does any have a definitive answer to what pressure we should run a 2.8qs saloon (with auto box), running 225x40x18s ?
i couldnt get straight answet out of my local tyre company, and eveyone seems to have their own opinion and they vary wildly
Personal choice as much as recommendation.
If you dont like how it feels change it till you do
I run lower front pressure by 3-4psi 33 - 36 as it counteracts the understeer already dialled into the chassis set up.
I also tend to have a lot of crap in the boot, like 200kg of sand and cement the other day
Dude, you drive around with 200Kg in the boot? Thats insane. It's lie constantly having two large people in the car.
What impact does running higher pressure have on MPG?
1999 S4, MIJ Performance exhaust with 100 cell cats
Reduces it by a little.
I tend to stick an extra 2-3psi in when im heading on a long trip up the motorway, as it usually gives an extra mpg or two.
its a working vehicle and will die working....
