Tyres for wet meadow

Hello, I’m new here and new to the four-wheel drive. I bought a 2007 CRV Diesel and need summer tyres. Winter tyres on rims are on it. I’ve already read a lot in the net, but I can’t go any further. Drive about 25,000 km/year and have nothing to do with the terrain. When I read tests of road tyres, the result is always good in the light terrain in the dry. In wet weather conditions. My wish is a road tyre with which I can drive with the trailer into a wet meadow. I think that with normal summer tires the four wheel in wet grass doesn’t get much further than a front drive. Hang now on all-year tires (only for the summer). Is there any good advice from you? If someone still has wheels left, I am happy about an offer. Greetings from the beautiful Allgäu Martin
