No never under inflated.. i check them at leas once a month and they never lost air either. tHey are at a constant 29psi... The reason they seem low is because there now leaking last i check they were at 23psi... i'm suspecting they'll be flat soon...

Yeah i bought these michellen tire caddies where i store them i store them standing on a sheet of plywood up in my basement..

I dont know its really really odd... My front tires used to at the back and i just rotated them in April..

The really wierd thing is that last weekend when i went to go clean my car they were fine...

And throughout the week i always took the same way to school and there are not big or threataning pot hole.. So something isnt right..

So basically i went from having 4 perfect tires with 18,000 Km to 2 really cracked up f***ed up tires... I mean i hate to be the conspiracy theorist but do you think that some one could have done this ??

look at the 2nd and 3rd picture awfuly thin and straight for a crack kind of looks like some one took a box cutter to them... And as for the big chunks i dunno maybe they started digging into them...

I mean its either Harry Potter is pissed at me and cursed them with magic.. Or there defective(I checked the DOT numbers they were made within a week of each other).. or someone slashed them...
