Is a Ferrari that heavy? And if so most cars like these have tires with larg reserves to the GAWR's. Copied this from my post in other...
If you keep same sises as OEM from orher brand, maxload and referencepressure is the same, so recomended pressure on car can be held.
Can make lists for those sises too if you like. Most likely also XL. most ZR low aspect ratio tires are XL. This larger sise expected higher...
Here the pressure/ axleload list For max speed 160kmph/99mph, wich you wont go over for even a minute. Then 90 % used of the loadcapacity,...
Also about rimmwidth for tirewidth and aspect ratio, I did research ETRTO " allows" on 305/30 rimwidth of between 10inch and 11.5 inch, measure...
Googled your tires to be next Front: XL loadindex 91/ 1356lbs maxload AT 42psi Rear XL loadindex 102/ 1874lbs maxload AT 42 psi. This is for up to...
Dry air would chanche pressure with temperature chanche exactly the same. And the water in tire can only highen up the pressure 14.5 psi when...
First the weights : 1650 kg is empty weight with tank fileed, but no driver in it. this is devided 51% F and 49%R, so you calculated that out of...
@ otaki For the same tire you need to lower the Loadindex for higher speed. This gives in the end higher pressure, so lesser deflection so...
Googled your sise of tyre and found XL in 105 loadindex wich stands for maximum load of 925kg/2040 lbs and official system gives for Y speedrated...
I am able to calculate a pressure advice for you but need some data for it. From car : 1. weights on axles , mostly Max permissable axle...
Tire pressure is somewhat complicated then you assume. It is calculated with a formula that is introduced in 1928 for diagonal tires, and adjusted...
Tire pressure advice is calculated , using expected load on the tire, speed , and camber-angle ( alignment is when wheels are like this on the...
Mayby you can do something with spreadsheets and things I discoverd when being busy with calculating tire-pressure....
Been busy with re-calculating tire-pressure since 2007. Worked out a copy of the formula, the European tire-and car- manufacturers use, and...
registered specialy to give you an answer. I have been busy with calculating tyre-pressure since 2007 and learned myself Excell to make...
