tyre cock up?

Evening folks, had a slow puncture in a rear tyre, couldn't be mended due to 2 nails in outside edge. I left car with garage while they got prices (their supplier opened at 9am, but it was only 8.20 so couldn't be arsed waiting) anyway, I made the rash decision to just replace the punctured one with a budget tyre and I'l replace both rears in another 3k miles or so. Budget tyre is 225/50 r16 96v, all of which I think is fine, but I've now noticed its a 7j on my 8j d90. So do I now have a stretched tyre fashionable in vw circles and most importantly is it safe?
I,ve tried internet for info and the tyre supplied seems appropriate in all aspects except the 7j bit. Have the garage made a cock up and do you think I'm entitled to complain?
Regards, craig
 
Errmmm?

7J and 8J refers to the wheel rim width. The tyre can be mended too, so dont throw it away. Youll need to find a repairer (almost certainly not a tyre garage or 'fast fit') who can make a specialist hot vulcanised repair.

I think its OK, 225mm = 9 inches (25.4mm x 9) therefore if you have an 8J rim the tyre will not be per the VW scene...

The OE sizes for a 1989 944t are 225 front and 245 rear and the rims are 8's and 9's

Remember too that the 205-225 designations refer to nominal sizes, but that one manufacturers 215 can be a good deal wider than anothers 225.
 
I think you've misread Simon, the new tyre is on and the old one chucked.
George, its a 1991 s2 so rear of 8j is correct and my wheel is definitely an 8j. All the usual websites, black circles, mytyres etc say I should have a 225/50, which is what I've got, I'm just confused why it says 7j on the tyre and if its unsuitable

If the tyre has 7J written on its side then I would guess that 7J falls within the centre of the suitable rim widths. A range would be more usual though (6.5" - 8" for eg).
 
7J usually refers to the width of the wheels, I've not seen this on tyres before. 225 section is the standard fit for 8J wheels so I dont see an issue. More of a worry to me would be having odd tyres on the car as this can affect grip levels at differing levels in each corner, but if your are replacing both rears in 3k then I doubt it will really matter.

I've worked in the trade and have never seen a marking such as "7J" on a tyre. That's not to say things havn't changed since then. When stamped on a car wheel then the number refers to the width in inches, as has been said. The letter refers to the bead pattern of the tyre, virtually all road car tyres use "J" so don't worry about that too much. If the tyre that's been fitted is the same size as the one that came off (and the other rear) then all's ok. Mismatched tyre brands/models can cause suprises but usually you have to be really pushing it to make it a problem.

If a puncture's in the main tread then it can probably be repaired with a simple plug. On the sidewall or right on the edge of the tread is a no-no. Alot of it depends on the particular model of tyre and the experience of the fitter.

As for the "stretched look" I have a VW Corrado and the only thing I hate about it is the VW fashion victims, rat look and all that crap. If your tyre looks as it was designed to look and not like a condom stretched over a pint glass then it's probably not VW look..

 
Google "hot vulcanised repair". It is incorrect to state that a tread edge or even a sidewall (where cords are not cut) cannot be repaired. They cant be repaired with simple plugs that tyre garages offer, that is true; and require a more involved specialised procedure.

With regards to stretch: a small degree of stretch is ideal!
 
thanks for the advice so far folks, very helpful. Why is a small amount of stretch ideal please?
the comparison between my new budget and the punctured proxes are 225/50 R16 96V & 225/50 ZR 16 92V respectively. Not sure what the additional Z relates to on the Proxes, but the 96 refers to how much load the tyre can take so the higher the better? here's a pic confirming the 7J bit on the tyre.
