Re: Mixed Tire PSIs
Thanks for the quick responses! Overall, it sounds like I might be OK until I brake hard, but I really should replace the other two tires on the front axle so that I have four identical tires. We have a short trip (200 miles each way on interstate) planned next week, so I am going to risk it and tow it with the two different load rating tires (and hence PSI) - to avoid the hassle of changing the tires and $275. Ben Franklin's words are echoing in my head: "Pennywise and pound foolish". At least the tires are both radial, from Carlisle, and have the same tread pattern. Thanks everybody!413Views0likes0CommentsMixed Tire PSIs
I have a double-axle trailer and replaced the rear axle tires. I now have Carlisle RH on the front axle and Carlisle HD on the rear axle. The RH has a recommended pressure of 65 PSI and the HD has a recommended pressure of 90 PSI. Should I run the two sets of tires at their recommended pressure, or should I run the rear tires at 65 PSI to match the front tires? My concern is that if the back tires have 90 PSI and the front tires have 65 PSI, won't the back tires end up carrying 30%-50% more load than the front tires? And if they do, does that matter? I called Carlisle tire, and they recommended running each set of tires at their recommended PSI until I make the permanent fix and replace the front axles RHs with HDs. Thanks, Bill5KViews0likes25Comments
