to be done?

I guess because your car burdens your tires with less than their maximum load rating?

Forgot about the load rating being in there.. my tires load rating is like 850 per tire.. maybe higher but I know it's under 900. I should be careful loading up the car and hauling with it :P

is it just me, or those 19 inch wheels look like they have the wrong offset, looks like a 35 offset to me which sticks out to much. Lowering it would cause major problems.

thanks!

back on topic:

let us know how you go if you do decide to lower it. will be interesting to see the result!

Looks good. Whats the offset?
