For this you have to know some more.

From the tyre 1 . maximum load or load-index 195/50/R15 88V would mean
loadindex 88 stands for 560 kg/1235lbs and V means tyres to be used up to 240km/h.
2. Pressure at wich the maximum load is wore up to reference speed of mostly 160km/h / 99miles/h.
This is for normal car tyres 36 psi/2,5 bar and for reinforced tyres/XL/Extra load 2,9 bar /42 psi.
The maximum pressure of the tyre of mostly 3 to 3,5 bar is not important.

From the car :1. the Gross axle weight ratings front and behind or if you evert weighed it the weights on the seperate wheels. Can be foun in Europe on a metalish plate under the motorhood or in one of the doorstyles.
2: The maximum technical speed of the car , or the speed you sertainly wont go over in practice.

This you can fill in in spreadsheet I made, in wich I use the equation,the European car- and Tyre-manufacturers also use , and wich is the savest in the world up to now, but I already found a better system on the internet.

In the newest version I chanched the power used in the equation to an even saver one for more savety.
If you cant figure it out, give me as much details as possible, and I will do it for you.
