Sessantas - problem?
A couple of times I've noticed that after standing for a few days I get steering wobble above 80 which eventually smoothes out after a few miles. It's not noticable at the lower speeds during the warm - up period. The first time I noticed it I went and had all four wheels re-balanced but it's still there, as described. I have 225/40-18 Sessantas and am wondering if during the period of inactivity they are getting a flat spot which corrects itself after some miles? I recall Yokohama had a problem with this some years ago.
Has anyone else noticed something similar with these tyres when left parked for some days?

Seriously though, i have sessantas, although only 17s - and have never noticed this. It is rare that it stands for a day let alone a few, but next time it does i'll be on the lookout now!!

i had a set of tyres do the same on my old mr2, they were exactly the same size too and i was running them on 34psi so i upped the pressures to 40psi and never had any further problems i am not sure what brand they were but i do know that certain low profile tyres do rely on a higher inflation pressure.

I'll try upping the pressures (the ride's hard enough already on the Prodrive springs!)

I run 32 front and 30 rear. Revolution put 32 in all 4 when i left there.
The Vredestein webby quotes FULL LOAD pressures and not just like me, one person car or two at most. Tyres are better overinflated than under, that is why Vred quote higher.
I , on the other hand, check mine every week and so run "correct" pressures all the time.
imho 36 and 39, etc is far too high for them and certainly not required.
