[QUOTE=tinkerbell;1796920]10psi is a "few" psi?

Ok, on the 4th gen prelude the tyre plackard says for constant high speed driving inflate to about 40psi. now this is a cold pressue. my cold pressurs on the adrenlians were about 42psi, so 2psi over what honda recommends which is NOT a huge thing.
The hot tyre pressues of 50psi that I recorded at the track was from the same starting point of about 42psi. the reasion this rose so much was because of the soft compound and the fact that I was racing!. but yes this is high, but the actual wear on the tyres was good.

Alright for the lock up. I was going through a roundabout and some stupid driver did not give way and I forced jam on the breaks striaght away which resulted in a lock up. after I stopped I looked at the tyres and coud see a small wear spot/flat spot on the tyre from lockup. no this mark covered the whole tread area of tyre, thus when i locked up the whole tyre had good contact with the road, hence the pressure can't be too far off the right amount.

And for my Nankang NS2's with a max pressure rating of 44psi i actually have to have them below honda's tyre plackard rating for constant high speed driving.

Now I know that my tyres are over inflated a bit, but it is not at a dangerous or stupid level.
