TV Tires - PSI Conflicts

A little research on your part would clear up the confusion. Here is a reference that follows industry standards for replacement tires. Just use the information that is applicable to the tires being installed. Appendix #4 depicts the Auxiliary tire info label.

Your link isn't working for me. I have bought a ton of tires for my vehicles through 3 different tire dealers and not once have they mentioned relabeling my vehicle. However, I work for a school district where we have our own buses. The tires have been changed to a different size on the buses at the dealership. When that happens the dealer does change the sticker. I have asked about the stickers to the Oregon Department of Education inspectors and they told me as long as I am upsizing tires, I don't have to replace the sticker. So to go from a G rated tire to an H I would have to do nothing. No new sticker needed.

Upping the psi to the tires max rating gets you the max tow capacity of the tires that is on the sidewall nothing more.

Go to a lt tire when you can.

i'm looking to do just that right now. Have looked on line with no luck and went to discount tire. Current tires are p275 55r20 /// t ms looking for lt275 55r20 e. Closest discount tire gets is a nitto tire lt275 60-20 lre which is 1" taller. Changes speedometer (shows 2.2 mph below actual).
Should i coutinue to search or settle? Is it acceptable to only replace the rears now and wait on the fronts? Thanks for any insight.

I just noticed you were unable to open my reference.

Certification labels and tire placards are not replaced when replacement tires require different inflation pressures. In fact, only a vehicle manufacturer, their representative (dealer) or a certified vehicle modifier are authorized to change those labels/placards.

However, auxiliary tire inflation labels are authorized and there is an example of one in the reference I provided above (which still works for me). The auxiliary label is placed adjacent to the placard/label it’s supplementing.

As for going from a LRG tire to a LRH tire of the same size that uses the same load inflation scale there is no requirement for an auxiliary label because both tires would have the same load capacity at the same inflation pressures. It’s when a plus sized tire is used that has a different load inflation chart that the auxiliary label is needed.

Without a recommended inflation pressure for your tires you have no guide for under inflation which is a huge culprit in early failure rates.
