I run my 19" at 35 f & r (Yoko Advan ST's). Tyre shop that fitted them recommended 40 f & r. I noticed on the wall of the tyre 40psi maximum inflation. Tyre wear is v good and even, I do psi and visual check of tread every week.

Maybe Disneygrad should check recommended max inflation stamp on wall of tyre.

No.

Who are you talking to here?

The 20" rims I'm running are with Toyo Proxes. The instructions on the sidewall say Max Inflation was 50psi. Go figure!! :dunno:

O.K., I mis-spoke in earlier post. I said 42psi but after checking the max inflation of 40 psi., on the tire wall.. I checked each individual tire and they were inflated precisely at 40psi.. But now, I am begining to doubt every source and so as not to give X5 Meister further angst and tacacardia....I bled them back to thirty-five (35) psi.. But as I realize it, these are thin walled high performance tires so I've come to find there is a whole race and high-performance community that swears by the higher inflation specs for these tires. I'm just a little old man and had to have nurse Sally give me a shot of demerol to be able to change-out the psi's. Whew.... STILL love my X5 though. LOL

It's tachycardia.

Yes SIR!

X5 Meister, I've got a grandson just like you!! Always appreciate being set straight by someone who knows stuff though. Keep up the good work. LOL......
