Praying Dhuhr Late to Avoid Making Wudu Twice – Is It Permissible?

Assalamu alaykum wa rahmatullahi wa barakatuh, I have a question about prayer time. Sometimes, I take ghusl or make wudu about an hour before the end of Dhuhr time (for example, at 4:00 PM), and then I wait until near the end — I pray Dhuhr about 5–10 minutes before its time ends. Right after that, Asr time begins, and I pray Asr. I have enough time to pray earlier, but I don’t want to take wudu or make ghusl many times a day if I am still in a state of purity. My question is: Is it allowed to delay Dhuhr close to the end of its time, even though I could pray earlier, just to avoid making wudu again before Asr?
