Tyre Pressure For Toyo R888
 

As above what tyre pressure should i put in my toyos there 205s 50 15 and 195 50 15 on a mk4 fiesta (sub 800kgs 65/35 Weightish)

Thanks,

I normally run between 28 and 30 hot.

I used to run 25psi cold.

I depends alot on the car to be honest the weight the power the driven wheels.
When i'm hillclimbing in the dry I run 28 psi in the front and 26 psi in the rear.

luke on llandow you will find it better to run nearly all tyres at different cold temps. front left gets hotter than all the others as you know.

what i do is front cold 28 and rear 29 for first run then pit and check pressures and lower them when their hot to around 30-32. this way you save the faff of guessin cold temps.

i run rears higher than front for less rear grip usually 34 to 35 hot. when your tyres go cold later you can check the cold temps and start on these for future. just avoid hitting curbs hard until after first few laps.

Sub 800 is a very light car

On my pug which is 270+Bhp and 850-900 kg's

I run 29 hot
Next track day I'm going to try 28 hot on front


It also depends how you want the car to handle
