If you check my RVTireBlog I have a post on how I set my TPMS.

Hello & sorry to bother you. Did a search, but could not find the answer to my question ( actually my brother's question ). He just bought a tire monitoring system. There is no clear instruction about how high/low tire pressure should go or how high temperature should go before an alert is triggered. Specifically, he has Goodyear G614 tires. But is there a rule of thumb for any tire?

Just saw you have a blog. Looks to be packed with info. I suspect I will find my answers there. Many thanks.

Thanks,
Fred
