I recently purchased 20” wheels for my 340i bmw 2017 with new tires( not expensive, some Taiwan brand) and used rims(strada), Right after the installation I did a first ride, my steering wheel started shaking at 30-35 mph, I did have them balanced, all four tires in three different shops, I had them check the rims, no dents or dings, somebody said it’s bad tires, I put Michelin tires on and I got the same problem, I checked the centering ring too, help me with this problem please?
I know you're not going to like my answer but you need to put the factory wheels and tires back on the vehicle or buy a new set of OEM rims to fit the Michelin tires. Your problems started when you replaced the factory wheels and tires with cheap aftermarket wheels, that's the common denominator, so I recommend sending the 20'' wheels back for a full refund and buy a good set of wheels, your problems will be solved.
