Here's the video. I know. I suck at doing these stuffs. :(
Anyway, I finally got 'em Yokohama Advan Neova AD07 fitted onto the ER34 over the weekend. Like before, the fronts are 225/40/18 88W while the rear are 255/35/18 90W. I got the rubbers fitted at this tyre shop that's kinda old skool. They use the manual alignment, caster and camber machine.

These are getting rarer by the days as most shops use the electronic equivalents. I dunno about your guys but I prefer the manual way. Looking at the old tyres, gosh they are really goners. It's worn down to the thread wear indicators (TWI) all round. The side shoulders of the front tyres are completely gone from perhaps all those hard cornering. They're cracked at some portions too. Surprisingly, the rear wears out pretty even.

On balancing the wheels after fitment of the new rubbers, the rear wheels are balanced via machine while the front are balanced on-wheel. Balancing the rear wheels (LSD rquipped) on-wheel will invariably kill the viscous coupling, the differentials and probably the gearbox too. So be warned. :O
Oh btw, many people or rather almost everyone will not bother to line-up the marking on the tyres to the air valve stem. This match-mounting procedure is to ensure that the lightest weight of the tyres should be aligned with the air valve stem on the wheel assembly, which represents the heaviest weight point of the wheel assembly. After match-mounting the tyre and wheel assembly can be easily balanced. Perhaps not that important or makes that much of a difference but then again, I'm quite picky. LOL :D
Here's some pictures...
