i had a blowout with one of mine the other nite as you may have read the post? i was puttin 32-34 psi in them but when i got a new tyre fitted the next day the guy put 40psi in i said y put so much pressure in and he said he would not put any less than 40psi in an 18" tyre as they tend to heat up on motorways inside the tyre then blow up as i found out.Its quite a solid ride now but ide rather that than another blowout on the motorway at 80 or even quicker

40psi is way too much on your car mate
should be putting less pressure in as the air expands as it heats up tyre fitter was talking shit
