My srx caddy is very loud...engine or tires problem??

What is your question?

Lately, my Cadillac seems very loud while driving...no clunking but just not as quiet as when I bought it. We did change the tires, so wondering if I have a rear problem or not.

What makes this problem better or worse?

simply very loud wile driving

How long has your 2008 Cadillac SRX had this problem?
