so went to the garage the other day to check the psi in the tyres as i hadnt done it since the snow and they were all over the place. so i put 30psi into them all,
but got me thinking, what psi do you lot put in and why??
i know some over-inflate for breaking traction and some keep them a little low for more grip, but what you you say is the ideal psi on a low profile slightly stretched tyre

65.... must be for a bit of slideing tho tom.... surely was like a top fuel jobbie going down the road..:D:D:D

she was a welded 316 haha it needed all the help it could get:):)
30 in the front, 60 in the back!
on the road anything from 28-32 allround but on track around 55-60 in the rear tyres, i have a option dvd here going in to all the different tyres and psi they run in d1 i think the lowest was 55psi and the highest 72psi in the rear if i remember correctly
im guessing it would have a lot got to do with the grip level of the tyres they use as to what psi they would run to try and get a good balance for the driver
On the track it obviously depends on alot of different factor, wet/dry especially. I used always run 25psi on the front cold, with kumho track Tyres, and anything from 50 to 65 in the back, but those pressure on the back dropped to 30 in the wet. Worked grand for me.
holy shit 65psi !!! i run 30 usually all round
but surely when spinning the wheels up during drifting the psi would increase due to the heat no?? thats mad putting in so much air!heroes haha
Ya it would rise alright, but with a standard rb20 it's the job, infairness I think I only did that once or twice in watergrass hill where the runs are short and the track isn't really fast, did the job and the federals never blew up on me, even though I do think it caused then to delaminate once alright.
For low profile on the road I'd be running 26 to 28 on the front and 28 to 30 on the back for comfort. If your sliding put a small bit more in the back.
