RWD wheel spin

The comments seem to indicate that it isn’t an RWD issue. That leaves (1) my driving style, or (2) the tires. I’ve been driving for 25+ years now and have never really experienced wheel spin on acceleration from a stop before (maybe once a year?). With this car I get it regularly. I haven’t changed my driving style and developed a lead foot … so it doesn’t seem to be “me”. The one-year old tires have good tread and I purchased the make/model from Tire Rack based on them having good traction in rain and snow (used their ratings). That was my criteria. The tires were rotated and pressure checked two weeks ago as part of my regular maintenance. My 4WD LOCK mode is not meant for continuous use … so I might just try using it for these wet acceleration times and see if it helps. Else I might just replace the car since not only is it annoying, it is dangerous at a couple intersections that I use everyday and must merge into traffic quickly. Not crawl! Thanks.
