I will start by saying that i love my jaguar. it is the best car i have ever had, with one exception. this is now the fifth incident of cracking rims (size 7.5x180 et52.5) on my 2005 jaguar x-type (equipped with the sport premium package). i went out to put the garbage out on sunday, 20may12, when i noticed the front driver's tire was low. i checked the pressure, and the guage showed 0. that night i put in 40 psi of air. the following day i checked it again, and the guage showed 20 psi. it is important to state the vehicle had not been used since 19may12 to that point. i jacked up the car, and pulled the wheel off the car. after spraying with soapy water on the inside rim by the sidewall, i found it was bubbling. i put the spare on the car. later i switched the spare so it could be on the driver's rear (so it would not be on a wheel thet steers). on a whim, i checked the wheel that was on the driver's rear side and found it was cracked as well. i sprayed soapy water and found it was not bubbling. i called the local jaguar dealer, who stated they have not had issues with their rims, and no recall has been issued for them. i find the cracking rims to be a huge safety issue. my wife and i have spent approximately $600 on wheel repairs. every factory original wheel on the car has been cracked; some more than once. we have also spent a lot of money on new tires because the rims were cracked and destroyed some of the tires' sidewalls. the most recent cracks were docummented via photos from my iphone. i have heard of other people having issued with their jaguar rims, yet i have not seen a recall on this item. it really should be. this is the car we take our four-year-old to daycare. we also use the car for family outtings and shopping. *tt
