Thanks for the response, I imagine the 19" being a couple lb less. Manufacturers post all the details of their tires luckily. The FE Bridgestone are about 30 lb each if you +1 aspect ratio (OE size specs not available). So the 20" wheels are close to 43 and 48lb. I live in Minnesota so having dedicated winter and summer sets of tires and wheels is worth the $$ so you don't end up dead and frozen ina ditch somewhere in the winter, or simply just be able to make it to work on time. Lol. Either way hope someone is willing to experiment a little with me. Or better yet for me. 🙃Well, if you can find the weight of the tires I believe someone weighed the 20" wheel tires at 63 and 68 lbs with the wheels. I don't think the weight of the wheels is really going to give you range vs cost in the long run as you will probably be looking at a couple miles range vs a lot of cash for wheels of that size to carry that weight.
