I keep throwing toys in the playpen but I think it's all good : Tyre dude was telling me how he mounts tyres on wheels and said the yellow or white mark was to do with weight.. he didn't know the red marks tho but said they meant something also google informed! www.yokohamatire.com/tires-101/advanced-information/match-mountingyellow or white means the heaviest spot, and could be positioned relative to a valve in order to balance it out. (might be opposite the valve, might be with the valve - depends on the weight of the valve) red mark means where the highest uniformity is, in case your wheel itself has a run-out indicator mark... in which case you can put the most uniform part of the tyre near the least even part of the wheel, giving smoother running many wheels have no run-out marks indicated and few tyre places have a run-out dial along with the balancing machine, so yellow is easiest. the more you know (tm)

I used to think they were the QC/QA marks.

Going to check mine later, see if they're on properly.

I thought the white mark was meant to go opposite the valve, to balance out the wheel...

Depends on how much material there is in a valve vs was removed for the hole the valve sits in.

Oh aye, I get you. Looked at mine and the fitter totally ignored them.

Interesting, I was wondering about this when I got my new rears fitted, everyday is a learning day.

Yeah, I find it ridiculous that most tyre fitters don't CanoeING KNOW THIS. LIKE SERIOUSLY.
