I took some new wheels and tires to a shop to get them mounted and balanced. When I got them back, he said there was no reason to balance the rear wheel. Not that it didn't need balancing, but that there is no reason to do it. I thought this odd, so I checked my original wheels and tires (still on my Primavera). There are no wheel weights anywhere (from new).
I've read a few posts about GTVs and the lot and while some people are adamant about balancing their tires, others have stated that it doesn't make any difference.
Any new thoughts?
