So theory would say I can’t put narrower 8.5” width on the rear even though the spare is a 245/35R20 black forged alloy (like the front) BUT actually carries a temporary wheel sticker on it. The fact this spare carries a temp wheel sticker seems to reinforces the narrower bueaurocratic view of model (yuck).
The yellow sticker has bugger all to do with bueaurocratic views....It is put there, incase you have a different sized wheel/tyre assembley fitted to the car, which is different to the spare and you happen to get a flat tyre, which the opposite axle has the larger rim/tyre fitted...It forwarns you, that the car WILL handle differently, therefore caution must be used and speed reduced as a result of the different handling.
You are able to place 4 of the same rims and tyres, complete with stickers on the car and drive at highway speeds and NOT be in the doo doo as a result....It is also not limited to the make/ model of the car....There are literally hundreds of makes and models out there with spares, which have this sticker on them....If memory serves me correctly, around the 2003 model commodore (VY???), they had temporary stickers placed on 15X6 steel wheels, fitted with 205/65X15 tyres, when the car came with a larger rim/tyre assembley fitted to the car....Now we all know, 15X6 wheels were standard fitament to this era Commodore...
