Hello, I have 215-45R17 ProEXS 4 Plus tires on my 2006 Jaguar X-Type VDP. The door sticker says to run at 38 psi in the front and 35 psi in the back. These psi measurements are for the stock tire 225/45R17. Should I still operate at the suggested psi? Thank you for your help!
I would stick with the stock tire pressure as long as your tires are rated to take 38 psi.
Max pressure is 50 psi. I just want these tires to last. They were expensive. Thank you for your time!!
The difference in tire size is tiny so not much to worry about. I personally recommend going up a size or so but not down sizing. Keep an eye on the tire wear and keep them rotated.
Although stock tire pressures are always the best place to start, I usually run mine 10% over inflated from stock and seem to have better tread wear. I have never had the center wear out first. Never exceed the maximum cold inflation pressure listed on the side wall.
Living in the mountains I run tire pressures on the high side as it improves handling and helps keep the tire edges from wearing.
