What's the weight difference between the 20" factory rims and the 18" police rims?

My steel police wheel plus a 245/55ZR18 CONTINENTAL EXTREMECONTACT DWS 06 PLUS tire weighs 68lbs.

Yes, that's about right. I posted both pictures with both wheel setups on the scale for reference. I had seen this discussed and wondered about, saw a lot of "probably about"'s so i decided to help put the question to bed while I was making the swap.

Also, tirerack stated my tires weigh 28lbs. but they weighed 29.5lbs.

There will always be small variations in tire weight between factories and pour batches. The higher the quality the tire usually the less variation there is in the weight of each tire.

Factory 20" rim with a 255/45ZR20 tire (62 pound 5 oz) next to an Explorer interceptor rim with a 255/55R18 tire (69 pound 6 oz) including center cap. The 20 has a decent quality all season, the 18 just has a budget friendly all season. Road feel and hard cornering are reduced with the 18's. Ride comfort and overall daily driver enjoyment on typical pothole ridden poorly paved roads is 100% better with the 18's.

thanks for this nice add
