Tyre mounting and the little coloured dots
#12
I had my front tyres rotated and rebalanced earlier today and as Ray discovered the results are predictable...
Front left before
Front left after
Front right before
Front right after
So in total I saved 90grams of weight on both wheels. my understanding is that unsprung weight is equivalent to 4 x that amount. So that works out at 360grams which is nearly 1lb
Worth all the effort ? no of course not, but worth it to get rid of a shit load of weights and the knowledgethat you have achieved something (albeit minor) ? of course it is

The new cars that go through the dealers i work in all come with sticky paper dots on the tyre and wheels, these are usually perfectly aligned but occasionally are a little out of sync, these Ihave noticed have a little more weight on the wheels to balance them, constantly telling apprentices how to mount tyres for best balance but it goes in one ear and out the other.
I always like to fit the locking wheel nut opposite the valve or at the valve depending on the wheel mount, doesn't do much I think but creates symmetry, pick git me.

I was out test driving new potential daily drivers on Friday - four main dealers had cars in their showroom with the yellow dot randomly positioned around the wheel.
You never know some time and motion man may have "discovered" it's cheaper to add weights than fir the wheel properly...

Recently had a new set of rears (AD08Rs) and I asked for yellow dots to be lined up having seen a vid by Speed Academy:
The fitter was aware but doesn't usually go to the effort of fully lining them up - the manual rotating of the tyre is hard work =)
Have yet to see another car with them lined up properly. Bear in mind that one side of the car won't show the dots once fitted when looking out for them
edit: having just had a quick look at the comments on that vid , the dude does get slated for some things but at least I learnt about the dots

Well, if it's that hard to place tyre on top of rim with yellow dot roughly aligned to the valve hole, bang the bead over the rim to start, engage tyre lever machine and press 'rotate', I suppose it's all too much effort, really.
The tyre shouldn't rotate that much (if at all) whilst being fitted.
