hey,

i currently have Yokohama A048R's - 165/55 R12. i was wondering if there was a optimal tyre pressure to run in the rear tyres. Currently i have 19 PSI in the rear and they still seem quite firm. There is no weight over the back, i don't take people in the rear seat, i don't carry a spare tyre/jack around town, i have a small light weight battery. Is is absurd to run any lower?

Thanks,

Bill

Not sure about 12" wheels but I run 28psi at the front and 26psi at the back, slightly more if going for a high speed freeway run. 19 sounds way too low to me...

32 psi front and 28 psi back is what I recommend , two recommended factory pressures for 3.5x10 and 4.5x10 were 26 front 24 rear and 28 front and 26 rear , I tried on my Mini S the latter but have moved up to 32 front and 28 back and I,m not going to change anytime soon

Just cause they look right don't make them right. It's because they have strong sidewalls to prevent rolling over in heavy cornering. I suggest you pump them to at least 25psi

I've always run 32/30 in all my minis

My mechanic runs the same on all of his mini's too!

I always put that little bit extra, because I know it will have leaked out by the next day anyway ;)

Well it's up to you hoenstly, it's your car, your tyres and quite possibly your life if you do a corner too quickly and the sidewall collapses resulting in disaster.

All I know is, there is a BIG handling difference between 25psi and 32psi in my car so I'd hate to think what it would handle like on 19psi...

:?

When I first bought my car, I drove it home from sutherland to blacktown on 8psi

I thought it was just the no power steering..
