Pirelli Tires

[Guest]

I wanna' mount my new Sport Demons....does the yellow dot on the sidewall indicate the heavy spot or the light spot?
Thanks,
Hugh

Yellow spot is lightest and usually lined up with rim's valve spot because it's usually the heavy spot of rim. I spun my rims a few times before mounting my new tires and found the REAL heavy spot and this did not always line up with where the valve is. Then aligned it there with my tire's yellow spot to make final balancing easier(sometimes you luck out and no balance weights needed!)

Thanks, Lurch!
My wheels were actually perfect BEFORE the valve stem was installed...now the stem is the heavy spot.

Sorry, just to clarify that when I referred to valve spot, I meant that is WITH the valve stem installed is usually the heavy spot before the tire goes on. When I changed my tires I did not replace the valve stems and spun the wheel with it on and found that one rim's heavy spot was not where the valve stem was. So I aligned the yellow spot(lightest) on the tire with this spot on the rim(heaviest). One tire did not need weights added to balance but the other tire still did.
