BRIDGESTONE POTENZA TYRES

[sebrussellsmith]

I have just bought and had fitted a pair of Bridgestone Potenza SO2a 295/30R18 . I have had these tyres before as they seem to last well.
The pair I have bought look different in that they are obviuously the same make of tyre as they are marked as such but one (as attached image) has a yellow mark and next to it has a number that ends in 015.
Should I be concerned that the tyres don't look exactly the same?. Is there such thing as tyres coming from the same batch?

The attached image is not great but you can see the number I refer to under the yellow spot[attachment=IMG_20160706_192426.jpg]

Any comments are welcome, thank you.

Not sure what the yellow dot means but the number is the date of manufacture I think, 5015. Week 50 of year 2015

Hi Seb
The below should answer the dot question.
"Since it is very hard to make a tire that is perfectly balanced, some tire manufacturers apply yellow dots that indicate the tire's light balance point and serve to help you balance the assembly while mounting the tire. The yellow dots should be aligned with the valve stem on both steel and aluminum wheels since this is the wheel's heavy balance point"

Thanks Andy,
It looks like the dot is approx 45• from the valve so it doesn't seem to be in line?

Don't worry a lot aren't, just take look in some new car showrooms[8|]

Thanks Andy and all for comments. One of my main concerns was the way the code was cut into the tyre. Pictures not that clear but you can see below the dot. It just looks very shabbily done. Perhaps this is the norm?
